Do-it-yourself insulation of the veranda from the inside with a detailed description from a specialist. How to insulate a veranda yourself: increasing the frost resistance of a summer structure How to insulate the walls of block extensions inside

In harsh climates, owners try in every possible way to insulate their house or cottage. For example, a veranda is installed to protect the front door. This is a kind of vestibule where the mixing of cold street air and warm air from interior spaces. But when insulating a house, they do not always take into account that the veranda could use additional insulation. Otherwise, the unheated room will freeze and become damp, causing the finishing to quickly deteriorate. With the right approach, the veranda is insulated during the construction stage. But it happens that the house was not built, but bought, and not in the best condition. In this case, insulation of the veranda from the inside is carried out with your own hands as necessary. The main thing is to know in what places the cold “creeps” into the room and take all possible protective measures.

Usually the veranda is placed on the same type of foundation as the main building - monolithic concrete or concrete plates. This material does not block the cold that comes from the ground in winter at all, so it can freeze through. Heat loss through the foundation reaches 20%.

Options for how to insulate the base summer veranda, maybe several.

Filling the interior with earth or expanded clay

These options are only possible at the stage of constructing the veranda, when foundation work is underway. After removing the formwork, the entire internal area is covered with earth or expanded clay. Land will be cheap, especially if there is a lot of excess soil left during construction. True, its heat saving quality is low.

Expanded clay layer prevents moisture and frost from penetrating into the concrete slab

Expanded clay has higher thermal insulation, but you will have to buy it. You can make a double layer: first fill it with soil, and the second half with expanded clay pebbles.

Pasting with polystyrene foam

For Russian lands, where 80% of the soil is heaving, external insulation of the foundation with expanded polystyrene is necessary. When thawing and freezing, such soils expand in volume and can deform the foundation. The insulation layer will become an insulator, which will relieve the base from direct contact with the ground, and will also block frost. Expanded polystyrene boards are used to cover the entire outer surface of the concrete, including the base.

For insulating a veranda with your own hands, the following are suitable: polystyrene foam, extruded polystyrene foam and liquid polyurethane foam. All these are varieties of polystyrene, which differ in properties and method of application. The cheapest one - Styrofoam. It retains heat well, but will crack on moving soils. In addition, polystyrene foam draws moisture from the ground, so when installing it, an additional waterproofing layer is created (from the soil). Extruded polystyrene foam Due to its dense structure, it does not absorb moisture, is not afraid of soil movements, has high frost resistance and lasts for more than half a century. But it is expensive.

Before gluing expanded polystyrene, it is necessary to cover the entire foundation with waterproofing mastic

Both versions of polystyrene are laid on the outside of the foundation, excavating it to the very foundation. In this case, the first row is placed on a gravel bed. Before laying, the foundation is coated with bitumen-polymer mastic (for waterproofing), and when it dries, polystyrene foam boards are glued on. The glue must be polyurethane. It is applied in dots or by smearing the entire sheet. The joints between the plates are also glued so that there are no cold bridges and cracks for moisture penetration.

The newest method of external insulation is polyurethane foam spraying. It is brought to the construction site in the form of liquid components and sprayed onto the foundation using special equipment. After hardening, the coating becomes dense, monolithic and very durable. In terms of characteristics, this material is not inferior to its extruded “brother”, but the cost of work is more expensive.

With sprayed insulation, the most best quality thermal insulation because there are no joints

To keep your feet from getting cold: floor insulation

Besides the foundation, the floor is closest to the ground. Its insulation is mandatory if you do not want to see black spots of dampness in the corners.

Most often, concrete floors are poured on verandas. If you plan to heat the veranda using a “warm floor” system, then you should take care of it already at the stage of pouring the subfloors. It's best to choose an electrical system that you can turn on as needed. A water floor can be very low temperatures freeze, and you will have to wait until spring for it to thaw, or dismantle the coating to warm up the pipes.

If there were old tiles on the veranda, then you can lay the insulation directly on it

Let's look at how you can insulate the floor on an unheated veranda:

1. The entire underground floor is covered with crushed stone, and on top - with sand and compacted tightly.
2. Lay out reinforcing bars or mesh (so that the concrete does not burst) and make a concrete screed 5 cm thick.
3. When the filling is dry, we create waterproofing. The easiest way is to coat the screed with water-repellent mastic. But it’s cheaper to lay sheets of roofing felt and fasten them together using bitumen mastic (or heat them with a burner and roll them).
4. Antiseptic-impregnated logs are installed on top of the waterproofing, and insulation is laid between them. The best option is mineral wool with a foil-coated side. The foil does not release infrared radiation from the veranda, along with which most of the heat evaporates. Rolls of insulation are placed after all the joists are installed.
5. It can also be insulated with polystyrene foam. Then the joints between the plates must be blown out polyurethane foam, and when it dries, cut off the excess.

After this, planks or decking are laid, because both materials are warm. The board must be treated in every possible way to prevent rotting and painted. protective composition. Besides, natural wood very afraid poor ventilation. To avoid dampness, it is necessary to make ventilation vents in the foundation, which should be located below the floor level.

The insulation is placed with the foil facing up so that it reflects the heat back into the veranda

Decking does not require ventilation in the underground, because it is not afraid of dampness and temperature changes

Decking is also a board, but already treated with compounds at the factory. It is made from larch, which is not afraid of either frost or moisture. Open terraces are lined with this material, so it is even more suitable for a veranda. True, the cost of such a floor will not be cheap.

We install thermal protection for the walls

The walls have a large area of ​​contact with the street, so let’s look at how to insulate a veranda with your own hands from the outside and inside. External insulation is carried out if the wall material looks unpresentable. Those. it could be blocks, old wood, etc.

External insulation

a) For wooden walls:

1. We seal all the cracks in the building.
2. We place a vertical sheathing of beams on the tree in increments of up to half a meter. It is better to measure the width of the insulation and fill it exactly to its size. Then all the slabs will fit tightly to the sheathing.
3. We insert mineral wool between the beams, securing them with dowel umbrellas.
4. We fix the waterproofing film on top with a stapler.
5. We finish with clapboard or siding.

After laying the mineral wool, you need to staple the waterproofing film to the sheathing

b) For block walls:

1. We glue polystyrene foam boards to the walls with a special adhesive composition, additionally strengthening them with umbrella dowels.
2. We smear the same glue on the top of the slabs and attach the reinforcing mesh to them.
3. After drying, cover the walls decorative plaster.
4. Let's paint.

Select an adhesive composition specifically for laying polystyrene foam boards

All layers of the insulation cake are hidden under decorative plaster

Let's insulate ourselves from the inside

If the veranda looks aesthetically pleasing from the outside, and you do not want to change its appearance, then you can carry out internal insulation. But, before you insulate the veranda from the inside, you need to carefully caulk all the cracks (in a wooden building).

Work progress:

1. They stuff the sheathing.
2. Fix the waterproofing film with a stapler, which will prevent moisture from the street from entering the insulation.
3. Mount metal carcass from profiles onto which drywall will then be attached.
4. Fill the frame with mineral wool.
5. Cover the insulation with a vapor barrier film.
6. Installing drywall.
7. Apply the finishing coat (putty, paint).

The distance between the metal profiles must match the width of the insulation sheets

We check the tightness of the installation of windows and doors

Large heat losses can come from windows and doors. If there are old ones on your veranda wooden windows, but you do not want to replace them with double-glazed windows, then you need to thoroughly check their tightness:

• First of all, we pay attention to the quality of the glazing of the veranda: to do this, we pull each glazing bead.
• If they are cracked or loose, it is better to remove all the glass, clean the grooves and coat them with silicone sealant.
• Then we insert the glass back and apply sealant along the edge.
• We press with glazing beads (new!).

Go over the joints of the frame and the window opening with a regular metal ruler. If in some places it passes freely, then these cracks must be sealed with polyurethane foam. Check the front door in the same way. If you bought an uninsulated option, you will have to insulate the canvas yourself inside and upholster with leatherette.

Seal the glass on both sides with sealant to make it windproof.

All places where the ruler moves freely must be foamed

Eliminate leakage of warm air through the ceiling

All that remains is to figure out how to insulate the ceiling, because through it evaporates from the wooden veranda. Substantial part heat. Especially if it opens Entrance door. The flow of cold air rushing inward instantly squeezes the warm air upward.

The best option is to place foil-coated foam polymer between the beams, which will simultaneously retain heat and prevent moisture from passing through.

You can also choose mineral wool, but then the first layer is roofing felt for vapor barrier, and insulation boards are placed on it.

Ruberoid is laid under mineral wool for waterproofing

After such careful insulation, your veranda will withstand any frost, even if it is unheated.

It is necessary to be able to distinguish a veranda from a terrace.

Most often, wood is used to build country houses and dachas. Wooden buildings are very easy and quick to assemble. If such a structure is well and properly insulated, then living in it will be very comfortable even in winter.

Very often, owners add a veranda to their house on their own, where they can relax on a warm evening or hide from the scorching sun during the day.

But in cold and damp weather it is additional building practically not used.

To make the room more comfortable even in winter, you need to think about how to properly insulate a completed veranda from the inside, perhaps with your own hands.

People sometimes confuse a veranda with a terrace, let's take a short detour and look at which is which.

The terrace is an open area, so there is no point in insulating it. The veranda is an additional glazed building, so it should not be confused with a terrace.

The veranda, like the terrace, is not heated, so the air temperature in it differs little from the temperature outside.

How to insulate the floor on the veranda

If you are preparing a plan for building your house, it is better to immediately provide space for a veranda.

Thermal insulation of the floor on the veranda is one of the main stages of the entire process. Click on photo to enlarge.

Of course, nothing prevents you from adding a veranda later to an already finished house.

But with the first option, it is possible to provide a built-in veranda in advance and it will be part of your home. And the attached veranda will be located outside the house. Of course, both options need to be insulated.

Insulating the veranda from the inside should start from the floor. In wooden houses, it is most often made of logs laid on the ground, to which boards are attached.

To properly insulate the floor, you will first need to remove the boards.

Place wooden blocks between the joists and secure them with screws. And now we lay between the bars insulation material.

It is best to use mineral wool, penoplex or foam plastic as insulation.

It is very important that the insulation tightly fills all the spaces between the joists.

Sheets of foam plastic are very easy to adjust to any size of logs, since this material is very easy to cut with a knife.

Mineral wool must be insulated with polyethylene or foil before installation. This is necessary to ensure that the insulation does not deteriorate from moisture.

All empty spaces must be filled with special polyurethane foam.

The height of your insulation structure should be a few millimeters below the floor itself.

Air movement will constantly pass through such a gap, which helps remove moisture, ventilating the space, and you can avoid getting wet and rotting floor elements.

At the very end, we lay stretched polyethylene film on the insulation boards, the edges of which are secured with metallized tape. Only now can you lay the floorboards and move on to insulating other elements of the veranda.

Insulation of veranda walls and ceilings

How to insulate a veranda with your own hands if it is located inside a building? In this case, only the external walls are insulated. The walls that connect the veranda with other rooms no longer need to be insulated.

The structure of thermal insulation of veranda walls. Click on photo to enlarge.

Let us now consider the insulation technique of this option.

Initially, all walls must be covered with waterproof material. We glue strips of polyethylene or foil with horizontal lines. We close all the resulting joints with tape so that there are no gaps for air.

Then, taking into account the size of the slabs of cotton wool or foam plastic insulation, you need to stuff wooden blocks onto the walls. And now we place insulation between them, for example, such as mineral wool. Polystyrene foam can simply be glued to the wall surface using special glue.

Insulation with polyurethane foam

The easiest way is to insulate the walls with liquid foam, which is called polyurethane foam. This insulation ideally protects from the cold and will serve you for several decades.

It has the property of filling all the flaws and cracks with itself, creating an even layer of coating. But it is worth noting that it is not cheap, which is why it is very rarely used for private buildings.

Insulation boards must be wrapped in polyethylene foam. And if you use heat-reflecting material, then you need it metal surface place inside.

On top of this structure you can attach finishing material, such as lining and the like.

How to insulate a veranda from the inside so that the room can keep warm longer? To do this, you will also need to insulate the ceiling. Everyone already knows that warm air rises up. And if he does not encounter a good barrier, he will leave the room without hindrance. If you insulate the ceiling, then most of the heat supplied to the veranda will be stored indoors.

The ceiling of the veranda is insulated in the same way as the walls. The insulation is insulated from moisture, wooden strips are stuffed to secure the insulation, the voids are filled with special polyurethane foam, and all this is sewn up with clapboard or other finishing material.

If your veranda is mostly occupied by window frames, we recommend that you install a structure made of triple frames. Because heat loss for the most part goes through the windows.

Before you start insulating the veranda, you need to take care of fire safety. For insulation you should choose non-flammable materials, such as mineral wool. If a fire occurs, then your veranda, not protected by fireproof materials, will flare up at the slightest contact with fire and will burn in a very short time. a short time. Thus, during a fire, the veranda can become a real barrier for residents to escape.

If you have a terrace, then it is impossible to insulate it. You can simply make an additional structure that will protect you in windy weather.

The review describes an option for internal insulation of the veranda. But it is also possible to perform insulation on the outside of the extension. Such insulation will additionally protect wooden walls from wind and precipitation. This way they will be better preserved and last longer.

As you can see, insulating a veranda with your own hands will not be difficult; the main thing is to determine in advance what to insulate and with what, and then it’s a matter of technology.

In order to insulate an extension to your house, you will need good thermal insulation material. Optimal solution for internal and external insulation - mineral wool boards.

They are excellent for insulating walls and floorboards, have good thermal conductivity, are moisture resistant, durable and inexpensive. For interior work you need insulation with a thickness of 50-70 mm.

Insulation of walls and ceilings of an extension from the inside

List of required materials:

1. 1. Waterproofing film to protect insulation from moisture.
   2. Fasteners and metal profiles for frame construction and plasterboard cladding.

1. Wooden slats with a section of 5 x 2 cm.
2. Plasterboard sheets for final wall cladding with a thickness of 9.5 to 12 mm.
3. Putty for processing seams between plasterboard sheets.

Warming stages:

• Creation of lathing for attaching thermal insulation. On the surfaces to be insulated, we fill prepared slats or boards with a distance slightly less than the width of the insulating panels.
• Installation of insulation. We place mineral wool between the bars. So are the walls.
• Waterproofing. We cover the entire insulated surface with a vapor barrier membrane, overlapping the edges. We fix the film with staples on the sheathing bars.
• Frame for plasterboard sheets. We fasten vertical and horizontal metal profiles, creating a frame for the final cladding.
• GKL covering. We install drywall on the walls and ceiling.
• Note. In principle, instead of drywall, you can use other material for sheathing. It can be wooden lining, plywood, OSB or gypsum fiber board. Choose what suits you best in terms of external and internal characteristics.
• Processing of joints. Using putty, we cover the joints between the plates and clean them.
• Cosmetic finishing. The finished surface can be painted, covered with wallpaper, tiled or any other finishing materials.

Features of insulating walls made of certain materials

Walls made of foam concrete blocks are warm due to huge amount air bubbles contained in foam concrete, but additional insulation work cannot be done, otherwise heating costs will be too high. Insulating the outside is much more expensive because it requires cladding. Proper insulation walls from the inside suggests good vapor barrier and ventilation of the insulating layer on both sides.

It is recommended to avoid highly absorbent, fibrous, moisture-permeable insulation materials. These measures are necessary to reduce humidity in the extension and prevent freezing of the walls. When installing insulation, it should be taken into account that cold penetrates into the room through the joints.

Mineral wool is not suitable for foam concrete blocks; expanded polystyrene sheets require additional joining. The best insulation for such walls is spraying polyurethane foam. It prevents the formation of condensation. For education required thickness Wooden sheathing should be used for the insulation layer. The metal profile creates cold bridges. A waterproofing layer is secured on top of the foam with slats, and then drywall is attached. The dew point is located at the point of contact between the polyurethane foam and the foam block extension or inside the polyurethane.

Insulate in the same way brick extension, but the insulation layer for brick walls is larger.

The disadvantages of spraying polyurethane are the high price and the need to attract special equipment and trained specialists.

Insulating the walls of a frame extension from the outside

We do external insulation of an extension to a frame house according to the same principle as internal insulation. First, a vertical frame of wooden beams is placed on the walls. The distance between the boards should be about 50 cm, slightly less than the width of the insulation. Mineral wool blocks are tightly inserted between the beams, which are covered with a layer of waterproofing. The film is strengthened with staples around the perimeter of the frame. At the final finishing stage, the surface is covered with siding.

Outside or inside, which is more effective?

Advantages of internal insulation

• insulate the ceiling, floor, walls in one step;
• work can be performed in any weather conditions;
• simplicity - insulated surfaces are available throughout the entire height.

Disadvantages of internal insulation

Freezing point at internal insulation moves into the wall, which contributes to its faster destruction. In addition, if the extension room already has finishing, decorative coating will have to be dismantled.

Advantages of external insulation

• displacement of the freezing point in the insulation, due to which the rate of destruction of walls decreases;
• the internal living space of the extension is preserved;
• no waste from construction work indoors;
• the possibility of using the extension during work, the way of life is preserved;
• additional protection of wooden walls from getting wet.

You will not be able to observe the condition of the walls, since they will be hidden behind decorative cladding.

Insulation of concrete floor

List of materials you will need:

• insulation – mineral wool boards;
• vapor barrier;
• scotch;
• damper tape;
• reinforcing mesh;
• screed solution.

Stages of insulation

• On concrete base a layer of vapor barrier film is applied. The insulation joints must be carefully taped to ensure the overall tightness of the layer.
• On top waterproofing material Insulation boards are laid. It is important that the blocks fit tightly to each other, there are no gaps or cracks left.
• The entire perimeter of the room is covered with damper tape. This is necessary to compensate in case of expansion of the screed.
• Another layer of vapor barrier and then a reinforcing mesh is applied on top of the mineral wool insulation.
• The screed is poured. Its thickness should be at least 3 cm.
• After the surface has completely dried, any topcoat is applied.

Floor insulation on beams

List of materials - what you will need:

• wooden boards, logs;
• insulation;
• vapor barrier coating;
• clay mortar;
• plywood.

Stages of work

Secure to floor beams cross beams smaller size. Lay the boards on the joists with rough, continuous flooring to prevent heat from escaping. Coat the coating with a thick clay solution, wait until it dries and apply a layer of vapor barrier on top. Place insulation boards between the joists and cover it with another layer of vapor barrier. Cover the surface with boards or plywood on top. On the resulting wooden floor Lay the decorative covering to your liking.

Roof insulation

To properly insulate the roof of an extension to a house, the following principle should be observed: all layers of the insulation cake must provide moisture insulation on the outside and vapor permeability on the inside. For thermal insulation of roofs, polystyrene foam, penoplex, and polyurethane foam are used, but mineral wool and other fiber insulation in combination with membrane films for removing water vapor are best suited.

Types of insulation - features, characteristics

1. Mineral wool. It has low thermal conductivity, is fireproof, durable, flexible, and resistant to temperatures and chemicals. In addition, mineral wool insulation provides good sound insulation. Cons: a frame is required for installation, after some time of operation it becomes compacted and loses its thermal insulation properties.
2. Polyurethane foam is produced in three types: flexible, dense, sprayed. Polyurethane foam is easy to install, lightweight, and resistant to biological and chemical environments. Disadvantages - expensive price, quickly ages from ultraviolet radiation, deforms from mechanical stress, has a low vapor permeability indicator, which is why it accumulates moisture, which has a detrimental effect on the walls of the house.
3. Penofol is environmentally friendly, flexible, and easy to install. The material has low vapor permeability and high combustion resistance. Cons: thin, overly soft. Expanded polystyrene has low weight, sufficient rigidity, and is easy to install and cut. This is a very durable, wear-resistant material. Cons – can’t stand it high temperatures from 100 degrees, has low soundproofing qualities.
4. Basalt wool is a fibrous material whose properties and performance characteristics are identical to mineral wool. Disadvantages - during operation it becomes compacted, which increases thermal conductivity.
5. Foam plastic is light and hard, does not lose its operational properties even after prolonged use, it can be mounted either frameless or framed. Insulation with low vapor permeability and hygroscopicity. Cons: flammable, loved by rodents.
6. Moss, flax, tow - used for insulation without disturbing appearance the buildings. Such materials are certainly environmentally friendly. Disadvantages: they are specific, difficult to install, and are of interest to animals and birds that build their nests from them.

When insulating an extension with your own hands, it is always better to start with the walls. How to insulate the extension, will it be external or internal insulation, depends on the size, characteristics of the room and the personal tastes and preferences of the homeowners. The insulation process itself does not take much time, and the cost of materials for such work will not hit the budget.

How to insulate a cold veranda in a private house with your own hands?

If you added to yours in the summer one-story house veranda and, for example, equipped a comfortable kitchen there, and with the arrival of cold weather, the corners of the extension freeze and turn black - which means it’s time to think about how to insulate the veranda.

How to insulate a cold veranda?

It must be said right away that the problem of insulation will have to be approached on a large scale, that is, you cannot get by with wall insulation alone. It is necessary to work with both walls and floors, ceilings, and windows. Well, let's get started.

Perhaps we should start with a list of what we need for work. Insulating a veranda usually means that you will need, naturally,

Prepare:

• pencil, tape measure, nails, hammer, dowels, hacksaw, construction tape, spatulas and putty.

Well, buy insulation material:

• This could be penofol or some other analogue, polystyrene foam sheets (in other words, polystyrene foam) or mineral wool, basalt wool, polyurethane foam, or maybe resole foam.

All these materials have suitable characteristics. The thickness of the insulation layer will depend on the thickness of the wall of your extension. You will determine it yourself.

And yet, what is the best material to choose for insulation?

Most often, when insulating an attached veranda, mineral wool and polystyrene foam are used. The latter, upon possible contact with fire, will release very dangerous carcinogens, so this fact should not be ignored. Why is it still quite often used as insulation, because foam sheets are still the most affordable. This is a budget option.

As additional insulation, you can add a foam pad. With the help of a metallized layer, penofol will reflect cool air from the street, and it will also retain heat inside your veranda. This material is a high-tech thermal insulation product; it consists of a layer of foamed polyethylene and a high-quality aluminum foil covering it. This “reflective” material can even be used as a separate independent thermal insulation. But the maximum effect of heat preservation will be achieved by combining it with other types of insulation.

Effective insulation options include resol foam, basalt wool and polyurethane foam. These are non-flammable materials. Therefore, when you decide how to insulate the veranda, we advise you to pay attention to these insulation materials.

Step 1: insulating windows

Insulation of the veranda, like any other part of the house, begins with the windows. First, you need to pay attention to the windows. Do existing windows retain heat well? No? We are replacing! The old windows need to be removed and good, high-quality windows installed that will retain heat in the veranda.

Which windows should you choose - wooden, aluminum or plastic - this issue is described in a separate topic and after studying the materials you will make the choice yourself. In this case, the very fact that they will be better than your old windows in terms of thermal insulation properties is important to us.

Step 2: insulating the walls

When you have determined for yourself what is the best way to insulate the veranda, then this is the material you will use to cover the walls. On the walls (and also possibly on the floor) you attach sheets of insulation (polyurethane foam, polystyrene foam, mineral wool, etc.). Here you will need dowels with caps large diameter, you can also use small wooden plates to prevent the dowel heads from going into the foam sheet. If this happens, the insulation will no longer hold on. At the joints of the sheets, seal the cracks using polyurethane foam, and then remove the excess, and glue masking tape on top (you can use regular tape).

ATTENTION: use polyurethane foam without toluene. This substance destroys foam.

What is the best way to insulate walls: inside or outside?

Before starting work on wall insulation, many beginners (and not only) have a question: where is it better to insulate a wall, outside or inside? The illustration below will explain this point better than words:

although this is not immediately obvious to everyone, it is better to insulate walls from the outside

Step 3: laying a vapor barrier

This step is recommended, but not required if savings are important to you. It consists of attaching foil film. The vapor barrier is attached using glue or double-sided tape. A reflective foil layer will keep you warm in winter and cool in summer.

Step 4: making a cold floor warm

Finally, we install the floors. In theory, you need to lay a concrete screed. But you can simply lay the floor from boards and linoleum or carpet on top of it. If your budget allows, you can make a “warm floor”.

In addition, you can use the tips described in the publication about insulating the floor on the balcony.

The final stage

A variety of options can be used as finishing. For example, fix the lathing on the walls, and on top of it are sheets of drywall. What to do next with the now warm, cold veranda - only your imagination will tell you.

Review of materials used for internal insulation

Nowadays the construction market offers a wide variety of materials for thermal insulation of premises. They differ performance characteristics and cost. So, let's figure out how to insulate the veranda from the inside?

We insulate a closed veranda with our own hands

In this block we will discuss how to properly insulate a veranda from the inside with your own hands. Let's consider the features of insulation of walls, ceilings, roofs, floors, doors and windows. Before starting work, you will need to purchase all materials and tools, seal windows and doors.

Preparatory work before insulation

There are many ways to insulate a veranda with your own hands. We will tell you about the most popular methods among people. The list of required tools includes: stapler, construction knife, paint roller, hacksaw, paint brushes, screwdriver. Except the selected one thermal insulation material you will also need to buy: door seal, mounting foam, vapor barrier film, self-tapping screws, plaster, wooden beams.

When preparatory work finished, it's time to turn a cold veranda into a warm one living room.

Insulation of walls on the veranda

You should start insulating the walls on the veranda with the installation of a frame (metal or wood). The wooden frame is made of slats and bars, and the metal frame is made of galvanized profile. The latter is most suitable for insulating plasterboard structures. The technology for installing the frame is the same when using the materials listed above and looks like this (an example of installing a wooden frame).

Insulation of ceiling and roof

Internal insulation of the veranda requires the obligatory laying of a thermal insulation layer on the ceiling. The principle of carrying out the work is practically no different from the methodology for insulating walls. The main difficulty is that everything installation work need to be carried out under a canopy. Doing all this alone is almost impossible.

To begin, dismantle the ceiling covering and apply a waterproofing film to the rough surface of the ceiling. Next, you need to build a frame from timber according to the same principle as for the walls. A thermal insulation layer can be made in the gaps between the beams. The top is covered with a vapor barrier film. Finishing can be done using plasterboard or lining.

Most of the heat escapes through the roof. To reduce heat loss, high-quality insulation will be required. This can only be done from the outside during the construction phase. Work on the roof from the inside is only possible through the ceiling.

Insulation of the floor on the veranda

How and with what to insulate the floor on the veranda? One of the most popular plank floor installation schemes is as follows.

1. Cover the floor with expanded clay or small crushed stone.
2. Pour a small layer of sand on top and compact it.
3. Next do reinforcing mesh with a section according to your project.
4. A concrete layer of thickness according to the design is poured on top.
5. After the floor has dried, lay a waterproofing layer, for example, roofing felt.
6. Wooden logs impregnated with antiseptics should be laid on top of the roofing material.
7. A thermal insulation layer must be placed between the joists.
8. After insulating the floor on the veranda in a wooden house, you should proceed to laying the finishing coating.

Insulation of windows and doors

The best option is to install PVC double-glazed windows. If this is not possible, then you can start insulating existing wooden frames.

Preparatory work should be carried out in the following order:

You also need to insulate the door frame so that cold air does not pass through the joints onto the veranda. Do this using batting: remove from the loops and stuff slightly protruding rollers on top and bottom, and then beat tightly, securing with a stapler or small nails.

Options for heating a closed veranda in winter

Answering the question how to do it warm veranda with our own hands, let's look at the most popular and available options heating closed veranda in winter.

Insulating a summer veranda – does it make sense?

To turn a summer veranda into a full-fledged room suitable for living in winter, you will need to carefully insulate the veranda with your own hands from the inside and outside. The only “viable” option is to make frame or frameless glazing of the veranda and terrace. But then you will have to spend a certain amount of money: first on installing double-glazed windows, and then on insulation with the help of thermal insulation materials.

When insulating a summer veranda, it should be taken into account that the installation of a heat-insulating layer leads to a shift in the dew point. This causes the formation of fungus and mold. Therefore, it will be necessary to lay a waterproofing and vapor barrier layer

master class from an expert with photos and videos

The veranda in every home is a special place. It’s nice to spend time here in the summer, but in the cold season it’s difficult to call such a room comfortable. Therefore, every owner strives to solve the question: how to insulate the veranda for winter living in advance.

The best way to insulate a veranda: types of materials

There are many materials that allow you to efficiently insulate your veranda. But among large selection there are a few that have proven to be better than others.

Penofol

1. This insulation has a foil layer, which is additional protection from the cold in a wooden veranda.
2. Penofol can be used either independently or combined with other similar materials.
3. The insulation is environmentally friendly and does not emit toxic substances.
4. Easy to install and considered a fireproof product. It is great for insulating a veranda in a wooden house.
5. It reflects cold air from the street well.

Styrofoam

1. Polystyrene foam is perfect for insulating floors, walls, and ceilings.
2. Insulating a veranda with polystyrene foam is quite simple. Installation of panels can be done either by mechanical fasteners or using special glue.
3. Thanks to its structure, this insulation creates coolness in the room in summer, and keeps heat inside the veranda in winter.
4. This material is non-toxic and insects and fungi do not like it. Therefore, it is often laid under the floor screed or behind the drywall. As additional insulation verandas you can use penofol.

Expanded polystyrene

This product is similar in properties to polystyrene foam. It is very durable and easy to process. An excellent product for insulating a veranda.

Mineral wool

1. This insulation is considered “breathable”. It provides additional air exchange, thereby reducing humidity in the room.
2. Mineral wool is an environmentally friendly insulation material. It is absolutely harmless, odorless, and does not emit toxic substances.
3. Mineral wool is a fire-resistant material. It is especially good to use it for insulating the veranda if the building is wooden.
4. This insulation has proven itself well in the field of water resistance. It is able to repel moisture, which allows you to regulate the internal microclimate of the room.
5. Mineral wool is also an excellent sound insulator. It dampens noise in the veranda coming from the street, thereby providing additional comfort. This insulation is used to insulate walls, floors, ceilings, and ceilings. A wide range of products allows you to choose the best option. This product can both insulate a veranda and a wooden house as a whole.

Basalt wool

This insulation is in no way inferior to mineral wool. It also perfectly protects the house from cold and noise. Excellent resistance to chemical and biological influences. Insulating the veranda with this product has proven itself well in extreme frosts.

Polyurethane foam (PPU)

Such insulation can be purchased in three types: rigid panels, flexible plates and inflatable. The advantage of this material is its low weight and ease of installation. But it does not tolerate mechanical stress well, and has a high price.

Flax, tow, moss

Such insulation is used when the veranda is wooden. It is difficult to install such materials. If you plan to insulate the veranda with this raw material, then it is better to do this during the construction of the veranda.

Synthetic insulation for construction

Artificial material has more durable characteristics than natural ones. This material is used to insulate the veranda from the inside and outside. It is successfully used to insulate walls, ceilings, and floors.

Do-it-yourself insulation of the veranda to the house

The veranda is almost always built on the same foundation as the house. As a rule, this is monolithic concrete or concrete slabs. In winter, about 20% of the heat escapes through it. Therefore, before insulating the veranda, you should insulate the foundation. It is not difficult to make such insulation. It is necessary to cover the surface (including the base) with polystyrene foam boards.

Don't buy cheap foam. It absorbs moisture, so in places of contact with the ground it can simply crack. To prevent this, it is necessary to make additional waterproofing with a film between the ground and the insulation.

1. Foundation wooden house dig up to the base and coat with bitumen-polymer mastic.
2. After this, a layer of polystyrene is placed on a gravel bed and glued to the surface of the foundation with polyurethane glue.
3. You should also coat the joints between the plates with glue. This is necessary to prevent the penetration of moisture and cold.

Insulation of the floor on the veranda

Insulation of the veranda begins with thermal insulation of the floor. Mostly in such premises they do concrete base, this can be clearly seen in the video. If heating a wooden extension is planned using the “warm floor” technology, it is better to choose an electrical system. It can be turned on as needed. Water heating should not be installed on a wooden veranda, since at low temperatures the pipes may freeze and become deformed, as a result the system will have to be completely changed.

Floor insulation in an unheated veranda

The floor of the house is closest to the ground and if it is not heated, a significant part of the cold enters the wooden room from below. Therefore, when deciding the question: how to insulate the veranda, this part should be insulated first. The procedure for insulating the floor on the veranda.

1. At the first stage of insulating the floor of the veranda, crushed stone is poured, sand is placed on top and compacted well.
2. Next, they make a frame and lay down mesh or reinforcing bars. This is necessary so that the concrete does not burst later.
3. Then concrete is poured in a layer of five centimeters.
4. After the screed has hardened, the floor should be waterproofed. To do this, you need to lay sheets of roofing felt or film; the roofing felt is fastened together using bitumen mastic.
5. At the next stage of insulating the veranda floor, logs made of timber are installed. But before that, they should be soaked with an antiseptic. Insulation is laid between the beams.
6. After this, you can lay the boards on the floor.

Insulating the veranda from the inside

Isolation wooden room can be produced not only from the outside, but also from the inside. Insulating the veranda on both sides will help retain maximum heat in the room.

1. The technology for insulating a veranda from the inside begins with sealing all the cracks.
2. Next, you should make a frame from timber.
3. Afterwards, a waterproofing film is attached to the timber. It is more convenient and faster to install it from the inside using a stapler.
4. After this, a frame is made from metal profiles or timber and filled with foam plastic or similar insulation. It is better if the distance between the metal profiles is the same as the width of the insulation.
5. Drywall is mounted on top of the frame.
6. On last stage To insulate the veranda from the inside, the walls are puttied, painted or a decorative coating is installed.

Insulation of veranda windows

A lot of heat leaves the room through the windows. To eliminate this problem and properly insulate the veranda, you need to carefully consider the junction of these parts of the building. To begin with, it is worth replacing wooden windows with plastic ones.

PVC products protect heat in the house much better; in addition, they are excellent sound insulators. During installation, the joints between profiles and walls are foamed special means. To increase the effect, strip thermal insulation is used. But you shouldn’t save money and install single-glazed windows. Double or triple glazing will help insulate the veranda much better.

If, for some reason, there is no desire to change the windows, you need to insulate them by thoroughly examining the tightness of the wooden frames.

1. The first step is to check all the glazing beads. If they are loose or cracked, you need to remove the glass, clean the grooves and coat them with sealant. After this, the glass is put back, sealant is again applied along the edges and new wooden beads are installed.
2. Next, you should check the junction of the window opening and frame. To do this, use a regular metal ruler to go over all the joints. If there are places where it passes freely, it is necessary to putty them or seal them with polyurethane foam.

Door insulation is also carried out in a fairly simple way. It is lined with felt (or other similar insulation) inside and out. Some kind of decorative item made of film or other material that is not susceptible to weather elements, for example, leatherette.

Rubber seals must be placed around the perimeter of the wooden box. You should also check the junction of the door frame and the opening. If there are holes or poorly adhering finishing material, the old one is removed, cleaned and plastered or filled with foam.

Insulation of the veranda roof

A lot of heat leaves the house through the roof of the extension. If the roof is pitched and does not have an attic, you will not be able to move freely on it. To insulate the veranda with your own hands, you will have to disassemble the entire roofing material. Therefore, it is better to insulate such a roof during the construction stage.

Ceiling insulation

In order for the insulation of the veranda to be truly effective, the ceiling should also be insulated. Similar work considered quite difficult. The main thing is to choose the right technology and insulation. You can insulate the ceiling in two ways: along the “floor” of the attic or by tipping the ceiling in the extension.

Attic ceiling insulation is usually done when constructing a veranda. But this can be done over time. This option is considered the best for the reason that the height of the room is not “sneaked” and installation is carried out much faster. Foam plastic or other insulation is simply placed in the rafter frame and covered with film.

The technology for insulating a veranda from the inside is somewhat more complicated. But such thermal insulation of the ceiling can be done using several methods. On our website you can watch the process of insulating the ceiling on video.

Method one

1. First, a frame is made for the ceiling from 30*30 millimeter timber.
2. Insulation of the same thickness is placed in the space between the beams.
3. Next, the ceiling is sheathed with thin plasterboard.
4. At the last stage of insulating the veranda with your own hands, the ceiling is either plastered and painted or covered with siding.

Method two

1. The old ceiling covering is replaced with plywood or OSB.
2. Then the hydrobarrier film is attached.
3. Next, a frame is made from timber, into which foam plastic or other insulation is installed.
4. At the next stage, the timber structure is covered with film and lined with clapboard.

Method three

The simplest ceiling insulation technology is frameless. But only hard insulation is suitable for it. Foam boards are installed directly on the ceiling without additional structures. After this, the ceiling surface is covered with a special mesh and puttied.

Insulation of veranda walls

A lot of cold enters the veranda through the walls. Before insulating a cold veranda, you should think about insulating the walls. They can be used both from the inside and from the street.

External thermal insulation

If the walls are wooden:

1. First, you should seal all the cracks in the wooden veranda.
2. Next, a vertical frame is made of timber. The distance between the bars is about half a meter.
3. After this, insulation is inserted.
4. Then the waterproofing film is attached with a stapler.
5. On final stage covered with siding.

If the walls are block:

1. First they lay foam boards with special glue and reinforced with umbrella dowels.
2. Then the surface of the slabs should be coated with a special adhesive solution and a reinforcing mesh should be secured to them.
3. After the walls of the house have dried, they can be insulated with decorative plaster.

Insulating a house using the “warm seam” technology

A similar technology for insulating verandas is used for wooden structures. This method uses a tourniquet, tow, felt and sealant. Using this technology, a building can be insulated both from the inside and outside. Before work, the seam is cleaned of dirt, a tourniquet or tow is driven into it and sealed with sealant. Insulating a veranda in a wooden house with the “warm seam” technology allows you to significantly retain heat in the room.

Heating the veranda

The easiest way to solve the problem of heating and insulating a veranda during the cold season is a portable heater. To make full heating in the house you will need: project development, approval of the relevant authorities, complex work to carry out heating system etc. It is much easier to use something like the UFO and follow fire safety rules in a wooden veranda.

Insulating a veranda with your own hands: video

You can see how to properly insulate a veranda in this video.

If all insulation work is carried out technologically correctly and with high quality, the veranda will become a room that can be used all year round. Insulating a veranda requires time and material expenditure. But on the other hand, there will be additional living space where it will be pleasant to spend time not only in summer, but also in winter.

Frame extension to a wooden house

The construction of wooden houses is still popular among construction companies. Usually, there is a desire to build additional buildings for such houses that would emphasize the individuality of the building. A frame extension to a wooden house can, in principle, be erected independently, but for this you need to have construction skills and follow the rules and order of work.

To avoid any unpleasant surprises with the extension in the future, several issues need to be considered during its construction:

• Selecting material for the extension

The best option is a metal frame, then sheathed with wood. You also need to immediately think about what kind of wood (color) the veranda cladding will be made of, so that it matches the overall style of the house.

Basically, extensions are built after the construction of the entire house is completed, so it is necessary not only to build a foundation for the veranda, it is also desirable to ensure that both foundations are solid.

• Drawing up an extension project

You cannot start building a veranda without a design plan, as this can then not only spoil the external image of the entire house, but also affect the service life of the veranda. It is necessary to think over the layout, dismantle old buildings if necessary, provide a good approach to the construction site, think about insulating the veranda in a wooden house, etc.

Do-it-yourself insulation of the veranda of a wooden house

Since the veranda will be the place where noisy groups will gather, family conversations will take place during tea drinking, etc., it is necessary to think about how to ensure the preservation of heat inside the room during the cold season.

The first step in the process of insulating a veranda is choosing insulation. The most popular and popular types of insulation are polystyrene foam and mineral wool.

IMPORTANT: In order for the effect of insulation to be as noticeable as possible, a layer of penofol must be laid between the walls of the veranda and the insulation layer.

Since a frame extension to a wooden house usually has a plank floor, it must be insulated.

Warming the veranda floor

The floor must be puttied and painted with paint with frost-resistant additives. After painting, an underlay layer of penofol is laid on the floor, and a layer of insulating material is placed on top. Floor insulation can be made from natural materials (cork, granular insulation, cellulose) and artificial materials.

The floor can be insulated with bulk (expanded clay, slag, foam glass), sprayed (ECO wool, penoizol), self-leveling (polymer mixtures), rolled (mineral wool, linoleum) or tiled (foam glass, glass wool, gypsum fiber sheets) materials.

Since the floor in verandas is usually made of joists to which boards are attached, it is necessary to ensure that insulation is laid between the joists. To do this, you need to carefully remove the boards from the floor, lay out insulation between the joists, lay a vapor barrier layer, and then nail the boards back.

IMPORTANT: The insulation must adhere to the joists as tightly as possible. The height of the insulation should be several millimeters below the floor level. Such a gap will ensure air circulation so that moisture does not linger inside (this will protect the floor from the appearance of fungus and rotting).

Insulation of veranda walls

To insulate the walls of the veranda from the inside, you can use not ordinary insulation materials (foam plastic, mineral wool), but sheets of plasterboard. Their installation is very simple, it is fastened quickly, especially since its cost is low.

Since insulating a veranda in a wooden house with plasterboard sheets involves the construction of a sheathing, its basis can be not only metal, but also wooden frame. Insulation (foam plastic, glass wool) is placed between the sheathing, and the sheets of plasterboard themselves are attached using ordinary screws to the sheathing profiles.

If you insulate the veranda with only mineral wool, then it must be treated on top with penofol to ensure the required level of vapor barrier.

One more simple material PENOPLEX can be used to insulate the veranda. Such sheets are attached to the walls with glue. If you use PENOPLEX, then there is no need to carry out a vapor barrier, since the material already has good characteristics waterproof. A thin layer of plaster is then applied on top of the insulation, which is covered with wallpaper or simply painted in the desired color.

From the outside, the walls of the veranda are insulated in the same way: the sheathing is attached, the cavities between the sheathing profiles are filled with a moisture barrier and insulation, and then they are attached facing materials. A frame extension to a wooden house is usually built outside decorative panels or siding.

The veranda is a great place to spend an evening, weekend, meeting guests or Sunday breakfast. But almost everyone perceives the terrace only as an area intended for summer recreation. In winter, the room is blown by winds, here in best case scenario, store unnecessary things. If windows and good doors are not provided, then in December-February you will have to spend time removing snow, branches, fallen leaves, and debris. We will tell you how to insulate a veranda, what needs to be done so that the room can be used all year round, like an ordinary room or hallway. You will have to work on the foundation, roof, floor, walls, windows. But the result will please you when you relax with a cup of tea on a cold evening.

Foundation insulation

Ideally, the terraces were laid simultaneously with the main building. Then insulating the foundation will be less labor-intensive, and you won’t have to spend a lot of time and effort. If the room is built later and heating is not provided, then 20 percent or more of the heat will escape through the concrete. To keep heat loss to a minimum, you will have to work on insulation. Depending on personal preferences, you can choose either polystyrene foam, mineral wool, or jute mats.

To ensure high-quality insulation of the terrace foundation, it will have to be dug to a depth of 1 meter. Next, sheets of foam or mineral wool are laid and attached to the base special glue, self-tapping screws or special anchor bolts. An adhesive base is more preferable, since you will have to drill holes for fasteners, and these are additional cold bridges.

All seams are sealed with sealant or foam. The surface is waterproofed with roofing felt or a special film, then a reinforcing mesh is installed, followed by plastering.

Alternatively, the plaster can be replaced with clinker or finishing bricks, siding, or porcelain stoneware. Important: all materials must be intended for outdoor use. Otherwise, the insulation procedure will soon have to be repeated.

After this, you can bury the foundation back. Important: it is not recommended to carry out work simultaneously along the entire perimeter; you will have to insulate it in parts. If a shallow-depth area was installed under the veranda or terrace strip foundation, then dig at least to a depth of 30-40 cm. But it is impractical to carry out insulation work only above the surface of the earth.

Floor insulation

Just insulating the foundation of a private wooden house is not enough. It is important to equip the floor appropriately so as not to freeze in winter and not pay astronomical heating bills. Among the most relevant methods for eliminating cold bridges, we highlight:

• bulk type insulation. The space under the joists, rough and finishing floors is densely filled with expanded clay or slag waste. Ideally, the operation is carried out at the construction stage, after laying the foundation. If it is possible to disassemble the floor boards and remove other coverings, then this option is also suitable for a used veranda or terrace;
• raised floor Its arrangement is determined by the level of the existing floor. It is important to understand that the level of the floorboards will rise significantly. Calculate it so that the additional coating does not interfere with opening the doors. Additional joists are placed on the existing floor, the gaps between which are filled with foam plastic or other insulation. The entire space is covered with a waterproofing film, and a finished floor is laid from a floor lath or tongue-and-groove deck board;
• installation of heated floors. If you are planning to transform your terrace with your own hands from a household extension to a wooden or stone house into a living space suitable for winter living, this option will be ideal. Ideally, it is better to provide for it at the stage of pouring the foundation, since a solid, level base is required - for example, a concrete screed. During operation, no deformations, tears, or cracks should occur; for this, the screed must dry.

To prevent condensation from accumulating from the temperature difference between the concrete and the floorboard, vents are made before laying the electrical wire. Otherwise, failure of the coating and costly alterations are inevitable. And on the veranda the air will be constantly humid, which is harmful to health.

An important disadvantage: increased energy consumption. But if it is not possible to install heating radiators, the option with heated floors should be considered more carefully.

How to insulate the walls on the veranda

Mandatory stage. Without this, all other work will be meaningless. The area of ​​the walls exceeds the combined area of ​​the floor and ceiling. You can spend tens of thousands on re-equipping the foundation and installing heated floors, and hot air will escape into the atmosphere through thin partitions.

You can insulate a veranda or terrace both from the outside and from the inside. The choice of option depends on many factors:

• availability exterior finishing, for example, a ventilated facade;
• wall material. The frame structure can be insulated in any way, where it is possible to remove the cladding.

External insulation can be combined with work on the foundation of the terrace, using the same polystyrene foam or mineral wool.

Stages of work

• leveling surfaces. Brick walls are cleaned of dust, cracks and chips are repaired, and protrusions are cleaned. If the wall is wooden, it is necessary to caulk all the cracks and remove knots. Large masonry defects are treated with sealant or foam. After hardening, everything is thoroughly cleaned to obtain a smooth surface. Excess foam is cut off with a regular knife;
• installation of the sheathing in increments equal to the width of the insulation;
• laying sheets of foam plastic or mineral wool, fastening with adhesive or special dowels. Beads are placed on top of the insulation as an additional fastening element. In cold climates, it is recommended to lay insulation in two layers with the obligatory overlap of joints by 10-20 cm;
• laying a waterproofing film or membrane. If this is not done, condensation will accumulate;
• performing finishing works using siding, lining, ventilated porcelain stoneware facade and other materials. Ensure that the decoration of the veranda matches the main building, so that there is no disharmony or imbalance.

Insulation of walls from the inside is carried out using the same technology with one condition: the waterproofing is not laid on top of the insulation, but under it. Finishing is done either with siding, or plasterboard or clapboard with appropriate fire retardant treatment. Wooden sheathing It is recommended to replace it with aluminum. Then you can plaster, wallpaper, or decorate the interior in another way.

Ceiling insulation

From school physics courses we know that warm air rises. And if there are no obstacles on the way, it will safely go into the atmosphere, and you will complain that the heater’s power is not enough and it’s cold on the terrace. To prevent this from happening, the stage of finalizing the ceiling should not be postponed until later.

Sequence of work:

• Installation of sheathing. If there are beams, then insulation sheets are laid between them. If the ceiling is concrete, then you can’t do without lathing. Important: there must be an air gap and a layer of waterproofing membrane between the foam or mineral wool and the base to prevent condensation from forming.
• Traditional insulation materials can be replaced with polymers coated thin layer aluminum foil, reflecting heat into the room. For most rooms this is enough to reduce heating costs.

Insulation of window and door openings

A draft is a rather unpleasant thing. You can carefully work on the ceiling, but if it blows from under the window sill, all the work will be in vain. It is necessary to eliminate all cold bridges that arise in window and door openings.

Experts advise taking the easiest path: replacing outdated blocks with modern metal-plastic ones. But this option requires significant expenses, which is impractical when insulating a country veranda.

You can avoid unnecessary costs by replacing glazing beads, filling the cracks in log walls or at the junctions.

Be sure to apply sealant around the perimeter of the glass, under window sills and ebbs. Old platbands and slopes that have served their useful life can be replaced with new ones with the obligatory preliminary treatment of all cracks with polyurethane foam.

The door block can be completely replaced or the existing door can be covered with leatherette, laying a layer of foam rubber. If this is not enough, you can purchase and install a heat gun or curtain, and then a stream of hot air will greet you at the entrance. But this option requires significant expenses both for the purchase of equipment and for paying electricity bills.

Insulating the veranda using heating

If all the necessary work has been carried out, but the veranda is still not very comfortable, think about options for installing heating equipment:

• water heating. If the house has individual or centralized heating, the pipes can be extended to the terrace and installed standard radiators heating taking into account the area and wall material. If you do not plan to use the veranda constantly, taps are installed in front of the radiators to regulate the flow of hot water. This will help reduce gas or electricity consumption;
• heaters, electric stoves, IR emitters. The option is acceptable if the veranda is used from time to time. Constantly maintaining a comfortable temperature will be too expensive;
• gas boilers. Installation of a separate heating device only for a veranda or terrace is impractical for many reasons. This includes the need to obtain the appropriate permit, the high cost of equipment, and the constant order of liquefied gas cylinders;
• wood stove or fireplace. The options are good for stone buildings. On a veranda or terrace made of logs or in a frame building, they can cause a fire. If it is possible to equip a high-quality chimney and ensure fire safety, then evenings by the smoldering fireplace will soon become your favorite habit.

insulation of a cold extension to turn it into a living room in a summer house

When building verandas, they rarely think about heating them. The extension to the house is used more in the warm season. To change the situation, it is most effective to insulate the veranda. And this can be done with my own hands. If you don’t know how to insulate a veranda, this article will help you understand the important nuances.

Suitable materials

There are a variety of insulation resources on sale. We present both products that have been proven for decades, as well as new ones, which also provide reliable protection of the room from the cold. Which specific insulation to choose depends on the budget, features of the terrace, design, etc.

The insulation of the room must be based on a natural composition, resistant to fire, mechanical stress and the environment. In most cases they use:

• Styrofoam;
• penofol;
• expanded polystyrene;
• basalt, mineral wool;
• expanded clay;
• OSB boards;
• block house.

Very often, mineral wool is used for insulation. It is resistant to fire, has low thermal conductivity, and is not afraid of deformation. The material provides good noise protection and is quite durable. At the same time, mineral wool is inexpensive, and the installation of the material can be carried out by a user even with minimal construction skills. One of the disadvantages of mineral wool is its short working life. The basalt analogue has approximately the same performance indicators, but it is more natural in composition.

Expanded polystyrene is also used for insulation. Durable and easy to use material available at a reasonable price. It perfectly protects the room from heat loss. The main disadvantage of polystyrene foam is its high flammability. Upon contact with fire, hazardous toxic substances are released.

Classics of the genre - polystyrene foam. The material is chosen for its durability, low vapor permeability and hygroscopicity. There is no need to additionally install hydrofilm on it. The material is universal and easy to install. But it quickly ignites and attracts the attention of rodents. Foam plastic is installed using different methods, the main thing is to do it correctly.

Penofol is used in combination with other insulation materials or independently. It has low vapor permeability and is environmentally friendly. Penofol is non-flammable. This is a modern and effective material that is perfect for insulating extensions in a private house or country house.

You can also consider expanded clay. Fired clay material is presented in the form of porous granules. It is used only for insulating ceilings and floors.

In this video, a specialist will tell you how to attach a veranda to your house with your own hands.

Thermal insulation technology

Without having outstanding construction skills, you can make a warm residential veranda. This will allow you to stay indoors comfortably during the winter period. You just need to stick to proven technology.

Thermal insulation of terraces is carried out from the inside and outside. External insulation has the following advantages:

• garbage remains on the street, since the main work is carried out outside the room;
• no need to move during repairs;
• the area of ​​the terrace remains the same;
• The finished walls retain heat well and do not become damp.

The situation is different when internal thermal insulation. You can perform it in any weather conditions since you are indoors. Bases are freely accessible at any height. But on the other hand, you need to prepare for construction, leave the room for a certain time. To better sheathe the structure, it is necessary to dismantle the old coverings.

Regardless of the insulation method, you will need a set of tools. Typically used:

• stapler;
• construction knife;
• roller;
• hacksaw;
• tassels;
• screwdriver

In addition to the main material, you need to purchase polyurethane foam, special film, and fastening components. When the work process comes to an end, it’s time to start finishing the interior.

Floor

To insulate the floor covering, we need expanded clay or crushed stone. We fill the floor with them, add a layer of sand on top, and tamp it down. Next you need to design the reinforcement mesh. Follow the dimensions specified in the insulation project. All that remains is to fill the top with concrete solution. Once the floor is dry, you need to install waterproofing; roofing felt is often used for this. You can put wooden logs on top of it, which are best treated with protective agents beforehand. There will be a thermal insulation layer between the joists. When the floor on the veranda is installed, the finishing coating needs to be laid.

Do not forget that before insulation the old material must be removed.

If you divide the process into stages:

1. The floor covering was removed. We install jumpers between the open joists. The floor will be divided into cells; we fill them with insulation.
2. Use polystyrene foam or mineral wool as the main resource. The material must be cut correctly so that it matches the size of the cells. Make sure there are no gaps at the joints of the pieces.
3. If you use mineral wool, the bottom needs waterproofing. So the loose material will not draw moisture from the ground. There will be a vapor barrier on top of the thermal insulation.
4. Soft mineral wool is great for filling voids. If you use polystyrene foam, gaps may appear. You can eliminate them using polyurethane foam.
5. Regardless of what kind of insulation you have at your disposal, its thickness should be less than the height of the logs.

When the flooring is ready, a gap will appear - ventilation. Free access to cold air will prevent the accumulation of dampness under the floors. This will extend the life of the wooden components.

From the basement

There are cases when the veranda is equipped with a basement. In this case, it is easier to insulate the floor, since there is no need to dismantle the old flooring.

Algorithm of actions:

1. On beam floors and back side flooring, using a stapler or mounting adhesive, attach the vapor barrier layer.
2. If the distance between the beams is significantly higher than the width of the insulation slab, the side faces are supplemented with slats and bars.
3. Installation of thermal insulation.
4. Vapor barrier laying.
5. Installation of a rough ceiling.

It would be useful to perform decorative finishing.

Roof

Roof insulation depends on the characteristics of the roof. If it is pitched and there is no attic, you will not be able to move around it on your own. That is why it is better to insulate the coating at the construction stage or from the ceiling. Let's look into the nuances further.

Ceiling

Most of the heat escapes through the roof. It is not recommended to skimp on insulation in this area. All work will be carried out from the inside, since ceiling insulation from the outside is only possible during the direct construction of the building.

In order:

1. We remove the old coating and apply a waterproofing film.
2. The insulation on the ceiling is mounted on a frame made of wooden or iron slats.
3. The thermal insulation material must be covered with a film that will protect against steam.
4. The top of the structure is covered with plasterboard.

This makes the height of the room smaller. If this option does not suit you, insulate it from the inside using vacuum panels. Their installation does not require a frame, so the space of the room will remain the same.

In general, the method of insulating the ceiling is almost identical to the walls. The only inconvenience: working on weight. In this case, you won’t be able to cope without an extra pair of hands.

Walls

We recommend treating the outside wall surface with polyurethane foam, polystyrene foam or mineral wool slabs. Subsequently, the coating can be decorated with almost any finishing material. The end result will be functional and beautiful.

Installation of insulation on concrete or brick walls is carried out according to the following algorithm:

1. We create and install a frame made of metal or wood. For this, slats and bars or a galvanized profile are suitable.
2. Treat the timber with an antiseptic in advance, which will protect it from rotting.
3. We fasten the frame using self-tapping screws, a hammer drill and a screwdriver.
4. We install the selected insulation. Usually glue is used for this.
5. On installed material We attach the reinforcing mesh.
6. We paint, plaster the panels or install the selected cladding.

If you do everything correctly, using high-quality material, in winter the terrace will be reliably protected from the cold. You can decorate the room as a hallway or arrange a compact winter Garden.

When insulating you will need building level. Make sure that no cracks or gaps appear on the frame. Install the insulation in a single layer, eliminating excess parts.

The process of insulating wooden walls is different. The slats are first installed on the original surface. The insulation is mounted to them using dowel umbrellas. The structure is covered with a waterproofing film. To fix it, staples are used. To protect the thermal insulation layer from moisture, use metallized tape.

If high-quality insulation is a priority, and you consider the terrace as a living room, you will definitely need thermal insulation of windows and doors.

Windows and doors

Can be used for insulation different materials. A modern and optimal option is PVC double-glazed windows. But there are common cases when it is necessary to insulate wooden frames.

First of all, preparation: seal the windows and doors. This step is not necessary if double-glazed windows are installed on the veranda. If we work with ordinary windows, we need to process the glass panels and the joints between the frames. Sticks energy saving film. Adhesive tape is applied along the edge of the glass sheet, and on top - protective film. We seal the joints of the frames with a solution of chalk and gypsum. Add a little water to the dry mixture and stir until it thickens. Apply the resulting composition with a spatula.

Now let's move on to the doors. The main thing is to seal the joints so that cold air does not enter the room. We take the batting, remove the structure from the hinges and stuff the protruding rollers on top and bottom. Then we beat it tightly and secure it with a stapler or nails.

We still recommend using double or triple glazing. They retain heat well and provide good sound insulation. Make sure that the connection points between windows and walls are sealed with glue or foam.

"Warm seam"

Using modern techniques, it will be possible to reliably insulate the room. The “warm seam” technology is widely popular, but it is only relevant for wooden buildings.

We will need:

• tourniquet;
• tow;
• felt;
• sealant.

Insulation can be done both inside and outside. Before work, remove dirt from the seam, hammer a tourniquet or tow into it, and seal it with sealant. The “warm seam” technology is actively used, since with its help it is possible to retain a significant amount of heat.

Additional heating

The main way to maintain comfortable conditions in a room is to insulate it. Various equipment and technologies can be used as additional measures:

1. Fireplace, stove. The best option if you don’t want to lay pipes or set up electrics. Plus - it's economical. You just need to constantly monitor the heat. To prevent fires, you need to additionally protect the floor and walls.
2. Heaters. Devices for every taste are available for sale. They are placed on the floor and hung. For a veranda, 1-2 devices will be enough, depending on the area. The equipment is easy to use and easy to configure.
3. Climate control. Complex systems not only keep the terrace warm, but can also cool the air. Climate control cannot be considered as a full-fledged source of heating.

The best combination is an insulated room and an additional heating source. You can create comfortable living conditions yourself by installing thermal insulation on the veranda.

The issue of thermal insulation of the veranda becomes relevant when there is a desire to use this room all year round. Verandas are usually unheated, as a result of which the temperature in them can drop below zero in winter.

If you want to provide comfortable temperature air inside the veranda even in the coldest season, you need to take care high-quality insulation extensions.

With comprehensive thermal insulation using proven materials, and installation of a basic heating device: a small solid fuel stove, or a good electric radiator, it is possible to ensure constant temperature in the veranda at +18+19 degrees.

1 Carrying out work from the inside

It’s worth mentioning right away that since the construction of a veranda is, as a rule, a budget project, as a result of which it is built from inexpensive materials - wood, cinder blocks, or gas silicate blocks, the veranda will have to be insulated comprehensively.

You can, of course, only insulate the walls and even insulate the ceiling, but you will not get the desired effect from such thermal insulation.

To turn a veranda into a full-fledged year-round living space, it is necessary to insulate both the surface of the walls from the outside and the ceiling, walls and floor from the inside of the building.

1.1 What is the best way to insulate?

If savings are at the forefront of the insulation project, then you can use regular foam. This material has good thermal conductivity and is inexpensive.

Also, polystyrene foam is easy to work with, even one person can handle it without any problems, so if you plan to do everything yourself, polystyrene foam - a good option from inexpensive insulation materials.

The thermal conductivity of polystyrene foam is approximately 0.04 W/mK per , which is, of course, less than that of mineral wool or extruded polystyrene foam, but also quite good, considering the cost of this material.

To insulate walls, ceilings and floors, you can take foam plastic 5 centimeters thick - in most cases it will be quite enough.

Expanded polystyrene benefits not only in its thermal insulation properties. An important fact is that this material has minimal vapor permeability and hydrophobicity, as a result of which condensation will not form on its surface, which is the main enemy of most insulation.

The advantages of polystyrene foam also include ease of installation - this insulation is made in the form of slabs measuring 100*160 cm, for installation of which in most cases only an adhesive solution is sufficient.

2.1 Do-it-yourself veranda insulation technology (video)

If you have a veranda, then we can say that you happy man. This is a great place to spend time in the summer. For each owner, the veranda serves a specific purpose that he pursues. This additional area home, which can be used for any purpose. Only in winter the veranda can play a cruel joke on you. The whole house can lose heat because of it. And it will be simply unrealistic to be in the veranda itself. To make your stay in the house and on the veranda comfortable, we recommend that you insulate your veranda.

However, it's easier said than done. From this article you will learn how to insulate a veranda in a wooden or brick house. What materials to use when working? Should you insulate from the outside or from the inside? We will look at all this further.

Which method of insulating the veranda to choose

There are many disputes regarding the type of insulation of a veranda or terrace. Some say that it is better to do the insulation of the veranda from the inside with your own hands, while others are supporters of the method of insulation from the outside. But which one is better? We will shed some light on this mystery by comparing the advantages and disadvantages of both methods.

Let's start with insulating the veranda inside. Here are the advantages of this method:

1. Work is carried out at any time of the year and in any weather.
2. You can have free access to the surface at any height.
3. At one time you can insulate every surface - the floor, all walls and ceiling.

True, this method of insulation also has its disadvantages:

• it is necessary to dismantle the finished coating;
• with this option, the freezing point begins to shift into the wall, which is fraught with its gradual destruction;
• a layer of insulation can take away precious space inside;
• During operation, debris accumulates inside;
• Some materials may contain harmful substances, so you will have to stick only to environmentally friendly ones.

This was a comparison of insulation from the inside. What can we say about the external method? The advantages are as follows:

1. During operation, debris will not accumulate in the room.
2. The space inside does not become smaller.
3. Repair work can be done without disturbing your lifestyle. No one will have to move anywhere.
4. The freezing point shifts into the insulation, so the walls will accumulate heat and not collapse so quickly.
5. After insulation, the outside veranda can be decorated and transformed by covering it with clapboard, siding, decorative bricks or other facing material.
6. You can choose any material, regardless of its components. He will still be exactly outside.

As for the disadvantages of insulating the veranda from the outside, there are several of them:

• work can only be carried out in good weather;
• It's difficult to access every surface, especially the roof.

We have provided you with some statistics, and you can decide for yourself which insulation option to choose. Analyze the pros and cons and consider your circumstances. When you have chosen a method of insulation, you can think about thermal insulation material.

Insulation of the veranda - list of materials

Nowadays there are so many insulation materials that it is sometimes difficult to make a choice. All of them are good in their field and are used by builders. Nevertheless, over some time, each material has received a certain reputation, so you can make a list of the best materials for insulation. Let's take a look at it as it was compiled based on user reviews, features, and pros and cons.

Styrofoam

This material is known to everyone. It does its job perfectly and has many advantages. The material is produced in rigid slabs of a certain thickness. The greater the thickness of the foam, the better the thermal insulation of the veranda.

Advantages of the material:

1. Low price and availability.
2. Versatile, suitable for insulating ceilings, walls and floors.
3. The material is very easy to work with.
4. Possesses high degree heat saving.
5. Not afraid of moisture.
6. It is light in weight and does not weigh down the structure of the veranda.
7. Non-toxic and able to absorb noise from the street.

Note! You can also use polystyrene foam. Its properties are very similar to polystyrene foam, only even better. The material is durable and well processed.

Penofol

Practical material that is easy to work with. Due to the foil layer, the material additionally protects the wooden veranda from the cold.

Advantages of the material:

1. It can be combined with other materials, used as one insulation material or reinforced with others.
2. It is environmentally friendly, will not emit toxic and harmful substances. Therefore, you can use it inside.
3. It’s very easy to work with; anyone can do the insulation process.
4. It is fireproof.
5. Penofol will protect the veranda from cold air from the street.

Mineral wool

No less popular insulation than polystyrene foam. Can be used as rolls or slabs. Mineral wool has earned the respect of many builders and is used very often in insulating verandas. It's all about its characteristics and advantages:

1. The material is vapor permeable, i.e. it is breathable. Thanks to this, the veranda will have an excellent microclimate and optimal humidity.
2. This is an environmentally friendly product that will not cause any harm to anyone.
3. The quality of insulation of mineral wool is excellent.
4. The material is lightweight and easy to work with.
5. Just like polystyrene foam, cotton wool has the ability to soundproof a room. No extraneous sounds will penetrate into the veranda.
6. Versatility. You can insulate the floor, walls and ceiling of the veranda with cotton wool.

Important! One type of mineral wool is basalt wool. The material is biologically stable, does not burn, resists moisture and is durable.

PPU (polyurethane foam)

An excellent material for insulation, which is applied by spraying. It can be compared to polyurethane foam, which increases several times after application. Although, on sale you can find ready-made panels that are mounted according to the foam plastic principle. However, this method is worse than the spraying method. Why? When fixing slabs (this applies to foam plastic, mineral wool and other slabs and roll insulation) cold bridges are formed, through which the cold penetrates inside the veranda. And when sprayed, a monolithic layer without cracks is created.

Advantages of the material:

1. No cracks.
2. High quality thermal insulation.
3. Polyurethane foam is not afraid of moisture.
4. It is biostable.
5. It is lightweight and has soundproofing qualities.
6. Penetrates into all cracks, creating a monolithic layer.

Advice! With all this, polyurethane foam is quite expensive, and to apply it you need to have special equipment. In addition, the material is vapor-proof.

It is from this list of materials that you can choose the insulation that you like the most. With it, your veranda will be reliably insulated. Based on the characteristics of the material, as well as your financial capabilities. If you have already chosen, then you can proceed to the insulation itself.

We insulate the foundation of the veranda

High-quality insulation comes down to eliminating heat loss through each structure. After all, the task of insulation is not only to prevent the penetration of cold. The main task is to conserve the heat generated by the heating system of the room. It is noteworthy that the veranda is most often built on the same foundation as the entire house. Most often, the base is monolithic concrete or slabs. They are the bridge of cold through which approximately 20% of the heat escapes. Therefore, you first need to take care of insulating the foundation and basement.

The ideal material for this job is foam. It is cheap, lightweight and has good resistance to external influences. Insulating the veranda with polystyrene foam is one of the most common options. So, what do you need to do to insulate the foundation:

1. Dig it to the ground. If it is not waterproofed, then lubricate it bitumen mastic. So, you will extend the life of the concrete and foam itself.
2. Then you need to install the foam boards on the gravel bed and glue them to the foundation. Use polyurethane glue.
3. Apply glue to the joints formed between the plates.

That's it, job done. The entire foundation needs to be protected, right down to the base. And the foam itself can be lined with any material.

We insulate the floor in the veranda

The floor is another source of heat loss in verandas and terraces. Most often, the floors in the veranda are made of concrete screed. Sometimes wood is used (by the way, it is warmer). If you are planning to install a heated floor in your veranda, we recommend that you opt for an electric heating system in order to turn on the system as needed. As for water insulation, it is better to avoid it on the veranda. During frosty weather, pipes may freeze and become deformed. Then the system will need to be replaced completely. How to make a warm floor on the veranda is shown in this video.

But what if you don’t want to use heated floor technology? You can insulate the floor on the veranda in a simple way “along the logs”. Here's what you'll need for this:

1. Make a subfloor from planks.
2. Install logs on the boards. The height is selected taking into account the thickness of the future insulation.
3. The logs and the space in them are covered with a waterproofing film, extending onto the walls.
4. Now you can install insulation between the joists. It is best to use mineral wool. It needs to be placed tightly in the free space so that there are no large gaps.
5. The insulation layer is covered with a vapor barrier film, overlapping the walls.
6. The finished floor is installed on top. you can use OSB boards, plywood or boards. You can lay laminate or other flooring on top.

We insulate the walls of the veranda

A lot of heat escapes through the walls. This is why insulating the veranda walls is so important. You can insulate walls from the inside with polystyrene foam, polyurethane foam or mineral wool. You decide. However, the insulation technology is almost identical. Your task is to create a sheathing so that this or that material can be laid in it. In fact, the work is reminiscent of floor insulation, only in a vertical plane.

When the veranda is made of wood, insulation occurs as follows:

Note! External insulation is performed in the same way. Only the finishing material should not be afraid of moisture and external influences. It could be facade paint or plaster, bark beetle, siding.

If the veranda has concrete walls, then you can insulate it with polystyrene foam. Everything is a little simpler here. You need to glue the foam boards to the wall using special glue, and then strengthen the fixation with dowels with an umbrella. Next, the surface of the slabs is coated with an adhesive solution into which the reinforcing mesh is embedded. After drying, you can do decorative plaster (bark beetle, fur coat, etc.).

We insulate veranda windows and doors

Windows are almost the main source of heat loss. If they are old and have cracks, then the heat will successfully leave the room. To eliminate the problem, you can blow out all the cracks and holes with foam. But sometimes this method simply does not help. The fact is that the windows can be very old. In this case, we recommend that you replace them with new ones made of metal-plastic. As you know, they perfectly retain heat in a room without letting in the cold.

Among other things, such windows will isolate the veranda from noise. Installation plastic windows it is not a simple matter, however, the companies that sell them provide such services. You can use them, saving energy, time and nerves. And professionals will not make installation errors that could be fatal.

As for the doors, they need to be upholstered with felt or other insulation from the inside and outside. Rubber seals can be installed on a wooden box. Inspect the places where the door frame connects to the opening. If you find cracks and holes, fill them with foam.

We insulate the ceiling of the veranda

At the end of the entire complex of insulating the room, it remains to take care of the ceiling. This is not a job that is easy for them, since the work is carried out at heights. Still, if you choose the right technology and insulation material, then everything will work out.

There are two options for ceiling insulation:

The first option is most often done during the construction stage. Although, nothing prevents you from doing it later. Its advantage is that the ceiling does not lose its height and the room does not become smaller. The work is simple: you just need to lay the insulating material in the rafter frame and sew everything up with film.

When it comes to insulation from the inside, it has its own difficulties. There are 3 different options for insulating the ceiling from the inside:

1. First of all, a timber frame with a cross-section of 30×30 mm is mounted on the ceiling. Insulation of identical thickness is placed in the resulting space. It is advisable to work with dense insulation materials such as polystyrene foam. Then you need to sheathe the ceiling with sheets of plasterboard and finish it.
2. The ceiling covering is replaced with OSB boards or plywood. Then the waterproofing film is fixed and the timber frame is filled. The insulation is installed according to the already familiar principle. All that remains is to cover everything with film and line the ceiling with clapboard.
3. The third method is frameless. It can only be realized with rigid insulation, such as polystyrene foam. Plates of material are laid on the ceiling using glue and dowels and the ceiling is covered with a special mesh. The surface is puttied and the ceiling is finished as desired.

That's all, now your veranda is completely insulated from the cold and can withstand any frost. It is clear that this requires spending a lot of money, effort, time and nerves, but the result is worth it.

Let's sum it up

So, you have learned exactly how you can insulate your veranda by insulating the foundation, ceiling, walls, floor, windows and doors. All you have to do is follow the advice, purchase the material and put everything you’ve learned into practice. As for heating the veranda, the ideal option is a mobile heater that can be carried. This is either an electric radiator, oil radiator, fan or UFO. It’s just important to follow all safety rules. Then your veranda will be warm whole year. You can relax in it, make a winter garden or use it for other purposes.
