Insulating the veranda from the inside with your own hands. How to insulate a veranda yourself: increasing the frost resistance of a summer structure How to insulate a wooden extension to a house

Insulation of the veranda can be done at any time of the year. There are two options: insulate the building from the outside or from the inside. The first method should preferably be performed only in good weather - it will be easier to work with, and the materials used will not be damaged. But the second one is quite relevant in cool and even cold weather. In addition, you can kill two birds with one stone: insulate the veranda and prepare a good base for interior decoration.

If you have not yet managed to insulate the veranda, now is the time to correct the situation. Insulation work will provide an excellent opportunity to gather with family and friends in winter country house over a cup of warm cocoa. What and how should be done to insulate the veranda from the inside - useful information you will find in our material.

1. Select the material

First of all, estimate the total amount of work and the required costs. Take measurements of the floor, walls and ceiling of your veranda. Now is the time to decide on the insulation material. There are several options here: foam, mineral wool, polystyrene foam, polyurethane foam. The most popular are the first two: with their help you can translate cold veranda to “warm” status and save family budget. Keep in mind that foam sheets are usually quite thick - up to 12 cm. This feature will reduce the usable area of the room. Mineral wool will retain heat better and is much easier to install. In combination with double-sided metallization or with an outer layer of foil, you will get maximum warmth on the veranda, but you will also be provided with significant financial costs.

Tip from InMyRoom: if your veranda is too large in area and you want to stay warm even in severe frosts, you should consider the option of combined insulation. To do this, it is necessary to install rolled thermal insulation based on mineral wool on the walls, and then sheet foam.

2. Tool preparation

The most reliable method of insulation is considered to be frame. This design will be strong and reliable, in comparison with the usual gluing of insulating material to required surface. In addition, the frame will allow you to lay any type of insulation on the walls and hide it under any sheathing - no matter what you choose, drywall or lining, everything will look aesthetically pleasing. To install thermal insulation you will need various tools. The insulation you have chosen, wooden blocks and slats of various sections, a hacksaw, a screwdriver, self-tapping screws, nails, a level, a tape measure, a pencil, a construction stapler with staples, polyurethane foam, a roller, a protective antiseptic and a moisture-resistant film - here is a set of tools with which you can perform all the necessary manipulations for insulation verandas.

Tip from InMyRoom: The size of the timber should depend on the number of layers of material used and its thickness. If only one layer is intended, then make a wooden beam 50x50 mm - after all, the insulation itself is 50 mm thick.

3. Wall insulation

The first priority is to make a frame on the walls: place wooden blocks in a horizontal position over the entire plane with an interval of 50 cm. The size of the beam depends on the number of layers of insulation and its thickness. The first beam can be laid directly under the ceiling. Then use a tape measure to measure the required space from the bottom edge of the beam (about 50 cm) and mark with a pencil the place for the next beam. On the marked lines, screw the frame elements using a screwdriver and self-tapping screws - we do this until the very end. Don't forget to use a level for all these manipulations.

As soon as the wooden frame is made, you can safely begin the insulation process itself. Insert the cut sheets of polystyrene foam into the resulting openings and glue them along the ends. Thermal insulation in rolls is nailed (or sewn) to the slats, and the excess is cut off. Keep in mind that mineral wool must be inserted tightly with a slight spacer between the frame. Make sure there are no holes or cracks. To insulate the walls of the veranda, all that remains is to attach a vapor barrier - it will not allow dampness to penetrate into your family nest. We do this work with an overlap, with a margin of 10 cm. To attach the material, use a stapler and staples: attach protective layer it will be easy to get to the frame. And finally, seal all joints with special tape.

Tip from InMyRoom: To ensure that the wooden frame for insulation lasts for many years, treat it with an antiseptic - it will protect the wood from mold and rotting.

4. We insulate windows and doors

Often the veranda has a large part of the glazing - therefore, the issue of timely insulation is on the agenda. The main heat loss occurs through windows and doors. Pay attention to the already installed windows: what quality they are, how long they have been in use and whether they retain heat well. If the results do not please you at all, the first thing to do is replace the windows. Bet on doubles or triple glazing– and save heat, and the sound insulation will be much better. Make sure that the joints between the window beams and the walls are well treated with mounting adhesive or foam. Insulating doors is an equally important task. Alternatively, line it with felt (or other similar material) either outside or inside. Place around the perimeter door frame self-adhesive rubber seals. If possible, you can install a second door - you will get an additional air gap.

Tip from InMyRoom: Don’t forget that so-called “cold bridges” often appear under window sills. To eliminate a gaping crack, use the same sealant - the thermal resistance will increase several times.

5. Floor insulation

The easiest way is to lay the insulating layer directly on the floor. Main condition - mechanical strength basics. If you choose this option, then first you will have to cover up all the cracks in the floor epoxy resin. As a result, you will get a “silent”, almost monolithic floor. As soon as the base is prepared, begin laying the roll moisture-resistant insulation. Using a stapler and staples, shoot the material to the floor in increments of 10–15 cm. Make it a rule: the thicker your thermal insulation material, the more often the fasteners must be made. We nail the laid insulation layer in the corners with nails with wide heads. All that remains is to tape the seams, and the heated floor is ready. Finally, lay chipboard sheets and any finishing coating you like (carpet, linoleum) on top.

Tip from InMyRoom: the direction of the insulating layer should be perpendicular to the finishing coating - this feature must be thought out in advance so that the floor on your veranda will last a long time.

6. Ceiling insulation

After insulating the floor and walls of the veranda, you can move on to the final stage: insulate the upper part of the room. Since any ceiling is exposed to precipitation, good waterproofing work will be required. First, remove the headliner. Then the waterproofing layer must be installed. A special film with perforation is quite suitable for this. Using a special metallic adhesive, seal all seams of the film. All other work is similar wall installation on insulation.

Tip from InMyRoom: performing installation wooden frame and installing ceiling insulation, be sure to use safety glasses - there is a risk of eye injury when small chips fall off or when attaching insulation with staples and nails.

Tips from a professional: nuances of veranda insulation that are important to know about

We learned from architect Nikita Morozov what subtleties you need to remember when insulating a cold veranda, what you can save on and how to achieve more effective result.

Nikita Morozov is an architect. In 2007, he organized the design bureau KM STUDIO, in which young architects and designers create interiors in different styles- from art deco to loft. In her work she appreciates the opportunity to constantly meet new people interesting people, draws inspiration from books and cinema, classical fine arts and the latest technologies. He believes that an ideal interior should combine aesthetics and ergonomics and give impressions.

Features of the extension

When choosing a veranda insulation material, consider which room the veranda will be adjacent to. If this is a kitchen or fireplace room, then you should refuse to use some materials for reasons fire safety. For example, it cannot be said that polystyrene foam is a rapidly flammable material, but when high temperature it melts, releasing toxic smoke.

About materials

To the above recommended materials, I will add Penofol as an additional or main insulation. Penofol consists of foamed polyethylene and a layer of strong aluminum foil: it reflects well ultraviolet radiation, and practically does not burn, and retains heat at very low temperatures. A good analogue mineral wool – basalt wool. In terms of characteristics, it is absolutely identical to mineral, but is an environmentally friendly material.

About insulation from the outside

For a more effective result, I also recommend insulating the external walls of the veranda. Use foam and mushroom fastenings. Before insulation, saturate the wall with anti-fungus and mold repellents. After the insulation boards are fixed, secure the mesh on top of which you can apply the finishing coat. There are many more ways to insulate walls from the outside - the choice of one method or another depends on the finishing material, budget, and climatic conditions at the time of the insulation process. External wall insulation has a number of advantages over internal wall insulation. For example, with internal insulation, the freezing point moves into the wall, which leads to its destruction; for external use - insulation, which reduces the rate of destruction of walls, and the latter can accumulate heat. The internal area of the veranda is also preserved and there is no need to dismantle the finishing.

What to do with windows

The quality of window installation and their condition certainly affects the coefficient of heat loss in the room, but if the budget does not include a relatively costly replacement of windows, then a number of actions can be taken that will at least temporarily retain heat on the veranda. For example, it is important to carefully caulk wooden window frames, then seal all the cracks, cover the outside with plastic film, but leave space between the window and the film - this gap (air cushion) will prevent the accumulation of moisture.

Additional measures

If your veranda is functionally an actively used room: there is a dining room or office area, then it is also worth considering the installation of a UV or electric heating device.

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. Now we lay insulation material between the bars.

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 insulate external walls. 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.

Finishing material, such as lining and the like, can be attached on top of this structure.

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. 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, stuffed wooden planks to secure the insulation, the voids are blown with special polyurethane foam and the whole thing is sewn up with clapboard or other finishing material.

If you have a large part of your veranda window frames, then we recommend that you install a triple frame structure. Because heat loss for the most part goes through the windows.

Before you start insulating your 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 just do additional design, which 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 outside extensions. 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.

Verandas (terraces) of private houses and summer cottages are usually not heated, so they are used as living quarters only in the summer, late spring and early autumn. In winter, they serve as a kind of vestibule, in which only skis and sleds can survive. Is it possible to turn a cold veranda into extra room? Yes, you can. A properly insulated terrace will keep the house warm, the walls unheated room They will no longer freeze and become damp, and if you spend money on installing a heated floor or turn on the heater, you can fully use the “summer apartment” on frosty days. The choice of thermal insulation material and insulation method depends both on the solvency of the property owners and on the stage at which the work is carried out: during the reconstruction/expansion of the house or during construction from scratch. How to insulate a veranda for winter living will be discussed below.

How and where does heat go?

On cold days, heat can escape from the house in all directions: up, down and to the sides, that is, you should consider thermal insulation of the entire “envelope”: ceiling, walls, floor, windows and terrace doors. Many homeowners are mistaken in believing that heated air always moves upward. This is only one form of convection, in which warm currents primarily rise from the floor. In fact, they move in all directions. General rule: The greater the temperature difference, the greater the heat flow. Thus, the colder it is outside, the faster the heated air leaves the house.

An insulated terrace will “save” heat throughout the entire house

Is it possible to completely eliminate heat loss? Clearly not. But you can significantly reduce it by insulating the veranda according to all the rules. To do this, you need to know through which parts of the room the heated air “floats”. About 30–40 percent of heat loss typical house falls on the walls. The roof “takes” about 25 percent, windows and doors - approximately 20, and the floor - 10. A fairly large leakage of heated air occurs due to drafts, excessive ventilation and lack of tightness.

Review of thermal insulation materials

What properties do heat insulators have?

Thermal insulators are distinguished by structure: some resemble wool, others have tiny cavities - pockets filled with air, which has low thermal conductivity. The first include common mineral fibrous materials produced in rolls or in the form of dense “felt” slabs. The second are polymer-based insulation materials produced in the form of panels or foams.

Most wood-based products, such as MDF, plywood, and fiberboard, also have low thermal conductivity. Therefore, wooden doors, finishing MDF walls, covering the hatch to the attic with clapboard helps to retain heat.
Some sealants also “work” as heat insulators. They seal cracks and gaps. One of the cheapest sealants is papier-mâché; it can be easily made from paper and wallpaper glue.

Good insulating materials not only slow down the process of heat loss, but also have other important properties: fire resistance, indifference to chemicals, wear resistance, non-toxic, antimycotic (prevents the development of mold). However, one more significant factor is cost, therefore, when choosing thermal insulation materials, they are guided by the notorious price/quality ratio. We should not forget about the requirements set out in regulatory documents(GOST 16381-77, GOST 22950-95, GOST 31913-2011 and others).

What materials are used to insulate the veranda?

Most often, the following is used to insulate walls, ceilings, floors, windows and terrace doors:

Mineral (glass, stone, slag) wool – fibrous material, high temperature resistant. Thermal conductivity depends on the density of the wool.
Expanded polystyrene (foam), including extruded polystyrene, is an inexpensive, fairly durable thermal insulator, the main disadvantage of which is its high fire hazard. When burned, it releases toxic substances. They produce modified self-extinguishing polystyrene foam with fire retardants (marked “C”). Fire-resistant boards are much denser and heavier than the types of polystyrene used for packaging. Extruded polystyrene foam 50 percent more efficient (for the same thickness) than standard mineral wool products.
Penofol is foamed polyethylene, covered on one or both sides with a layer of aluminum foil. Such “sandwiches” of metal foil and plastic insulator are used to reflect radiated heat.
Polyurethane foam in the form of panels or polyurethane foam(foamed polyurethane foam) - a material with low thermal conductivity (0.03–0.04 W/(m K) and high adhesion. Foam is formed by mixing chemicals. When hardened, it “locks” air in tiny pockets. Because foam can fill cracks and cracks, it is used to seal existing building structures, which helps eliminate drafts. Foam adhesive tapes are used to insulate windows, doors, and attic hatches.
Cork sheets made from cork oak bark are an environmentally friendly, but very expensive heat insulator.
Expanded clay is porous granules obtained by firing clay. Used as backfill for insulation of floors and ceilings.

Foil penofol reflects about 95 percent of thermal energy

Vacuum insulating panels - innovative technology in insulation

A relatively new material, successfully used in Europe and gradually conquering the domestic market, is VIP vacuum insulating panels. They help out in cases where saving space is the main factor influencing the choice of material. Minimum thickness insulation allows you to maintain the height of the ceiling and eliminates the need to create a threshold between the terrace and the adjacent room.

Thermal conductivity of the panels is 0.007W/(m K). In terms of thickness/degree of thermal insulation ratio, this is the best of all available materials for insulation. VIP systems usually consist of vacuum panels with high degree insulation and sealing strips of appropriate thickness. Such panels are usually installed along the outer edge. Manufacturers of vacuum panels supply kits with attached instructions demonstrating optimal scheme placement of panels and sealing tapes, which helps reduce the thickness of the insulation system to a minimum. The new heat insulator has one drawback - the material is expensive.

Ultra-thin VIP vacuum insulation panels are 20 times more effective than traditional insulation materials

How to insulate a veranda from the outside

Pros and cons of external insulation

All dirty work is carried out outdoors.
The veranda area is preserved.
The freezing point extends beyond the outer boundary of the walls.
The whole design resembles a thermos: it keeps the room warm in winter and cool in summer.

The disadvantages include the difficulty of performing reconstruction in bad weather.

To carry out work on insulating the veranda, no permits are required, therefore, having decided on thermal insulation materials, we begin the process. It is advisable to insulate the outside of the room in the warm season.

Ceiling insulation

If the veranda and the house have common roof and attic, then insulating the ceiling will not be difficult. Most convenient way– filling the frame cells with heat-insulating material.

Important! It is necessary to take care of vapor barrier.

What material should I use? Few a budget option: roofing felt is spread overlapping or the sheets are joined and glued, and a layer of expanded clay is poured on top or mineral wool slabs are laid. If possible, it is better to use foil-coated penofol, which retains heat well and does not allow moisture to pass through.

Ceiling insulation diagram from the attic side

Wall cladding with thermal insulation material

The easiest way is to line the walls with sandwich panels, which use mineral wool, expanded polystyrene or polyurethane foam as insulation. The main advantage of such insulation is the combination of thermal insulation with external finishing, and you can choose almost any option for the outer layer: metal, PVC, and so on. When choosing decorative log or siding sandwich panels, the exterior of the house completely changes.

Thermal insulation with panels made of polystyrene foam, polyurethane foam or mineral wool is performed in two ways:

If the veranda is insulated in wooden house, then first the sheathing is placed on the walls. The pitch corresponds to the size of the panels used. Then the insulation is attached with special dowels (“umbrellas”), on top of which the waterproofing layer is fixed with a stapler. Insulated walls are covered with siding, plank, clapboard or any other finishing material - the choice is huge.
On brick or concrete walls The heat-insulating panels are fixed with mounting adhesive. Then a reinforcing mesh is attached, plastered and painted or a suitable facing material is used.

Insulation scheme brick wall outside

Insulation of windows and doors

Ideally, it is advisable to install a ready-made entrance door with the provided thermal insulation (for a private house). If it is not possible to replace the door, then you should insulate the old one. To do this, foam rubber (you can get by with a blanket) is fixed with a stapler or glue, then leatherette is attached with furniture nails. A seal is laid around the perimeter of the door.

Thermal insulation is provided in ready-made entrance doors for private houses

It's the same story with windows. It is optimal to replace old windows with double-glazed windows. If this option is not feasible for any reason, insulate the outside with ordinary plastic film. To do this, slats are stuffed onto the frame, and the film is attached to them with a stapler.

Do-it-yourself insulation of the veranda from the inside

How to insulate a ceiling

If the roof structure does not allow external thermal insulation ceiling, you have to “take away” the height from the room and insulate it from the inside. A frame is mounted on the ceiling, taking into account that the cross-section of the beam must correspond to the thickness of the insulation boards. Using umbrella dowels, the heat insulator panels are fixed and a film is laid to protect against steam. The resulting “sandwich” is covered with plasterboard. If you don’t want to lower the ceiling height, then use vacuum insulating panels, which take up virtually no space.

Important! Be sure to insulate the hatch to the attic: seal the cracks, lay a seal around the perimeter, and sheathe it.

Veranda ceiling insulation technology

Thermal insulation of walls

They begin work by removing the old coating and cleaning the walls from dust. When using mineral wool or expanded polystyrene, first prime the surface and lay a layer of waterproofing. Then the frame is mounted (it is more convenient to use metal profiles) and the thermal insulation panels are attached. The insulation is covered with a vapor barrier film. The final stage is installation of drywall, puttying and application of the finishing coat.

Changing the location of the dew point when insulating walls from the inside

Experts advise using ready-made heated electric floor modules to insulate walls from the inside and turning on the system on cold days/nights. This method of insulation is very expensive, but it guarantees dry and warm wall.

Thermal insulation of windows and doors

Double glazing is considered effective way reducing heat loss, however, is relatively expensive. To save money, you can “preserve” the window for the winter in another way: attach a regular film to the frame using double-sided adhesive tape. Yes, it’s not entirely aesthetically pleasing, but it’s warm. It is advisable to seal all cracks with self-adhesive foam strips. You can do it the old fashioned way: with paste and paper, after caulking it with cotton wool or foam rubber. Thick curtains with thermal lining – additional method protecting the veranda from heat loss through the windows.

Even when installed modern doors with thermal insulation from below it usually “pulls”. In Europe, it is customary to make a special roller and place it under the door. The British jokingly call him a dachshund. Making such a “dachshund” is simple: stuff the stocking with old socks or other rags and tie it (the length of the “sausage” should be equal to the width of the door). The top decorative “pillowcase” can be knitted or sewn.

Insulation of the floor on the veranda

Thermal insulation of the floor from the basement

If there is a basement under the veranda, then insulating the floor is easier - there is no need to dismantle the existing flooring.
Stages of work:

along floor beams and back side Vapor barrier material is attached to the flooring using a stapler or mounting adhesive;
if the distance between the beams significantly exceeds the width of the insulation boards, side faces“increased” with slats, bars or metal profile, leaving a step a couple of centimeters smaller than the size of the material (the mineral wool block should be tightly fixed in the cell);
install thermal insulation panels;
lay a layer of vapor barrier;
installing a rough ceiling.

Insulation scheme wooden floor

Other floor insulation options

If there is no basement under the veranda, floor insulation work is moved indoors. If the owners of the house do not plan to start major renovation terraces, then tearing down the old flooring just to lay thermal insulation is not worth it, since the result will be too labor-intensive and costly a method of insulation. Typically, logs are installed on top of the existing covering, expanded clay is poured in, or insulating panels are laid and a new floor is laid. True, in this case the floor level rises higher and a threshold appears between the veranda and the next room. How to avoid this? Vacuum insulating panels “soldered” into MDF can be used. They will raise the floor by only 30 mm. The second way is to dismantle part of the covering and insulate it with ecowool, but this will require special equipment, since the composition is supplied under pressure. Another option is to install a “warm floor” system. You can do with little: carefully seal the gaps between the floorboards, fit the baseboards well and lay a thick carpet on the floor.

Insulating the floor over the existing coating

Note! With any method of insulation, one must not forget about reliable waterproofing.

Video lesson: insulating the walls of the veranda from the outside

Insulating a veranda, despite the abundance of thermal insulation materials and the apparent simplicity of their installation, is a rather labor-intensive process. Therefore, it is better to entrust the work to specialists construction company. They will produce necessary calculations and insulate the veranda according to all the rules.

In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, renovations in an apartment or house were done on a turnkey basis with all necessary types works

If you have a house or cottage outside the city, then you probably had to think about how to insulate the veranda for winter living. This is far from an idle question - and even if you don’t sleep there, warm room in front of the main building significantly saves energy costs for heating.

Today I want to tell you how to make insulation in a private house with minimal costs, taking two paths separately, or combining them with each other.

Two directions in insulation

Let me make a reservation that a veranda is usually called an open or glazed room attached or built into the main building. It is noteworthy that we are not talking about heating here, therefore, it is possible to insulate both a plank and a stone extension only in other ways.

Option 1: double-glazed windows

Since we are talking about insulating a veranda in a wooden house (brick, stone), then, of course, this means not an open, but a glazed room:

main source cold the temperature in this case is the windows, of which there are, of course, a lot, but this, alas, is an integral part of such a room;
therefore, we can reason like this - if we cannot reduce the number of windows in a given room, which are the main source of cold, then we need to somehow reduce the conductivity of this bridge;
the only thing we can do in this case is to install frames (plastic, aluminum, wood) with double-glazed windows (single, double, triple);
Of course, with such glazing the price of windows will increase significantly, but you get high-quality products that will not make worse interior or the exterior of the room, and even improve it;

of course, the frames themselves cannot be neglected, especially if they are made of aluminum, which is an excellent thermal conductor;
if the stained glass windows are made from this particular material, then make sure that it is “warm” aluminum, for example, as in the top schematic image.

No matter how you increase the thermal insulation capacity of the ceiling, walls and floor with your own hands, all your efforts will come to naught with single stained glass windows. It will be the same as if you put on a hat and boots, but at the same time remained in only your underwear in the cold.

Option 2: floor, ceiling, walls

One of the most powerful sources of cold in a room can be a floor that lacks hydro- and thermal insulation, especially if the building is located in northern regions our country. Let's start with waterproofing.

Any moist substance is an excellent conductor of cold, not to mention problems such as dampness and rotting. Therefore, if the shut-off waterproofing was not laid during construction, then it must be installed now.

It can be roofing material or dense polyethylene film(I am not mentioning the vapor-permeable film - it is too expensive, and besides, you can completely do without it).

And now - about materials for insulation. For example, mineral wool, polystyrene foam, extruded polystyrene foam and, of course, expanded clay - the cheapest and most reliable component of country construction.

I would also like to say about the sand pillow, if you add it, of course. Waterproofing should be laid not on it, but under it - this way we will minimize the amount of moisture from below.

The ceiling can be insulated both from the inside and outside - it all depends on what kind of roof is on your veranda and, of course, on your desire. Regarding the material here, the same can be said as for the floor, but it all depends on its location - from below, of course, it is much more convenient to use foam plastic or mineral wool.

But, if you consider that verandas mainly have pitched roof, then there is no attic there, therefore, in 99% of cases the insulation has to be hemmed from below, that is, internal installation must be done.

In order to do internal insulation, you will have to mount any of suspended ceilings, for example, like the one in the photo above, for . But insulating the veranda from the inside with your own hands in this way may not always work out for the most trivial reason - low ceilings, which, well, it’s simply impossible to lower another 5-6 cm.

In this case, there is only one thing left - to install some kind of insulation under roofing material, only with good waterproofing. And this will be more difficult, since you will have to dismantle and then reinstall the roof.

Well, finally, let's look at how to insulate a cold veranda for living space inside or outside along the walls. Let me note that there is nothing new to say here. In such cases, as a rule, mineral (preferably basalt) wool or polystyrene foam is used.

The thickness of the material directly depends on the need, that is, on the thickness and climate of the region. There is one small nuance here - if the insulation is installed outside, it will bring more benefits than from the inside, and you can see its effectiveness in the diagram above.

Another point - by insulating the room from the outside with polystyrene foam, you get the opportunity to “ wet finishing" That is, you can tile the veranda decorative plaster directly on the foam (of course, with a reinforcing plaster mesh).

Conclusion

Insulating the veranda either from boards from the inside or from any other materials from the outside is beneficial only if there are no drafts and there are windows with bags. Do you have any questions or suggestions? Write about it in the comments.
