The best material for insulating the outside of a terrace. Do-it-yourself insulation of a wooden veranda

Insulating a house is closely related to the issue of protecting materials from steam and water. Before you begin to insulate heat, you need to decide what materials can be used in these conditions, or what additional protection will be provided from excess moisture.

To combat moisture in insulated structures, a method is used to increase the vapor transparency of subsequent layers, and also, the access of steam is limited using a vapor barrier, and ventilation of the structures is arranged.

How dew is formed and why regulate the movement of steam

Water vapor in the air will begin to condense if the temperature drops sufficiently. For example, when you open the freezer, you may notice fog - drops of water form when warm air suddenly cools.

Or a cold bottle fogs up - dew falls on it, since its temperature is below the dew point for the existing air humidity.

In any building envelope during the cold season there will be a temperature at which water vapor will begin to condense and water will form. For homogeneous walls this is not noticeable, since they dry quickly.

But for insulated multilayer structures, the process of water condensation becomes more than noticeable, and if the control of steam movement is not carried out correctly, an emergency situation arises.

Water from the insulation can literally flow in a stream, accumulate in volumes of “buckets and barrels”, wet all the materials from which the house is made and they quickly become unusable as a result. those. steam condensation threatens to destroy the house. And all because of improper insulation and use of vapor barrier.

How to prevent insulation from getting wet

To prevent the accumulation of water and soaking of the structure when insulating the house, it is necessary to perform steam regulation.


The basic rule for multilayer structures is as follows. In the direction of steam movement, each subsequent layer should be more vapor-transparent than the previous one. In the cold season, the direction of steam movement is from the room to the outside. Accordingly, a wall insulated from the outside must have a resistance to steam movement greater than the insulation layer.

Another option to prevent condensation is to lower the humidity at the dew point. To do this, a vapor barrier is installed on the side of the room in the path of steam movement, and ventilation is installed on the side of cold air (lower partial pressure).

More precisely, air movement is organized directly above the insulation, which is placed vertically or obliquely in the ventilation gap from bottom to top. The air moves due to heating by heat entering through the insulation and the resulting thermal depression.

What materials are used for insulation and vapor barrier

For insulation, insulation materials of completely different vapor transparency can be used. Cotton insulation has a vapor transparency only 2 times less than that of air. And foam glass is already an absolute vapor barrier; it is believed that steam does not pass through it at all. Extruded polystyrene foam is close to these characteristics.

Polystyrene foam occupies an intermediate position. Its vapor transparency in a layer of normal thickness is sufficient for external use on walls made of heavy (non-vapor transparent) materials, but it cannot be used on vapor transparent wood, foam concrete, porous ceramics, etc.


For vapor barriers, continuous films are often used made of polyethylene and polypropylene. Polypropylene is more durable. Films are often made two-layer or three-layer.

Additional layers of woven materials add durability. Sometimes a vapor barrier is made with a base layer of foil, for conditions high temperatures, when insulating steam rooms of baths, in under-roof spaces with metal tiles and etc.

When insulating, another type of film is used - diffusion membranes. On the contrary, they allow steam to pass through them, but create resistance to the movement of water.

The easier such a membrane allows steam to pass through. the higher its quality, and its choice is preferable. These membranes are necessary to cover the surface of cotton insulation, prevent the blowing out of insulation fibers, level out wind pressure, and protect the insulation from water ingress.

Design options

If the design is not solid partition, then from the side of the steam source (from the side of increased partial pressure) any insulation is fenced with a vapor barrier to prevent drafts through its layer.

For example, when placing insulation between the stiffening ribs of a fence on a loggia.


The greatest amount of steam tends to escape through ceiling and through the roof. The vapor-transparent insulation in these places must be protected by a vapor barrier, which is installed from inside the house.

At the same time, a superdiffusion membrane (more than 1200 g/m2) is placed above the insulation, and a ventilation gap of at least 3 cm in height is installed above it.

When insulating attic floor It is also advisable to create a gap of at least 1 cm under the vapor barrier using counter slats, onto which the interior trim of the attic is attached.


When insulating wooden floors It is mandatory to waterproof the structure against steam coming from the soil under the house. All layers of the floor structure (including those with high resistance to steam movement) are insulated using a strong, durable vapor barrier.

More often, 2 layers of roofing material are used here. At the same time, a ventilation gap is made above the insulation, which is located between the joists.

But vapor barriers are usually not used for load-bearing walls of buildings - it is enough for the rule of vapor transparency of layers specified above to be met.

Those. on foam concrete, wood, etc. should be applied cotton insulation, and on heavy materials Expanded polystyrene (foam) of medium permeability can also be placed. But, at the same time, from the street side (lower partial pressure in the cold season) the insulation on the wall should be well ventilated.

For vapor-transparent cotton wool, ventilation gaps are created using additional sheathing. And dense slabs are plastered, painted, and finished only with special non-vapor barrier materials.

The situation is somewhat different in a three-layer wall, with a conventional external cladding brick. Since the principle of reducing vapor transparency is difficult to observe here, it is recommended to introduce a vapor barrier into the design, which is superimposed on load-bearing wall and use insulation that does not accumulate water. As a result, the layers are separated by a vapor barrier and exchange steam on only one side.

Vapor insulation for internal insulation

It remains to be reminded that when insulating from the inside of a room, a dangerous situation arises, since the surface of the wall from inside the room in the cold season will be at a temperature below the dew point.

Therefore, you should always avoid internal insulation, and if this is not possible, then use only a continuous layer of non-vapor-transparent insulation inside the building, which would itself create a barrier to the movement of steam to the dew point (to the wall).

Applying vapor barriers from inside the building onto the insulated wall is not a solution, since water can accumulate on both sides of such an insulator.


But the specified insulation from the inside is applicable only for low-transparent walls. If the wall materials allow steam to pass through well and can accumulate water (foam concrete, wood), then it is better to avoid insulation from the inside altogether, since condensation of water inside the wall and its dampening becomes inevitable.

As you can see, the rules of steam regulation are not complicated; they can be followed when individual construction without going into complex thermal calculations and insulation design. But you cannot neglect the rules for placing insulation and vapor barriers, since the consequences will be more than serious...

The idea of ​​adding a veranda to your country house is quite rational, but it is not enough to just lay a foundation and build a box on it - you need to think about thermal insulation. An uninsulated veranda will very quickly become unusable, and you will feel discomfort with the onset of the first cold weather - condensation will appear on the walls, and it will be replaced by black mold and mildew. To prevent this from happening, you should provide protection for the walls, floor and ceiling. This is what will be discussed in our article.

Today on the market you can find scary a large number of very different thermal insulation materials for every taste and budget. In most cases thrifty owners they prefer polystyrene foam or mineral wool - they are inexpensive and hold heat well. But when using, say, polystyrene foam, you should remember the measures fire safety– it does not burn, but melts, releasing toxic black smoke. Therefore, if you are planning to organize a kitchen on the veranda, it is better to refrain from insulating it with foam plastic.

As additional insulation A foam pad is used. Thanks to its metallized layer, penofol perfectly reflects ultraviolet radiation outside, thereby keeping the indoors cool in summer and warm in winter. Penofol consists of a layer of foamed polyethylene and a layer of durable aluminum foil. It can be used as additional or completely independent thermal insulation, but to achieve maximum effect it is recommended to combine it with other materials, for example, polystyrene foam or polyurethane foam.

Polyurethane foam is also inexpensive and effective material for thermal insulation of residential premises. It is not subject to combustion and exhibits excellent results even with very low temperatures.

Foundation insulation

The veranda is not only an additional living space where you can relax or receive guests, but also a kind of buffer zone for the main residence. During the cold season, it provides additional thermal insulation for front door. Therefore, the better the veranda is protected from the cold, the warmer the house itself will be in winter.

It is necessary to start insulating the veranda from the very base - from the foundation. In general, this should be taken care of during its laying, but if the moment is missed, there is a way to fix everything. The most important thing is to know where the main “loopholes” for cold flows are located and act purposefully.

Usually the veranda is built on the same type of foundation as the main house - concrete plates or monolithic strip foundation. Despite the reliability of the structure, concrete does not at all prevent the penetration of cold that comes from underground, so the foundation and the house built on it can freeze thoroughly. It has been proven that up to 25% of heat escapes through an uninsulated foundation.

There are several options for insulating a veranda with your own hands. You can fill the space between the foundation segments with soil or expanded clay, but this is only possible when building a veranda, otherwise you will have to dismantle the floor to the base. Filling with earth will be cheaper, but it retains heat much worse than expanded clay (foamed clay). Many for savings and good result combine insulation materials, alternating layers of earth and expanded clay.

Pasting with polystyrene foam

Most of the territory of Russia is covered with heaving soils, so the foundation built on them requires additional strengthening and insulation. To do this, the outside is covered with polystyrene foam. This material is a reliable insulator that prevents the foundation from directly contacting the ground during expansion (swelling), maintaining its integrity and strength. Expanded polystyrene is sold in large slabs, which should be used to cover the entire surface of the foundation from the outside, not forgetting to protect the base.

Foam and liquid polyurethane foam are varieties of expanded polystyrene and differ in price and operational characteristics. Foam plastic is the most a budget option insulation. It retains heat well indoors, but is not suitable for highly mobile soil (it will crack and crumble over time). The main disadvantage of polystyrene foam is its ability to take moisture from the ground, so if you are going to do such thermal insulation, you should take care of a good waterproofing layer, otherwise next year you'll have to start all over again.

Another thing is extruded polystyrene foam. It does not absorb moisture and is suitable for heaving soils, has excellent frost resistance and can last about 50 years. The only drawback is the impressive cost, but in this matter it is better not to skimp on quality, especially if you are building a veranda for the house in which you live permanently.

To reinforce with polystyrene foam or polystyrene foam, you should excavate the foundation to the ground. The first row of material must be placed on a gravel bed, having previously coated the foundation bitumen mastic(waterproofing). After the mastic has dried, you can glue the slabs using a special polyurethane foam adhesive, which is applied spotwise or spread over the entire slab. The joints between the materials should also be glued to eliminate the risk of cold bridges.

Polyurethane foam spraying is in the newest way insulation of foundations. This requires special spraying equipment and professional skills. The good thing about this method is that it allows you to very quickly create 100% thermal insulation of any foundation or wall. Having hardened, the material becomes very strong and durable, however, the cost of such insulation will be much higher than pasting with slabs.

Floor insulation

When the foundation insulation work is completed, it is time to work on the floor. This is a mandatory step, which determines whether you will enjoy seeing black mold in the corners or not.

If you are planning to pour concrete on the veranda and plan to heat it using a “warm floor”, you should take care of everything at the stage of working with the subfloor. Opt for electrical systems that can be turned on as needed and regulate the temperature. This way you will save impressive amounts on electricity.

The area of ​​the walls is the largest compared to the ceiling or floor, so they require thorough insulation. Fortunately, this is no more difficult to do than with the floor. The only “stumbling block” that most inexperienced self-taught builders have is whether to insulate the walls from the outside or the inside? Opinions on this matter differ, since each situation is individual and depends on climatic conditions, the material from which the walls are made, the type of insulation, the thickness of the walls, etc. Finding out all this can take a very long time, but if you want to get a 100% result, it is recommended to do insulation on both sides.

The image below very clearly shows how heat loss occurs when different types insulation:

Insulation from outside

Insulation should begin in the spring, when all the snow has melted and you can work for a long time on fresh air with various solutions and construction mixtures. From the outside, the veranda can be insulated with polystyrene foam or polystyrene foam using special fasteners - “mushrooms”. This is a special type of fastener that distributes the load of the slab, ensures its tight fit to the wall and ventilation.

It is recommended to pre-treat the wall with protective mixtures against fungi and dampness, then glue the “mushrooms” and slabs of expanded polystyrene or polystyrene on them. A fixing mesh is placed on the slabs, and on top of it you can already apply plaster and begin finishing facade.

Finishing can be done using various plaster compositions. You can learn more about which plaster to choose and how to work with it in the article.

There are other insulation technologies, for example, combining polystyrene foam with a vapor barrier and finishing the facade with siding, or using an insulating film and a block house. In this case, you should focus on the amount you plan to spend.

Insulation from the inside

Insulating the veranda from the inside will help achieve better results and retain precious heat in the house. When you're done with external finishing, you can move inside and properly work with the walls.

How it happens internal insulation walls:

  1. Caulk all the cracks if you have a wooden veranda.
  2. Fill the sheathing with wooden slats.
  3. With help construction stapler fix the waterproofing film to protect the insulation from moisture from the street.
  4. Attach a frame made of metal profile.
  5. Lay drywall into the frame and fill the space with mineral wool or any other insulation material of your choice.
  6. Cover the insulation with a layer of drywall.
  7. Apply topcoat.

In this case, drywall provides a perfectly flat wall surface on which wallpaper, putty, paint or even artistic painting will perfectly fit.

Ceiling insulation

If you have even a superficial understanding of air circulation, then it should be obvious to you that almost as much heat escapes through the ceiling as through the floor. An uninsulated ceiling will negate all work to preserve heat inside the room and will also create ideal conditions for condensation to form, which will lead to mold and mildew.

It is best to insulate the veranda ceiling with foil foam polymer material, which will simultaneously reflect heat and keep moisture out. Mineral wool will also work, but in this case you need to put roofing felt (waterproofing) as the first layer, take care of the vapor barrier, and only then put insulation.

We hope the above information will help you figure out how to insulate a wooden veranda with your own hands and make your home more comfortable even in the dead of winter.

If you added to yours in the summer one-story house veranda and, for example, equipped there comfortable kitchen, 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 attached veranda use mineral wool and... 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 maximum effect Preservation of heat will be achieved by combining it with other types of insulation.

Effective insulation options include resol foam, basalt wool and polyurethane foam. This 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 question is described 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 it on top masking tape(you can take a regular one).

ATTENTION: use polyurethane foam free of 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? Better than words This point will be clarified by the illustration below:

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. attached with glue or double sided tape. A reflective foil layer will retain heat in winter period and coolness - in the summer.

Step 4: making a cold floor warm

Finally, we install the floors. In theory it needs to be laid 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.

The final stage

As finishing you can use the most different variants. 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.

    Last year I also insulated the veranda, and now it doesn’t heat up in the heat, it’s always cool and relatively warm in winter. In principle, I did almost everything as described in this useful information for those who have never done this before. I insulated it from the inside, first “Izospan” is a vapor barrier, chopped up bars 50/50, then put in “Ursa” mineral wool, again a layer of vapor barrier and then lined it with clapboard. Of course, the area of ​​the veranda decreased, but the result was positive, which is what I wanted and achieved. I chose mineral wool because mice don’t like it; it’s very unpleasant when they get between the walls.

    During the renovation, we also faced the issue of insulating the apartment (our house is old, two-story, the apartment is on the second floor). First they decided to insulate the inside, they insulated it with mineral wool. In terms of money, of course it was more expensive, but there is more confidence that it will not freeze, and animals (mice, bugs, spiders) will not start. Then foam and drywall were laid. With the remaining money we decided to insulate the outside as well. Since we have heating system, then gas consumption is minimal, and the house is very warm.

    Valily 2013 said:

    Polystyrene foam is suitable where it can be glued to brick wall. Insulate wooden areas with mineral wool. Insulation will be successful if you end up with a thermos. Sometimes it seems that it is easier to build a new veranda than to insulate the old one.

    Irina said:

    Insulation should be both inside and outside. Saves payment for public utilities. I'll share mine personal experience. First, the inside walls were insulated with ecowool, then the walls were sheathed with plasterboard. Ceiling insulation is also done with the same materials. The floor was made warm - electric. They also insulated the outside with polystyrene foam (5-piece). Now it's cozy and warm. It turned out winter Garden for flowers. Try to use high-quality and environmentally friendly materials for interior decoration.

    Igor said:

    It is definitely necessary to insulate from the outside, because the air penetrates from the street, you can use glass wool, mineral wool, etc., pay special attention to the floor and walls, they can be coated with resin, then the wood will be strengthened and there will be a pleasant smell, it’s worth paying attention Pay attention to the windows, they also play a major role in retaining heat.

    Andrey said:

    I know on own experience and I advise you.
    When insulating, it is best to use mineral wool. Expensive? but high quality and environmentally friendly. Polystyrene foam will not give you such a result, and you will suffer (gaps remain, you won’t be able to cut them exactly anyway). If you decide to insulate, pay attention to the windows - metal-plastic windows most best option. And if you want to double insulate your veranda, then insulate it from the outside. It was not for nothing that our ancestors covered the house with dry stalks of reeds or corn for the winter.

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. Penofol can be used as additional insulation for the veranda.

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 slabs 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. Typically 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 wooden extension planned with "warm floor" technology, it is better to choose electrical system. It can be turned on as needed. Water heating You should not install it on a wooden veranda, since at low temperatures the pipes may freeze and become deformed, as a result you will have to completely change the system.

Floor insulation in an unheated veranda

The floor of the house is closest to the ground and if it is not heated, Substantial part 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. On next stage To insulate the floor of the veranda, logs from 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 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. First you need to change wooden windows to 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 quite in a 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.

Along the perimeter wooden box you need to install rubber seals. You should also check the connections door frame and 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. Old ceiling covering 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 most simple technology ceiling insulation – 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 you insulate cold veranda, you should think about wall insulation. They can be used both from the inside and from the street.

External thermal insulation

If the walls are wooden:

  1. First you need to seal all the cracks 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 the veranda 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. Insulation of a veranda in a wooden house with technology " warm seam» 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.

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.

It is difficult to imagine a country cottage or dacha without a veranda. Basically, such a building is used only in the warm season. But often, to increase usable area and operation of the premises in winter, they insulate the veranda attached to the house. How to implement this correctly and with minimal costs, we will tell you in this article.

Insulation methods

How to make a veranda suitable for winter living? It is advisable to consider the possibilities of thermal insulation at the beginning of construction, since after completion of the work, labor costs and financial investments increase several times.

Insulating a veranda involves installing insulation on the floor, walls, and ceiling. However, due to the influence of the atmospheric environment, not all types of materials are suitable for solving this problem.

The best option is roll and slab insulation based on natural minerals. They are sufficiently air- and vapor-permeable, which facilitates the free removal of moisture and protects the wood from rotting and deterioration.


Less preferable for the veranda artificial insulation made of polyurethane foam, which have low vapor permeability. These materials are more often used for external insulation; the slabs are pre-attached installed frame from timber.

Let's start from the floor

It is much easier to carry out measures to insulate the veranda during the construction phase. As a rule, such structures are made according to frame technology. This facilitates the process of laying insulation into the walls, floor and upper ceiling.

The first stage of preparing the structure for winter living is insulating the floor on the veranda. After erecting the foundation, a lower frame made of timber with a cross-section of 150x150 mm is installed on the supports and the sheathing is mounted. Before insulating the floor on the veranda, the wood is treated with a protective compound.

Next, the so-called subfloor of the veranda from edged or unedged boards 25 mm thick. If there is a subfloor, this problem can be solved relatively easily. If there is no necessary space under the floor of the veranda, 30x30 bars are attached to the side planes of the floor in the lower part, on which the subfloor is mounted.

An insulating material and a vapor barrier layer are installed on top of the fixed boards. Because lion's share heat loss occurs through the floor; 2-3 layers of insulation are laid on the lower floor, alternating directions at an angle of 90 degrees.

Instead of slab or roll insulation, solid materials are used, for example, expanded clay is poured between the beams. A layer of vapor barrier is laid on top and finishing cladding floor.

We insulate the walls

The next stage of insulating the veranda is insulating the walls. Vertical bars are attached along the perimeter of the floor and secured with the help of jibs and transverse horizontal inserts. The outside walls are sheathed with finishing material of one type or another, after laying a vapor barrier.

Between vertical posts install insulation in at least two layers.

As a rule, the thickness of the material allows it not to be fixed additionally. Enough to cut the pieces mineral wool 3-4 cm wider than the opening into which installation is planned.

After the vertical surfaces are insulated, sew finishing layer vapor barriers and perform interior wall finishing.

Working with the ceiling

It is impossible to properly insulate the veranda from the inside, bypassing the ceiling. Upper frame assembled similarly to the lower ceiling, that is, from wooden beams square section. In the case of sequential work, the ceiling is insulated before the roof is installed. To do this, the underside of the floor beams is finished with a final covering of the surface with preliminary installation of a vapor barrier.

The finishing is covered with insulation in several layers and covered with a rough ceiling. If the veranda does not require a separate roof with an attic, a sheathing is attached over the sheathing and the roof is installed.

Insulation of the finished veranda

It is much more difficult to insulate a building built several years ago. In this case, it is desirable to minimize dismantling work, which may damage previously installed finishing material walls, floor and ceiling. Let's take a closer look at the nuances of insulating a finished veranda.

Ceiling

If there is a need to rebuild the room for winter living, the installation of insulation begins with the dismantling of the interior finishing of the ceiling. The operation is performed carefully to minimize waste. As a rule, in wooden houses When finishing verandas, they use expensive material - lining.

After all the panels from the upper horizontal ceiling have been removed, begin installing the insulation. To prevent loss mineral slabs, proceed as follows:


Walls

As a rule, insulation of the finished veranda is carried out from the outside. This allows you to preserve expensive interior decoration. After dismantling the external wall cladding install a vapor barrier: the film is secured in the spaces between the racks using a construction stapler.

Insulating the veranda from the outside

Instead of mineral wool, foam plastic is used for external insulation of walls, which is resistant to atmospheric influences and is not afraid of the influence of microorganisms. The insulation of the veranda with foam plastic is carried out in a pre-installed sheathing, which ensures free air circulation.

Particular attention is paid to windows. It is better to install two- or three-chamber double-glazed windows.

If the windows for the veranda have single glass, all joints are treated with a special adhesive-based insulation, and the places where the frame fits are coated with sealant.

Floor

A large amount of cold air enters the room through the floor. Without high-quality thermal insulation winter operation a veranda is impossible, and heating costs increase significantly.

We begin work on laying insulation with dismantling flooring. Floor boards can be attached in several ways:


If there is rough sheathing, fasten vapor barrier membrane and lay expanded clay or mineral wool. At standard thickness It is recommended to lay 3 layers of mats or rolls of 50 mm between 150x150 timber. A vapor barrier is attached to the upper planes of the beams and the floor boards are mounted in their original place.

If there is no subfloor, make a false lathing from 30x30 pine beams, attaching it to the side planes of the beams with 70x4 mm self-tapping screws.


Thus, having studied the technology of insulating a veranda, even a novice master will be able to carry out all the work independently. Of course, it is better to insulate the room at the construction stage. But as a last resort, you can also insulate the finished veranda, spending an additional amount of effort, time and finances.
