Insulation of the extension is an excellent opportunity to increase usable area buildings, reduce the consumption of electricity or gas for heating. With heating prices rising, a smart owner tries in every possible way to minimize costs and retain heat indoors as much as possible. To save more money, you can insulate an extension to a private house with your own hands, using photo instructions from the Internet.
In order not to panic with the onset of cold weather, you need to choose a seal that is resistant to moisture and temperature changes.
Selection of materials
The best option for the material used is foam sheets. They are lightweight, so they are quite easy to transport and are attached to walls both outside and inside.
In order to insulate the roof of a cinder block extension, it is better to choose polystyrene foam. Peculiarity of this material consists of its low vapor permeability and high thermal insulation even in conditions high humidity. This material will last for many years, since fungi and mold do not appear on it, it is not subject to rotting, and is fire resistant.
In a house made of timber, a large loss of heat occurs through the ceiling. Therefore, when planning to insulate a wooden extension to your house, start from the ceiling. It is good to use eco-wool for finishing floors. It's relative new material allows you to tightly seal cracks, rodents and microbes do not live in it, has excellent sound insulation and consists exclusively of natural ingredients.
To preserve heat in the veranda attached to brick house You need to take care of the thermal insulation of windows and floors. To do this, treat the cracks near the windows with polyurethane foam, and insulate the floor with polyurethane foam and make a screed. Polyurethane foam is resistant to moisture and steam; a sufficiently thin layer to retain maximum heat in the room; easy to transport; has good adhesion to any surface.
A well-executed project will help you calculate required quantity thermal insulation raw materials are still at the planning stage. To insulate an extension to a house, it is recommended to lay a layer of the selected insulation of equal thickness over all surfaces.
Today, there are a large number of videos that will help the homeowner independently carry out all the necessary work.
In this video you can see how best to insulate a wooden floor in an extension:
You can also look at .
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 an attached veranda, mineral wool and 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.
How 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 in this case What is important to us is the fact that they will be better than your old windows in terms of thermal insulation properties.
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 large diameter caps; you can also use small wooden plates so that the dowel caps do not go 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 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? 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, 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.
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.

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 to 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 encountered the issue of insulating the apartment (we have a house old building, two-story, apartment 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 autonomous heating, gas consumption is minimal, and the house is very warm.

Polystyrene foam is suitable where it can be glued to brick wall. Wooden plots insulate 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 play too main role in maintaining 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.
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. Frame extension to a wooden house can, in principle, be erected independently, but for this it is necessary to have construction skills and follow the rules and sequence 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 metal carcass, then covered 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.
- Foundation
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 not only spoil the external image the whole house, but also affect the life of the veranda. It is necessary to think over the layout, dismantle old buildings if necessary, ensure a good approach to the construction site, think through, etc.
Do-it-yourself insulation of the veranda of a wooden house
Since the veranda will be the place where noisy companies 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 the veranda is. 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 (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 them out 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 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. The insulation is then applied on top thin layer plaster, which is pasted over 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.

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:
- Work is carried out at any time of the year and in any weather.
- You can have free access to the surface at any height.
- 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:
- During operation, debris will not accumulate in the room.
- The space inside does not become smaller.
- Repair work can be done without disturbing your lifestyle. No one will have to move anywhere.
- The freezing point shifts into the insulation, so the walls will accumulate heat and not collapse so quickly.
- After insulation, the outside veranda can be decorated and transformed by covering it with clapboard, siding, decorative bricks or other facing material.
- 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 we can make a list of the most 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 thermal insulation verandas.
Advantages of the material:
- Low price and availability.
- Versatile, suitable for insulating ceilings, walls and floors.
- The material is very easy to work with.
- Has a high degree of heat conservation.
- Not afraid of moisture.
- It is light in weight and does not weigh down the structure of the veranda.
- 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:
- It can be combined with other materials, used as one insulation material or reinforced with others.
- It is environmentally friendly and will not emit toxic and harmful substances. Therefore, you can use it inside.
- It’s very easy to work with; anyone can do the insulation process.
- It is fireproof.
- 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:
- The material is vapor permeable, i.e. it is breathable. Thanks to this, the veranda will have an excellent microclimate and optimal humidity.
- This is an environmentally friendly product that will not cause any harm to anyone.
- The quality of insulation of mineral wool is excellent.
- The material is lightweight and easy to work with.
- Just like polystyrene foam, cotton wool has the ability to soundproof a room. None extraneous sounds will not penetrate the veranda.
- 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 with polyurethane foam, which after application increases several times. 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:
- No cracks.
- High quality thermal insulation.
- Polyurethane foam is not afraid of moisture.
- It is biostable.
- It is lightweight and has soundproofing properties.
- 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 serves 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:
- 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.
- Then you need to install the foam boards on the gravel bed and glue them to the foundation. Use polyurethane glue.
- 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 choose electrical system heating 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"by lags". Here's what you'll need for this:
- Make a subfloor from planks.
- Install logs on the boards. The height is selected taking into account the thickness of the future insulation.
- The logs and the space in them are covered with a waterproofing film, extending onto the walls.
- 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.
- The insulation layer is covered vapor barrier film, with an overlap on the walls.
- 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. But 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 start 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. On wooden box You can install rubber seals. Explore the places where 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 insulation of the ceiling from the inside:
- 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.
- 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.
- 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, then ideal option can be called 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.
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 this additional structure is 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. A 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 seats need to 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 tension on the insulation boards plastic film, the edges of which are fixed 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 fill wooden blocks on 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 ability to fill all the flaws and cracks with itself, creating even layer coverings. 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 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, stuffed wooden planks To secure the insulation, the voids are filled 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 most of the heat loss comes 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, your veranda, not protected by fireproof materials, will flare up at the slightest contact with fire and catch fire in a very 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 the option internal insulation verandas. 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, it won’t be easy to insulate a veranda with your own hands. special labor, the main thing is to determine in advance what to insulate and with what, and then it’s a matter of technology.
