Insulation of veranda walls with penoplex. How to make a vapor barrier when insulating

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 here in winter period time, 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 wooden house or a brick house. What materials to use when working? Should you insulate from the outside or from the inside? We will look at all this further.

Which method of insulating the veranda to choose

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

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

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

True, this method of insulation also has its disadvantages:

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

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

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

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

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

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

Insulation of the veranda - list of materials

Nowadays there are so many insulation materials that it is sometimes difficult to make a choice. All of them are good in their field and are used by builders. Nevertheless, over some time each material has received a certain reputation, so 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:

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

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

Penofol

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

Advantages of the material:

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

Mineral wool

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

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

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

PPU (polyurethane foam)

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

Advantages of the material:

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

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

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

We insulate the foundation of the veranda

High-quality insulation comes down to eliminating heat loss through each structure. After all, the task of insulation is not only to prevent the penetration of cold. The main task is to conserve the heat generated by the heating system of the room. It is noteworthy that the veranda is most often built on the same foundation as the entire house. Most often the base 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:

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

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

We insulate the floor in the veranda

The floor is another source of heat loss in verandas and terraces. Most often, the floors in the veranda are made of concrete screed. Sometimes wood is used (by the way, it is warmer). If you are planning to install a heated floor in your veranda, we recommend that you 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:

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

We insulate the walls of the veranda

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

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

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

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

We insulate veranda windows and doors

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

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

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

We insulate the ceiling of the veranda

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

There are two options for ceiling insulation:

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

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

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

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

Let's sum it up

So, you have learned exactly how you can insulate your veranda by insulating the foundation, ceiling, walls, floor, windows and doors. All you have to do is follow the advice, purchase the material and put everything you’ve learned into practice. As for heating the veranda, 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 calmly relax in it, do winter Garden or use for other purposes.

Veranda – best place It’s impossible to think of a place for relaxation, get-togethers with friends and family tea. When it's warm outside, the veranda becomes the most popular and crowded place in the house. But when the cold comes, it immediately becomes empty and languishes in splendid isolation.

But the situation can be easily corrected. To do this, you just need to insulate the veranda.

Of course you can hire construction team, which will insulate your veranda. But when everything is done with love and with your own hands, the veranda will be even warmer and more comfortable. In addition, insulating a room with your own hands will cost much less. Insulation work can be carried out at any convenient time.

In order to insulate the veranda with your own hands, you need to choose insulation. There are many types of room insulation on the building materials market. But the most popular are:

• mineral wool
• Styrofoam

In order to improve the insulation effect, you can use a gasket between the wall and the foam insulation.

If the veranda is wooden and there are foundation strips in it, then the floor must be insulated. To do this, the plank floor needs to be puttied and painted. Then the floor surface is covered with penofol. You can already lay carpet or warm linoleum on the laid penofol.

When you insulate the wooden walls of the veranda, you must tear off the old boards. Then use staples to attach it to wooden walls insulation with a layer of foil. Place MDF panels on top of the insulation.

It is a little more difficult to insulate the brick walls of the veranda. You will have to secure a frame of cross beams to the walls. Place insulation tightly between the beams.

To insulate the veranda from the inside, you can also use sheets of plasterboard. It's simple and fast. A metal profile frame is attached to the wall. Insulation (foam plastic, mineral wool or penofol) is tightly placed between the profiles. Drywall sheets are attached to the profiles using screws and a screwdriver.

One of the most economical options The insulation of the veranda is mineral wool. Cotton wool is light and has good thermal conductivity. Cotton wool consists of fibers between which there are many air bubbles. This is a peculiar air gap. Which increases the insulation effect.

The disadvantage of cotton wool is its hygroscopicity. Therefore, it will also be necessary to carry out a vapor barrier using penofol. A layer of penofol is applied on top of the mineral wool.

One of the most simple materials Penoplex is used for insulation. Using glue, foam sheets are attached to the walls.

IN in this case there is no need to carry out a vapor barrier, because the external and inner side penoplex has waterproof properties.

Apply on top of the insulation thin layer plaster and paint or wallpaper.

Or if you look at the process in general, it is quite applicable to insulation wooden house from the inside. More information about the work processes can be found at:

Foam insulation process

To insulate the veranda, the most commonly used material is polystyrene foam. By using polystyrene foam to insulate the veranda, you can save on building materials. Working with polystyrene foam is easy. Insulation with polystyrene foam does not require a lot of money.

Before you start work, you need to stock up on building materials.

You will need to buy:

1. polystyrene foam, the thickness of which is 5 centimeters or more;
2. tile spatula
3. glue, preferably Ceresit (to attach the insulation)
4. fiberglass reinforced mesh
5. painting corners (for slopes and corners)
6. umbrella dowels (to attach foam plastic), approximately 6 pieces per 1 m2 of foam plastic

Using a tile spatula (it is smooth on one side and has teeth on the other), spread the foam sheet with glue. Level it using the flat side of a spatula. Run a comb over the foam. We do the same on the wall. Press the foam sheet against the wall and tap it thoroughly.

Now you can fix the foam using umbrella dowels. Place the dowels in this way: one in the center, four in the corners. After the foam is glued to the walls of the veranda, it must be puttied. This work is more painstaking than gluing foam.

You can putty the wall covering using a mixture of CM11. To begin with, you need to stick a paint corner on all corners and slopes. This way the putty will stick to the walls better.

Insulating the veranda floor is the first step

Insulating the veranda from the inside should start from the floor.
All floor insulation materials can be divided into:

• natural
  • granular insulation
  • cellulose
  • cork
• artificial (all other insulation materials).

Materials for floor insulation can be divided by type:

• bulk
  • slag
  • expanded clay
  • foam glass
• liquid
  • polymer mixtures
• sprayed
  • penoizol
  • ecowool
• roll
  • cork
  • mineral wool
  • linoleum
• tiled
  • mineral and glass wool
  • gypsum fiber sheets
  • foam glass

Depending on the type of insulation, the floor insulation technology is chosen. The joists and screed will need to be laid under expanded clay, penoplex and mineral wool. Roll insulation you just need to roll it out and cover it with hard material (boards, laminate) on top.

Let's look at how to insulate a floor using mineral wool or polystyrene foam.

In verandas, the floor is usually made of logs, and boards are attached to them. First you need to remove the boards from the floor. Place wooden blocks between the joists and secure them with screws. Place insulating material between the bars.

Mineral wool or polystyrene foam can be used as insulation.

Please note that the insulation must be laid very tightly between the joists and fill the entire space.

If polystyrene foam is used as insulation, then its sheets must be adjusted to the dimensions of the space between the joists. The foam is cut with an ordinary knife.

If the insulation is mineral wool, then it must first be insulated with foil or polyethylene. This is done so that moisture does not affect the insulation. Empty spaces that remain after laying the insulation should be blown out with foam.

The height of the entire insulating structure should be several millimeters below the floor level. This gap is left so that there is air circulation and moisture is not retained. This will protect the floor from rotting and fungus.

But you can find a way to insulate the brick walls of a bathhouse. Remember that a poorly insulated bathhouse does not retain heat!

Insulating veranda walls - several inexpensive ways

The walls of the veranda can be insulated from the inside and outside.
Insulation from the inside can be done using sawdust:

1. Mix sawdust with lime (10:1) and sprinkle the insulation copper sulfate to prevent rodents from getting in.
2. Then a frame made of wooden beams is strengthened onto the walls.
3. Place insulation between the beams and compact it tightly.

Cork can also be considered as an option for insulating walls from the inside. Cork insulation is sold in rolls or sheets. The insulation is attached to the walls using dowels or glued.

One of the advantages of this insulation is its aesthetic appearance. After fixing the cork insulation, you don’t need to carry out Finishing work. He is beautiful in his own right.

The walls of the veranda can also be insulated using foam blocks. Attach the block slabs to the walls using dowels. It is good to blow out all remaining cracks with construction foam.

But this type of insulation has a significant drawback. When used, the area of ​​the room will be significantly reduced.

The veranda walls can also be insulated from the outside. To do this, attach the sheathing to the walls. Fill the cavities between the sheathing with moisture insulation and insulation. And already in last resort attaches the cladding. Siding or decorative panels are used to cover the façade of the veranda.

In conclusion, I would like to summarize the above:

• Insulation of the veranda from the inside must begin from the floor.
• The walls of the veranda can be insulated both from the inside and outside.
• When insulating walls, it is advisable to use a vapor barrier
• The cheapest and simplest insulation is polystyrene foam.

Video on insulating a veranda

Remember, all work on insulating the veranda with insulation can be done with your own hands. You just need to want it.

Or verandas on a suburban area - perfect solution to create additional living space that can be used throughout the year. Before insulating the veranda, you need to think through the main points of the work: type of insulation, thermal insulation material, place of installation of the insulator, etc. Insulation can be done both from the inside and outside.

Insulation from the inside is considered the most effective.

In this case, work can be carried out in any weather. In this case, you can use the same thermal insulation materials for walls, floors, and ceilings. At the same time, if the veranda has already been made and is not under construction, then the existing coverings will need to be dismantled. In addition, the freezing point will shift inside the wall material, which will negatively affect its performance characteristics.

At the same time, many experts are in favor of external insulation, who note that when carrying out work outside the veranda in a private house, the area of ​​the room will not be reduced. In addition, the freezing point will be shifted into the thermal insulation material, which will allow the walls to accumulate heat.

When installing external insulation, it will be necessary to ensure high-quality protection of the insulation from moisture and atmospheric phenomena, since almost all modern insulators are susceptible to the negative effects of humidity and temperature changes.

What materials can be used to insulate a veranda?

On modern market presents a huge number of the most different types thermal insulation materials having different characteristics and prices. The most common ones used in suburban construction, are the following:

• Penofol. If you ask a builder about how to insulate a veranda, he will most likely talk about penofol. Penofol is a modern thermal insulation material that is used separately from other insulators or together with them. Penofol is suitable for insulating various buildings in country house. It's environmentally friendly pure material with a minimum degree of vapor permeability, which can be installed with your own hands.
• Styrofoam. Probably one of the most popular insulation materials. Distinctive features: minimum weight, rigidity, stable performance over many years of use, ease of installation, the ability to install with or without a frame. But polystyrene foam is susceptible to fire and is also attractive to rodents. At the same time, when using this material there is no need to make an additional layer of waterproofing.
• Expanded polystyrene. A modern insulator that has all the advantages of foam insulation, as well as good strength characteristics and ease of processing. Among the disadvantages, one can highlight only low sound insulation performance, however, they are usually not required on verandas. Not flammable.
• Mineral wool. The most popular insulation that can be used everywhere in a private home. Well suited for insulating a veranda for winter use of the premises, but only in combination with other insulation and waterproofing. To install mineral wool slabs, a frame is required. In addition, after several years of operation, the material will begin to lose its density, which will lead to a loss of insulation properties.
• Basalt wool. Almost a complete analogue of mineral wool, although from an environmental point of view it is safer.
• Polyurethane foam. This is one of the most modern and effective insulation materials On the market. It can be produced in the form of slabs, panels, or applied to insulated surfaces using special equipment. Advantages: light weight, resistance to any natural and chemical influences, high thermal insulation properties, amazing durability (more than 40 years). The main disadvantage of this material is its high price.
• Linen, tow, moss. These traditional insulation materials can be used only in cases where it is necessary to insulate a veranda in a country house made of timber, as well as to caulk cracks at the joints. They cannot be considered as a complete thermal insulation material.

The choice of insulation or several insulators will depend on many factors: materials for constructing the veranda, the desired level of insulation of the room, the dimensions of the structure, etc.

It is worth noting that truly warm veranda, for year-round use, can only be achieved with high-quality insulation in combination with glazing and heating.

Warming the veranda floor

You can insulate the veranda floor in different ways. The two most common methods of carrying out work should be considered.

In the first case, it is necessary to completely dismantle fine coating premises, reaching the subfloor (concrete, beams, etc.). After this, it is necessary to completely cover the surface of the subfloor using expanded clay (or its analogues). Then, if there is space left, you can lay insulation boards, attaching them to the floor beams. Finally, the final flooring is re-laid.

Floor insulation with expanded clay.

The second method also involves dismantling flooring, however, work can be performed using it. If work is carried out according to available wooden floor, then in the future its surface will become rough. First of all, bars measuring 50x50 are installed on the logs or on the rough surface (depending on the chosen method), then the vapor barrier layer is laid. Insulation is placed on the vapor barrier layer (mineral wool slabs can be used). Laying is done in such a way that between wooden beams and there were no cracks or gaps left with the insulation. Existing gaps and cracks can be closed with construction foam.

Floor insulation with slabs.

We again cover the insulation material on top with a vapor barrier, turning the foil part inside the veranda. It is recommended to close all resulting joints with construction tape. Finally, the finished floor covering is installed.

In some cases, to ensure maximum thermal insulation of the floor, the foundation of the veranda is insulated, but often this is not required.

Insulation of the ceiling and roof of the veranda

It is difficult to imagine insulating a veranda from the inside with your own hands without creating a thermal insulation layer on the ceiling surface. The principle of work here is approximately the same as in the case of the floor. The main difference is that all installation work is carried out in a canopy, which is associated with some difficulties, so it is better not to do this alone.

The first method of insulating the ceiling of a veranda in a country house involves the use of a frame. Dismantling is carried out first ceiling covering, after which a waterproofing film is installed on the rough surface of the ceiling. If soft thermal insulation materials are intended to be used, then a frame can be made for them from timber, as a result of which an insulator can be mounted between the beams. After laying the insulation, it must be covered again over the entire area with a waterproofing film. The final finishing of the ceiling in this case is carried out plasterboard sheets or wooden clapboard.

The second method involves the use of polyurethane foam and rigid types of thermal insulation materials. In this case, the installation of insulating materials occurs directly on the ceiling surface, after which it is completely covered with putty.

In order for the putty to hold as securely as possible, it is necessary to cover the foam with a metal mesh.

Insulation of veranda walls

The insulation of a veranda very often begins with the creation of a thermal insulation layer on the walls. In this case, work can be done both inside and outside. A variety of thermal insulation materials listed above may be suitable for insulating veranda walls. Experts recommend not insulating the walls of the veranda using the existing finish - it must be removed before work, attaching the insulation to the rough surface of the walls.

Insulating the veranda with ecowool from the outside.

When insulating walls (no matter outside or inside), it is recommended to protect the thermal insulation using a waterproofing layer, for which modern waterproofing films. If slab insulation is used, then it is necessary to existing walls a small frame made of wood that will hold them in place.

Frame insulation of the veranda from the inside.

All gaps and cracks that will be formed between the insulation and wall material, it is necessary to caulk it with jute or fill it with polyurethane foam.

The most important thing is that there are no gaps through which cold air from the street will penetrate into the room.

Is there enough insulation?

If the veranda is intended to be used and maintained all year round comfortable temperature in winter, the insulation of the veranda must be carried out together with high-quality glazing of the room and the installation of heating elements. Heating the veranda can be done by the most different ways: installation of traditional radiators, installation of electric heaters, installation of “warm floors”, etc.

The choice here is quite large. But the main thing is compliance with safety regulations.

When choosing traditional radiators, the heating project will have to be coordinated with regulatory government agencies.

Verandas (terraces) of private houses and summer cottages are usually not heated, so they are used as living quarters only in 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 accommodation, 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. That's why 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, another 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:

1. Mineral (glass, stone, slag) wool is a fibrous material that is resistant to high temperatures. Thermal conductivity depends on the density of the wool.
2. Expanded polystyrene (foam), including extrusion, is inexpensive, quite durable heat an insulator, the main disadvantage of which is a 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 is 50 percent more efficient (for the same thickness) than standard mineral wool products.
3. 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.
4. Polyurethane foam in the form of panels or polyurethane foam (foamed polyurethane foam) is a material with low thermal conductivity (0.03–0.04 W/(m K) and high adhesion. Foam is formed when mixed chemical substances. As it hardens, it traps air in tiny pockets. Since foam can fill cracks and crevices, it is used to seal existing building structures, which helps eliminate drafts. Foamed adhesive tapes used for insulation of windows, doors, attic hatches.
5. Cork sheets made from cork oak bark are an environmentally friendly, but very expensive heat insulator.
6. 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

Relatively new material, successfully used in Europe and gradually conquering the domestic market - 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 build a threshold between the terrace and 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 typically consist of highly insulated vacuum panels 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

1. All dirty work is carried out outdoors.
2. The veranda area is preserved.
3. The freezing point extends beyond the outer boundary of the walls.
4. 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.

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:

1. If you are insulating a veranda in a wooden house, then first lay sheathing 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. Cover insulated walls with siding, plank, clapboard or any other finishing material– the choice is huge.
2. On brick or concrete walls assembly adhesive Thermal insulation panels are fixed. Then a reinforcing mesh is attached, plastered and painted or a suitable facing material is used.

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.

In ready entrance doors thermal insulation is provided 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 conventional 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 cross section timber 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 sheath 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:

• fasten along the floor beams and the back side of the flooring with a stapler or mounting adhesive vapor barrier material;
• if the distance between the beams significantly exceeds the width of the insulation slabs, the side edges are “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.

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 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

Insulation of the veranda, despite the abundance of thermal insulation materials and the apparent simplicity of their installation, is sufficient 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.

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 be donated great opportunity gather in winter with family and friends in a 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: polystyrene foam, mineral wool, polystyrene foam, polyurethane foam. The most popular are the first two: with their help you can transform a cold veranda into “warm” status and save your 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 be warm even in severe frosts, it is worth considering the option 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 the 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, 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 - this is a set of tools with which you can perform all the necessary manipulations to insulate the veranda.

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 do wooden beam 50x50 mm - after all, the insulation itself has a thickness of 50 mm.

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 moisture 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: it will be easy to attach the protective layer 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. The main condition is the mechanical strength of the base. If you choose this option, then first you will have to cover all the cracks in the floor with 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 should 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 on top chipboard sheets and what you liked finishing coat(carpet, linoleum).

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 a 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 various 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 movies, classical fine arts And the latest technologies. Believes that perfect interior should combine aesthetics and ergonomics and give an impression.

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 highly flammable material, but at high temperatures 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 ultraviolet radiation well, and practically does not burn, and retains heat at very high temperatures. 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 material finishing, budget, climatic conditions at the time of the insulation process. External wall insulation has a number of advantages over internal wall insulation. For example, when internal insulation the freezing point shifts 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 bag) 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.
