Do-it-yourself insulation of the veranda from the inside for winter living in a wooden house - review of materials and step-by-step diagrams

Finishing a terrace in a private house (photo) The veranda is a small room attached to the house. It can be open or glazed (closed). It is used both for agricultural needs and for recreation. How to insulate a veranda for winter living from the inside with your own hands and what materials are best to choose for these purposes? You will find out the answers to these questions below.

Insulation of the veranda - list of materials

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

Styrofoam

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

Advantages of the material:

1. Low price and availability.
2. Versatile, suitable for insulating ceilings, walls and floors.
3. The material is very easy to work with.
4. 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 type of mineral wool is basalt wool. The material is biologically stable, does not burn, resists moisture and is durable

PPU (polyurethane foam)

An excellent material for insulation, which is applied by spraying. It can be compared to polyurethane foam, which increases several times after application. Although, on sale you can find ready-made panels that are mounted according to the foam plastic principle. However, this method is worse than the spraying method. Why? When fixing 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 properties.
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.

Types of insulation

There are 3 types of insulators, divided by structure. They have different origins and properties. Some may be dangerous to humans, because... When burned, they release harmful substances. To avoid this, you need to choose non-flammable insulation.

Cellular

Environmentally friendly, non-toxic materials, which include polystyrene foam, foam concrete, aerated concrete, foam glass. They have cells that retain heat; widely used on construction sites, because are inexpensive and have low thermal conductivity.

Fibrous

These materials, such as mineral wool, are made up of threads. Formaldehyde and acrylic compounds can be used as a binder.

Manufacturers claim that they are safe, but it is better not to risk your health and buy a more environmentally friendly insulator.

This is what basalt insulation is. It is made from molten rocks.

Bulk

Characterized by the presence of granules or grains. This can be sand or powder materials for backfilling. Polystyrene foam, broken into crumbs, is used as granular insulation. It is blown into the cracks by machine to seal it. The disadvantage of bulk insulators is that rodents can live in them.

The process of insulating the veranda

Insulating a veranda with your own hands is quite simple if you thoroughly understand all the stages of the work being carried out. Basically, the terrace is built on the same foundation as the house. Typically these are concrete slabs or a monolithically poured concrete base. In winter, 20% of the heat leaks through it, so before insulating the veranda, you need to insulate the foundation of the structure. This process is carried out without any particular difficulties. Polystyrene foam boards need to be glued to the surface of the base.

Floor

First of all, when insulating a terrace, the floor is insulated. Some people do not attach much importance to this process, limiting themselves only to the treatment of ceilings and walls, believing that it is not necessary to insulate floor surfaces and are deeply mistaken. In wooden verandas, the floor is often laid in the following way: logs are laid on the ground or concrete base, on which boards are then laid and installed. For insulation it is necessary to carry out the following steps:

• remove boards;
• between the installed joists it is necessary to secure wooden beams with screws;
• Insulation is placed in the resulting compartments - mineral wool, penoplex or foam boards;
• when settling mineral wool, additional insulation is required when using foil or film, which will eliminate the possibility of getting wet;
• the remaining empty spaces are sealed with installation foam;
• Now you can put the floorboards back.

Lining inside

Insulation of the veranda can be done both from the street and from the inside. With insulation on both sides, it will be possible to achieve an incredible level of protection for the terrace during winter frosts, retaining much more heat.

1. Initially, all existing cracks are sealed.
2. Then you need to build a frame from a wooden beam.
3. Next, a special waterproofing film is attached to the beam. It is better to install it from the inside using a construction stapler, thanks to which the process will take less time and will be much more convenient.
4. After these procedures, a frame is constructed from timber or a metal profile, which is filled with foam plastic or other similar material. It is desirable that the distance between the metal profiles correspond to the width of the insulation itself.
5. Drywall is installed on top of the frame.
6. The final stage is plastering, painting or installing artificial covering on the surface of the walls.

Ceiling insulation

To achieve an effective level of insulation of the veranda, the ceiling of the room must also be insulated. This procedure is quite labor-intensive. For high-quality work done, you should initially decide on the insulation and application or installation technology.

Thermal insulation of the ceiling in the attic is mainly carried out during the construction of the terrace, but if it was not there initially, then it can be built some time later. Sheets of polystyrene foam or other insulating material and vapor barrier are placed into the rafter frame.

It will be a little more difficult to insulate the terrace from the inside. The thermal insulation process can be done in one of several ways.

First way:

1. First, a frame of 3x3 cm beams is built on the ceiling.
2. Insulation material with a similar thickness is placed into the resulting cells.
3. Afterwards the ceiling is covered with plasterboard.
4. The final stage is painting or plastering the surface.

Second way:

1. Instead of the old ceiling covering, OSB or plywood is laid.
2. Behind this is a film for waterproofing.
3. A frame is constructed from beams in which mineral wool, polystyrene foam or another type of insulation is placed.
4. At the end, the constructed structure of beams is covered with film, on top of which the lining is hammered.

Third way

• The third method is the easiest. Frameless insulation is carried out only using solid material.
• Sheets of foam plastic are fixed on the ceiling itself without any specially equipped structures.
• Next, a construction mesh is placed on the ceiling, which is covered with putty.

Large-scale work on arranging a warm veranda

When insulating a veranda, you cannot get by with insulating the walls alone. We have to work on the floor, the ceiling, the windows, and the door.

Let's start with the windows

Any insulation begins with windows. Usually the veranda has a very large glazing area. If the windows are old, the frames are dry and do not retain heat well, the windows will have to be completely replaced

It doesn’t matter whether the new windows are wooden, plastic or aluminum

All these types are capable of retaining heat inside the veranda, the main thing is that there are no gaps in them. In an unheated veranda, you can make windows with single glazing, but if you plan to heat it, you will have to spend money on double glazed windows.

The veranda has a large glazing area, so the windows must be of high quality

Working with walls

At this stage you need to decide on the insulation. The industry produces enough types; almost any type will do for insulating a veranda. However, in addition to the advantages, each material also has disadvantages that must also be taken into account.

The main thing you need to pay attention to is fire safety, since the veranda is a lightweight building, and besides, a summer kitchen is often placed on it. We list the main types of insulation

The warm veranda is comfortable and cozy at any time of the year

Sheets of insulation are attached to the walls with dowels with large diameter caps. To prevent the caps from sinking into the insulation, place thin wooden plates on top of the insulation at the attachment point. The cracks in the joints of the insulation need to be “blown out” with polyurethane foam. A block is placed on top of the insulation, to which decorating material, such as lining, is attached.

We continue work: floor and ceiling

Ideal if you can make a concrete screed. If not, at least cover the plank floor with linoleum or carpet. It would be more effective to make a double floor: a rough floor made of unedged boards is laid on the joists, any insulation is placed on top, then the finished floor, leaving a gap of 1-2 centimeters between it and the insulation.

Isn’t it a pity to leave such a corner “to be devoured” by the winter frosts?

Use any available insulation, such as mineral wool. Glass wool is undesirable, since it absorbs water well and at the same time becomes very heavy.

A layer of waterproofing is made between the insulation and the roofing material. If you don’t do this, you will end up with damp and ineffective insulation. Compared to industrial insulation, using expanded clay, soil, and sawdust for roof insulation is ineffective.

Warming thin film (thickness 0.4 mm) - an infrared film heater that converts electrical energy into heat: like the sun's rays, such a film heats not the air, but objects located in its area of ​​​​action

We insulate the doors

First of all, you need to insulate the door frame so that drafts do not penetrate into the cracks. The easiest way to do this is to glue a seal around its perimeter. A tubular rubber seal on a self-adhesive base is suitable. If the door frame is rotten, it will have to be replaced.

The door leaf can be insulated by covering it with batting or other soft insulation. Remove the fabric from the loops and lay it horizontally.

First, make protruding rollers around the perimeter from the outside, which will become an additional barrier to drafts. Then attach the insulation to the entire door leaf, nailing it in with nails or a furniture stapler. The top can be upholstered with dermantine.

Insulating the veranda greatly expands the possibilities of its use

Insulating the veranda will make it suitable for year-round comfortable recreation. There is no need to install a heater on it, except for the coldest days of winter. But if you still have to do this, then a few hours will be enough, and the air temperature will allow you to be on the veranda without outer clothing. Published by econet.ru

Insulation of veranda windows

Among other things, such windows will isolate the veranda from noise. Installing plastic windows is not a simple matter, however, 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.

But even if you do not plan to change the single-glazed frames on your veranda, you can somewhat reduce heat loss by using heat-saving films. They can only be used in winter (from October to March), but in the autumn-spring season they can, to some extent, smooth out temperature changes outside and inside the veranda.

The heat-saving film is mounted on double-sided tape glued around the perimeter of the veranda frame and, after gluing, is treated with hot air from a household hair dryer.

Thanks to its ability to reflect up to 30% of infrared radiation tending to leave the room, it is almost equivalent to second glazing.

Therefore, it is better to insulate the veranda from the outside. In this case, the dew point should theoretically move into the insulation and the walls will last longer.

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

In this case, the best option would be to install a modern front door. It was originally designed to retain heat in the room:

• Companies that produce and install metal entrance doors usually have several models in their catalog intended for installation in a private home.
• If you want to avoid additional expenses, you need to insulate the structure yourself. For example, it can be covered with felt or an old stuffed blanket.
• It is better to cover the structure, both from the outside and from the inside.
• In order for the door to look aesthetically pleasing, a leather substitute, matting and other materials are mounted on top of the insulation.
• Self-adhesive rubber seals must be installed around the perimeter of the door.
• If you want to radically solve the problem of how to insulate a summer veranda, install a second internal one, this will create an additional air gap.
• After completing the work, you can begin finishing the room and continue to use it in the winter.

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! Old windows need to be removed and good, high-quality windows installed that will retain heat in the veranda

Options for heating a closed veranda in winter

Having answered the question of how to make a warm veranda with your own hands, let's look at the most popular and affordable options for heating a closed veranda in winter.

• Fireplaces and stoves. They are an ideal option if you don’t want to bother with laying pipes and electrics. This is one of the most economical heating options. The disadvantage of this type of heating is the need to constantly monitor the maintenance of heat. This is the most fire-hazardous type of heating, so take measures to protect the floor and walls of the veranda from contact with fire.
• Heaters. Today, manufacturers offer a huge selection of heating devices: wall-mounted and floor heaters, radiators and air heaters, “warm floors,” IR and UV emitters. For a well-insulated veranda, one or two heaters are enough. They can be set at any time to temperature maintenance mode or automatic shutdown when a certain temperature is reached in the veranda room.

• Climate control. You can find a huge selection of climate control equipment on sale. Such systems allow not only heating, but also cooling the air in the room. The climate control system cannot be used in winter as a full-fledged heating source on the veranda.

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 the walls and the 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.

External or internal insulation

For interior work, choose a material that allows steam to pass through well

To insulate the veranda of a house for winter living from the inside with your own hands, experts advise choosing the most practical method. External insulation has many more advantages compared to internal insulation. If we are talking about installing insulation inside, the freezing point can move into the wall, which ultimately causes its destruction. With the external method, the walls are strengthened and accumulate heat. It also allows you to save the area of ​​the veranda and not waste time dismantling the finishing. There are many options for exterior insulation, depending on the material, budget and climate conditions.

Insulation for attic and roof

PPU is sprayed using a compressor.

Unlike the floor, insulating the attic floor and roof is a very important procedure, because warm air rises and looks for a way out. Before insulating the veranda from the inside, take into account the fact that there is a lot of moisture in the warm air, so the thermal insulation must be protected with a special film. The only material that does not require additional waterproofing is liquid polyurethane foam and penoizol. Scheme of attic floor insulation, starting from the inside:

• ceiling;
• hydrobarrier;
• insulation.

Insulating a roof with mineral wool is somewhat more complicated. Thermal insulation is laid between the rafters. How to properly insulate a veranda, layers from the inside:

• vapor barrier – protection from steam and water;
• mineral wool;
• hydrobarrier – protection only from water;
• ventilated gap;
• roof finishing.

During installation, mistakes are often made when laying films. Some people put it on the wrong side, and the membrane allows steam to pass in the opposite direction, that is, into the thermal insulation. As a result, the movement of moisture is disrupted and the insulation rots. This result is also achieved by using vapor barriers over the insulation instead of vapor-permeable waterproofing. If penoizol or polyurethane foam is used as thermal insulation, then it all comes down to spraying the material directly onto the rafters.

Based on the results of our article, we are once again convinced of the versatility of liquid thermal insulation, which, along with its excellent characteristics, makes this material a leader in its cohort. Insulating the veranda with polystyrene foam is allowed; this is probably the most budget option, but this material does not breathe at all, which is detrimental to wood.

How to properly insulate a veranda

A veranda is a room attached to the house, open or glazed. It is most often a place of rest, but can also be used for various household needs. Thoughts about how to insulate a veranda sooner or later come to every homeowner.

It’s pleasant to relax on the veranda, because on the one hand you feel close to nature and breathe fresh air, and on the other hand you are in comfortable, almost homely conditions. Summer relaxation on the veranda is wonderful - the breeze flies in through the open windows, and the ceiling saves you from the burning rays of the sun.

It’s no less pleasant to be here in the fall, when the rain drums on the roof, and you can, wrapped in a blanket, snooze comfortably in a rocking chair. But then winter comes. And how nice it would be to sit on a frosty, fresh day on a veranda filled with bright winter sun and admire the snow-covered landscapes!

But the wind sweeps snow into the cracks, drafts instantly blow heat from the veranda and the heater becomes useless. Then the question arises about insulating the veranda.

What to cook

Naturally, the basis of everything will be insulation. The choice here is not particularly large - polystyrene foam with expanded polystyrene, mineral wool or penofol. The latter should not be used independently if you need high-quality insulation - it works well only in conjunction with a more solid thermal insulator.

If the choice falls on cotton wool insulation, then you should prepare in advance not only them, but also films for waterproofing, as well as a vapor barrier. They will be necessary - cotton materials easily pick up water from the air and as a result of leaks from the roof, which means they lose their effectiveness and become unusable. Foam blocks do not need such protection. Despite the higher cost and more complex installation process, when choosing how to insulate a roof here, it is better to give preference to cotton wool - it is more effective and not completely safe, which cannot be said about polystyrene foam.

The tools you will need are the most common: a tape measure, a hacksaw, a screwdriver, a hammer and others that you have in your pantry and will facilitate all operations. In any case, even a novice master has almost everything. It is worth preparing additional gloves, a protective suit or clothing that covers the skin completely - small particles may fall out of the cotton wool, causing irritation. Goggles to protect your eyes are also required.

Preparatory activities

Preparation consists of studying theoretical information if there is no experience in such work. First you need to buy all the materials, prepare the tools, think over the plan. If the veranda is not new, the decorative trim should be removed.

Required Tools

No specific devices are required to insulate the terrace. You can get by with what the home handyman has.

You will need:

• construction knife;
• stapler;
• roller and brushes;
• screwdriver;
• hacksaw.

In addition to insulating material, you need to buy:

• polyurethane foam;
• self-tapping screws;
• gypsum;
• vapor barrier;
• wooden beam;
• tow or jute for caulking.

Tools necessary for the work.

Materials for thermal insulation of verandas

The veranda in a wooden house is also, as a rule, made of wood. Despite the fact that the construction market provides a wide selection of thermal insulation materials, not every insulation is suitable for the walls of a log and timber house

When choosing a material, you must first pay attention to such characteristics as thermal conductivity, water resistance, fire resistance

The following materials are usually used as thermal insulators for finishing verandas:

• mineral wool;
• Styrofoam;
• EPPS;
• PPU;
• Penofol;

Minvata

Traditional insulation for wooden structures is mineral wool. It has low thermal conductivity, is non-flammable, has high soundproofing qualities, and is considered an environmentally friendly material. Although many experts question the latter, since mineral wool uses harmful resins as binding components. In addition, the insulator strongly absorbs and accumulates moisture, which affects its thermal insulation properties. You can read more about the characteristics of the material in the article: “Features of external insulation of a house with mineral wool.”

Styrofoam

One of the most popular and inexpensive materials is polystyrene foam. The insulation shows itself to be an excellent heat insulator, is moisture-proof, biologically stable, weighs little and is easy to install. However, foam insulation has a number of disadvantages: the material is flammable, releases harmful volatile compounds when ignited, is not durable, and has low vapor permeability. In this regard, polystyrene foam is not recommended for use inside the house.

Extruded polystyrene foam

Extruded polystyrene foam is an excellent heat insulator. In many respects, it is much more effective than polystyrene foam, although it is more expensive. The thermal conductivity and water absorption of EPS is lower than that of polystyrene foam; it is resistant to solvents, durable and heat-resistant. However, the material does not withstand UV radiation, under the influence of which it loses its characteristics. This can be easily avoided if you immediately cover the insulation with cladding.

Polyurethane foam (PPU)

Available in the form of panels and polyurethane foam. The second option is more popular. Foam insulation copes with its tasks perfectly, filling even the smallest cracks and cracks. Insulation with polyurethane foam is carried out by spraying using a special installation. Therefore, in this case, you cannot do without the help of specialists.

Penofol

One side of the insulation is covered with foil, which reflects the cold air coming from the street and at the same time retains heat inside the veranda. Thermal insulation with penofol can be chosen as the main insulation, but the material has shown the greatest effectiveness when combined with other insulation.

Natural and synthetic materials for caulking

Moss, tow, and flax batting are inexpensive insulation materials used for caulking inter-crown seams and joints. They are made from natural materials and do not violate the environmental friendliness of a wooden house. Available in the form of tapes, ropes, ropes. However, birds love natural insulation materials, so additional treatment with special means is required. In addition, working with these materials requires certain experience and skills.

Polytherm is a special synthetic insulation made from polyester fibers. The threads are fastened by soldering without the use of glue. The material is produced in the form of tapes, completely ready for use.

Review of thermal insulation materials

What properties do heat insulators have?

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

Most wood-based products, such as MDF, plywood, and fiberboard, also have low thermal conductivity. Therefore, wooden doors, MDF wall decoration, and lining the attic hatch with clapboard help 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-toxicity, antifungal (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 extruded polystyrene, is an inexpensive, fairly durable thermal insulator, the main disadvantage of which is its high fire hazard. When burned, it releases toxic substances. They produce modified self-extinguishing polystyrene foam with fire retardants (marked “C”). Fire-resistant boards are much denser and heavier than the types of polystyrene used for packaging. Extruded polystyrene foam 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 by mixing chemicals. When hardened, it “locks” in tiny pockets of air. Since foam can fill cracks and crevices, it is used to seal existing building structures, which helps eliminate drafts. Foam adhesive tapes are used to insulate windows, doors, and 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

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

Thermal conductivity of the panels is 0.007W/(m•K). In terms of thickness/degree of thermal insulation ratio, this is the best of all available materials for insulation. VIP systems 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 the optimal layout 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

Insulation technology

Since it is easier to insulate an extension to a house from the inside - you can work in any weather - this method, despite all its shortcomings, is used quite often. Another reason for this choice is often related to the fact that the external walls are already finished with the same facade material as the entire house, and you do not want to spoil the exterior.

There is no big difference in how to attach the insulation - from the inside or outside. There are serious differences only in the thermal insulation technologies of different structural elements.

Walls

The method of installing insulation is selected taking into account its type and subsequent finishing:

If you plan to plaster internal or external walls, then this can only be done using expanded polystyrene and mineral wool with a density of at least 130 kg/m3. They are glued to the surface or mounted end-to-end using umbrella dowels with a large head.

The question of how to insulate a veranda for winter living with walls decorated with cladding panels is resolved in a completely different way. To attach them, it is necessary to mount the sheathing, and the distance between adjacent guides must correspond to the width of the roll or slab heat insulator. If it is a non-moisture-resistant material, then it is covered on both sides with a breathable film to insulate it from the penetration of wet steam from the room and precipitation from the street. A ventilation gap is left between the insulation and the cladding, for which additional slats are placed on the sheathing.

Thermal insulation system structure

In order to efficiently insulate a wooden house, prevent the appearance of condensation on the surface and inside the insulation, and also prevent the formation of dampness, the best option would be to install a ventilated facade.

Regardless of what material is used, the structure is multilayer and consists of the following elements:

1. Load-bearing wooden wall.
2. Wooden or metal sheathing.
3. Insulation.
4. Windproof membrane.
5. A frame for finishing, which also allows you to form a ventilation gap between the finishing and the insulation.
6. Exterior finishing.

Floors

If the height of the room allows or there is no other way, then the existing flooring is used as a subfloor. Most often these are boards laid on joists. A beam is attached to them in a similar way to a frame for walls. But it must have a sufficient cross-section to withstand the loads. Insulation is laid between the new joists, covered with waterproofing and a finishing floor is installed.

If the base is concrete, one of the insulation options could be a screed with expanded clay or a heated floor poured into a regular concrete screed. This method is especially relevant when you need to decide how to insulate the veranda and make a bathroom or kitchen there by tiling the floors.

When the floor is accessible from below, the insulation can be secured under the existing flooring, creating the same thermal insulation pie, protected from moisture.

If the distance from the floor to the ground is very small, you can remove the flooring, fill the cavity with expanded clay and put it back in place.

To prevent the insulation from absorbing water from the ground, install a waterproofing barrier made of roofing felt or thick film. Source ekouteplenie.ru

Ceiling

The easiest way is to insulate the ceiling, which is accessible from the attic. If it is not there, then to maintain the height of the room, remove the roof and install thermal insulation.

When the ceiling height allows it to be reduced, the insulation is attached according to the already described scheme, as on the walls.

Windows and doors

The ideal way to eliminate heat loss through openings is to install double or triple glazed windows and an insulated entrance door. If there is no money left for this, there is another way to insulate a veranda in a private house cheaply with your own hands. During the cold period, the outside of the windows is covered with transparent film, the gaps between the frame and the wall are caulked and sealed with strips of paper or self-adhesive foam.

This is a completely acceptable temporary option for maintaining heat in a room. If you arrange a vestibule in front of the front door, installing an insulated frame partition, then the problem of cutting off the cold from it will be solved.

Knowing how to insulate a veranda in a wooden house with your own hands, you can turn it into an additional bedroom, kitchen or bathroom, expanding the living space of the house. To do this, you need to block the possibility of warm air leaving the room from all sides: through the floor, ceiling, walls, windows and doors. You can insulate both from the inside and outside, choosing the method that requires less cost or will be the most effective in your case.

Eliminate leakage of warm air through the ceiling

It remains to figure out how to insulate the ceiling, because a significant part of the heat evaporates from the wooden veranda through it. Especially if the front door opens. The flow of cold air rushing inward instantly squeezes the warm air upward.

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

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

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

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

If you want to ensure a comfortable air temperature inside the veranda even in the coldest time of the year, you need to take care of high-quality insulation of the extension.

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

We insulate the floor in the veranda

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

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

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

Which side to insulate the veranda from inside or outside?

After the floors are insulated, the verandas move to the walls. The same mineral wool or polystyrene foam is used as insulation.

It should be noted right away that only walls in contact with the street from the outside are subject to insulation. There is no need to insulate the internal partitions of the house. The photo shows a diagram of a wall with insulation. On it you can see the order of all layers.

Adhering to this scheme, we begin to insulate the walls internally. First, the entire surface is covered with waterproofing. The material at the joints is securely glued with tape to avoid the formation of gaps. The sheathing is knocked down to fit the size of the insulation from the bars. Thermal insulation is tightly laid inside each cell, the whole thing is covered with a vapor barrier film, after which the entire pie is sheathed with clapboard or plywood.

With a sound assessment of the total scope of work and the required costs. In terms of planning your own time and effort, unfinished repairs are worse than the premises in their original, “pre-repair” state. After measuring the surface of the floor, walls and ceiling, you need to choose your insulation option (foam plastic, thermal insulation rolls, mineral wool, a combination of these materials) and immediately buy them in the required quantity.

In addition, you will need consumables - bars and slats of various sections, nails, moisture-resistant film, glue, polyurethane foam, etc. Purchasing everything you need in advance will help you plan your expenses wisely and not be distracted by trips to hardware stores instead of work.

Insulation of a cold veranda begins with the choice of insulation and its installation location. As a rule, the veranda has a beautiful external and internal decoration. And deciding which side to hide under the insulation is not easy.

Insulation of a cold veranda begins with the choice of insulation and its installation location. As a rule, the veranda has a beautiful external and internal decoration. And deciding which side to hide under the insulation is not easy.

To make a final and informed choice, we offer arguments in favor of one or another type of insulation.

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

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

Let's decide how to properly insulate the veranda to the house with our own hands. Projects and photos will allow you to turn it into a full-fledged living space for the winter. You can use it absolutely at any time of the year. Before starting work, you need to think through absolutely all the nuances: insulation option, material for thermal insulation, places for installing insulation. In this case, it is possible to lay insulation from the inside and outside.

Insulating a veranda in a wooden house is possible subject to the following conditions:

• Installation is only possible if there is good ventilation.
• In cool weather, the heating should always be on in the veranda.
• Additional wall insulation cannot exceed a thickness of 55 mm.

• work is carried out outside the home, all garbage remains outside;
• repair measures do not make serious changes to the lifestyle of the inhabitants of the house;
• the area of ​​the terrace is not reduced;
• walls finished with special materials accumulate heat well and do not become damp, which increases the service life of the veranda.

Internal insulation can be carried out in any weather outside

In one approach, it is quite possible to protect all surfaces of the veranda (floor, ceiling, wall) from heat loss. At the same time, the home craftsman has free access to these bases at any height. But when performing interior work, you need to immediately prepare for changes in everyday life (especially when insulation is delayed for a long time) and the existing interior.

Actually putting it all together

Since the roof of the veranda will have to be insulated either with polystyrene slabs with foam plastic or with mineral wool, you need to create a base for them if there is no space in the rafter system or there are no rafters at all and the roof is laid on slats. Without lathing, there will be nowhere to lay sheets of expanded polystyrene, and there will simply be nothing to attach cotton insulation materials to. Need a frame. This structure is easy to assemble: slats or bars are placed on supporting structures in increments equal to or slightly smaller than the size of the mineral wool slabs. If polystyrene foam is used, the dimension must correspond to the dimensions of the insulation boards. The cotton wool must also be secured from below, using stretched cords or slats of wood. The frame can also be assembled from metal parts used in structures with plasterboard. Materials like penofol are attached directly to the ceiling using a construction stapler.

When the insulation is in place, it is lined with a vapor barrier from below - for mineral wool, or simply assembled decorative sheathing, as is the case with expanded polystyrene. At this point, all work is completed and you can enjoy the result.

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:

1. The first step is to get rid of all the cracks.
2. Next, you must make a sheathing or frame from wooden blocks. The fastening pitch is selected according to the width of the insulation, and the height depends on the thickness of the insulation.
3. When the vertical sheathing is ready, insulation begins to be laid in the free space.
4. Using a construction stapler, the insulation is sewn with a vapor barrier film. The film is fixed with an overlap of 10–15 cm.
5. Finally, you need to do the finishing. This can be covered with clapboard, plastic panels, plasterboard with wallpaper, painting or putty. It all depends on your desire.

Note! External insulation is performed in the same way. Only the finishing material should not be afraid of moisture and external influences

This could be facade paint or plaster, bark beetle, siding.

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

We install thermal protection for the walls

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

a) For wooden walls:

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

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

b) For block walls:

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

Select an adhesive composition specifically for laying polystyrene foam boards

All layers of the insulation cake are hidden under decorative plaster

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

Work progress:

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

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