Insulation of the inner wall of the balcony. Internal insulation of the walls of the loggia: which material is more reliable

Having carried out the insulation of the balcony, you can achieve 2 goals at once: to expand the living space and improve the degree of thermal insulation of the apartment. It is most correct to make external insulation, but here you cannot do without the services of industrial climbers and the corresponding costs. Insulating a balcony from the inside will be much cheaper, especially if you do it yourself.

How to insulate the balcony inside

An equally comfortable temperature inside the room and the adjacent balcony is considered a positive result of the work performed. It makes no sense to invest effort and money in insulation that does not protect against the penetration of cold onto the balcony and forcing you to tightly close the doors leading to the loggia in winter.

As a rule, for internal insulation of balconies it is used:

foamed polystyrene with a density of 25-35 kg / m 3, otherwise - foam;
based on basalt fiber 80-110 kg / m 3 density;
extruded polystyrene foam (one of its varieties -).

Note! For additional thermal insulation, thin foil insulation made of polyethylene foam - Izolon or Penofol is often laid on the main layer.

In addition to the listed insulators, there is another insulating material - ecowool made from cellulose waste. Simply put - waste paper. The rules for handling it and the installation technology are the same as with basalt wool. Ecowool is not very popular due to its high cost.

Brief characteristics of heaters

Styrofoam is the most cheap stuff for insulation, produced in the form of plates of various thicknesses.

Like all foamed polymers, it repels moisture well and has sufficient strength (at a specified density). It is characterized by high resistance to heat transfer and flammability, which is why it requires protection from accidental sparks.

The thickness of the foam for the insulation of the balcony in northern regions should be at least 100 mm, in the south, 50 mm may be enough.

Unlike foam, mineral wool does not burn absolutely, but it is capable of absorbing moisture, after which its thermal conductivity rises sharply. The problem is solved with protective layers from special films, which will be discussed below.

The heat transfer resistance of the mineral wool is not too high, therefore it is pointless to use material less than 80 mm thick. Insulation is offered in rolls and plates, and at a price it will cost more than polystyrene.

Advice! Do not insulate the balcony with fiberglass wool (glass wool) intended for outdoor or roofing works... The use of such materials inside residential premises is unacceptable.

The best option for internal insulation of the balcony is extruded polystyrene foam, sold in slabs.

Expanded polystyrene is durable, lightweight and has the best thermal insulation properties.

Where you need to lay mineral wool 100 mm in thickness, 50 mm of foam is enough.

In addition, the polymer is absolutely impervious to moisture and is so durable that the plate can be screwed on with self-tapping screws if necessary. There is only one drawback - the high price of the material, which is compensated by the long service life of the material - up to 50 years.

Balcony insulation technology from the inside

It is necessary to carefully prepare for thermal insulation on the balcony. This includes not only the acquisition of materials and the preparation of tools, but also the implementation of a number of preliminary works:

Reliable parapet device. There are 2 types of structures in practice: a welded metal frame with attachment to the wall or a masonry made of foam blocks. How to strengthen the parapet -.
... Sometimes the balcony is made panoramic by installing metal-plastic blocks to the full height, without a parapet. Then it will be necessary to insulate only the floors and the ceiling.
Elimination of all cracks and leaks leading to the street, removal of excess polyurethane foam.
pad electrical wiring for lighting, as well as drainage and highways with freon k (if any).

Before insulating the balcony inside, you need to level all surfaces by removing obvious influxes or filling up cavities and cracks with a solution.

Interior wall decoration

Do-it-yourself balcony wall insulation technology depends on the design of the parapet and the applied thermal insulation material. Metal carcass, finished with plastic on the outside, or, it is better to sheathe with 2 layers of thermal insulation in such a way that the second row of insulation overlaps everything metal racks, which are bridges of cold. Moreover, with outside, between the cladding and the insulation, a windproof film should be laid.

When insulating a balcony with mineral wool, it is necessary to use not an ordinary film, but a diffusion membrane as wind protection. It will let out moisture that occurs in the thickness of the cotton wool, but will not let it get wet from precipitation or fog outside. For polystyrene and polystyrene foam, the use of a membrane is not necessary, an ordinary film is also suitable.

To fasten the mineral wool, you will need to assemble an additional wooden frame made of beams with your own hands, whose width is equal to the thickness of the insulation. The step between the bars is selected according to the width of the material, the last one is inserted between them by a swath. At the last stage thermal insulation layer covered with a vapor barrier film, after which the frame is sewn up with clapboard or drywall.

Ceiling sheathing

And the balcony ceiling can be insulated in 3 ways:

If you plan to do at the end or pasting with wallpaper, then the method of gluing plate insulation is suitable building mixture... Warming, accompanied by "wet" processes, is carried out only in the warm season at positive temperatures.
For or similar finishing will have to be attached to walls and ceilings wooden blocks, and roll or slab material lay between them.
When insulating with expanded polystyrene, the plates can be directly attached to the walls and ceiling with dowels. After that, the surfaces are leveled with putty and painted, or a crate is placed by fixing the bars to the foam blocks or concrete through the insulation. Lining, plastic, drywall and other finishes to choose from are easily attached to the crate.

Note! For fastening the battens to concrete ceiling through expanded polystyrene it is necessary to use special screws for concrete - frame pins.

When insulating a balcony mineral wool without timber frame not enough. Cotton wool can be glued, but it is quite difficult. The best option is to insert it between the beams attached to the wall and ceiling, protect it with a vapor barrier and revet it with a suitable material.

The method of gluing is convenient when working with polystyrene, but after 2 days it is necessary to additionally fix it with dowel-umbrellas and apply a plaster layer over the fiberglass mesh.

Floor insulation

The technology of thermal insulation of balcony floors differs from walls and ceilings, since the “cake” of insulation must bear certain dynamic loads and have a flat surface. Leveling is done by laying wooden logs, between which insulation is laid, and on top is laid finish coating... The sequence of actions is as follows:

Cut the wooden beam into crossbars along the width of the balcony and fix them to the floor with anchors or self-tapping screws and dowels using steel corners.
Fasten 3 longitudinal lugs to the crossbars with self-tapping screws. In the process, they must be aligned horizontally, starting from the highest point. Using building level, the beams at the intersection with the crossbars should be lifted and plastic or wooden wedges should be placed.
Place the insulation tightly between the crossbars and the lag. In the case of mineral wool, laying a vapor barrier on top of it is mandatory.
Install the floor covering with fixing to the joists.

It is characteristic that the length of the crossbars and the lag does not need to be adjusted to the dimensions of the balcony. It would be more correct to make them shorter by 10-20 mm, so that the ends do not rest against the walls. Wood tends to "breathe" and deform a little; with a tight fit, the floor surface can later bend into an arc.

Moreover, walking on such floors will be accompanied by an annoying creak. The resulting gaps near the walls will hide under the flooring and will not be visible.

When using slab insulation, it is worth choosing the right step of the crossbars so that you do not have to cut the slabs again. Standard width- 600 mm, and you need to be guided by it. After laying the polystyrene or expanded polystyrene, all joints and cracks must be filled with polyurethane foam.

Helpful instructional video:

Mineral wool is protected with a vapor barrier as tightly as possible so that moisture from inside the room cannot seep into it. Here, too, you can use polyethylene foam like Penofol, but pay Special attention gluing joints.

If you seriously and scrupulously approach the procedure for the internal insulation of the balcony, then it is not at all necessary to hire craftsmen and pay them money, which is never superfluous. You will spend twice as much time to complete the work, but you will do everything efficiently and in accordance with your personal wishes. In addition, you will save money on your family budget.

The loggia could well be called an additional room in the apartment, but, unfortunately, many use it only in the summer, since it initially does not have insulation, and no heating batteries are brought out there.

Modern way insulation - spraying polyurethane foam

Polyurethane foam is sprayed onto the walls using special equipment, and specialized companies are engaged in such insulation.

However, before inviting them to spray such insulation, the walls must be prepared by making a crate on them. It will be a kind of frame for a sprayed and expanding heat insulator, as well as for fixing decorative finishing material.

The advantage of this method of insulation is that when spraying, the material expands and closes all the cracks, making the surface absolutely not blown through, without cold bridges. Polyurethane foam covers not only the walls, but also the ceiling and floor.

Loggia design solutions

I would like to show several options. Perhaps by starting the process of converting a cold room into a usable area, someone will be inspired by one of the ideas developed by the designers.

In this case, a standard loggia with a small footage is presented, transformed into cozy room recreation. Here you can retire with a book or laptop and delve into reading. If a large family lives in an apartment, usually each of its members does what they love, and sometimes it is difficult to find a cozy place to sit in silence. The insulated loggia will be an ideal option for this.

In such a room, you can place a small TV and enjoy your favorite programs or sit with handicrafts, comfortably picking up on comfortable armchair legs. The main thing is that there is extra space that can serve all family members in turn for doing what they love.

Original version- the loggia turns into a stylish bar

This option is suitable for apartments in which the door to the loggia is located in the kitchen. In this case, it can become a dining room, especially since mostly kitchens in apartments are quite small.

If the apartment owners like to hold parties often, the loggia window sill can easily replace the bar counter.

You can also arrange a romantic dinner here. The evening city, which offers a wonderful view, and the pleasant summer air will create the necessary mood for this. In winter, it's nice to sit at the counter, sipping coffee and looking at the opening wide panorama outside the window.

Glass sliding doors installed between the kitchen and the loggia will help to combine or delimit the premises, depending on the need.

In this version, it was combined with the living room, and the wall, which previously served as a dividing element between the two rooms, became unifying, as it was transformed into a comfortable table.

The area of the former loggia in such a layout can be used as an office with a convenient writing desk, as well as hobbies when you don't want someone to interfere.

And, of course, combining the loggia and the room will increase the overall space by opening big window... The room will be more illuminated, which will help save energy costs.

Additional living space can be adapted to various activities, for example, done on a loggia winter Garden, workshop or computer room. Therefore, if the apartment is equipped with a loggia, but it is not yet insulated, you urgently need to get down to business and expand the area of your home due to the functionally unused premises.

Hide

Insulation of cold glazing is sometimes used, although usually this activity takes a lot of time and effort, but does not give the desired result, since in most cases it is carried out incorrectly. Before work, you should learn how to correctly insulate a balcony, making it a comfortable room.

What kind of glazing is considered cold?

Quite often, when purchasing an apartment, the owner is faced with what she already has. Often, the developer does not apply expensive materials and installs cold glazing without insulating the balcony in any way. In this case, replacement of cold glazing with warm glazing may be relevant. , which will significantly improve the final result, as it will help eliminate heat loss that occurs precisely through the window frames.

However, you can improve and. Most often, aluminum frames act as it. Aluminum itself has a high thermal conductivity, so the room cools down quickly. It can be cold and plastic double-glazed windows... Most often this is a problem of single-chamber designs. This type of glazing can protect against precipitation, wind, dust, but it does not resist frost well. Therefore, the insulation of the cold glazing of the loggia or balcony plays quite important role to create a comfortable atmosphere in the home.

How to insulate a balcony with cold glazing?

How are the glass replacement works carried out?

Any work is carried out in several stages. This procedure is performed like this:

Calculation of the mass that the parapet can withstand. Glazing that is too heavy must not be used, as this can lead to the collapse of the structure.
It is quite easy to remove cold windows: this will require cutting off the foam, pulling out the glass, disconnecting other fasteners, if any. The frame can then be pulled out.
New windows are being installed. It is recommended to use plastic with double glazing. They usually do not weigh very much, while retaining heat well.
If you had panoramic cold glazing, then you can install plastic windows from the floor or build a parapet from lightweight materials, such as a gas block.
You can choose any windows according to the method of opening, it only depends on how much free space is on your balcony.
If you cannot install windows with a thick glass unit, you can put energy-saving glass on a thin one, they will help keep warm, while not increasing the mass of the structure.

Replacing the building is technically simpler and does not require special permits, therefore it is recommended to change the glazing to the same as it was in shape, with the only difference that a warm structure will be used. After the installation is done, you need to install glazing beads on the glass, adjust the fittings.

Insulation of cold glazing and its subsequent replacement with warm one is a waste of effort and money, since when dismantling old structures and installing new ones, the tightness will be broken. The finish can also be damaged, new cracks will appear in the seams. If you plan to do warm balcony, it is recommended to start work with the replacement of glazing, and then carry out work on the insulation of structures. They are made in the same way as when insulating cold glazing.

Cold glazing is mainly used to protect the balcony from precipitation and drafts, but even with proper insulation, it is not able to protect it from frost. If you plan to make the balcony really warm and significantly raise the temperature inside it, it is recommended to immediately replace the cold frames with warm ones.

Today's balcony in many apartments turns into a full-fledged room, functional space... This is especially true for small apartments, whose residents appreciate every centimeter. If the balcony is insulated, it becomes an office, a closet, a resting place, a mini greenhouse, a dining room or an extra bed. There are many options for using it. The main thing is to do the work on its insulation with high quality. Only in this case it will be warm and cozy on the balcony.

Features and Benefits

V warm time the whole family can rest on the balcony for years, but when autumn comes, this room becomes useless. If you insulate it, the situation will change. The plus is that all the planned work is easy to do on your own. Additionally warm room Is a space in which it is easy to create a small work or relaxation area. In addition, the presence of a warm balcony will automatically make the apartment cozier and warmer. You can attach a living room or kitchen to it, depending on its location. This will create extra space.

Before you start with insulation or glazing, you need to get expert advice. He will definitely tell you what kind of load a warm balcony can withstand, whether it is worth strengthening it. If the foundation is strong concrete slab, the question of amplification does not arise. But the metal parapet must be reinforced with foam blocks or light bricks from ceramic material... The same should be done in the case of a fragile fastening of a reinforced concrete base.

For insulation, double-glazed windows can be used wooden frames... They are environmentally friendly, allow windows to "breathe", but are expensive. Aluminum windows insulated with polyamide inlays increase the thermal insulation of the room. The most optimal would be the equipment of PVC windows with double glazing, which reliably retain heat.

Such windows are cheaper than wooden ones, but at the same time their thermal insulation is not inferior to aluminum ones.

What materials are better to choose

For finishing balconies or loggias today there are many varieties of finishing materials, with the help of which they give even the smallest room an original and attractive look. The main thing is to do right choice material for decoration. For insulation, experts recommend using cork, plastic panels, lining with wooden or plastic base, drywall, plaster, MDF panels, decorative rock, aluminum profile, penoplex, expanded polystyrene, penofol.

Mineral wool, styrofoam finishing - perfect solution for self-insulation rooms.

In the case of a non-insulated balcony, it is better to give preference artificial stone, plastic frost-resistant lining, cork panels or tiles. Most often used for finishing the following materials:

Drywall

This material differs in that it lacks toxic substances, it is easy to process and in design is combined with other finishing materials. Drywall can be plastered, painted, wallpapered, sheathed with panels and clapboard. With this universal material just turn the balcony into a full-fledged living room.

PVC panels

A practical solution, but it is better not to use this material if the constant temperature on the balcony is below five degrees. This problem can be solved with the help of frost-resistant panels, developed using new technologies. This material is not afraid of moisture, but is able to quickly lose color from direct sunlight. This point should be taken into account if the room is located on the south side. Advantages: low cost, quick and easy installation with glue.

Cork panels

They create coziness that cannot be organized using other Decoration Materials... Cork panels are pressed bark of cork oak. Cork panels are easy to install and are suitable for any type of balcony, regardless of the room temperature. The cork panel does not absorb foreign odors, including the smell of tobacco. Lack of material - high price. For insulation, inexpensive penoplex is also used; mineral wool is also perfect.

How to properly insulate a balcony with your own hands: step by step instructions

A balcony in a city apartment is a special space. This piece of the house, brought out under the open sky, can become an office, a greenhouse or a resting corner, as long as it is glazed and insulated.

Do-it-yourself balcony insulation will save a lot of money. Sheathing in panel house, in "Khrushchev" is done taking into account the characteristics of the apartment and building.

Step 1... To begin with, the old frames are dismantled, the surface is prepared and things are taken out. Insulation from the inside - important stage the whole process.

Step 2... At the second stage, it is necessary to glaze the balcony. The best option there will be windows plastic pvc... Many people prefer to keep the old wood frames. However, remember that even if wooden structures in good condition, they will not be able to organize the same heat saving. There are cracks in the tree, so it makes no sense to engage in insulation in this situation.

Step 3... After the plastic windows are installed, you can begin to warm the floor. Be prepared for the floor to get higher. Consider this if the ceiling in the room is low.

Step 4... Wall cladding is carried out after the installation of windows and floor insulation. The walls on the balcony are side walls, except for capital. At the final stage of insulation, Finishing work... The choice of materials depends on the budget. In the process of finishing, window slopes opening onto a balcony.

Required tools and materials

In order to insulate a balcony or loggia, you will need the following tools: a hacksaw for metal or a clerical knife; roulette; level; pencil, marker or any other writing instrument; a tool for applying glue - a brush, a spatula, and so on; other instruments. From the materials you need glue and the insulation itself. In addition, you will need a vapor barrier film and a windproof membrane.

You will also need a frame device. In this case, you will need wooden beams as well as nails to secure them. You may also need special fasteners - nails with very wide heads. They are used when polystyrene is not attached with glue.

Insulation inside

High-quality thermal insulation combined with double glazing transforms the balcony into a living space. It is necessary to insulate not only the walls, but also the floor and ceiling. Insulation materials must be durable, lightweight, safe for humans. Due to precipitation and condensation, the walls of the balcony can become damp and moldy, which means that a hydro and vapor barrier is needed.

Polystyrene foam meets these requirements as much as possible: traditional foam and Penoplex thermal insulation boards. The first is very lightweight, compressive strength, waterproof. Penoplex is insulation made of extruded polystyrene foam. Its margin of safety and durability surpasses conventional foam, and its shape makes it easy to install in the grip and provides perfect insulation. Balcony cladding with slabs can be performed both inside and outside.

Warming closed balcony starts with surface preparation. It is necessary to carefully cover the gaps and joints between the floor, walls and parapet with polyurethane foam without toluene in the composition. Metal constructions need to be cleaned from rust, covered oil paint and treat with a building antiseptic.

Before installing the insulation, they put windows and doors. Window sills and slopes are mounted at the last stage of work. The glazing of the balcony depends on the parapet. If this is just a metal crate, it needs to be built up with ceramic (lightweight) bricks or foam blocks. The thickness should not exceed ten centimeters. To protect the foam blocks, at the finishing stage they are covered with corrugated board.

Floor

Window structures can be installed on a reinforced concrete parapet immediately using various assembly and sealing compounds. Metal-plastic windows have excellent characteristics, with skillful installation, they reliably protect the balcony and look aesthetically pleasing. When choosing a model, it is worth stopping at swing frames with double glazing.

Floor

In order to insulate the floor, you can resort to two different directions at once: to make it warm or to constantly warm it up. We are talking about installing a floor heating system, for example, an electric one. Installation of a water system on a balcony is very inconvenient and almost impossible, but installation of an electrical or film system is easy to carry out.

photos

It all starts with preparation. A waterproofing film is laid on the floor under the tiles, which protects the floor from moisture from the outside. Further, the crate is arranged. Instead of a lag, a bar is used, five centimeters thick. If you do not want to raise the floor too much in relation to the old coating, it is better to use a beam of low height. A square beam of 50 × 50 mm is perfect. The beams are laid every 40-60 cm.

To prevent moisture from entering the insulation from the inside, it is covered with a vapor barrier film. It is laid on top of the beams and attached to them with construction stapler... For internal fastening an attachment pitch of 50 cm is sufficient to avoid creating unnecessary holes in the film. Polystyrene must be protected from moisture on all sides. Therefore, it is better to lay the film with an overlap on the walls. All gaps between the beams and walls should be repaired with the same insulation material or polyurethane foam.

Walls

Many do not insulate the walls, believing that they do not receive cold from the side of the house on the balcony. In many ways it is, but the work needs to be done. The walls themselves are not sources of cold, but the joints between them and the side walls of the balcony can be. For this reason, the whole work can only consist in installing foam foam, which is vapor-tight and thin. It will protect the walls from icing and the penetration of condensate into the balcony.

Ceiling. If it comes about a private house, it is best to make a special roof structure. It is recommended to do pitched roof, the slope of which is directed away from the house. The roof is made of rafters and lathing. A waterproofing film is attached on top of it. They are attached to the film roofing material, and waterproofing on top of double-sided vapor barrier film with the absorbent side inward. From below, the rafters are hemmed with a vapor-permeable windproof membrane.

The floor slab, that is, the horizontal part, must have several layers at once: insulation; vapor barrier layer; load-bearing beams with interior decoration. The device begins with the installation of the frame, namely rafter system... Next, a vapor barrier double-sided membrane is attached to it in the specified way. Then they arrange a crate and lay a waterproofing layer. You can use classic roofing felt or special PVC films.

Insulation outside. In order to insulate the balcony from the outside on your own, skills are required. Do it yourself quality work, given the characteristics of the building is not easy. Finishing outside means saving up to thirty percent on heating. Remember that outdoor work is fraught with some difficulties: if the balcony is higher than the second floor, then industrial climbers will have to be involved in the work.

Before starting the insulation, obtain the consent of the officials from the architecture department. Appearance a balcony can ruin the overall picture, but if you finish in the same style as the entire building, then you can get permission. Outside insulation has a number of advantages:

the reinforced concrete slab remains warm, wet air from the room freely passes through it and is released into the atmosphere;
saving useful space;
you can install a layer of thermal insulation of any thickness, this will not affect the interior of the balcony in any way.

The materials can be used the same as for internal works... Preference is given to sprayed thermal insulation as the lightest and most effective. Experts recommend using polystyrene or expanded polystyrene. Mineral wool is sensitive to moisture penetration, so its installation requires special care and accuracy.

An independent procedure for insulating a balcony is difficult. All steps must be completed at high level otherwise the room will not be completely isolated. Glass, panoramic, stained glass balcony is an excellent solution for small space... Designers advise to connect it to the room for expansion. Glazed balcony connected to the kitchen on top floor Is a luxurious solution.

The balcony is a part of the building that needs insulation more than others, because not all residents use it only as a warehouse. Increasingly, people begin to equip their balconies for an additional room, for example, Personal Area... For these and not only reasons, it is necessary to produce competent insulation of the structure from the inside.

In this article, we will look at three methods using different materials.

Balcony insulation stages

Insulation of the balcony from the inside is performed in the following sequence:

# 1. Thermal insulation of a balcony with expanded polystyrene: a sequence of works

If you chose expanded polystyrene as a heater, then the sequence of work is as follows:

# 2. Balcony insulation with foam (video)

Penoplex is actively used in the insulation of premises. You can attach it to the surface using bituminous mastics, polyurethane foam or dowel-mushrooms. Consider the option of mounting on polyurethane foam.

Fastening to polyurethane foam

So. The waterproofing is done. The insulation plate is applied polyurethane foam around the perimeter. It's enough. After application, we wait a couple of seconds and fix the plate on the insulated surface. The next slab is stacked to the first end-to-end. After two days, you can fix the slabs with additional dowels. Further, the whole process is repeated in a similar order, which is described above. Finishing do it at your discretion. You can sew up the insulation plates with plastic panels, they look very original.

Additionally, we fix the slabs with dowels

Advice. If the balcony is intended only for storing essential things on it, then it is enough to insulate the walls in one layer. If you need to insulate more thoroughly, then it is better to lay the insulation in two layers.

The process of insulating the balcony has been completed. As you can see, it does not represent anything complicated. If you are just planning to do this work, then our article will help you. If you have already done this, share your methods with your readers in the comments.

No. 3. Thermal insulation of a balcony with mineral wool: technology features

Thermal insulation of balconies with mineral wool is carried out under the constructed lathing. A lining is attached on top of the frame - wooden or plastic panels with special grooves.

A well-known fact is the building recommendation to carry out insulation from the outside of the building. However, in the insulation of balconies and loggias, it is often impossible to arrange the insulation material outside. Internal placement of a layer of insulation requires certain calculations, adherence to technology and correct selection materials so that in the future the work performed does not lead to wetting of the walls, corners and ceiling inside the outrigger structure.

Thermal insulation of a balcony with mineral wool

What materials can be used to insulate the balcony and? What finish will allow you to reliably protect the insulation from the inner space and create aesthetic appearance interior walls?

V modern technologies insulation of open hinged structures(balconies) four types of material are used as internal insulation: polystyrene, penoplex, penofol and mineral wool. Consider technological features installation and types of wadded insulation used for thermal insulation of balconies.

Types of mineral wool

Depending on the raw materials used in the production, there are three main types of mineral wool: glass, stone and slag. All three materials are suitable for insulation work.

Minvata is soft material without rigid dimensions. It is supplied in the form of rolls (they are unwound into a track before laying) or soft mats. Sometimes one side of the insulation is covered with aluminum foil to enhance the thermal insulation properties.

Photo: mineral wool with aluminum foil

Important! During installation, the foil should be located on the side of the room. Inner warmth the room will bounce off the foil surface back into the living space.

The thickness of the mineral wool layer determines the quality of insulation and varies in size from 20 to 200 mm.

Mineral wool installation technology

Any kind of mineral wool is mounted under the frame, located between outside wall(ceiling, roof) and frame supports. As supports, you can use wooden sticks or metal profiles, depending on what kind of cladding will be used in the future.

Lathing made of metal profiles

When using lining for finishing wall cladding, the lathing frame is constructed of wood. Wooden sticks are set cross section 150 - 250 cm 2, while you can save a little the inner space of the balcony by installing sticks of rectangular rather than square section (30 × 50 cm 2, 30 × 70 cm 2).

Wooden lathing

All racks and horizontal battens are installed under the level. Fastening vertical posts To concrete surface ceiling and floor is carried out anchor bolts... Horizontal supports are attached to vertical supports. If the future cladding is made of plastic lining, the horizontal slats are attached at three levels: knee, hip, shoulder.

Insulation laying

Note: before installing the insulation, the walls are treated with an antifungal primer.

For internal insulation with mineral wool, it is mandatory to install a vapor barrier. The cotton material itself is breathable, it easily permeates gaseous substances (air, steam).

The insulation must be protected from getting wet

Considering that with internal insulation, the point of condensation formation shifts into the insulation, it is necessary to limit the ingress of steam or air from their living quarters into the construction wool. For this purpose, a vapor barrier film is inserted between the mineral wool and the finish.

Interior decoration

The purpose interior decoration:

Close the heat insulator material from the living space.
Create aesthetic inner cover walls of a room or insulated loggia.

Exists various materials for interior decoration of balconies (drywall, wood, plastic, plaster). With a previously erected lathing frame, the decoration is carried out by hanging different types panels: plywood, MDF, lining made of wood or plastic.

Lining made of plastic wood

Finishing with clapboard is performed by cladding the walls with wooden (or plastic) carriage panels that have special grooves around the perimeter for ease of installation and tightness of fastening. At the same time, plastic lining is often a cheaper imitation wood covering, laid on the inner walls of the balcony (or loggia). It is characterized by less strength and stiffness.

Plastic panels are easy to assemble

Wooden carriage panels are reliable, environmentally friendly, have sufficient flooring rigidity. Plastic clapboard you can sheathe the ceiling of the loggia, the floor is covered with wood, as for the walls - both types of carriage coatings (plastic and wood) can be used here.

Wooden clapboard decoration

After finishing the finish, the inner surface is treated with a composition that protects the wood from moisture and from destruction.
