What kind of insulation is suitable for a balcony foam or mineral wool? Do-it-yourself warming of the loggia and balcony Do-it-yourself warming of the balcony with stone wool.

Square meters of living space cost a lot of money. But in many apartments, the balcony space is used as a warehouse for storing little necessary things. In order to give these meters a second life, you can insulate the balcony with mineral wool with your own hands.

This work will require certain knowledge related to the production of preparatory work, the selection of mineral wool and the device for insulating the balcony.

Preparatory work

To preparatory work includes not only the process of preparing the surface for the installation of mineral wool boards, but also a large set of activities preceding this work.

First, the balcony is completely freed from all things. Then the roof, window units, parapet and floors are inspected for the need for repair, replacement or installation. Without high-quality performance of these works, thermal insulation will not be done properly. Only after the absolute reliability and tightness of all elements of the balcony is ensured, you can proceed to the stage of its insulation.

Preparatory work is completed only when the interior of the balcony is completely protected from wind and rain, and its enclosing and bearing capacity not in doubt or restored.

At this point, you need to make your choice of insulation, which will be installed on the balcony to protect against the cold.

The choice of mineral wool insulation

When working with glass wool, it is necessary to protect the skin and Airways

Minvata is presented in three main types:

1. Glass wool is one of the most good options in terms of price and quality ratio. It has low thermal conductivity and good sound insulation. But there is also negative side. It is necessary to work with it in a respirator, glasses and rubberized gloves.
2. Slag wool has found its application in industry. This is the cheapest type of mineral wool. Only the highest quality products can meet environmental standards. It is not recommended to use this type of mineral wool to insulate a balcony.
3. Stone, it is also basalt wool, repels water well. This indicator of stone wool is the best among other types, which means that this material will absorb moisture and collapse to a lesser extent. Produced ecologically pure species for interior finishing work.

The choice of mineral wool is impossible without understanding the required thickness and density of the material. The thickness varies depending on the climatic zone in which the work is carried out, and can range from 50 to 150 mm.

Mineral wool with a low density is suitable for walls and ceilings, and when choosing mineral wool for a floor screed device, the most rigid one is needed. So its density can be in the range from 30 to 220 kg / m 3.

Balcony floor insulation

Mineral wool can be laid in 2 layers to break the cold bridge

Balcony insulation is better to start from the floor. It can be insulated by making a screed or by assembling wooden floors with insulation.

In order to properly make an insulated screed, it is necessary to lay a rigid mineral wool on a flat, waterproofed subfloor. A thin layer of mineral wool is laid on the subfloor along the perimeter of the parapet. This belt is made higher than the main one to the level with the future flooring.

The belt is necessary to prevent the creation of cold bridges. Next, a waterproofing mixture is applied to the main insulation. After it dries, a reinforcing frame is made on the floor, which is poured with a finishing screed. Flooring can be laid on this screed.

Wooden floors are also assembled on a prepared insulated base. First, wooden logs are installed, which are pre-coated with an anti-rotting compound. To ensure an air gap, the logs must be 50 mm higher than the thickness of the mineral wool insulation.

The distance between the lags should be slightly less than the width of the insulation so that it can be tightly laid between wooden planks. Next, roll waterproofing is laid. Boards of a rough wooden floor are installed on top, on which the floor covering can be laid.

Ceiling and wall insulation

When laying mineral wool on plaster, choose a hard insulation

There are two job options. Insulation of the balcony with mineral wool for plastering and cladding.

When choosing a finish for plaster, a rigid insulation with a high density is used. It is installed on the walls and ceiling with an adhesive base. Then the insulation is additionally fastened with dowels with a wide cap, the so-called fungi.

If it is not possible to firmly fix the mineral wool or the type of finish for sheathing is chosen, then you can use a soft insulation with a low density. To install it, you will need to create a crate. It is a frame made of wooden beams or a profile mounted on suspensions. The crate is made in such a way that it is convenient to lay mineral wool in it without additional mechanical fasteners. For more information about the insulation of walls and floors with mineral wool, see this video:

Mineral wool in the ceiling crate must be installed on an adhesive basis carefully so as not to strongly compress the soft material. On top of the crate with tightly installed mineral wool over the entire area, it is necessary to fix the vapor barrier.

On this surface, you can install gypsum boards, or PVC or MDF panels.

It is more expedient to start warming the balcony at this stage from the ceiling, gradually moving to the walls.

Completion of work on the insulation of the balcony

Before proceeding to the final stage of finishing, it is necessary to decide on the power supply of the room. If lighting or installation of sockets is provided, then electrical work must be completed before finishing work. In such contractions, it is recommended to install external switches and sockets.

Since mineral wool is a universal material, there are a lot of finishing options. You can use colored plaster mixtures, perform regular painting and even paste wallpaper on an insulated balcony. There are also options for finishing with various panels and natural wood moldings, such as floor boards or decorative lining.

Having finished with the implementation of the question of how to insulate the balcony, its decoration will not take much time, and the provided power supply will turn it into a full-fledged room.

Warming the loggia with mineral wool is no different from working on the balcony. Due to the monolithic design, it is easier to keep warm in it, while you can use various options for attaching mineral wool.

A balcony or a loggia can be used as a workshop, a playroom for children, an office, a sports room and even a bedroom. To do this, you need to insulate the room. You can do it yourself without help construction organizations. First, an idea is born, then it is brought to life. So the old closet can turn into a truly useful space.

Arrangement of a balcony and a loggia can significantly increase the usable area of ​​a city apartment. Insulation will reduce heat loss, and homeowners will be able to use additional space all year round. One of the most popular materials for thermal insulation is mineral wool, which has its own characteristics.

Mineral wool is a reliable insulation and an effective sound and heat insulator.

Work procedure

To insulate the balcony and loggia from the inside, you will need to prepare fasteners in advance.

The best choice would be anchor bolts or dowel nails. Fasteners are passed through mineral wool.

The stages of warming are performed in the following sequence:

1. You need to find all the gaps and eliminate them. To do this qualitatively, it is necessary to use mounting foam, the excess of which, after drying, is cut off with a clerical knife. good choice is "Moment Montage" or "Macroflex".
2. We warm the floor. Quick installation does not provide sufficient thermal insulation. A crate is installed in which insulation is laid, a load-bearing flooring is sewn from boards, chipboard or plywood, a floor covering from, or parquet is laid on top.
3. We perform wall insulation. In this case, you will need to take several steps - installing the crate, filling it with mineral wool with laying a film for hydro and vapor barrier, cladding and finishing.
4. We insulate the ceiling. The steps of the previous step are repeated.

Common mistakes when insulating a balcony and a loggia with mineral wool

Do-it-yourself construction can lead to unexpected results. The following are the most common mistakes:

1. Using mineral wool without vapor barrier will ruin the floor and wall coverings. The material will quickly dampen, and the neighbors will find loggias on their ceiling. In addition to leaks, they may appear.
2. Selecting the wrong material for sealing gaps will lead to the creation of "cold bridges". Mounting foam should be used.
3. Internal insulation will not achieve the desired result if external insulation is not performed due to the lack of heat accumulation.
4. Improper installation of insulation on a loggia or balcony is an additional waste. The landlord will have to insulate the room again.

Video:

Thermal insulation technology for balconies and loggias with mineral wool

Mineral wool is mounted under the frame. The walls are pre-treated with an antifungal primer. The material is laid between the frame supports and walls, ceiling, roof. Metal profiles and wooden boards can serve as supports.

For a snug fit of the mineral wool to the structure, precise cutting of the insulation is required

Their choice is influenced by the facing materials that will be used for decorative finishes. If the homeowner prefers drywall, you will need metal carcass. It is written in more detail about plasterboard sheathing.

If so, then the crate is made of wood. In order to economize

We fix the vapor barrier film with a construction stapler.

the interior space of the room, install boards with a cross section of 150 - 250 cm2. The frame is mounted using building level. Vertical racks are attached to the ceiling and floor with anchor bolts. Horizontal ones are attached to the installed racks.

The use of mineral wool requires mandatory installation vapor barrier: breathable material allows air or steam to pass through. To prevent water from getting inside the mineral wool, a vapor barrier film is laid between the finish and the insulation.

The use of mineral wool for external insulation allows you to create an ideal warm walls for a balcony or loggia. The insulation process is similar to the thermal insulation methods that are used for indoor walls.

Advantages and disadvantages

Mineral wool is a fibrous material that is obtained from rocks or slags. This insulation has unique properties, they are its undeniable advantages:

1. Fire safety. Minwatane deforms at high temperatures.
2. Convenient use. The material in the form of plates is easy to cut with a knife, and the mats are sawn with a hacksaw.
3. Minimal thermal and natural shrinkage. Over time, no gaps are formed at the joints for the passage of cold.
4. Excellent soundproof properties. When passing through the material, the sound becomes weaker by 95%.
5. Non-hygroscopic and good vapor conductivity. The room maintains an optimal microclimate.
6. Excellent biological stability. Mice or mold will start in the mineral water.
7. Low thermal conductivity. High thermal resistance saves cash for repair work.

Disadvantages of mineral wool:

1. The material loses its thermal insulation properties when wet.
2. Precautions must be taken when installing insulation. For safety reasons, it is recommended to wear a respirator.
3. Over time, mineral wool begins to release formaldehyde. By themselves, these allocations are minimal and cannot exceed the allowable rate. However, if there are other sources of formaldehyde in the room, then this factor cannot be ignored.

It makes no sense to talk about the benefits of warming the balcony and loggia. The ability to reduce heat loss, the cost of heating the apartment and get additional space is attractive to the owners of any apartment.

The process is not particularly difficult. It is necessary to choose the time to complete the work and allocate money for the purchase of materials.

It is necessary to pay attention to the study of technology, the procedure and some features of insulation.

Benefits of mineral wool

Mineral wool is a group of thermal insulation materials made from the melt of various rocks and minerals.

• glass wool;
• slag wool;
• Basalt or stone wool.

Despite the diversity of composition, the term "mineral wool" usually means basalt or stone . For home insulation, it is the safest material. The characteristics of the heat insulator distinguish it from the list of other similar materials. Minvata has important advantages:

• High heat-saving qualities;
• Minvata is a reliable sound insulator;
• Light weight;
• Does not burn and does not support combustion;
• Does not rot, does not contribute to the formation of mold and fungus;
• Available in rolls and in slabs, this helps ease installation.
• Relatively low price.

The only drawback of the insulator is the ability to absorb moisture, losing working qualities. The problem is solved by installing a protective membrane. A suitable choice is stone wool insulation, released in slabs and mats. They are quite rigid, easier to install, do not lose their shape over time.

Preparation for work

Before work, it is necessary to free the balcony from all foreign objects, remove lamps, brackets, flower stands from the walls. Thoroughly clean surfaces from dust, residues old paint and other coatings.

The crumbling and exfoliated areas are completely removed, regardless of the depth of destruction.

Found cracks, potholes and other flaws should be puttied, and in difficult cases - plastered. After the putty dries, the walls are covered with a double layer of primer - a deep penetration primer.

Balcony vapor barrier

Warming is done from the inside, so you need to install. It cuts off the heat insulator from the material of the walls, excluding the penetration of water vapor. An ordinary polyethylene sleeve will do, but you can buy a special vapor barrier, which will come out a little more expensive.

The film is installed in horizontal rows starting from the bottom. Each subsequent row is overlapped at least 10 cm, the joint is glued with adhesive tape (adhesive tape).

The film is attached to the wall with mastic purchased at a hardware store. You should not doubt the reliability of the glue, since it is needed only for a while.

Lathing installation

It is needed to support the heat insulator and install the skin. It is a series of vertically arranged strips, the distance between which is carefully calibrated and corresponds to the width of the heat insulator.

With a width of mineral wool slabs of 60 cm, the step of the crate should be reduced by 0.5-1 cm in order to ensure the tightness of the installation.

The material is used wooden blocks or metal guides for drywall. The second option is recognized as optimal, since the guides have an ideal geometry, are not prone to rot and cracks, and do not burn. Installation is much easier, since all the necessary elements are on sale - direct suspensions, screws.

The first step is the marking of the walls and the installation of direct suspensions along the axes of future planks. The crate is built from the installation of extreme slats. They are carefully aligned vertically, the distance to the wall should be equal to or slightly more than the thickness of the mineral wool. Then, cords are stretched between the slats, which serve as guidelines for the installation of intermediate slats. This is faster than checking the position of each bar individually.

Wall and ceiling insulation

The insulation process consists in installing a heat insulator between the crate. The procedure is not complicated, but requires compliance with the tightness of the installation. It is impossible to allow the appearance of gaps, cracks and gaps between the mineral wool slabs.

To eliminate the shortcomings, it is necessary to keep a balloon of mounting foam on hand, which immediately fills all the irregularities found.

The gaps between the insulation plates form cold bridges, areas with active formation of condensate. The surface gets wet, materials and structures in contact with the cold bridge are destroyed. If they are not eliminated in time, the work will have to be redone in 2-3 seasons.

Particular attention should be paid to the insulation of slopes of window and door openings, the design of corners and junctions with glazing. In these places, cracks may appear, so it is necessary to install the insulator as carefully and tightly as possible.

Installation of mineral wool on the ceiling plate is carried out in the same way. To support the mineral wool, it is recommended to fix it with a thin wire stretched across the crate over the mineral wool.

Floor insulation

The principle differs little from the general technology, but logs are used instead of crates. A layer of waterproofing is laid in front of them with an overlap on the walls of about 20 cm. A vapor barrier is laid on it.

Then the logs are laid and fastened, with a step convenient for laying the insulation. Mineral wool is tightly and carefully inserted between the lags, another layer of vapor barrier is laid on top of it. A draft floor is laid from boards or sheet materials (chipboard, plywood, etc.). After that, you can lay the final floor covering.

Balcony decoration

Finishing work is carried out after the installation of the cladding, which is attached to the laths of the crate over the insulation.

On top of the mineral wool, it is necessary to install a vapor barrier that prevents the insulator from getting wet, which makes it lose its properties.

As a sheathing, it is easiest to use plywood, plasterboard, chipboard, MDF and other sheet Construction Materials. Joints between individual sheets and recessed screws are puttied, the sheathing surface is primed, then the finishing layer is applied - paint, wallpaper or textured plaster.

Watch the video:

Some owners prefer the installation of lining, which combines the skin and finishing and needs only a coat of varnish.

The development of the window industry has led to the emergence of profile structures of balcony frames that can effectively retain heat in the room, with a high degree of noise absorption from the street and protection from precipitation and dust.

As a result, homeowners have a great opportunity not only use the balcony room for a comfortable exit outside the apartment at any time of the year, but also use it as a residential one. Many, having insulated the balcony with mineral wool or polystyrene foam, remove the balcony door leaf, thereby increasing the amount of usable living space. The resulting space is used for their own purposes - they take out a refrigerator to the balcony or loggia, hob and lockers, make a workshop or office out of them.

To achieve the maximum effect of preserving heat in the room, along with the right choice balcony frame, it is equally important to decide how to insulate the balcony from the inside, that is, choose a heater.

In the construction industry, two types of insulating material are equally widely used - expanded polystyrene (polystyrene) and mineral wool, each has its own technological advantages and disadvantages.

Fig. 1 Do-it-yourself insulation of a balcony with mineral wool

A loggia or balcony insulated from the inside belongs to the category of residential premises, therefore, increased requirements are imposed on the insulation material. The main criteria for comparing foam and mineral wool can be the following material parameters:

Thermal conductivity

The heaters must high degree match its name. Low thermal conductivity will not only save the material, reducing the cost of its purchase, but also thermal and electrical energy for heating, for which you have to pay. Less thermally conductive material will take up less volume with the same characteristics as its counterpart - this is important when used on a small balcony.

Environmental friendliness

The main requirement for all materials used in the decoration of residential premises, because health is the most precious thing.

fire safety

For balcony heaters, it is important to be protected from matches or cigarettes falling from above, but they are unlikely to get on an unprotected surface - the insulation of loggias with mineral wool and foam after installation is subjected to surface finishing. In a fire, resistance to ignition and the absence of harmful and toxic products of release when exposed to direct fire or high temperature on the material are equally important.

Soundproof properties

The insulation mounted on the walls of a balcony or loggia affects sound absorption to a much lesser extent than balcony frame, so the parameter is not so important.

Fig 2 Basalt mineral wool

Hygroscopicity and vapor conductivity. Insulation, mounted on the concrete walls of balconies and loggias, should not absorb and accumulate moisture from the plates. Its vapor conductivity, which contributes to the ventilation of the premises, is not so important - the material is subjected to surface finishing.

Life time. The insulation should not decompose and lose its physical (shrinkage) and chemical (decomposition) properties for a long time and from the influence of climatic factors.

Ease of installation. The insulation material should be easy to process and install, it is desirable that its surface be flat and smooth to simplify further finishing.

biological stability. The material should not contribute to the formation of mold and fungus.

Price. The price of insulation for finishing a balcony is not so significant due to the low consumption of material due to small area premises.

The main parameters of mineral wool

Rice. 3 Insulation of the loggia with mineral wool in rolls

The industry produces several types of mineral wool for insulation of building facades and internal walls premises:

glass wool

Made of thin glass threads 5 - 15 microns. length 15 - 50 mm., has a thermal conductivity of 0.038-0.052 W. / m. * K., resistant to high temperatures up to 450 C, does not burn. Currently obsolete and is not used for domestic insulation due to its harmful properties– flying sharp glass (work requires a respirator and protective clothing.)

slag wool

It is obtained by processing blast-furnace slag into thin fibers 16 mm long. and 4–12 µm in diameter. The material absorbs moisture well and is caustic, non-flammable, emits harmful substances, therefore it is not used for external insulation and in residential premises. It has a thermal conductivity of 0.46 - 0.48 W. / (m. * K.) and withstands temperatures up to 250 C, forms an acid when moisture enters, corroding metal structures.

Basalt (stone) wool

Insulation made of mountain basalt made of thin BTV (thickness 5 - 15 microns.) or super-thin BSTV (thickness 1 - 3 microns.) fiber is designed for use inside residential premises (insulation of the floor, walls and ceiling), is available in the form of rolls, mats or plates.

Rice. 4 Thermal insulation of the balcony floor with stone wool in sheets

To insulate balconies, it is more practical to use 50 mm thick plates, which are easily mounted on umbrellas or glue and are easier to handle. outdoor decoration unlike roll types that require a frame to install.

Main specifications fine-fiber basalt slabs:

Thermal conductivity. The coefficient of thermal conductivity of a stone slab is 0.46 - 0.48 W. / (m. * K.).

Soundproofing. Fine fiber stone slabs have a maximum sound absorption coefficient of 0.80 - 0.95%.

Hydrophobicity. The structure of the board allows it to absorb moisture, which fills the air voids between the fibers without being absorbed into the material.

Flammability. The material is not combustible, the melting point of basalt fiber is about 1000 C.

Vapor permeability. Mineral wool from basalt passes air well.

Biological and chemical stability. The composition of basalt does not include organic matter that promotes the formation of fungus and mold. The material is not afraid of exposure to acids.

Treatment. The slabs are easily cut with a hacksaw and adhere well to the walls, their surface perfectly retains plaster solutions when the mesh is applied.

Physical characteristics. Stone wool slabs have a density of up to 400 kg/cm. cubic, thanks to which they retain their geometry and are not subject to stalling and shrinkage.

Environmental friendliness. Like all natural materials basalt is harmless to human health.

Properties of foam (expanded polystyrene)

Figure 5. Styrofoam structure

The material is pressed granules of expanded polystyrene with a diameter of 5 - 15 mm. Styrofoam for 98% consists of air enclosed in granules; pressed plates 30 or 50 mm thick are used to insulate balconies. with a density of 25 - 35 kg / m. (this parameter is indicated in the foam plastic marking - PSB 15,25,35). The most dense brand of foam plastic PSB-35 according to GOST-15588-86 has the following physical characteristics:

Thermal conductivity. In polystyrene, it is considered lower compared to mineral wool, its maximum value is 0.037 W / m * K.

Hydrophobicity. The material practically does not absorb water, water absorption is 2% of its mass.

Noise isolation. The material does not have a very high noise absorption rate, reducing its level by an average of 4 dB.

Temperature stability. Styrofoam is classified as a combustible material of class 3-4, its melting point is 270 C. It ignites at a temperature of +491 C. and does not support combustion, having a self-extinguishing time of about 4 seconds (for fire resistance, a fire retardant is added to its composition, indicated in the marking with the letter C) .

Resistant to chemicals and bacteria. The material is resistant to most household chemicals, does not support the formation of mold and colonies of microorganisms.

Environmental friendliness. According to the manufacturer, the material is inert and does not emit substances harmful to health. There is another opinion, according to which the foam releases styrene and mass harmful substances during oxidation.

Mounting. The foam is perfectly processed, its smooth and smooth surface good for applying finishing materials.

Price. Styrofoam is cheaper than mineral wool by 2 - 2.5 times.

Rice. 6 Thermal insulation of the balcony floor with foam plastic from the inside

When deciding what is better to insulate a balcony - with foam plastic or mineral wool, in the case of concrete walls, you can give preference to dense foam (PSB-35) - the material is cheaper, it can be processed and finished perfectly, and has a lower thermal conductivity. In addition, basalt wool when mounted on concrete plates without vapor barrier, it can absorb moisture from them - this significantly reduces its heat-shielding parameters.

If a balcony with a metal railing is insulated, it is preferable to use stone wool, which has high sound-absorbing properties.

The loggia has an area that winter time it is desirable to make it comfortable for living. To do this, it is necessary to make it warm. One longitudinal side of the loggia borders on your apartment, the second one goes out onto the street, the sides adjoin the walls of the neighbors. Based on this, special attention should be paid to the open side on which the windows will be located.

Glazing

Most of the heat escapes through the window space. Considering this, it is necessary to put quality windows. Best to choose plastic windows with two double glazing. They are durable, practical, have good soundproofing. Their only drawback is that they do not let air into the room, which can lead to an increase in condensate. To avoid this, it is necessary to ventilate the loggia more often.

The choice of insulation method

It is necessary to decide on the method of insulation: outside or inside. When choosing an option, you should consider where the dew point will be. The dew point is the temperature at which water vapor condenses for more than cold side. With external insulation, the wall remains warm, the living space inside the room is not lost. outdoor method much more efficient than internal. But this option is associated with technical difficulties, since it can only be performed by industrial climbers. When insulating from the inside, the thickness of the selected material should be increased, and the work itself should be done by hand.

Material selection

The choice of materials for insulation is very large. It can be various types of foam, mineral wool, polyethylene foam. The cheapest way is to insulate the loggia with mineral wool. Wool is a fibrous material obtained by melting different kind raw materials. It can be glass, volcanic rocks or slag blast furnaces. In this regard, there are several types of this insulation: glass wool, stone or basalt wool and slag. These materials are good insulators, have good sound absorption, are light and easy to install, but are susceptible to moisture.

glass wool

Glass wool has a high wrinkle in the wet state, increased fiber fragility. The smallest fragments of glass wool can penetrate the lungs, eyes, get on the skin, so this material must be tightly packed in plastic bags. When working with it, for safety reasons, it is necessary to use gloves, goggles, a respirator, overalls. Cotton wool can be produced in rolls, mats and plates.

stone wool

Stone or basalt wool is the highest quality. It is non-flammable, durable, resistant to deformation, easy to install, more dense. Its shrinkage is no more than 5%. Mostly produced in slabs. It is desirable to stop your choice on it. Use plates with a thickness of 50-100 mm.

slag wool

Slag wool is good for insulation, but it is very hygroscopic and has low vibration resistance, which is why its durability is low. Therefore, it is less in demand.

Floor insulation

The floor plate, first of all, is cleared of debris. Waterproofing is placed on the cleaned floor. It can be thick polyethylene or roofing material. On top of the waterproofing layer, a crate of wooden beam having the same thickness as the material. It needs to be processed
antiseptic. The crate is attached to the floor plate with dowels. Then, a heater is placed in it, between the bars. It should be borne in mind that mineral wool with a low density will shrink. Therefore, the dimensions of its sheets should be larger in area of ​​the space where it is inserted. The inserted insulation is covered with polyethylene, which is fastened to the bars with a stapler.
The flooring can be done: - with a floorboard, having processed it with foam, which will save its characteristics. It is advisable to use a grooved board with grooves and protrusions; - OSB board. We nail the plate or attach it with screws to the crate. We put laminate on it. It can be covered with linoleum or carpet after the walls and ceiling are insulated.

Insulation of the ceiling and walls

If the floor of your neighbor on top of the loggia is insulated, then the insulation of the ceiling of your loggia disappears, but it is better to make its sheathing. The wall adjacent to the living room can not be insulated, as it is warm. It is better to perform electrical wiring on it for installing sockets and a switch.
To insulate the ceiling and walls, it is necessary to make a crate from a bar with a section of 50x40 mm in increments of approximately 500 mm. The installation of the bars must begin from the corners of the loggia. Attach the bars to the ceiling and walls with self-tapping screws and treat with an antiseptic. Then start the warming itself. The cut sheets of mineral wool are glued with special glue to the wall and ceiling of the loggia. The glue should have the consistency of sour cream. They need to generously lubricate the bonding surface. Additionally, sheets of insulation can be attached with dowels "fungi".
The next stage of insulation is vapor barrier. It can be done with dense polyethylene, but it is better with foil-foamed polyethylene. The foil should be facing the inside of the loggia in order to retain heat in it. After insulation, we carry out final work. We nail the finishing coating to the bars of the ceiling and walls. It can be PVC lining, wooden lining or other materials. We fix skirting boards on the floor, and install special corners to the corners of the walls and between the walls and the ceiling.
The insulation of the loggia with mineral wool has been successfully completed and your loggia is ready for living in the cold season.
