Fire-resistant drywall: fire-resistant and heat-resistant, whether plasterboard burns, fire-resistant characteristics and limit

It is possible, but not always. Much depends on whether the plasterboard layer is decorative or working, and what is the distance from the stove well to the plasterboard layer. Please note that it is impossible to decorate a fireclay brick or iron stove without a special cushioning layer. If you simply lean a sheet of drywall against the wall of the stove, it will deteriorate after a while. And this is at best, and at worst it will catch fire or decay. The fact is that drywall consists of a layer of gypsum and two layers of cardboard, between which there is a layer of gypsum. Cardboard is a flammable material that spontaneously ignites at high temperatures. The intensity of drywall combustion depends on how hot the oven is. This is why it is so important that there is sufficient distance between the furnace well and the layer of drywall. If the cardboard around the plaster burns, it's not so bad. Then the evaporation of water from the gypsum will begin. Cracks will appear on it and the plaster sheet will collapse. The casing will crumble. If the stove is heated regularly, without special measures the layer of drywall will completely collapse in 5-30 days (depending on how often you heat it).

SNiP standards for the location of the furnace from the walls

The standards for these requirements are specified in 2 main documents:

SNiP III-G.11-62;
SNiP 2.04.05-91.

Based on these regulatory documents, each owner of a solid fuel stove is required to maintain minimum clearances from the wall and ceiling, taking into account the surface material:

Parameter	Requirement
Installing the stove on a floor made of flammable materials.	The distance to the bottom of the stove must be at least 140 mm.
Foundation size.	When installing a steel stove on a wooden floor, the size of the foundation should be 1000 mm larger than the dimensions of the stove.
The ceiling is protected by asbestos slabs, plaster and sheet metal up to 1 cm thick.	In this case, the brick-lined stove is made in height so that the gap to the ceiling is at least 250 mm.
When installing a steel stove with a protective layer of thermal insulation.	The minimum distance to the floor slab is 700 mm.
Installation of a steel stove without a protection layer.	This size increases to 1000 mm.
Minimum dimensions for walls according to SNIP from 1962
Distance from stove to wood stove with unprotected surface.	From 1000 mm.
The walls are lined with brick and plastered with lime mortar with a layer of 25 mm. Or an asbestos heat insulator 4 cm thick is fixed.	130 mm
The wooden walls are lined with brick, 120 mm thick and plastered with lime and asbestos. When installing protection on the walls in the form of a 40 mm asbestos-vermuculite slab.	300 mm

By maintaining the minimum dimensions, or better yet, making gaps with a small margin, every owner of a wooden house can be sure that its walls and ceiling are protected from high temperatures.

One of the main methods of protection is the manufacture of devices installed to protect the front and side surfaces near the stove itself.

Topic: What material to choose for finishing the wall next to the stove?

In a country house, the brick stove (Economka) is located very close to one side of the wall (log house). The distance at the nearest point is about 12 cm. Currently I am decorating the walls from the inside of the room with a blockhouse. So the question arose. If you drive the space behind the stove with a blockhouse, it will lie almost flush, which is not good. What material can be used (asbestos is not desirable, since the room is a living room, children, etc.) to cover this particular section of the wall. Size 135x140 or larger. I wanted minerite, but couldn’t find any larger sizes.

Flama

I made insulation, a galvanized sheet, and on top, porcelain tiles in the color of granite facade 600x600 on clamps for the ventilated facade - these materials were simply available. It turned out beautiful. If the pipe is not insulated, the wall will have to be closed not only behind the stove, but also along the pipe. I have a corner fireplace stove, it’s also 10-12 cm from the wall, the pipe under the ceiling goes into a brick chimney - first I finished the wall just behind the stove, the lining on the wall opposite the pipe got very hot, darkened, tar started flowing, I had to raise the wall finishing before the pipe enters the brick chimney - it’s easier to install an insulated pipe.

There was no flama in our village. Apart from mineralite, there is nothing and that is not available today, only to order (1 month wait), and stainless steel with basalt cardboard as an option. But after a detailed examination, it turned out that the wall of the furnace, which is adjacent to the wall of 2 bricks and does not heat up particularly strongly during the fire. So the question is removed. I will trim it with clapboard directly onto the frame (so as not to steal the distance), pre-treated with several layers of fire protection. Even if it gets dark - well, to hell with it - you still can’t see it behind the stove.

At least just attach a screen to the bushings, just in case there’s a fireman!

Protective screens near or around the oven

Such a system will need to be implemented when installing a potbelly stove in the corner of the room. You can mount or lay out several screens from brick, installed at a short distance from each other. In this case:

The first screen protects a person from touching the iron stove and getting burned. It is usually made of refractory or fireclay bricks;
To protect walls made of flammable material, a second layer of protection is provided. It can be made of brick or covered with a barrier made of sheet steel with a mirror-like front surface. In this case, heat waves will be reflected from the mirror and spread faster throughout the room;
if the foundation is insufficient in size or it is impossible to manufacture it, it will be necessary to lay a protective screen made of durable fire-resistant material on the wooden floor. This can be a sheet of steel or a decorative layer of heat-resistant clinker tiles or porcelain stoneware. The surface will first have to be covered with a layer of thermal insulation.

Installation of metal screens

This is the easiest way to make surface protection. It is better to use sheets with a polished front surface. Before fastening, the wall surface at the required level along the height of the screen is covered with a layer of thermal insulation. In this way, we protect the surface of the walls from the effects of heat.

You can lay a layer of thermal insulation or fasten the metal with self-tapping screws with inserted ceramic spacers. But it is better to attach the screen to strips or a metal profile treated with a layer of protection. In this option, the air gap will not allow heat to pass freely to the walls, and reliable insulation of the stove from the wooden wall is ensured.

A special gap is made at the bottom of the wall for the passage of cold air, ventilation of the wall and screen. When arranging a wall with a layer of thermal insulation, a number of longitudinal guides are installed on the surface. The space between them is filled with a layer of mineral wool or other material. Then sheets of metal are installed and screwed to the sheathing with self-tapping screws.

In this design, there is no need to leave a gap at the bottom. The air will not be able to pass through calmly, but the wall will be reliably protected from high temperatures. To protect the floor of the house, a slab made of non-flammable durable material can be used.

Brick screens

This protection option is usually installed near the stove. Thus, you can protect not only the wall, but also the person from burns. By installing a brick wall, you can reduce the distance from the stove to the wall. For laying, it is better to use ceramic or fire-resistant bricks.

The work is carried out in several stages:

you will need to make a small foundation or remove boards from the floor along the marking lines for laying the screen and, by drilling holes in the concrete of the base of the building, insert metal rods to fasten the bottom of the wall and the foundation;
Having leveled the floor surface, lay out a layer of mortar and lay the first row of bricks; you need to place the bricks in the same plane without distortions. This determines how level your entire wall will be. Do not forget to make small grooves for ventilation; for this you can move several bricks of the bottom row.
checking the level and pulling the twine for laying each subsequent row, all bricks are laid on a mortar of clay and sand. Having raised the wall to the required height, the top is sealed with a layer of mortar or covered with a board. This way you can make a shelf for decorative ornaments and all sorts of little things.

Finishing the walls around the stove

1. Non-flammable needle-punched thermal insulating glass sheet is ideally suited for a stainless steel screen. Its advantages:

absence of resin that releases toxic gases when heated;
ease of installation. 2. The heat-resistant Rockwool FireBatts mat, supplied from Denmark, is also good. This product of the ROCKWOOL Group of Companies:

made of basalt wool, Rockwoo - hygroscopic and heat-resistant;
withstands temperatures up to 750 degrees C.

If your bathhouse is a wooden frame, then:

when finishing the walls around the stove with mineralite, it is advisable to leave a 3 cm air gap, using the same ceramic bushings. Air will circulate between the wall and the mineralite sheet, preventing them from heating to extreme temperatures. Heat-resistant tiles on top of mineralite sheets will decorate the walls and provide additional security;
The walls in the bathhouse adjacent to the metal stove are also protected using red solid brick. We spread it to the height of the stove, but, if desired, it can go up to the ceiling.

Separately, I would like to dwell on heat-resistant tiles.

A good option is heat-resistant Miami tiles with imitation weathered sandstone, produced by the Russian company. A little more about her:

The main thing is that this tile is environmentally friendly. The basis is kaolin clay of various rare varieties. No dyes or chemical additives are used;
This material is universal: it is used both for internal and external cladding;
the color scheme is very expressive and does not change due to exposure to high temperature;
it is strong and durable;
has good air and vapor permeability;
the maximum temperature that this fireproof tile can withstand is 1100 degrees C;
fix the tiles using heat-resistant “Terracotta” glue. The company also produces grout for joints.

The company produces tiles and other textures, each of them has its own unique charm. This:

fireclay;
flagstone;
old lock;
wood chip;
old brick;
papyrus;
torn stone and others.

Remember: before gluing heat-resistant tiles, apply heat-resistant mastic to the mineralite slab.

Protective screens are insulation panels that cover the side surfaces of the furnace and reduce the intensity of thermal radiation. Screens can be metal or brick. As a rule, they are used for metal furnaces.

The most common protective screens are factory-made steel or cast iron sheets. They are installed around the stove, at a distance of 1-5 cm from the walls of the firebox. Depending on the need to insulate one side or another of the furnace, you can purchase side or front (front) screens. Many metal furnaces are initially manufactured with protective screens in the form of a protective casing.

Protective screens make it possible to reduce the temperature of external metal surfaces to 80-100°C and, accordingly, reduce the fireproof distance to 50 cm. The total distance from the firebox to the wall (including a gap of 1-5 cm) will be 51-55 cm.

Installing protective screens is not difficult. Thanks to the presence of legs, metal panels are easily bolted to the floor.

A brick screen can cover all the side surfaces of a metal furnace, representing its outer cladding. Then the stove will be in a casing made of brickwork. In another case, a brick screen is a wall separating the stove and the flammable surface.

Types of materials

Refractory materials can be roughly divided according to the method of heat transfer:

Heat reflective – aimed at reflecting infrared radiation into the room;
Preventing loss due to its physical and chemical properties.

On video of fireproof materials for walls around furnaces:

But all of them can also differ in the type of raw materials from which they are produced:

With organic components , for example, polystyrene foam materials, although their fire resistance is very low, they are best suited for walls near stoves with low heat;
Inorganic is a broad class of non-combustible materials for insulating walls of a wide variety of fire resistance, including very flammable ones, such as wooden floors. These include stone and basalt wool, pressed into large slabs, fiberglass wool, lightweight cellular concrete slabs with fire retardant impregnations, honeycomb plastics, foamed perlite or vermiculite, and polypropylene. However, such a beautiful decorative thing as Leroy Merlin sheet plastic is definitely not suitable.
Mixed type - these include asbestos-cement refractories, asbestos-lime or silica, foamed from a variety of inorganic substances.

Basic requirements for refractory materials

Many country buildings are built from wood, be it a cylindrical or frame house; without a stove or fireplace it is difficult to survive a frosty winter, so their arrangement is approached very carefully, and the materials placed around the stoves are chosen so that they are:

Effectively and reliably prevented any attempted fires;
Environmentally friendly, so that when heated they do not release harmful substances into the home air.

Information from this article will help you understand what composition of mortar for plastering a stove exists and is most often used.

But what are the dimensions of a standard oven brick can be seen here.

For walls around stoves

A long time ago, people used asbestos sheets to line the walls around stoves, but it turned out to be very harmful to health and the environment - its microparticles can enter the lungs or be deposited on things, which leads to serious illnesses, and with strong heating they also release carcinogenic substances. substances. Therefore, the best materials can be considered:

Fire-resistant plasterboards. can act as the basis for covering walls around hot stoves, and for decoration, porcelain tiles of the most unusual colors can be used.

The sheets have the following characteristics:

Fire resistance – up to 30 minutes of fire resistance;
Does not ignite for up to 1 hour even after a fire has formed;
Slab parameters – 120 x 250 x 1.25;
On the front and back sides there is cardboard treated with gypsum, inside there are fiberglass threads that will resist fire;
The ends of the sheets are covered with cardboard material, and there is a joining chamfer along them;
Fastening can be done either using adhesives or self-tapping screws.

Fireproof minirite slabs. The material has excellent heat-resistant properties and is produced exclusively from environmentally friendly substances, including:

Compositions of white or gray cement make up up to 90% of the total material;
Included are mineral fibrous materials;
For strength and durability, fiber reinforcing boards are used.

Asbestos fiber is completely excluded from the composition, which improves the quality of the material for a home stove. It is easy to fix it to the wall with screws close to the wall itself; for reliability, you can mount 2 sheets of minirite. Note! When installing, it is necessary to leave a small distance, since the material may increase in size when heated. For other walls, you can choose a similar decorative brick finish.

Protective stainless steel sheets are a slightly expensive but reliable fireproof material that can be used to protect not only the walls of the house, but also the basement when installing a heating boiler.
But in order to provide the greatest protection, special fiberglass with thermal protective properties should be placed under the stainless steel - the structure will reliably protect the house from any attempts to start a fire. Choose the substrate carefully so that it does not contain harmful phenolic resins; when heated strongly, they release substances that are too hazardous to health.

Manufacturers and prices

Basalt fiber panels cost 1 sq. meter - from 390 to 690 rubles, depending on the decor of the front side, produced by ESCAPLAT;

Rolled fire-resistant non-woven material - cost of 1 linear meter from 112 rubles, produced by OgneuporEnergoHolding, LLC, Moscow;

Non-flammable composition for plastering walls with a volume of 20 liters at a price of 410 rubles per bucket, produced by a company from Perm.

Wooden baths require especially careful compliance with fire safety rules when arranging them. The source of the fire can be anything, an unextinguished cigarette, coals falling from the furnace of the firebox, an uncleaned chimney, but the main source of threat remains the stove itself.

The surface of the stove heats up to 300° - 400°, the heat falls on the wooden walls, which leads to their excessive heating and charring. It is extremely difficult to stop the process of ignition of wooden surfaces; the best way to avoid a fire is to prevent it. There are two truly effective ways to insulate the surface of wooden walls from the heat of sauna stoves - protective equipment in the form of a screen or the construction of special cladding from non-combustible materials.

The best ways to protect walls from a stove in your home

Protecting the walls in the house from the stove is one of the main works that you should pay attention to when finishing the room.
Therefore, it is important to familiarize yourself with the requirements of building regulations to ensure the necessary clearances from the stove in the building and responsibly comply with them. Wooden baths require especially careful compliance with fire safety rules when arranging them. The source of the fire can be anything, an unextinguished cigarette, coals falling from the furnace of the firebox, an uncleaned chimney, but the main source of threat remains the stove itself.

Table of contents

Installing a stove is a complex process and requires a lot of attention to each stage, from preparing the installation site to the nuances of removing the chimney pipe from the roof. In this article we will talk about how to properly insulate a wooden wall from a steel or cast iron stove. Any wood has a predisposition to ignition, so a constantly hot stove design can easily cause a fire.

Any builder understands that insulating the wooden wall behind the stove is a mandatory process. Let's look at an example of installing a Bavaria stove-fireplace on a wooden floor next to a wooden wall. The furnace does not have a separate foundation, so a light base for a metal structure is required. The base for the stove will be laid out with bricks in one layer.

In this case, wall insulation can be done in two versions: asbestos cement sheets or flame sheets (non-hot composition). There are several opinions about asbestos - sometimes they say that they emit toxic fumes. But flamm has its drawbacks: they have standard sheet sizes of 600x1200 mm, which can be inconvenient when working, and also in terms of price they do not beat asbestos cement at all.

get rid of the existing partition, replace it with a fireproof one and cover it with tiles or stone. You can also place a screen and use a circular saw to remove the wood on the partition completely. Next, finish with tiles, plaster or paint. There is no doubt that the tree needs to be removed. After all, if you cover it with non-flammable materials on top, there is still a chance that the wooden surface will ignite.

In this case, it is better not to take risks and remove the partition from wood. Thermal radiation from the oven will not only be from the back wall. Lateral radiation will also emit radiation onto the wall at a distance of 0.8-1 meter. You should carefully read the installation instructions - the manufacturer describes everything very clearly there, including what concerns safety. For example, when a stove with a glass door is on and there is a chair next to it, it is better to move it further away (more than 1 meter).

Initially, the base for the stove was supposed to be one brick thick, but such a thickness for a wooden floor is not very good. Regarding the non-combustible partition, you should also note the importance of the situation - where the chimney will go, at what distance from the beams, walls and rafters. In the area of this Bavaria stove, it is best to use a concrete slab as a base - lay it along the beams, flush with the floors or a little more - it will turn out like a podium, reliable and ensuring safety.

However, the bottom of this stove practically does not warm up; there is an additional part for firewood, which takes on the heat. Therefore, you can make it simpler - lay mineralite or CSP on the floor, then tiles or porcelain tiles on mastic or hot melt adhesive. In places where the chimney pipe is laid, you can use basalt, non-flammable or kaolin wool.

Cotton wool plays the role of additional insulation and is placed in the ceiling section. In this case, you should make an opening in the ceiling - in accordance with safety standards - from the contour of the two-layer pipe - sandwich, 250 mm in different directions. The furnace cutting should be made of non-combustible materials - superisol, mineralite, calcium silicate, vermiculite. When passing through a chimney pipe, the groove should be filled with cotton wool.

It is, of course, very difficult to get rid of a beautiful partition, because it was built for aesthetics, a lot of time was spent on it, but if it was decided to install a metal stove against this wall, then you should get rid of the additional threat of fire of wooden parts.

Facing materials are often made from cement, the complete hardening of which can take several years. As a result, even after the work has been completed, changes in size, bends and deflections may be observed. Some manufacturing companies (for example,), use an effective and efficient method of keeping facing materials in an autoclave in a high-temperature, high-pressure oven. And it turns out that shrinkage due to drying and expansion by exposure to heat can be avoided, and reliable strength is also ensured.

Those same Nitikha panels are made from fiber cement, a universal material that consists of 90% cement and 10% cellulose fibers and various mineral fillers. In this case, technology without the use of asbestos is used by pressing the ingredients.

Panels of this type are environmentally friendly; their production does not use formaldehyde resins, chlorine compounds or asbestos. Fiber cement has excellent fire-resistant properties; it fully fits into the category of non-combustible materials. Fiber cement siding has many advantages, including the fact that it can easily be used to select various design variations, and it is also easy to install. Instead of mineralite, you can also use glass magnetic sheets - this is a more budget option.

Here's another example of making a fire-resistant wall located behind the fireplace:

treating the wall with fire protection (about 5 layers);
fireproof mats are attached with a stapler;
The slabs are attached through ceramic bushings - there are gaps at the bottom and top.

The decorative panels available are slightly flammable according to the fire classification. It turns out that only a 5 mm layer of basalt cardboard really protects the wall from fire. However, the oven is convection in nature and its outer surface does not heat up much. If you follow the manufacturer's instructions, it will not heat up more than 60 degrees.

You can pay attention to the color of the first mono-pipe; the most furnace heat emanates from it. From the floor to the sandwich pipe, the wall should be reliably covered with super-insulation, especially since the stove is installed close to the wooden partition. In this case, when thermally insulating the partition, you should also pay attention to the cutting.

You also need to be careful about fiber cement boards; they come in two types: moisture-resistant for the facade and for landscaping fire-resistant partitions (the second option is gray in color, there is no paint or pattern).

Minerite panels, painted with acrylic (sometimes even in several layers, 5-6), belong to the category of low flammability and low combustion support. Because of the acrylic, the entire slab cannot be classified as “non-flammable”, and this is very bad; such panels, supposedly resistant to fire, are often used just when it is necessary to insulate wooden walls behind the stove - mineralite panels coated with acrylic look It’s beautiful, but, unfortunately, it won’t reliably save you from a fire.

We invite you to familiarize yourself with the steam room, washroom and relaxation room

If it suddenly turns out that you bought mineralite coated with acrylic, then you need to get rid of such “protection” of the wall. You should dismantle the panels - this is not difficult, in their place you glue gray classic mineralite onto a galvanized profile, and then terracotta tiles are glued onto it using heat-resistant tile adhesive. With such reliable thermal insulation you can sleep peacefully.

It also happens that gypsum board is used as protection. If the gypsum board is not protected by anything, then it will not play the role of high-quality thermal insulation. If the gypsum board is fixed to a tree with a metal profile, and tiles are attached on top of the gypsum board, then such protection is possible. Bare gypsum board should not be used for such purposes; its flammability class is G1, not NG (non-flammable). When installing, it is necessary to take into account the distance from the stove to the wall.

If the oven is operating normally, nothing should happen in any way. But the fire safety measures specified in the stove manufacturer’s passport must be observed. The distances to fireproof and combustible structures are clearly stated there. Gypsum is a good heat insulator, but its features should be taken into account.

If the wall is wooden and gypsum board is attached close to it, therefore, when it is heated, dampness will form behind it, since the wall is cold. The wall itself also shakes - the tree always lives its own life at different humidity levels and temperature fluctuations in the environment. The profile is necessary not only to create an air ventilation channel behind it, but also for the durability of the entire structure. The tile adhesive needed here is one that is suitable for heated floors.

It is imperative to take into account fire safety standards when installing important distances. If you calculate the distance from the metal firebox to the wall, then it is more logical to add another 65 mm to such offsets - this is the thickness of the brick, which any metal stove does not have.

It turns out that the open setback to the unprotected wooden part is 320 mm (65 mm), resulting in 385 mm - this is the minimum value.

To the protected wooden part 260 mm (65 mm), and a minimum of 325 mm is obtained.

When is this required?

There are times when there is no need to protect walls. If the stove is located at a safe distance from the wall from a fire safety point of view, the installation of protective screens and other measures can be neglected. The distance from the walls that is required to reduce the heat from the source varies:

A stove laid in a quarter of a brick should be located no closer than 35-40 cm from the wall;

A metal stove without lining should be placed a meter away and no closer;

A metal one with a lined furnace can be installed 70-75cm from the wall.

However, not every steam room has the opportunity to fulfill these requirements, due to the small area. The layout of steam rooms with an area of 6-8 m² can hardly accommodate the necessary set of items for the steaming procedure. Therefore, the need to insulate walls with special sheathing is relevant.

The wall next to the stove - country forum

Quote (lenapetrusha @ 11.2.2013, 14:38) I ask for advice.
We have built an aerated concrete house, there are stoves on the ground floor - one in the room, the second against the same wall - in the kitchen. Now the kitchen is being finished: tiles have been laid on the floor, the walls have been covered with clapboard, and only the wall with the stove has been left. How to properly and beautifully (if possible) finish it? The wall is aerated concrete, there is a distance of about 15-20 cm between the wall and the stove. Maybe with tiles, what kind, and is it necessary to plaster the wall under it? Teach me, please. Forgive me generously, but... somehow your message makes me feel uncomfortable. In my understanding (not necessarily correct), aerated concrete must be protected from the high temperature that the stoves will “give out”, and only then think about how to decorate the wall... 15-20 cm is very little. Very close.

My house is made of gas silicate. The wall where the fireplace and chimney are is made (entirely) of red brick, precisely for the reasons stated above (this despite the fact that the chimney is a sandwich). As well as the part of the wall through which the pipe (ceramics) from the gas boiler is laid.

“Like a moth to a garment and a worm to a tree, so sorrow harms a man’s heart” (Proverbs 25:20).

Application of protective screens

Screens are shields made of brick or metal that protect walls from intense thermal radiation. Similar protection is used when installing metal stoves.

Metal screens are made from steel or cast iron sheets, these

casings surround the heat source with a distance of 3-5cm.

Advice! When purchasing a metal sauna stove, you should give preference to a model equipped with a metal casing. Its cost is not much higher, but the issues of wall insulation are eliminated.

Additional frontal or front shielding, which is located on the walls depending on the location of the stove, will not hurt. The protection guarantees the wood from overheating, reducing the temperature by 100 degrees or more, and provides the opportunity to save space in the steam room. A stove protected by a casing can be installed at a distance of 50-55cm from the wall.

Covering bathhouse walls with non-combustible insulating materials

To prevent the walls from overheating, you can use materials with increased thermal insulation properties and inertness to high temperatures. Two types of materials are used:

reflective;
fireproof with lining.

The first type includes materials for wall cladding, consisting of thermal insulation with fire-resistant properties and a metal covering in the form of a sheet.

Insulating walls with reflective sheathing

A protective cake with reflective materials is done this way. First, the thermal insulation is attached using ceramic bushings directly to the wooden walls, then it is sewn up with a stainless steel sheet.

Advice! It is better not to use galvanized metal, since heating may release heavy metals harmful to the human body.

Stainless steel with a polished surface reflects the heat flow inside the steam room, reducing heat loss. In this case, reflected heat is more useful than direct heat. For thermal insulation use:

basalt cardboard or cotton wool, the only material with increased hygroscopicity, non-flammable, environmentally friendly;
asbestos cardboard, which reliably protects against flames and has a long service life;
mineralite, an artificial material made specifically for these purposes.

Protective sheathing requires ventilation gaps of 2 cm from the wall to the insulation, 2 cm from the insulation to the steel sheet. If it is necessary to install the stove as close to the wall as possible, make a double skin of non-combustible insulation, use ceramic bushings to maintain gaps of 2-3 cm and sew them up with a steel sheet.

Insulation with cladding

Measures to protect walls with cladding are necessary in order to preserve the interior decoration of the room. They are more expensive, but no one has canceled the aesthetic advantages of the bathhouse. It is based on tile cladding, which is laid on fire-resistant cladding made of gypsum plasterboard, non-deformable gypsum-based cardboard with fiberglass, mineralite, non-flammable cement-fiber material, moisture-resistant and resistant to biochemical influences, LSU, fiberglass material bound with magnesium additives, resistant to high temperatures, high humidity. Heat-resistant glue is used for installation.

Advice! Use heat-resistant reinforced Terracotta glue, made from fireclay dust bound with kaolin additives, intended for tiling stoves, fireplaces, and all heated surfaces.

The recommended facing materials are quite varied, the best of them are:

terracotta tiles, they are made from specially fired clay, which gives increased heat resistance and durability;
clinker, denser clay tiles with a surface of various colors, similar to facing bricks;
tiles, also made from clay, having an original embossed surface;
porcelain stoneware made from a mixture of clays, kaolins, quartz sand, feldspars by high-temperature firing under a pressure of 400-500 kg/cm², with imitation of stone, wood, durable artificial material;
soap chloride, a rock mineral consisting of talc, magnesite and chlorite, an environmentally friendly natural material that does not absorb moisture at all, has an attractive appearance, does not crumble, and is not afraid of high temperatures.

Advice! Use soap chloride to finish the steam room, this mineral has a healing effect on the human body, regulates blood pressure, stimulates cerebral circulation, expels viruses and microbes due to the release of vitamin D when heated.

All of the listed tiles are an element of protection that forms a cake, the basis of which is a fire-resistant material. Just like a screen, sheet material is installed on ceramic bushings with a gap of 2-3 cm from the wall. The minimum distance to the heat source from the tile should be 20cm.

Protection with cladding decorates the room, creates a positive mood, and helps to increase the efficiency of procedures. And most importantly, properly installed insulation prevents wooden walls from overheating and catching fire. Have a nice steam!
