Protection and insulation of bathhouse walls from the heat of the stove - rules for constructing protective screens and casings. Installing a stove in a sauna with an external firebox: installing the stove with your own hands How to cover a stove in a sauna

Popularity of private small baths is growing daily. Today, anyone who has even superficial skills in handling tools and experience in construction can build their own bathhouse. Here, as with the construction of any other object, it is important to take all precautions. And protection from the effects of the stove is no exception.

The heat from the stove, spreading throughout the room, harms the upholstery of rooms and furniture. Of course, in large baths this problem does not arise - it is enough to withstand minimum distance from the stove to the walls and to benches, tables and other objects. In rooms where space is limited, it is necessary to use additional protection - special partitions for the stove.

Features and Functions

The protective partition in the bathhouse near the stove is universal subject. Modern manufacturers of such equipment offer many options for barrier screens. New products will suit any needs and different budgets.

The partition plays an important role because it performs the following functions:

  • eliminates the possibility of burns;
  • used as additional room decor;
  • Using a protective partition, you can control the flow of heat not only into the steam room, but throughout the entire house.

Brick baths are in great demand. This material has a fairly low thermal conductivity, so brick walls heat up much more slowly. But such a property does not brick walls in the bathhouse are completely safe - here it is also necessary to protect the walls of the bathhouse from the heat of the stove. Wood is used as the most popular material for building a bathhouse. High temperatures increase the risk of fire.

Use of barrier screens in wooden baths becomes prerequisite.

What materials can be used to create a protective partition?

The enclosure of the stove in the bathhouse is designed to reduce the effects of heat. Brick or metal are used to make it. Each material has its own advantages and is used depending on specific conditions.

Metal partitions

Steel or cast iron are more often used. To provide maximum effect The device must be installed at a distance of 2 cm from the stove. Manufacturers of furnaces and boilers often complete their products with protective partitions. Depending on the purpose, they can be lateral or frontal.

The use of heat-resistant screens allows the stove surface temperature to be reduced to 100°C, due to which the zone of intense heat exposure is reduced by 50 cm. Installing a metal partition yourself is not difficult.

Brick screens

The brick partition is a kind of casing. It completely covers metal surfaces to protect walls from heat. In some cases, brick screens are used as partitions between walls.

Characteristics of a brick partition

To install the screen, just take an ordinary red brick and lay it with mortar. The thickness is half a brick. In some cases, you can use a quarter brick.

Instructions for creating different types of protection from oven heat

A fence for a stove in a steam room made of a sheet of metal will be the most effective and simple solution for a home bath. It is better to use a polished panel, since a smooth, shiny surface is much more reflective. This property also means that heat will not accumulate in the metal, but will spread throughout the room.

The metal fence for the stove in the steam room must be attached to the brickwork or directly to the floor using special fasteners or components. The process will not take much time, but you will completely protect your vacation.

It is necessary to leave a distance between the floor and the metal that will allow air to circulate freely.

The brick partition is laid in half a brick. Here it is also necessary to leave a gap between the floor and the first row. Most often it is made in the form of a door. With its help you can regulate the degree of heat accumulation in the oven.

Start laying from the bottom row, and gradually rise to the height of the stove. The level of the screen should be 15–20 cm higher than the stove. Many experts recommend making such a partition all the way to the ceiling.

Protective non-combustible wall coverings

The wooden walls of the bathhouse are constantly exposed to high temperatures, which in a short period of time leads to their complete wear. You can cover them with thermal insulation materials. They are also divided by type and effectiveness.

Reflective trims

Widely popular metal finish along with thermal insulation. First, it is attached to wooden walls. thermal insulation lining, and then the partition is completed with a sheet of metal. Between them you can place an additional layer of insulation from basalt wool, basalt cardboard, asbestos painting, mineralite and so on.

Fire resistant structures

A special heat-resistant cladding is used as protection for the walls. To do this, the fire-resistant cladding is covered with heat-resistant tiles. Non-flammable glue is used for its installation. The following facing materials have good fire-resistant qualities:

  • terracotta tiles;
  • tiles;
  • porcelain stoneware;
  • soapstone and so on.

In addition, fire-resistant plasterboard, mineralite, glass-magnesium sheet and other fire-resistant boards for a bathhouse can be used as fire-resistant protection for walls. It must be taken into account that for each type it is necessary to provide ventilation in the form of a gap at the bottom. Practice shows that the use of cladding as heat-resistant protection for walls in a bathhouse has almost the same thermal characteristics as reflective cladding. The only drawback is the cost, which is several times higher than standard options.

Protecting the walls of the bathhouse from the heat of the stove requires a careful approach and choice necessary materials. Modern manufacturers already offer ready-made solutions in the form of metal protective screens that are easy to install and use. Brickwork also has high thermal insulation characteristics, so it is also popular.

Great popularity in last years metal stoves have won over home bathhouse owners. The reason for this was the ease and speed of installation, available price policy. However, they have a number of disadvantages, ranging from unpresentable appearance and ending with the likelihood of a fire. The finishing of the stove in the bathhouse is carried out to reduce negative factors.

Decorative finishing of the stove

Distance from wooden wall to stove

Temperature during operation metal furnace in the bath reaches about 400 0. Metal heated to such a temperature can cause a fire in nearby wooden structures. For fire safety purposes, there are permissible distances from a metal heating source to the wall established by SNiP. In the absence of protective screens, the distance should be at least 1 meter.

In large rooms, maintaining such a distance is not difficult. But if the question concerns a small home bath, every centimeter of space is important.
To reduce the permissible distance, a number of measures are taken:


Metal screens

Installation of steel sheets allows you to reduce the fire hazard distance. From wooden surface It is enough to maintain 50 cm to the steel screen.
Protective screens made of metal can be either factory-made or welded independently. When installing, it is necessary between the heating part of the stove and metal screen create a ventilation gap. The presence of a ventilation duct helps heat the casing to 100 0 . Factory screens are equipped with legs and fasteners; using them, installing the sheets will not be difficult.

Brick screens

There are two options for installing a brick screen:

Between a wooden wall and brick screen It is enough to leave a distance of 10-15 cm.


A brick partition is erected only between the wooden wall of the bathhouse and the metal stove

Covering walls with heat-reflecting screens

The reflective lining is thermal insulation material, covered with a sheet on top of stainless steel. This option allows you to reduce the distance from protective coating to the working surface of the oven up to 38 cm.
Non-flammable, durable materials with low thermal conductivity are used as a protective layer that prevents the wooden surface from catching fire:

  • basalt wool(basalt canvas, basalt slabs, basalt cardboard), sometimes called stone wool. Made from rock(basalt), it is environmentally pure material. It does not emit harmful compounds when heated, withstands temperatures up to 600 0 without collapsing or losing its properties. It has good water-repellent ability, does not absorb moisture at all and does not cause corrosion of adjacent materials;
  • mineralite slabs— the main component in them is cement. They are able to withstand temperatures of 600 0, but the operating temperature at which the properties do not change is 150 0. Absorbs and releases moisture well. Minerite is harmless to respiratory tract when heated;


Covering the walls of the bathhouse around the stove with heat-reflecting screens

  • asbestos boards or asbestos cardboard. Some consider it a carcinogenic material that is harmful to health, but this has not been scientifically proven. Asbestos dust can cause harm to the body if inhaled. Covered with a metal sheet on top, asbestos has proven itself to be a good thermal insulation material;
  • expanded vermeculite slabs do not contain asbestos and are made of mountain mica. Have a small specific gravity, high mechanical strength. Such slabs can be coated with a layer of plaster and covered with ceramic tiles.

The heat-insulating layer is covered with a stainless steel sheet on top. In some cases, galvanized iron is used, but it is “transparent” to IR rays. The polished surface of the steel is able to reflect heat rays, directing them back into the bathhouse.

Mount metal sheets on ceramic fasteners that are not subject to strong heat. For free circulation of air flow, preventing heating wooden wall, it is necessary to provide a ventilation gap. To do this, a ventilation gap is provided between the heat-insulating layer and the wall. The screen is mounted, leaving a distance above the floor and above the ceiling.


Sheathing followed by cladding

You can ensure an aesthetically presentable appearance of the bathhouse by decorating the heat-insulating layer with fire-resistant tiles, the installation of which must be done with heat-resistant glue.
To ensure high thermal insulation protection of the wooden surface from the heat of the stove, fire-resistant materials are mounted on it, which can be used as:

  • glass magnetic sheets resistant to high temperatures and high humidity environment. They are characterized by high elasticity and mechanical strength. When heated, they do not emit toxic substances;
  • expanded vermiculite sheets;
  • mineralite slabs.

Facing types: tiles

They have proven themselves well for cladding thermal insulation areas. the following types tiles:

  • Terracotta tiles. Eco-friendly unglazed tiles, made from colored clay without mechanical impurities by prolonged firing in ovens. Has increased heat resistance and does not emit when heated harmful substances and specific odors. During operation it does not lose its original color. It has color palette from gray to beige. It has textured options for wood and stone. Capable long time keep warm.
  • Clinker tiles made from shale clay. It is fired at a temperature of about 1200 0 in one cycle. Does not cause harm to health during the heating process. Such tiles are durable, have increased resistance to abrasion and color loss. The palette of produced colors ranges from black to white.


Facing tiles around the stove in the bathhouse

  • Porcelain tiles. Artificial finishing material consisting of clay, quartz sand and kaolin. Withstands wet environments well and high temperatures, is not destroyed by “thermal shock”. Has a long service life. Manufacturers produce glazed, matte, polished porcelain tiles, structured to resemble leather, wood, and stone.
  • Soapstone tiles. Natural material of mountain origin, most often gray in color, but interspersed with brown, cherry, yellow and green shades. Withstands repeated heating and high humidity, accumulates and releases heat well.

Installation of a brick casing around a metal plate

The brick casing for shielding the furnace has significant weight, and a prerequisite for its installation is the presence of a foundation.

Foundation structure

If the brickwork around a metal stove is made in a bathhouse that has already been built, the floor covering will have to be dismantled.
The size of the concrete base is calculated by adding the size brickwork 20 cm + ventilation gap 10 cm + horizontal dimensions of a metal stove.
Installation begins by selecting a layer of soil. The depth depends on the degree of soil freezing and is about 60 cm.


Reinforcing grid under the stove in the bathhouse

In the case of close groundwater, geotextiles or roofing felt, well coated with bitumen mastic, are laid on the bottom and sides of the pit.
A sand cushion is installed on the base of the resulting pit. The sand is laid wet and compacted thoroughly. A layer of gravel or crushed stone is poured on top and compacted.
Add another layer of sand 15 cm thick.

  • assemble a reinforcing grid from reinforcement or metal rods, with a cell size of 10*10;
  • poured concrete mortar, not reaching the edges of the pit by 10 cm;
  • after this, the concrete needs time to “mature” for three weeks;
  • on top of concrete base lay several layers of roofing felt and install a heat-resistant slab;
  • lay a continuous row of bricks, which should not protrude beyond the boundaries of the refractory sheet; voids in the masonry are also unacceptable. Excess solution is immediately removed;
  • the second row is laid similarly to the first, but with offset seams;
  • observance of the horizontal plane is considered a mandatory condition.

You can purchase a ready-made solution in a store or use a sand-clay mixture. To determine the best ratio of sand and clay, make a small batch from which a cylinder or bar is formed. Pay attention to the possible appearance of cracks, the absence of which is an indicator of quality.


Preparing masonry mortar for a stove in a bathhouse

It is preferable to use clay used for masonry from deep layers, without earthen and mechanical impurities.

To give the clay the required consistency and plasticity, it is kept in water for several days, after which it is ground through a sieve to remove debris.
A 1:1 proportion of clay and sand is considered good; liquid is added to it in small portions.
A high-quality mixture does not stick to the trowel and does not drip from it. When running a trowel over the solution, the mark left behind should not blur or have a torn structure.
To improve the quality of the masonry, add rock salt at the rate of 0.1 kg per bucket of finished mortar. It is also good to add cement and fireclay powder.

Technological process of furnace lining

The laying of a protective casing around a metal plate is carried out:

  • red solid brick, which has high degree heat resistance and long service life;
  • fireclay brick, which has the same characteristics, but a higher cost;


Lining the stove with bricks in the bathhouse

  • ceramic refractory brick: it has all the positive properties solid brick, but at the same time it has a more aesthetic appearance and can be used as a facing brick.

In some cases, masonry is carried out with hollow bricks, but it must be taken into account that it has worse heat retention characteristics.
It is advisable to soak the brick before starting work. Dry brick is able to quickly absorb the liquid fraction through capillaries and does not allow the binding part of the solution to penetrate inside to increase the adhesion of the masonry. In the summer, this method is not difficult.

If the construction process takes place in the autumn-spring period, in cold, damp weather, dry the wet brick in finished product quite problematic. Heating for drying means dealing a blow to the strength even before the stove starts operating: uneven heating will destroy the seams. It is also impossible to leave the stove undried over the winter; the cold will tear the masonry under the influence of negative temperatures. In this case, make a more liquid solution and slightly wet the surface of the brick.
In case of insufficient construction experience To make it easier to maintain a horizontal plane, stretch a cord or fishing line around the perimeter of the masonry. Inconvenience this method consists in the need to raise the fishing line with each row.


Usually the masonry is finished flush with the level of the slab, but in some cases the pipe is also hidden to give a presentable appearance

  • A metal oven can be temporarily insulated with polyethylene to avoid contamination.
  • Laying the row begins from the corner. Most often, they use half-brick masonry, placing each one on a bed (flat). To save money, they are sometimes placed on a spoon (edge).
  • The thickness of all seams should be the same with good filling with mortar.
  • Each row is laid with reinforcing mesh to increase the strength of the masonry.
  • The second row also starts from the corner, but uses the first half of the brick to offset the seams.

During the heating of the bath, the surface of the stove heats up to 300-400°C. At the same time, it begins to emit infrared rays and itself becomes a source of heating. The coming heat is distributed throughout the steam room, but first of all it hits the walls adjacent to the stove. If the walls are wooden, then under the influence of high temperatures their charring begins. And there it’s already a stone’s throw away! The only one for real effective method insulating wooden walls from heat - creating protective screens and cladding from non-combustible materials in the bathhouse.

When is protection needed at all?

The need to install protective casings and screens does not always arise. If a fire-safe distance is maintained between the stove and the nearest flammable surface, additional protection is not needed. At this distance, the IR rays are scattered, weakened, and the amount of them that the wooden wall receives can no longer lead to damage.

It is believed that the safe distance from the wall to brick oven(quarter brick laying) is at least 0.32 m, from the wall to (not lined) - at least 1 m. For a metal stove lined from the inside with brick or fireclay, the distance is reduced to 0.7 m.

Thus, maintaining fire safety distances is more possible in large baths, where the issue of saving space is not relevant. In family steam rooms, where every centimeter of space counts, installing a stove 0.3-1 m from the nearest walls is impractical. In this case, the safety distances established by the standards must be reduced using screens and casings.

Protective screens near (around) the stove

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

Method #1 - metal screens

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.

Method #2 - brick screens

A brick screen can cover all the side surfaces of a metal furnace, representing it outer skin. 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.

For laying the protective screen, use solid fireclay brick. Binder – cement or clay mortar. It is recommended to use half a brick (thickness 120 mm). But, if there is a lack of material, it is possible to make a wall of a quarter of a brick (60 mm thick), although in this case the thermal insulation properties of the screen will be reduced by half.

Small openings (sometimes with fire doors) are left at the bottom of the shield for air convection between brick wall and a stove.

The brick walls of the screen must end at least 20 cm above the top surface of the oven. Sometimes the masonry goes all the way to the ceiling.

The brick screen is not installed flush against the walls of the stove, the optimal distance is 5-15 cm. The acceptable distance from the brickwork to the flammable wall is 5-15 cm. Thus, the use of a brick screen allows you to reduce the distance from the stove to the wooden wall to 22-42 cm (stove - ventilation gap 5-15 cm - brick 12 cm - ventilation gap 5-15 cm - wall).

Protective non-combustible wall coverings

Walls adjacent to the hot furnace walls are susceptible to spontaneous combustion. To prevent their overheating, special casings consisting of heat-insulating and non-combustible materials are used.

Option #1 - reflective trim

Effective are claddings consisting of a combination non-combustible thermal insulation and metal sheets. In this case, thermal insulation is attached to the wooden surface, which is covered with a stainless steel sheet on top. Some use galvanizing for these purposes, but, according to some data, when heated, it can release harmful substances. It’s better not to risk it and buy a stainless steel sheet.

For greater efficiency, the metal sheet of the screen must be well polished. The mirror surface helps to reflect heat rays from the wooden surface and, accordingly, prevents its heating. In addition, a stainless steel sheet, directing IR rays back into the steam room, transforms hard radiation into softer radiation, better perceived by humans.

The following can be fixed under stainless steel as thermal insulation:

  • Basalt wool - it has high thermal insulation properties, absolutely safe when used in a bath. It has increased hygroscopicity and does not burn.
  • Basalt cardboard is thin sheets of basalt fiber. Used as a fireproof, sound and heat insulating material.
  • Asbestos cardboard is a sheet fire-resistant heat insulator. Possesses high strength and durability, protects flammable surfaces from ignition.
  • Minerite is a non-flammable sheet (plate) specially manufactured for shielding stoves, fireplaces, and easily flammable surfaces in baths and saunas.

A popular example of cladding using a metal sheet is this “pie”: wall – ventilation gap (2-3 cm) – insulation (1-2 cm) – stainless steel sheet. The distance from the wooden wall to the stove is at least 38 cm (SNiP 41-01-2003).

Ceramic bushings are used to attach the sheathing to the wall. They do not heat up and allow the formation of ventilation gaps between the thermal insulation and the wall.

If the distance between the wooden wall and the stove is minimal, then the cladding is made of two layers of fire-resistant insulation, for example, mineralite. In this case, the sheets are fixed through ceramic bushings maintaining a gap of 2-3 cm. Top sheet closed with stainless steel.

Option #2 - sheathing with cladding

Of course, protective cladding with stainless steel perfectly protects wooden walls from heat and fire. But it can spoil the impression of the most expensive finish. Therefore, if the steam room is designed in a decorative style, the fire-resistant lining is masked with heat-resistant tiles. The tiles are laid on heat-resistant adhesive, for example, produced by Terracotta.

The best materials for cladding walls near the stove:

  • Terracotta tiles are made from baked clay. It is characterized by strength, heat resistance, durability. Terracotta tiles can be matte or glazed (majolica), and the color varies from pastel yellow to brick red.
  • Clinker tiles - also made of clay, similar in appearance to facing brick. Unlike terracotta, clinker tiles are denser. The color range covers almost all colors, ranging from white to black, including green and blue tones, unusual for clay.
  • Tiles - a variety ceramic tiles. It usually has embossing on the front surface in the form of a design or ornament.
  • Porcelain tiles – heat-resistant, durable tiles. Depending on the method of processing the front surface, tiles can imitate natural stone, brick, or wood. IN color scheme– all natural shades, from white to black.
  • Soapstone is a rock of grayish or greenish color. It is fireproof, waterproof and durable.

Attaching fire-resistant tiles directly to walls will not have any thermal insulation effect. The wall will still heat up, which can lead to spontaneous combustion. Therefore, tiles are used only as an element of a protective “pie” of the following design: wall – ventilation gap (2-3 cm) – fireproof sheet material- tile. It is recommended to maintain a minimum distance of 15-20 cm from the tiles to the walls of the oven.

Any material from this list can be used as a fire-resistant element in the cladding:

  • Fire-resistant drywall (GKLO) is drywall supplemented with fiberglass fibers. Resists thermal effects without structural deformation.
  • Minerite is a cement-fiber board, absolutely non-flammable. Minerite slabs are moisture resistant, do not rot, and do not decompose.
  • Glass-magnesium sheet (FMS) is a material in the form of plates made on the basis of magnesium binder and fiberglass. Has warmth and soundproofing properties, does not collapse under the influence of water and temperature changes.

The protective cladding, which must comply with the ventilation gap, has a very low heat absorption coefficient, so the wall underneath it practically does not heat up. In addition, the use of cladding allows you to disguise the protective “pie” and maintain the finishing of the steam room in the same style.

Choosing a finish for a sauna stove is not as easy as it seems. A mistake can be costly. Incorrectly chosen material near the stove will crack and collapse from high temperature. It is not safe. The purpose of the cladding, in addition to its decorative function, is to minimize the likelihood of accidental injury.

Collapse

How can you decorate a stove in a bathhouse?

First of all, this is:

  • ceramic tiles,
  • brick,
  • different types of stone,
  • plastering with a special solution,
  • steel,
  • tiles.

As you can see, the choice of materials is quite wide. Each of these materials must have certain properties and undergo special processing to withstand the high temperature near the furnace. Let's look at each of them in more detail.

Using tiles

The tiles on the stove in the bathhouse are afraid of thermal expansion, therefore, when performing work, it is important to carefully follow the technological process. The lining of the stove in the bathhouse does not tolerate negligence.

Kinds

Typically, 7 types of tiles are used for cladding:

  • Terracotta is a tile that has not been glazed. It consists of terracotta clay and fireclay, which are mixed in a certain ratio. Such tiles have been known for several centuries. A correctly implemented technological process greatly influences the final quality of the material. This tile can be easily recognized by its characteristic red tint.
  • Clinker tiles - clay is the main raw material. The material is obtained by pressing, then it is fired at a temperature of +1200 0 C. The crystal lattice of the clay changes and the tile acquires the properties of ceramics.
  • Majolica is very difficult to produce. Previously, only manual labor was used for drawing. Now there are industrial designs. The glaze on the tile is obtained by firing. Properties resemble terracotta tiles.
  • Tiles are the most preferred option, thanks to air gap between the tile and the oven wall. This layer works as an additional heat insulator, allowing the stove to retain heat near itself even longer.
  • Porcelain stoneware - can also be used for lining the stove. Marble chips, added during the production of porcelain stoneware, gives the material unique decorative properties and high strength. Due to this, porcelain tiles are rapidly gaining popularity.
  • Fireclay - able to withstand direct exposure to fire. Fireclay is pressed into blanks and fired at a temperature of +1300 0 C.
  • Tile - only material with high coefficient heat resistance will be able to withstand temperature loads.

Expert opinion

Stove maker with 15 years of experience

Based on their properties, the most preferable option for lining a stove is tiles. It is also the most labor-intensive. Most a budget option- special tile with a high coefficient of heat resistance, but with its help it will not be possible to finish the hottest areas.

Instructions

Facing sauna stove Do-it-yourself tiles are done as follows:


Finishing the stove with bricks

Traditionally, the stove lining is made with brick. This material is also suitable for wooden walls near the stove. It is an additional heat accumulator.

At the same time, the brick acts as a protective screen that prevents burns and has a presentable appearance. You can also line a metal stove with bricks.

Kinds

The following types of bricks are used for cladding the stove:


It is not recommended to use silicate and hollow bricks. It will not hold heat well and will collapse. Fireclay brick is preferable to use, but it is more expensive.

Instructions

  1. The laying is done using a mortar specially designed for ovens. It will ensure optimal structural strength.
  2. The foundation design must be designed to withstand such a load. Otherwise, you will have to make a separate foundation.
  3. The masonry is done in half a brick. The brick is placed on the bed. We start laying from the corner, bandaging 1/3.
  4. For heat exchange, ventilation holes must be provided in the masonry.
  5. Between the rows we reinforce the masonry with mesh.
  6. After completing the masonry, we perform jointing.

Using plaster

Plaster is the most budget-friendly option for finishing a stove with your own hands. The product takes on a finished look and looks good in the interior. After plastering, you can whitewash it with a special heat-resistant compound.

This type of finishing is quite often used for brick ovens. The technology is as follows:


Tiles

A stove with tiles is a rather labor-intensive process. Technology has simplified things a bit. But it still takes 4-5 months to build such a furnace, if you use classic version. The laying and lining of the furnace occurs simultaneously. Although, in a simplified version, you can line a finished stove.

Expert opinion

Nikolay Davydov

Stove maker with 15 years of experience

The drawing can be anything. Usually Russian folk motifs are used. The sizes of tiles are regulated by GOST 3742-47. Permissible deviations should not exceed 1 mm in all directions. Thanks to standardization, the cladding process has been significantly simplified. The most important thing is to choose the right material.

Instructions

You should be guided by the following rules:

  1. Material of manufacture. Impurities in colored clay will not allow the production of high-quality tiles, so it is not used. In contrast, white clay is an ideal raw material.
  2. The quality of a product is determined by its ability to absorb water. The more pores in a tile and the larger they are, the less quality the product will be.
  3. Choose tiles made by pressing.
  4. The surface of the product should not have a dull appearance and there should be no cracks on it. This happens when a product undergoes only one firing.

For cladding, tiles must be sorted by shade. They will need to be laid in such a way that the transition is not noticeable. The size is adjusted using a rasp and an angular grinder from all sides. Defective tiles should not be thrown away immediately. They can be used later.

The next step is to mark. The thickness of the horizontal seam should not exceed 3 mm, vertical - 1 mm. Now let's move on to installation.

Lay out the first row.

The process is very labor-intensive, but the result is worth it. The first thing to do is to properly prepare the tiles for installation. This will ensure the best result.

The installation order is as follows:

  • immerse the tiles in water, waiting until the clay absorbs water;
  • the clay in the tiller will increase the heat capacity, so you need to fill it halfway;
  • steel brackets allow you to correctly connect the tiles to each other;
  • We connect a row of tiles to a row of the stove using wire.

Scheme for fastening the tiles: 1 – lump, 2 – pin, 3 – wire, 4 – staples.

Subsequent rows.

  • drill holes in the masonry;
  • We use screws and wire as a connecting element;
  • We fasten the steel pins using wire;
  • we place the tile on the pin and bend the last one;
  • the dry solution will fill all the voids between the tiles.

Sauna stove in tiles

Conclusion

The choice of this or that material for lining the stove in the bathhouse is determined by the result that needs to be obtained in the end. The most interesting option in terms of heat preservation is tiling, but it is also the most labor-intensive and expensive. If you want to veneer your stove cheaply, there is such an opportunity.

The most budget option is plastering the stove. It is best to line a metal stove with bricks. This will significantly increase the heat capacity of the oven and it will take longer to cool down.

Another great option- porcelain stoneware. When deciding how to line a stove in a bathhouse, pay attention to the quality of the materials used.

To insulate the space around the stove, it is advisable to use mineralite. This is an excellent sauna cover. They are used for lining the sauna - covering wooden walls, although these slabs can also be used to cover a house.

Using step by step instructions of this article, you can not only choose the right material in the best possible way, but also to do the lining of the stove itself and its surfaces with your own hands. This became the main purpose of this material.

What is the best way to decorate a wall in a sauna? wood stove? Welded metal stove, metal 4mm thick. From the stove to the wall about 20-25cm. The best way to finish the wall is to prevent the lining from charring and catching fire. Are soapstone or coil slabs suitable? And is it possible to glue them directly to the lining?

You're right. For the safe operation of a metal stove, the distance you specified (20-25cm) to the wooden surface of the wall is not enough. Metal stoves are characterized by active thermal radiation, at peak moments the firebox becomes red from heating. A wooden wall surface or ceiling partition, when heated to 100 °C, is guaranteed to ignite. This is especially true for wood in a steam room, where it is constantly dried until minimum values humidity.

One of ideal options for a metal stove in a bathhouse is shown in the photo. The oven is partially covered with brick on three sides, which allows for additional heat accumulation. There is also a screen made of fireproof material installed on the wall. This can be a layer of basalt cardboard or cotton wool, with a galvanized sheet on top of it.

Double wall protection

It is better to connect the heat-insulating material of the screen with “grooves”.

Combining thermal insulation joints

Soapstone is excellent decorative material. It is most often used for lining stoves and fireplaces, and sometimes even for laying stoves. Its main advantages in our case become disadvantages. This material perfectly accumulates and transfers heat, as evidenced by the heating of the surface on which it is installed. Therefore, if your choice fell on this stone, we can offer to replace part of the wall (or flammable internal lining) brick. It can even be decorative. And in this area it is already possible to lay soapstone tiles on heat-resistant adhesive for lining stoves and fireplaces.

The same recommendations apply to products made from coils. If done well, this protection option will not only look harmonious and be the highlight of the sauna, but will also provide you with almost 100% fire safety.

Protecting walls in a bathhouse from stove heat: how to properly make a protective screen or casing

When you heat the bathhouse for procedures, the surface of the oven can heat up to 300-400 degrees. In the process she emits infrared rays and itself becomes a source of heating. The radiated heat is distributed throughout the steam room, but first it touches the walls, which are located near the wall. If the walls in your steam room are made of wood, then due to the high temperature they will begin to char. And this can cause fire and fire. Despite how they advertise different means to protect the tree and other options for eliminating this problem, the most effective method isolation was and remains the arrangement of a protective screen and casing made of non-flammable materials.

In what situations is wall protection needed?

There are situations when protecting the walls near the stove is not necessary. For example, if between the stove and the closest surface there is a safe distance from the point of view of fire regulations. This distance should be enough to disperse the infrared rays so that they weaken and do not damage the wall.

fire safe distance from a metal stove to the walls of the bathhouse

The safe distance from the wall is:

  • to a brick stove (with ¼ brick masonry) - no less than 0.32 m;
  • to a non-lined metal furnace - at least 1 m.
  • to a metal furnace lined inside with brick or fireclay - no less than 0.7 m.

Such a safe, fire-safe distance can generally only be organized in steam rooms with impressive parameters. In smaller family-type steam rooms, when there is a need to save every centimeter, installing a stove at such a distance is not a justifiable luxury. Therefore, for such small steam rooms, it is better to use screens or special cladding to protect the walls.

Protective screen around the oven.

Shields are insulating shields that cover the sides of the oven and reduce the intensity of heat rays. Screens can be made of brick or metal. They are mainly used for metal stoves.

Option No. 1 – metal screen.

The most commonly used protective screen is made of steel or cast iron sheets, which is bought ready-made. It is mounted around the stove at a distance of 1-5 cm from the walls of the firebox. There are side and front screens, choose depending on which side of the stove you need to cover. Manufacturers often make furnaces already equipped with a screen - a casing.

bathhouse wall protection - metal screen

The protective screen makes it possible to reduce the temperature of the external surfaces of the stove to 80-100 degrees, thereby reducing the safe distance to 50 cm. As a result, the distance from the firebox to the wall, including an installation gap of 1-5 cm, will be 51-55 cm. Install The protective screen is not complicated, it is usually equipped with legs that simply need to be bolted to the floor.

Option No. 2 – protective screen made of brick.

With such a screen you can cover all the side parts of the stove, thus making an outer lining for it. As a result, the stove will stand in a brick casing.

Or you can simply separate the oven and the fire-hazardous surface with such a screen.

The material for the screen used as wall protection is solid fireclay brick. For the binder, take a solution made of cement or clay. Craftsmen advise making masonry in half a brick (12 cm thick). But if you don’t have enough material, you can make a screen in ¼ brick (6 cm), but this will lead to a reduction in the thermal insulation performance of the protective wall by half. And then you need to take such changes into account when calculating the safe distance.

bathhouse wall protection - brick screen

When laying, you need to leave small holes in the lower part (sometimes with fire doors). They will serve to create air exchange in the space between the stove and the screen.

The height of the brick screen should exceed the height of the stove by at least 20 cm. There are cases when the protective screen is laid out up to the ceiling.

Such a screen is not made close to the stove - you need to leave 5-15 cm. In order for the walls to be protected reliably, the optimal distance between the screen and the wall should be from 5 to 15 cm. Using a protective brick screen, you can reduce the distance from the stove to the wall to 22- 42 cm (stove + gap 5-15 cm + brick -12 cm + gap 5-15 cm + wall),

Non-combustible wall cladding for protection.

Any wall that is adjacent to a hot stove is not immune to spontaneous combustion. To prevent overheating of the walls, it is recommended to use special sheathing, which consists of heat-insulating and non-combustible materials.

Construction of a bathhouse

Sheathing, which includes non-combustible thermal insulation and metal sheets, has proven itself to be excellent. So, you need to attach a heat-insulating material to a wooden surface, and then a stainless steel sheet on top of it. Some people use galvanized steel, but there is information that when heated, it can release harmful substances. So it is better to use stainless steel.

To increase the effectiveness of such cladding, you need to polish the metal sheet well. The specularity of the surface will improve the reflection of heat rays from the wood and naturally prevent its heating. Another advantage is that by redirecting hard IR rays back into the steam room, stainless metal makes them softer and people perceive them more easily.

reflective wall cladding

You can install the following thermal insulation material under a sheet of metal:

  • Basalt wool - it has high thermal insulation and increased hygroscopicity. It is safe even in extreme steam room conditions, and it does not burn.
  • Basalt cardboard is basalt fiber in the form of thin sheets. Fireproof, sound and heat insulating material.
  • Asbestos cardboard is a fire-resistant heat-insulating material in sheets. It is characterized by excellent strength, durability and the ability to protect surfaces prone to fire from ignition.
  • Minerite is a non-flammable slab that is made specifically for creating screens near stoves, fireplaces and other surfaces in a bathhouse or sauna that can easily catch fire.

The following cladding scheme is popular:

Wall – ventilation gap 2-3cm. – insulation 1-2 cm. – metal sheet. The safe distance from the stove to the wall will be at least 38 cm.

Ceramic bushings are used to secure the sheathing to the wall. They do not heat up and additionally serve to create a ventilation gap between the wall and the layer of heat-insulating material.

If you were unable to install the stove at a safe distance, then you need to cover it with two layers of heat-insulating material. In this option, the sheets are secured through bushings, maintaining a gap of 2-3 cm, and the top sheet is covered with a metal sheet.

Russian bath project

Reflective cladding is an excellent protection for wood walls from heat and fire, but it may not always look beautiful or appropriate in a steam room. If you have a steam room with a certain design or decor, you can disguise such cladding with heat-resistant tiles. To lay such tiles you need to use heat-resistant adhesive.

Wall protection near the stove with lining can be made of the following materials:

  • Terracotta tiles are made from fired clay and have excellent strength, heat resistance and service life. Terracotta can be matte or glazed, with shades ranging from pastel yellow to brick red.
  • Clinker tiles are clay tiles similar to facing bricks. Its structure is denser than that of terracotta. The color may be your favorite, even white or black, or something completely unusual for tiles - blue or green.
  • Tiles are a type of ceramic tile. Characteristic– embossing in the form of a pattern or ornament on the front part.
  • Porcelain tiles are tiles of increased strength and heat resistance. Different way front side processing forms different surface. Porcelain tiles can imitate stone, brick or wood. The color palette includes natural shades, from white to black.
  • Soapstone is a natural mountain stone of gray or green hue. Distinctive features: fire resistance, water resistance, strength.

protective cladding with cladding

Using fire resistant tiles to cover a wall will not provide thermal insulation. The walls will heat up anyway. The tile serves only one component in this design:

Wall – ventilation gap 2-3 cm. – fire-resistant material in sheets – tiles. The distance from the stove to the tiles should be at least 15-20 cm.

Refractory material can be:

  • Fire-resistant drywall (GKLO) is a drywall containing fiberglass. It does not deform under the influence of heat.
  • Minerite is a non-flammable cement-fiber board. In addition, it is moisture resistant and not subject to rotting or decomposition.
  • Glass-magnesium sheet (GML) is a slab material that contains fiberglass and magnesium binder. This material is famous for its heat and sound insulation properties, and its resistance to temperature changes and the influence of water.

If the wall protection is carried out in compliance with all the rules and the organization of a ventilation gap, then such cladding will have a low heat absorption rate, and the wall will hardly heat up. In addition, the use of tiles for cladding will camouflage well protective layer, and you will not spoil the style and design of the steam room.

Protecting walls in a bathhouse from stove heat: how to properly make a protective screen or casing


protecting the walls of the bathhouse from the heat of the stove. Why is it needed and what is the fireproof distance from the walls to the stove. Protective screens, protective sheathing and sheathing with cladding

Protecting the walls of the bathhouse from the heat of the stove: rules for constructing protective screens and casings

During the heating of the bath, the surface of the stove heats up to 300-400°C. At the same time, it begins to emit infrared rays and itself becomes a source of heating. The coming heat is distributed throughout the steam room, but first of all it hits the walls adjacent to the stove. If the walls are wooden, then under the influence of high temperatures their charring begins. And there it’s already a stone’s throw away! The only truly effective way to insulate wooden walls from heat is to create protective screens and cladding from non-combustible materials in the bathhouse.

When is protection needed at all?

The need to install protective casings and screens does not always arise. If a fire-safe distance is maintained between the stove and the nearest flammable surface, additional protection is not needed. At this distance, the IR rays are scattered, weakened, and the amount of them that the wooden wall receives can no longer lead to damage.

It is believed that the safe distance from the wall to the brick stove (quarter-brick laying) is at least 0.32 m, from the wall to the metal stove (not lined) - at least 1 m. For a metal stove lined from the inside with brick or fireclay, the distance decreases to 0.7 m.

Thus, maintaining fire safety distances is more possible in large baths, where the issue of saving space is not relevant. In family steam rooms, where every centimeter of space counts, installing a stove 0.3-1 m from the nearest walls is impractical. In this case, the safety distances established by the standards must be reduced using screens and casings.

Protective screens near (around) the stove

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.

Method #1 - metal screens

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.

Method #2 - brick screens

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.

To lay the protective screen, solid fireclay bricks are used. The binder is cement or clay mortar. It is recommended to use half a brick (thickness 120 mm). But, if there is a lack of material, it is possible to make a wall of a quarter of a brick (60 mm thick), although in this case the thermal insulation properties of the screen will be reduced by half.

Small openings (sometimes with fire doors) are left at the bottom of the shield for air convection between the brick wall and the stove.

The brick walls of the screen must end at least 20 cm above the top surface of the oven. Sometimes the masonry goes all the way to the ceiling.

The brick screen is not installed flush against the walls of the stove, the optimal distance is 5-15 cm. The acceptable distance from the brickwork to the flammable wall is 5-15 cm. Thus, the use of a brick screen allows you to reduce the distance from the stove to the wooden wall to 22-42 cm (stove - ventilation gap 5-15 cm - brick 12 cm - ventilation gap 5-15 cm - wall).

Protective non-combustible wall coverings

Walls adjacent to the hot furnace walls are susceptible to spontaneous combustion. To prevent their overheating, special casings consisting of heat-insulating and non-combustible materials are used.

Option #1 - reflective trim

Sheathing consisting of a combination of non-combustible insulation and metal sheets is effective. In this case, thermal insulation is attached to the wooden surface, which is covered with a stainless steel sheet on top. Some use galvanizing for these purposes, but, according to some data, when heated, it can release harmful substances. It’s better not to risk it and buy a stainless steel sheet.

For greater efficiency, the metal sheet of the screen must be well polished. The mirror surface helps to reflect heat rays from the wooden surface and, accordingly, prevents its heating. In addition, a stainless steel sheet, directing IR rays back into the steam room, transforms hard radiation into softer radiation, better perceived by humans.

The following can be fixed under stainless steel as thermal insulation:

  • Basalt wool - it has high thermal insulation properties and is absolutely safe when used in a bathhouse. It has increased hygroscopicity and does not burn.
  • Basalt cardboard is thin sheets of basalt fiber. Used as a fireproof, sound and heat insulating material.
  • Asbestos cardboard is a sheet fire-resistant heat insulator. It has high strength and durability, protects flammable surfaces from ignition.
  • Minerite is a non-flammable sheet (plate) specially manufactured for shielding stoves, fireplaces, and easily flammable surfaces in baths and saunas.

A popular example of cladding using a metal sheet is this “pie”: wall – ventilation gap (2-3 cm) – insulation (1-2 cm) – stainless steel sheet. The distance from the wooden wall to the stove is at least 38 cm (SNiP 41-01-2003).

Ceramic bushings are used to attach the sheathing to the wall. They do not heat up and allow the formation of ventilation gaps between the thermal insulation and the wall.

If the distance between the wooden wall and the stove is minimal, then the cladding is made of two layers of fire-resistant insulation, for example, mineralite. In this case, the sheets are fixed through ceramic bushings, maintaining a gap of 2-3 cm. The top sheet is covered with stainless steel.

Option #2 - sheathing with cladding

Of course, protective cladding with stainless steel perfectly protects wooden walls from heat and fire. But it can spoil the impression of the most expensive finish. Therefore, if the steam room is designed in a decorative style, the fire-resistant lining is masked with heat-resistant tiles. The tiles are laid on heat-resistant adhesive, for example, produced by Terracotta.

The best materials for cladding walls near the stove:

  • Terracotta tiles are made from baked clay. It is characterized by strength, heat resistance, durability. Terracotta tiles can be matte or glazed (majolica), and the color varies from pastel yellow to brick red.
  • Clinker tiles are also made of clay and look similar to facing bricks. Unlike terracotta, clinker tiles are denser. The color range covers almost all colors, ranging from white to black, including green and blue tones, unusual for clay.
  • Tiles are a type of ceramic tile. It usually has embossing on the front surface in the form of a design or ornament.
  • Porcelain tiles are heat-resistant, durable tiles. Depending on the method of processing the front surface, tiles can imitate natural stone, brick, or wood. The color range includes all natural shades, from white to black.
  • Soapstone is a rock of grayish or greenish color. It is fireproof, waterproof and durable.

Attaching fire-resistant tiles directly to walls will not have any thermal insulation effect. The wall will still heat up, which can lead to spontaneous combustion. Therefore, tiles are used only as an element of a protective “pie” of the following design: wall – ventilation gap (2-3 cm) – fire-resistant sheet material – tiles. It is recommended to maintain a minimum distance of 15-20 cm from the tiles to the walls of the oven.

Any material from this list can be used as a fire-resistant element in the cladding:

  • Fire-resistant drywall (GKLO) is drywall supplemented with fiberglass fibers. Resists thermal effects without structural deformation.
  • Minerite is a cement-fiber board, absolutely non-flammable. Minerite slabs are moisture resistant, do not rot, and do not decompose.
  • Glass-magnesium sheet (FMS) is a material in the form of plates made on the basis of magnesium binder and fiberglass. It has heat and sound insulating properties and is not destroyed by water and temperature changes.

The protective cladding, which must comply with the ventilation gap, has a very low heat absorption coefficient, so the wall underneath it practically does not heat up. In addition, the use of cladding allows you to disguise the protective “pie” and maintain the finishing of the steam room in the same style.

Protecting the walls of the bathhouse from the heat of the stove: installing protective sheathing and screens


Let's figure out how to protect the walls of the bathhouse from the heat of the stove. Installation of protective casings and special screens. Technical rules fire safety.

How to decorate a stove in a bathhouse

Metal stoves have gained great popularity among home bath owners in recent years. The reason for this was the ease and speed of installation and affordable pricing. However, they have a number of disadvantages, ranging from unpresentable appearance to the likelihood of a fire. The finishing of the stove in the bathhouse is carried out to reduce negative factors.

During operation, the temperature of the metal furnace in the bath reaches about 400 0. Metal heated to such a temperature can cause a fire in nearby wooden structures. For fire safety purposes, there are permissible distances from a metal heating source to the wall established by SNiP. In the absence of protective screens, the distance should be at least 1 meter.

In large rooms, maintaining such a distance is not difficult. But if the question concerns a small home bath, every centimeter of space is important.

To reduce the permissible distance, a number of measures are taken:

  • install protective screens around the stove itself;
  • sheathe sections of walls located in close proximity to the source of ignition.

Metal screens

Installation of steel sheets allows you to reduce the fire hazard distance. From the wooden surface to the steel screen it is enough to maintain 50 cm.

Protective screens made of metal can be either factory-made or welded independently. During installation, it is necessary to create a ventilation gap between the heating part of the stove and the metal screen. The presence of a ventilation duct helps heat the casing to 100 0 . Factory screens are equipped with legs and fasteners; using them, installing the sheets will not be difficult.

Brick screens

There are two options for installing a brick screen:

  • a brick partition is erected only between the wooden wall of the bathhouse and the metal stove;
  • The oven is covered with brick walls on all sides.

It is enough to leave a distance of 10-15 cm between the wooden wall and the brick screen.

Covering walls with heat-reflecting screens

Reflective cladding is a heat-insulating material covered with a stainless steel sheet on top. This option allows you to reduce the distance from the protective coating to the working surface of the oven to 38 cm.

Non-flammable, durable materials with low thermal conductivity are used as a protective layer that prevents the wooden surface from catching fire:

  • basalt wool(basalt canvas, basalt slabs, basalt cardboard), sometimes called stone wool. Made from rock (basalt), it is an environmentally friendly material. It does not emit harmful compounds when heated, withstands temperatures up to 600 0 without collapsing or losing its properties. It has good water-repellent ability, does not absorb moisture at all and does not cause corrosion of adjacent materials;
  • mineralite slabs- the main component in them is cement. They are able to withstand temperatures of 600 0, but the operating temperature at which the properties do not change is 150 0. Absorbs and releases moisture well. Minerite is harmless to the respiratory tract when heated;

  • asbestos boards or asbestos cardboard. Some consider it a carcinogenic material that is harmful to health, but this has not been scientifically proven. Asbestos dust can cause harm to the body if inhaled. Covered with a metal sheet on top, asbestos has proven itself to be a good thermal insulation material;
  • expanded vermeculite slabs do not contain asbestos and are made of mountain mica. They have low specific gravity and high mechanical strength. Such slabs can be coated with a layer of plaster and covered with ceramic tiles.

The heat-insulating layer is covered with a stainless steel sheet on top. In some cases, galvanized iron is used, but it is “transparent” to IR rays. The polished surface of the steel is able to reflect heat rays, directing them back into the bathhouse.

Metal sheets are mounted on ceramic mounts that are not subject to strong heat. For free circulation of air flows, preventing heating of the wooden wall, it is necessary to provide a ventilation gap. To do this, a ventilation gap is provided between the heat-insulating layer and the wall. The screen is mounted, leaving a distance above the floor and above the ceiling.

Sheathing followed by cladding

You can ensure an aesthetically presentable appearance of the bathhouse by decorating the heat-insulating layer with fire-resistant tiles, the installation of which must be done with heat-resistant glue.

To ensure high thermal insulation protection of the wooden surface from the heat of the stove, fire-resistant materials are mounted on it, which can be used as:

  • glass magnetic sheets, resistant to high temperatures and high humidity. They are characterized by high elasticity and mechanical strength. When heated, they do not emit toxic substances;
  • expanded vermiculite sheets;
  • mineralite slabs.

Facing types: tiles

The following types of tiles have proven themselves well for cladding thermal insulation areas:

  • Terracotta tiles. Eco-friendly unglazed tiles made from colored clay without mechanical impurities through long-term firing in ovens. It has increased heat resistance and does not emit harmful substances or specific odors when heated. During operation it does not lose its original color. It has a color palette from gray to beige. It has textured options for wood and stone. Able to retain heat for a long time.
  • Clinker tiles made from shale clay. It is fired at a temperature of about 1200 0 in one cycle. Does not cause harm to health during the heating process. Such tiles are durable, have increased resistance to abrasion and color loss. The palette of produced colors ranges from black to white.

  • Porcelain tiles. Artificial finishing material consisting of clay, quartz sand and kaolin. It withstands humid environments and high temperatures well and is not destroyed by thermal shock. Has a long service life. Manufacturers produce glazed, matte, polished porcelain tiles, structured to resemble leather, wood, and stone.
  • Soapstone tiles. A natural material of mountain origin, often gray in color, but interspersed with brown, cherry, yellow and green shades. Withstands repeated heating and high humidity, accumulates and releases heat well.

Installation of a brick casing around a metal plate

The brick casing for shielding the furnace has significant weight, and a prerequisite for its installation is the presence of a foundation.

Foundation structure

If the brickwork around a metal stove is made in a bathhouse that has already been built, the floor covering will have to be dismantled.

The size of the concrete base is calculated by adding the size of the brickwork 20 cm + ventilation gap 10 cm + horizontal dimensions of the metal furnace.

Installation begins by selecting a layer of soil. The depth depends on the degree of soil freezing and is about 60 cm.

In the case of close groundwater, geotextiles or roofing felt, well coated with bitumen mastic, are laid on the bottom and sides of the pit.

A sand cushion is installed on the base of the resulting pit. The sand is laid wet and compacted thoroughly. A layer of gravel or crushed stone is poured on top and compacted.

Add another layer of sand 15 cm thick.

  • assemble a reinforcing grid from reinforcement or metal rods, with a cell size of 10*10;
  • pour concrete mortar, not reaching the edges of the pit by 10 cm;
  • after this, the concrete needs time to “mature” for three weeks;
  • several layers of roofing material are laid on top of the concrete base and a heat-resistant slab is installed;
  • lay a continuous row of bricks, which should not protrude beyond the boundaries of the refractory sheet; voids in the masonry are also unacceptable. Excess solution is immediately removed;
  • the second row is laid similarly to the first, but with offset seams;
  • observance of the horizontal plane is considered a mandatory condition.

Preparation of mortar for masonry

You can purchase a ready-made solution in a store or use a sand-clay mixture. To determine the best ratio of sand and clay, make a small batch from which a cylinder or bar is formed. Pay attention to the possible appearance of cracks, the absence of which is an indicator of quality.

It is preferable to use clay used for masonry from deep layers, without earthen and mechanical impurities.

To give the clay the required consistency and plasticity, it is kept in water for several days, after which it is ground through a sieve to remove debris.

A 1:1 proportion of clay and sand is considered good; liquid is added to it in small portions.

A high-quality mixture does not stick to the trowel and does not drip from it. When running a trowel over the solution, the mark left behind should not blur or have a torn structure.

To improve the quality of the masonry, add rock salt at the rate of 0.1 kg per bucket of finished mortar. It is also good to add cement and fireclay powder.

Technological process of furnace lining

The laying of a protective casing around a metal plate is carried out:

  • red solid brick, which has a high degree of heat resistance and a long service life;
  • fireclay brick, which has the same characteristics, but a higher cost;

  • ceramic refractory brick: it has all the positive properties of solid brick, but at the same time it has a more aesthetic appearance and can be used as a cladding brick.

In some cases, masonry is carried out with hollow bricks, but it must be taken into account that it has worse heat retention characteristics.

It is advisable to soak the brick before starting work. Dry brick is able to quickly absorb the liquid fraction through capillaries and does not allow the binding part of the solution to penetrate inside to increase the adhesion of the masonry. In the summer, this method is not difficult.

If the construction process takes place in the autumn-spring period, in cold, damp weather it is quite problematic to dry wet bricks into the finished product. Heating for drying means dealing a blow to the strength even before the stove starts operating: uneven heating will destroy the seams. It is also impossible to leave the stove undried over the winter; the cold will tear the masonry under the influence of negative temperatures. In this case, make a more liquid solution and slightly wet the surface of the brick.

If there is insufficient construction experience, for the convenience of maintaining a horizontal plane, stretch a cord or fishing line around the perimeter of the masonry. The inconvenience of this method is the need to raise the fishing line with each row.

You can pay 30-50% less for light, depending on what electrical appliances you use.

Finishing a stove in a bathhouse - how and with what material to finish a stove in a bathhouse


Finishing a stove in a bathhouse In this article, you will learn about finishing the stove: the material for lining the stove depends not only on the preferences of the bathhouse owner, but also on some other factors.
