How to properly insulate a steam room in a brick bath. Do-it-yourself warming of a steam room in a brick bath Warming of a block brick bath inside

A brick bath outperforms a wooden one in that the walls do not require special waterproofing and fire protection. The brick is absolutely not afraid of fire, and it absorbs little moisture. But he has weakness"- high thermal conductivity, which prevents bath rooms from quickly warming up and retaining heat as much as possible. Insulation of a brick bath helps to increase the thermal insulation properties of the steam room and other rooms. Without it, the heating time of the building increases by about 3 times, and the cooling rate is high. Consider how to insulate a brick bath and all of it structural elements using safe materials.

A private bath is used periodically, so it makes no sense to maintain a constant positive temperature inside it. True, a cold brick will freeze through in winter, and if you start heating, then most of the heat will be spent on heating it. And what is the point of heating the stone? If the walls are insulated from the outside, then the entire brick will be inside the pie, covered only by the clapboard. And you have to spend money on heating it, whether you like it or not.

With internal insulation, the brick box will remain outside the cake, and a layer of insulation will insulate it. In this case, your expenses for heating the premises will decrease, because the insulation will not let hot air out and, with proper installation, will give most of it back into the premises.

Internal insulation of the walls of the bath

Consider options for how to insulate a brick bath from the inside.

Option 1. Create a second wall

Most often, second walls are erected inside a brick box. The material is a bar-ten, which in itself is a warm material and does not emit harmful components when heated.

Mount the cake as follows:

• A crate is stuffed onto the brick.
• A waterproofing film is fixed along the crate.
• Install timber walls.
• A second crate is stuffed over them.
• Close the beam with fiberglass, fixing it to the crate with a stapler. Between the bars of the crate, the fiberglass is not stretched, but an overlap is made, so that later it is easy to place a heater.
• Insulation plates are inserted into the spans between the crate.
• To protect the heat insulator from internal steam, it is covered with foil or vapor barrier film on top.
• The lining is stuffed last.

The foil is attached to the crate with a construction stapler, without pulling it close

Regardless of the type of insulation, its thickness must be at least 10 cm. harmful substances. For this, basalt or fiberglass heaters are optimally suited, which are not afraid of moisture. If there is a desire to close the timber with polystyrene foam materials, then it is better to choose penoplex. It has a higher resistance to high temperatures than foam, and in the event of a fire, this insulation tends to self-extinguish. But still do not do the warming of the steam room in a brick bath with polystyrenes. With strong heating (over 100 degrees), they will begin to char and release toxins. For the steam room, it is worth taking only basalt materials.

Option 2. Double layer of insulation

Considering options for how to insulate a brick bath, you can focus on creating a double layer of insulation. Its difference from the 1st is that instead of timber walls an additional 10-centimeter insulation is laid in the crate.

The wall cake will look like this:

• Brick.
• Waterproofing.
• Crate.
• Insulation.
• Waterproofing.
• Second crate.
• Fiberglass.
• Insulation.
• Vapor barrier.
• Clapboard.

The thickness of the internal insulation pie will be about 22 cm.

When choosing a heater, line the first layer (closer to the brick) with extruded polystyrene foam. He is not afraid of moisture, so external vapors that have got through the brick are not dangerous for him. Choose the second, inner layer of insulation, taking into account the room in which you will lay. In all rooms, except for the steam room, it is worth covering it with foil foam. This foam material is covered on one side with a thin layer of foil, which will simultaneously reflect IR rays and become a barrier to internal vapors.

For a steam room, it is better to choose a basalt insulation, and close it with a special foil for baths on top. So you will avoid the release of harmful substances during strong heating of the room. Joints in foil insulation and foil are sealed with special aluminum tape.

Foundation insulation

A powerful conductor of cold in the bath is the foundation, because concrete materials are selected for it, which are not characterized by thermal insulation characteristics. Even before the erection of brick walls, the upper part of the foundation is waterproofed with roofing felt or roofing paper in order to prevent moisture from the soil from entering the brick. But this is not enough. It is necessary to carry out external insulation of the entire surface of the walls of the base in order to increase the level of heat saving of the floors and to exclude movements and shrinkage of the foundation. On Russian lands, many soils are heaving, i.e. in winter, when freezing, they expand their volume. As a result, the pressure on the foundation increases, and this leads to distortions and cracks in the foundation. If you lay a layer of insulation between the soil and the walls, it will soften the pressure and make the structure stable.

For insulation, it is better to choose from two options for insulation: foam or sprayed polyurethane foam. In fact, both materials have approximately equal specifications:

• not afraid of ground movements;
• have increased compressive strength;
• waterproof;
• high quality thermal insulators.

You will have to choose based on your construction skills and the state of finances. So, spraying with polyurethane foam will cost significantly more than foam plastic, but craftsmen will do it for you in a day. At the same time, the main advantage of such a heater will be a continuous, durable coating in which there are no joints. Those. moisture and frost will not be able to find loopholes to penetrate deep into the foundation slab.

Penoplex is produced in plates, and they are fixed to the walls of the foundation with special mastic or adhesive. Any owner who has an idea about construction will cope with this. But for the day to mount the insulation will not work. This is a slow process, because the plates must be tightly joined, all seams must be sealed, and the corners must be blown out mounting foam.

Floor insulation

The floors in the bath have to withstand both high humidity and the temperature difference between the ground and the premises. Therefore, before the installation of concrete floor slabs, the entire subfloor should be covered with expanded clay or slag. Moreover, the layer of the insulating pillow is calculated based on the thickness of the walls. If the walls are 20 cm, then the expanded clay should be 40 cm. The underground is not used in the baths, so fill everything with insulation inner space foundation. This will provide additional dryness to concrete or logs.

How to insulate a concrete floor

• If the floors are concrete, then the insulation of the brick bath from the inside begins with the waterproofing of the floor slabs. They are coated with water-repellent mastics (for example, rubber), and a rolled waterproofing agent is laid on top - roofing material or a special film.
• Foam or foam plastic is laid on top of the waterproofing.
• From above it is reinforced with a metal mesh and poured with a layer of concrete.
• The last stage is pasting with floor tiles.

Expanded clay pillow improves the quality of thermal insulation of floors in the bath, regardless of the material of the walls

wood flooring technology

It should be borne in mind that for baths, wooden floors are not too a good option because wood is afraid of high humidity. But if you have conceived just such a floor, then first of all take care of the quality of ventilation in the underground. Without it, the logs and beams will instantly rot.

• The expanded clay pillow, which was mentioned earlier, must also be created in this case.
• Beams and logs treated with antiseptics are laid along the top.
• They are covered with a vapor barrier film.
• Draft floors are laid from edged boards.
• Lay foam.
• Close the insulation waterproofing film.
• Lay wooden finishing floors.

Insulated ceiling: not afraid of heat and steam

If we consider how to insulate a brick bath in a complex way, then we must definitely pay attention to the ceilings. Most of the hot air escapes through them, so a blockade is simply necessary here. But the climate of the bath, especially in the steam room, is characterized by very high temperatures in the upper part of the structure, because both the heat and the vapors, according to the laws of physics, rush to the ceiling. So its design must be resistant to moisture and hot air. We immediately exclude polystyrene foam materials, because in such heat they will harm human health.

If you study the insulation of a brick bath from the inside on the video, then most experts recommend insulating the ceiling with mineral wool, but with mandatory double-sided waterproofing. Also a good option is to lay fiberglass on the ceiling, two clay-sand layers (one with sawdust, the second with vermiculite) and on top of all this - foam. But again, for a steam room it is better to take not polystyrene foam, but foil-coated fiberglass.

Fiberglass is laid with foil inside the steam room so that it beats off the maximum amount of heat and steam

With proper insulation of a brick bath, you will significantly speed up its heating and reduce the cost of maintaining the desired temperature while soaring.

Exit exhausted from the steam room in your own bathhouse and ... freeze ... It is unlikely that such a gloomy prospect attracts anyone. To prevent this nightmare from becoming a reality, you need to take care of the quality insulation of the bath. Let's talk about how to insulate a brick bath.

Of course, the brick itself is a rather warm material, but the task of the owner of the bath is to achieve rapid heating of the room and a long time to retain heat, because all these are factors for economical and comfortable operation of the bath. Simply put, high-quality insulation of a brick bath will make your stay more enjoyable and cheaper.

Requirements for thermal insulation of a brick bath

The building itself has a different purpose than a residential building, therefore the requirements for its thermal insulation are noticeably different. It is necessary to achieve not only heat, but also hydro and vapor barrier. To do this, insulation begins with the foundation. It is laid with mineral mats.

Prior to the start of the arrangement of the floor, the soil under it is also carefully insulated: expanded clay or slag is poured. The thickness of the material layer should be one and a half to two times greater than the thickness of the walls of the bath. You can lay the floor only on dry beams and logs.

Wall insulation work

From the inside, the bath is finished and at the same time insulated with wood paneling. However, before the start finishing works vapor barrier is made. As a vapor barrier material, foil and kraft paper have proven themselves well.

The walls in the steam room and washing room require special care - it is better to use foil, and for the rest room you can get by with kraft paper. The material is laid between outer wall and internal wooden paneling. It is important to insulate the ceiling as well, otherwise the efforts aimed at insulating the walls will give a very mediocre result.

Ceiling in the area of ​​special attention

A layer of fiberglass is placed on top of the ceiling. The next layer is poured on top of the laid material. It consists of a clay-sand mortar with sawdust or chopped straw (chaff). The composition is mixed in a ratio of 1:1. The optimal thickness of the solution layer on fiberglass is 20-30 cm. The next layer is a clay-sand mortar with vermiculite (1: 3, respectively). Its thickness should be about 50 mm.

In order for the insulation to be of high quality, you need to let the solution dry well. It usually takes a couple of weeks to two months. This difference in terms is due to the peculiarities of weather conditions. After the solution has dried, a foam plastic 100-150 mm thick is placed on top, after which the entire structure is poured cement mortar With foam plastic(1:3 respectively). If in the project there is an attic room above the bath, then all layers of thermal insulation are covered with roofing material or roofing felt, on top of which a wooden floor is laid.

From the inside, the ceiling is insulated as follows: under the rough board, laths of the crate are fastened with a step of 500 mm, between which a layer of fiberglass is fixed, after which - thermal insulation (about 50 mm). As a heater, basalt or kaolin wool is usually used. The next layer is foil fabric or foil. When all layers of insulation are installed, you can finally sheathe the ceiling with eurolining. The surface is securely insulated.

What can you save on?

How not to insulate the room, and if the windows are not airtight, the effect will be zero, since most of the heat leaves through the window profile. The large field of window glazing also contributes to the rapid cooling of the room.

Loosely inserted glass is a factor in the appearance of cracks that allow cold air to pass through, and even provoke the appearance of drafts. In general, high-quality insulation of a brick bath is possible only with a competent approach to the choice of windows, their correct installation and sealing.

All holes and slots must be carefully caulked, and the frames must be fitted as tightly as possible to the bindings. By the way, this measure will perfectly prevent possible fogging of windows in the future. Glass must be carefully sized. They need to be well fixed. Single glazed windows are unacceptable for baths. You need at least a double, and even a triple is better. Perfect option- double-glazed windows.

Insulation of a brick bath is impossible without sealing windows. They are sealed and sealed with putty. The nails fixing the glass are also covered with putty. You can install glass blocks. Windows serve not only to illuminate the room, but also for ventilation, so do not forget about the window. Learn more about bathroom windows.

Some nuances

1. You can reduce heat loss by placing windows as low as possible, installing low doors to the steam room and raising the threshold in it.
2. If there is no plumbing in the bath with hot water, and the water is heated in a container installed directly in the bath, then it is also desirable to insulate the tank: so hot water keeps the temperature longer.
3. It is best to fill the heater with granite and basalt. Volcanic rocks are preferable for a sauna stove.
4. The boiler is insulated with foil plates. This provides good thermal insulation and a high degree of fire safety.

When it comes to keeping the heat in the bath, there are no trifles. By following our recommendations, you will ensure a light steam and a great rest. Good luck!

Insulation of a brick bath from the inside will not solve all issues of heat preservation. This complex work, which involves the insulation of all planes.

After all, heat leaves the room in large volumes through the ceiling, and it also perfectly draws cold through the floor. Therefore, today we will consider the question of how to insulate a brick bath in the most optimal and high-quality manner.

Also on the video in this article you can see the whole process of doing the work and understand what and how to do it.

We carry out warming

How to insulate a brick bath, now consider in more detail. Everything in this matter can be done with your own hands and without outside help.

Then the price of the work will be much lower, and there will be no need to worry about the quality. Below is a guide to how to do this job.

Milestones

Insulation of a brick bath from the inside and outside is done according to a certain scheme and has already been worked out and tested by time. First of all, it is necessary to minimize the heat losses of the bath room.

So:

• Particular attention should be paid to warming the steam room, the air temperature in which depends only on your personal preferences. The average temperature in this room varies from 60 to 130 degrees. As for the Russian bath, in which heat is “caught up” by hot steam at a high level of humidity in the bathhouse, here you can limit yourself to a temperature of 60-90 degrees.
• In the bathhouse, it is necessary to keep the temperature as high as possible for as long as possible. Maintaining the right temperature in conditions of high heat losses will require you to have a huge amount of fuel and energy, which can ruin your vacation.
• Moreover, due to heat losses, there is a significant reduction in the life of the bath itself. Excessively long stay in conditions of high humidity can provoke premature decay of wooden elements. This also leads to a decrease in the service life of the heaters, and individual models of stoves are not able to fully function in such baths.
• The reduction in service life also applies to brick ovens. This is due to the imbalance that occurs due to the large difference between heat transfer and heat loss in the bath room. If the amount of heat that goes outside the bath is significantly greater than the heat output of the stove, then the stove will not be able to cope with heating such a room. The result of this will be the lack of comfortable conditions for healing rest.
• Brick belongs to the category of good thermal insulation materials. But a completely different task is set before the builder and the owner of the bathhouse, which is to ensure the most efficient and fast heating of the bathhouse, as well as to achieve the longest possible preservation of heat in the bathhouse, which allows the most comfortable and economical use of this room.

How and what to make thermal insulation

Insulation of the walls of a brick bath from the inside is done first. This should be done immediately after the completion of the construction of walls, installation of doors and windows.

Every qualified builder should know how to properly insulate a brick bath, because the temperature in the rooms depends on the quality of these works.

Attention: To ensure better heat retention, multi-layer thermal insulation is used. As a rule, as the first layer are used board materials, on which rolled heat-insulating material with a foil coating is laid.

The insulation technology itself does not present any difficulties. The main difficulty lies in the choice quality material. To facilitate the search, you need to know what basic requirements a good insulation must meet.

This:

1. Resistant to sudden temperature changes.
2. Environmental friendliness. To insulate inner part baths made of bricks, only those insulating materials should be used that will not emit substances that are bad for health.

All these requirements are met by such material as mineral basalt wool, with which you can qualitatively insulate wooden, brick and frame buildings.

Attention: The only significant disadvantage of cotton wool is its increased ability to absorb moisture. Expanded clay or wood shavings can be used to insulate the floor and ceiling.

External thermal insulation can be made using foam, which has many undeniable advantages, including:

1. Simplicity and convenience of operation.
2. High thermal insulation properties.
3. Excellent plate geometry.
4. Excellent soundproofing ability.

Attention: However, it should be borne in mind that the foam can be used exclusively for external insulation of brick buildings. For internal works it is recommended to choose mineral wool boards.

Wall insulation from the inside

Insulation of a brick bath is carried out during the laying process. Brick walls perfectly absorb moisture, so they should not come into contact with the ground. For this, the base is treated with special mastic or roofing material.

The process of thermal insulation of the walls of the bath is practically no different from the insulation of other rooms. But there are still certain features.

So:

• Before proceeding with the thermal insulation of the walls, you need to insulate plastic windows. With the help of polyurethane foam, it is necessary to eliminate all the gaps formed between the window and the wall.
• Hangers and metal profiles have good heat-conducting properties, so they cannot be used for insulation.
• Fastening insulation to brickwork is carried out in two ways: using special glue or dowel umbrellas.
• Also, if the wall is uneven, then you have to make a crate. To check this, we simply take the fishing line and pull it along the diagonals of the plane. If the difference is large, then you need to put a crate.
• The transverse crate is made according to the width of the insulation, but the distance should not exceed one meter.
• A vapor barrier material is laid on the main layer of insulation, which can be used as foil paper.

How to perform high-quality floor insulation

The initial stage of the thermal insulation of the bath should be the insulation of the floor. It should be understood that the floor in the bath can be either solid or with well-thought-out ventilation.

The process of warming a solid floor in a brick bath consists of several important steps.

• First of all, it is necessary to treat the base with antiseptic agents.
• After that, a layer of insulation is laid on the treated surface.
• A waterproofing material is laid on top of the insulation.
• At the end, the floor is equipped with 40 mm grooved boards.

If a brick building has a ventilated base, then the stages undergo slight changes.

• First, the base is covered with a layer of sand.
• Styrofoam slabs are laid on top of the sand layer.
• Then a mixture is laid, consisting of cement, sand and foam chips.
• The next layer will be a mixture of vermiculite, cement and sand.
• A rolled roofing material is laid on top of these layers.
• At the next stage, the reinforcing construction mesh is laid.
• All this is poured with a solution of crushed stone and concrete.
• Finally, a ventilated wooden floor is installed.

How to properly insulate a ceiling

Warm air rushes up, so the insulation of the ceiling should be given increased attention. For high-quality and dense insulation, it is necessary to choose a reliable insulation.

For greater reliability, it is advisable to put a vapor barrier foil on the side of the steam room. To eliminate the smallest holes, it is advisable to carefully glue it with aluminum tape. Styrofoam plates are laid on top of the foil, the joints between which are treated with mounting foam.

• There should be no baths in the room big windows and tall doors.
• In order for the boiler installed in the bath to keep the desired water temperature longer, it must be insulated with foil plates.
• In order to carry out high-quality thermal insulation of a steam bath made of bricks, you should choose only natural materials.
• The gaps formed between the plates are sealed with mounting foam.
• It is advisable to perform thermal insulation of a brick bath during the construction of a building.

How to carry out external thermal insulation of walls

Now we need to insulate the brick bath from the outside. For external thermal insulation work, the same non-combustible mineral wool insulation is used, which perfectly retains heat and has good soundproofing properties.

When using rolled insulation, it must be well fixed on the outer walls of the building. This can be done using wooden planks or slats.

Attention: With external insulation, special attention should be paid to the connection of the insulation. Indeed, during deformation, it loses its properties and this should be given special attention.

If as thermal insulation material mineral wool mats are used, then you need to follow a slightly different sequence of work:

• First, a crate made of corners and a metal profile is fixed on the outer surface of the walls;
• Each cell of the crate is filled with heat-insulating material;
• The joints formed between the mats are glued with construction tape;
• The entire structure is covered with a layer of waterproofing.

At the final stage, the walls are sheathed with any finishing material.

To insulate a brick bath, you can use foam sheets. In this case, before starting work brickwork cleansed of all contaminants.

• All flaws present there are removed from the surface of the wall, such as deep seams and chipped bricks.
• Styrofoam sheets are glued to the plastered wall using a special adhesive.
• After the glue has completely dried, the sheets are fixed with dowels. At five points of each sheet of foam, special dowels with wide caps are screwed.
• The joints formed between the sheets of heat-insulating material must be carefully coated with glue.
• A reinforcing mesh is laid and fixed on top of the foam. The resulting surface is treated twice with plaster.

How to insulate a brick bath, you now know. Give preference when buying materials to trusted brands. Do not buy cheap Chinese products. It often emits a harmful odor when heated.

It is too early to rest and dream about a steam room with a broom, because it is necessary to insulate the structure. Brick walls have high thermal conductivity - this means that it will take a long time to heat the stove, and the temperature will drop quickly. To keep the heat as much as possible, you need to figure out how to insulate a brick bath from the inside.

Why is internal insulation necessary?

A bath is a room that is not used daily, therefore, during the cold period, its brick walls freeze through, and a lot of heat is spent on warming them up. Exterior finish will not be able to significantly affect this situation, and the placement of a heater inside will make it possible to accumulate the temperature in the room and not waste additional resources.

The choice of insulation

For effective insulation from the inside, it is necessary to lay a layer of material with a thickness of at least 10 cm. The temperature in the bath rises to high levels, therefore, materials that do not contain toxic components that actively evaporate into the air when heated are selected for thermal insulation. Insulation should not support combustion, so as not to cause a fire. Another important requirement is resistance to moisture, because the bath is constantly damp. Considering all of the above factors, the following are recommended as a heater for brick walls and a bath ceiling:

• basalt wool;
• Styrofoam;
• expanded clay for floor and ceiling;
• foil foam.

Floor insulation

The basis of the bath is a concrete foundation, through which the cold freely penetrates. strip foundation from the inside will significantly reduce heat loss. Best way freezing control - thermal insulation with foam plastic, produced in the form of plates. It is not afraid of moisture and negative temperatures, so it will last for decades. It is quite easy to install the material. The insulation sticks tightly to concrete surface using mastic or an adhesive mixture, the joints of the panels are glued with a sealant, and the corners are blown with foam. This layer will prevent the cold from penetrating into the concrete foundation.

Note! Expanded clay will become an inexpensive and reliable material for insulation and waterproofing. The space under the floor is covered with a layer of granules that is 1.5–2 times the thickness of the walls. Sand is poured under the expanded clay with a layer of up to 20 cm.

Insulation of the concrete floor begins with the implementation of waterproofing. Most often, it is coated with liquid rubber mastic or covered with roofing material. From above, thermal insulation is carried out with foam, which allows steam to pass through and is resistant to temperature changes. The next step: fixing the reinforcing mesh and pouring a monolithic screed. After it dries, the floor covering is laid.

Expanded clay - suitable option for wooden floor insulation. Beams and logs treated with an antiseptic are laid on it. Top fit vapor barrier film, and rough floors are laid. On the edged board the foam is tightly laid and covered with a waterproofing sheet. The final stage is the finishing floor.

Ways to insulate the walls of the bath

You can keep the heat inside the bath by making an additional wall of timber or by laying a thick layer of insulation. For the construction of a wooden partition, you will need a beam treated with a special compound that protects against moisture. Process technology:

1. On the brick wall the crate is fixed.
2. Using a stapler, a waterproofing film is fixed.
3. A wall is mounted from a bar 10 × 10 cm, the lumber is fastened with self-tapping screws.
4. The second tier of the crate is stuffed.
5. A roll of fiberglass is fixed on the racks with brackets. The material does not stretch, it is fixed with sagging.
6. Insulation is placed between the guides under the fiberglass. As insulation, mineral wool or foam can be used. The latter option is suitable for all rooms, except for the steam room.
7. A foil is fixed, which serves as a reflector of heat and wet steam.
8. The finishing lining of the walls with clapboard is in progress.

The second option involves replacing an additional wooden wall with a layer of insulation. The sequence of work will be as follows:

• A waterproofing film is fixed on a brick wall.
• A wooden beam 5 × 5 cm, treated with an antiseptic, is stuffed vertically. The distance between the racks is chosen 1 cm less than the width of the insulation, which will allow you to tightly lay the material and not create cold bridges.
• Insulation is laid with a thickness of at least 10 cm.
• A sheet of waterproofing is attached on top of the material.
• The second layer of the crate is stuffed from a bar, similar to that used earlier.
• Fiberglass is freely attached to the racks.
• Insulation plates are tightly inserted into the gaps between the crate beam and covered with fiberglass.
• Next, a layer of material that reflects thermal radiation is fixed with a stapler. For a steam room, only basalt wool is suitable as a heater, the insulating layer is made of aluminum foil, which does not emit harmful components when heated. In other rooms, penofol can be used for insulation and waterproofing, which reflects up to 90% of radiation and is designed for temperatures up to 100ºC. The foil material is glued at the joints with aluminum tape.
• Performed . The boards are fixed at a distance of 1–1.5 cm from the aluminum layer. This air gap is necessary for ventilation and separation of wood and aluminum foil, heated to a high temperature.

The internal wall cladding is made of lining of various types of wood. For a steam room with high temperature and humidity, linden, cedar, and larch are used. They have low thermal conductivity and high resistance to moisture. The rest room is sheathed with pine boards, the wood has a pleasant appearance, and when heated, it spreads healing substances.

Note! High humidity conditions take their toll on metal fasteners, causing rapid corrosion. In order for the screws to last a long time, choose fasteners with galvanization.

The total layer of the insulation structure should be about 22 cm, then it will serve effective thermal insulation. Several types of insulation can be used in the pie, closer to the brick walls, where moisture can penetrate, it is more correct to lay polystyrene foam boards.

ceiling insulation technology

Hot air rises to the ceiling, so it’s worth figuring out how to properly insulate it. A popular material for do-it-yourself thermal insulation work is basalt wool, which is resistant to high temperature and environmental safety. Styrofoam is also suitable for this purpose, it is easy to cut and has low thermal conductivity. To reflect infrared heat rays, you will need foil or a material with a reflective layer. In some cases, improvised means are used for insulation - clay and straw or sawdust. They are mixed in a ratio of 2 to 3, moistened and laid on a crate in 30 cm increments or on fiberglass. After drying, thermal insulation with a layer of foil is laid on the clay base, and sheets of plywood are stuffed on top.

Note! When working with mineral wool, it is important to perform high-quality waterproofing. The first layer will be foil, spread out with an overlap of 3-4 cm and glued at the joints with metallized tape. Then the insulation is tightly laid and covered with a vapor barrier film on top.

You can replace cotton wool with foam, but only lay mineral material over the steam room. You can cover the warming cake with boards or plywood. Interior decoration the ceiling is made of the same material as the walls.

Properly executed insulation of a bath with brick walls will save fuel and enjoy hot steam.

Watch an informative video about the insulation of the walls of the bath:

To figure out how to insulate a brick bath from the inside, you need to understand the performance characteristics of the wall material. Compared to a wooden sauna, a brick building has the advantage that neither fire protection nor waterproofing is required. has only such a drawback as a small thermal conductivity. This prevents the room of the bath or sauna from warming up well, and the heat is not completely retained. To increase the thermal insulation properties of the building, you can carry out.

In order for the bath to be warm, it must be built in one and a half or two bricks.

Which insulation will be better - external or internal?

If we are talking about a private bath, it does not make sense to maintain a constant temperature above zero from the inside all the time. But due to periodic use in the cold season, the walls can freeze through, and when trying to flood the bathhouse, all the heat goes mainly to heat the stone. When performing insulation from the outside, the brick almost does not heat up, only the lining covers it, so much more resources will be spent on heating than it could.

Thermal insulation of the bath walls from the inside helps to reduce fuel costs. When properly installed, the heat-insulating material does not release heated air outside, and it is stored inside the room.

Building an additional wall

You can insulate a brick bath from the inside by building an additional wall. As a material for this, a bar is used, which, according to its characteristics, is quite heat-saving and does not emit components hazardous to health.

Installation of a warming cake for the walls of the bath is carried out according to the following scheme:

1. A crate is laid on the bricks.
2. Waterproofing is attached to the installed frame.
3. Raising a timber wall.
4. Another crate is stuffed on top.
5. The beam is covered with fiberglass, which is fixed to the crate with a stapler. Fiberglass should not be stretched between the crates. An overlap is made, which subsequently makes it easy to place a heater.
6. Tiled insulation is inserted into the gaps between the crate.
7. In order to create a barrier for internal steam, the insulating material is covered on top with foil or film vapor barrier.
8. Lastly, the lining is hammered.

Regardless of which insulation material is chosen, its thickness should not be less than ten centimeters. It is only necessary to pay attention to whether the insulation emits toxic substances when heated.

Fiberglass or basalt materials that are not exposed to moisture are considered optimal. It can be, for example, penoplex - with elevated temperatures it performs better than polystyrene, and also has self-extinguishing properties. But it is necessary to be more careful when using polystyrenes to insulate a brick bath - with strong heating, they can char, which leads to the release of harmful substances. It is better to use basalt materials in the bath room.

Insulation in two layers

When considering insulation options, it can sometimes the best way out turn out to be the creation of a double insulating layer, that is, instead of beams, an additional insulation 10 cm thick is laid in the crate.

The design of the wall insulation pie will look like this:

• waterproofing layer;
• crate;
• warming material;
• waterproofing layer;
• one more crate;
• fiberglass;
• warming material;
• vapor barrier layer;
• lining.

The total thickness of the insulating cake is approximately 22 cm. It is better to line the layer of heat-insulating material that is closer to the brick wall with extruded polystyrene foam. This material is not afraid of moisture and will not absorb external vapors. The inner layer of insulation must be selected taking into account the characteristics of the building being repaired. All bath rooms, with the exception of the steam room, should be covered with foam plastic - foam material with a foil layer, which will become an obstacle to water vapor.

For the steam room choose better materials from basalt, and cover with special foil for a bath on top. So with strong heating of the air, toxic substances will be released a little less. Seal the joints of the material with aluminum tape.

Why insulate the foundation of a brick bath

It is also necessary to perform thermal insulation of the bath floor. But measures to insulate bath floors lose their meaning if the foundation is not protected from the outside. In the bath, the floors are affected and high humidity and the difference in room and ground temperatures. Therefore, before the ceilings are mounted, the underground should be covered with slag or expanded clay. There is no underground in the baths, so the interior space of the foundation must be filled with insulation.

In a structure such as a bath, the foundation can become a powerful conductor for cold air - it is made of materials that do not have heat-saving characteristics.

When building a bath, the top of the foundation is waterproofed with roofing felt or roofing material to protect the brick from moisture from the soil. But this is rarely enough. It may be necessary to carry out insulation from the outside for all walls of the foundation. This helps to increase the degree of heat saving of bath floors and prevent shrinkage and movement of the foundation.

When choosing a material, you must first of all be guided by your construction capabilities and the state of your wallet. It is advisable to draw up work plans before starting the insulating materials. For example, choosing polyurethane foam will cost more financially than penoplex, since insulation is applied using special equipment. But the installation will be carried out in just a few hours, the coating is very durable, without joints. There are no loopholes left for the penetration of cold into the foundation.

Such material as penoplex is produced in the form of plates. They are glued to the foundation walls with an adhesive mixture or special mastic. Any owner of his own bath is able to do this work on his own. But this type of insulation installation will take much longer - the plates must be well joined, the seams must be well sealed, and some - for example, in the corners - should be blown out with mounting foam.
