Insulating a bathhouse from the inside: cheap and safe. Which insulation is best for a bath? Which insulation is best for a steam bath

One of the most important stages construction of a bathhouse means insulating a steam room, since only a stable temperature regime in this room will allow you to achieve excellent performance characteristics, as well as a comfortable and beneficial microclimate. Later in the article we will talk about this procedure.

The danger of improperly insulating the steam room

Any errors during insulation work can lead to low quality accepted bathing procedures and deterioration of the general operational characteristics of the premises. Intense leakage of steam and thermal energy can lead to deformation finishing materials, to the formation of fungi and mold on them, etc.

In this regard, it is possible to formulate a set of rules that should be followed when insulating the steam compartment of a bathhouse:

• thermal insulation must be of high quality in everything: correct installation, reliability of materials, etc.;
• the tightness of the ceilings is very important, since the effectiveness of the procedures depends on the degree of steam retention in the room;
• In no case should you save on the purchase of thermal insulation materials, since this can lead to their rapid deformation and deterioration of the overall visual condition of the steam room in the photo or during visual inspection.

Optimal building materials for insulating a steam room

If we're talking about about how to insulate a steam room from the inside, you should immediately point out the main qualities that the selected materials should have:

• environmentally friendly without emitting any harmful substances human body substances;
• high degree fire safety, necessary for rooms where extreme temperatures are reached;
• moisture resistance, which allows you not to be afraid that the material will get wet and become unusable after the first bath procedure.

Most of all, basalt-based materials meet all the stated requirements. We are talking about stone and mineral wool. The vapor barrier layer in the ceilings can be created from aluminum foil.

Start laying steam and hydro insulating materials, as well as the insulation itself for the steam room, is possible only after all the wooden elements of the floors have been processed using antiseptics. It is always worth remembering that floors contain more than one layer of material and thermal insulation is not the crown of the entire structure. Essentially, walls and floors are sandwiches in which each layer is responsible for specific functions.

Competent design of a bathhouse is the key to success

In addition to insulating the steam room in wooden bath, it is necessary to create a competent design of the entire structure.

When developing a project, it is necessary to take the following parameters as a basis:

1. First, you need to decide on the size of the bath. To do this, the maximum capacity of visitors and the number of rooms that are planned to be equipped inside the building are taken into account.
2. The project itself is created with an emphasis on taking into account all possible losses of thermal energy and minimizing them. For example, the locker room is located at the exit from the bathhouse in order to minimize the access of cold air masses to the main part of the building where the steam room is located.
3. A vestibule should be installed between the washing room and the steam room, which will not allow steam to flow into a room with a lower temperature.
4. The door in the steam room should not be large, but its junction with the floor should be raised using a special threshold, which does not allow cold air to enter the room.
5. The greatest convenience of the steam room is achieved when the room has a square shape. One of its corners is allocated for installation heating stove. It is advisable that this be the corner closest to the front door.

Also, do not forget that when designing you need to decide on the materials used. If we are talking about how to insulate a steam room in a bathhouse, then artificial or natural materials can be used.

Natural materials are the following types:

• tow – used to seal cracks that form when creating log house or buildings made of wooden beams;
• sphagnum - laid between the crowns;
• building moss is a standard wall insulation.

If the steam room in the bathhouse is insulated artificial materials, then we are talking about the following varieties:

• extruded polystyrene foam;
• mats made of stone or mineral wool.

Each of these materials has a long service life, high level mechanical stability, moisture resistance, etc.

The importance of insulating ceilings in a steam room

It falls on the ceiling large quantity insulation material compared to wall ceilings. The reason for this is air convection: when heated, it rises to the ceiling, and cold air falls in its place. The same thing happens with water vapor. In this regard, thermal insulation materials are laid in the ceilings in two layers, which will reduce the level of thermal energy losses.

The ceiling thermal insulation of the steam room of the bath is carried out in stages:

1. The rough surface of the ceiling is covered with paper rolls. The sheets are overlapped with each other with sufficient spacing. The sheets are fixed using wood blocks measuring 5x5 centimeters.
2. The empty spaces between the beams are laid with heat-insulating material.
3. All ceiling segments are then covered with aluminum foil, which is secured with adhesive tape. It is important to avoid the formation of gaps and cracks in this layer. It is the foil surface that maximizes the preservation of water vapor in the steam room and prevents condensation from forming. In the absence of aluminum foil, the insulation of the steam room ceiling can be done with paper or cardboard impregnated with special compounds. It is worth finding out in advance what is the best way to insulate the ceiling in a bathhouse in your case.
4. On top, the covering is once again lined with bars measuring 2x3 centimeters. This allows for improved floor ventilation.
5. The selected facing material is mounted on top of these bars.

Features of insulating steam room walls

After the ceiling in the steam room has been insulated, you can begin to process the walls. The rough surface must be specially prepared for this procedure. Any joints, cracks and other cavities must be plastered or sealed with sealant.

1. First, the aluminum foil is fixed using wooden blocks measuring 4x4 centimeters, placed horizontally.
2. Thermal insulation material is laid between the beams.
3. Then the foil is finally fixed with a construction stapler. It is important to stretch the material, but at the same time avoid the formation of gaps, cracks or tears in the foil.
4. All joints of the structure are glued with a special aluminum tape.
5. On top of the tape, bars are attached longitudinally for laying the selected facing material.
6. The work is completed by laying the finishing coating.

When finishing, low-density materials should be used, since insulating a steam room in a bathhouse requires everyone to structural elements The main thing is to preserve heat in the room. It is best to pay attention to materials made from pine, linden or aspen wood with thin planks. They will not only reliably protect the steam room from heat loss, but will also look aesthetically pleasing in photos and during visual inspection.

Installation of the material should be carried out horizontally to reduce the total load distributed across the main structural elements. The insulation material should be penofol, which is gaining popularity in the construction market.

How to insulate a concrete floor in a steam room

In the end, you should move on to insulating the floors in the steam room. In addition to thermal insulation, you should also take care of waterproofing the floors. There are two types of material installation algorithm. In this paragraph we will talk about floor insulation in a steam room with a concrete base.

The following algorithm for thermal and waterproofing is simplified, since it is used when laying under tiles.

The work is performed as follows:

1. The base is leveled to a perfectly level state.
2. Apply on top of it bitumen mastic and wait for it to dry completely.
3. Then roofing felt and polymer film are laid.
4. Top mounted tile(read: " ").

More quality construction for thermal insulation of concrete floors:

1. A plywood sheet is mounted on the rough base.
2. Waterproofing with a spade on the walls is laid on it.
3. Aluminum tape All joints are taped.
4. The gaps are sealed and insulated with a construction hair dryer.
5. A reinforcing mesh is laid on the layer and filled with a layer of concrete mortar.
6. After the screed has hardened, you can begin laying the tiles.

When pouring concrete screed it is important to consider the age of the wood used to create chopped bath. It is important to use material that is at least 2 years old. Otherwise, shrinkage of the structure will occur, which will cause deformation or destruction of the foundation.

Working with a wooden base

The work is performed as follows:

1. Mineral wool is placed under the logs.
2. Rolled roofing felt is laid on it.
3. All wooden elements in the ceiling structure are treated with special antiseptic agents.
4. The subfloor is laid on roofing felt.
5. The work is completed by finishing the surface with a finishing floor covering.

After the insulation for the steam room is laid from the inside into the floor covering, the floor “pie” looks like this:

• foundation;
• wooden beams;
• vapor barrier material;
• lining and thermal insulation material;
• floor board.

Also, during the process of laying floors, care must be taken to create a high threshold under front door. This is the most important functional measure aimed at protecting the steam room from cold air masses entering it. Naturally, complete preservation of water vapor indoors can only be ensured if door leaf fits as tightly as possible to the frame and threshold.

We must not forget that a separate area in the room must be allocated for the installation of the stove and the subsequent removal of the chimney. A separate foundation base with a height greater than that of the main foundation is mounted under the furnace.

When equipping walls and ceilings, you need to take into account that a chimney will exit through one of the ceilings, for which you will have to cut square hole and equip it with a frame. The rules require that the chimney from the stove be located at a distance of at least 20 centimeters from any wooden elements in the structure of the bathhouse. This hole is closed with a stainless steel sheet.

Bottom line

The article describes in detail the procedure for insulating walls, floors and ceilings in steam bath compartments. It is important to take into account all the recommendations and advice given in the article, as well as Special attention pay attention to standards for conducting construction work, since installation errors can lead to an unfavorable outcome.

Also, the work can be entrusted to specialists who will take responsibility for all stages - from procurement necessary materials before installation and commissioning of the bath.

The bathhouse is a rather specific design, in which there are constantly large temperature changes and high humidity. Moreover, all these factors are necessary for the normal functioning of the room, which means that the structure must adequately tolerate them and even help maintain the necessary regime.

That is why novice craftsmen often ask questions about how to insulate a bathhouse from the outside and how to correctly create the desired temperature in all rooms of the building.

Principles of thermal insulation of a structure

First of all, it should be noted that this building has several rooms that are very different in their functions and require a certain approach in manufacturing. At the same time, standard insulation of a bathhouse with foam plastic is carried out from the outside in the same way as any other building ().

External skin

• First, the entire structure must be protected from the cold. This is necessary so that when the building is not in use, dampness does not form in it and it does not freeze in winter. At the same time, you can choose any insulation for a bath, but it must be sewn up to protect it from moisture.
• Last time modern masters began to use special liquid formulations, which are simply applied in several layers to the surface and they provide excellent protection by cold. This solution can be called the most optimal, since it not only reduces work time, but also allows you to get rid of unnecessary costs.

• Some experts insulate baths with felt. This method turned out to be not very practical and in its functionality it is much inferior to new technologies.
• It is worth noting that if the building is made of wood, namely timber or rounded logs, then it is not worth protecting the inside from the cold, so as not to spoil appearance premises. That is why the general insulation of bathhouse walls is done exclusively from the outside. At the same time, similar technical solution will help to correctly distribute the dew point and save the building from condensation.

Advice! If you leave this structure without insulation, as was done in the old days, and at the same time reduce the mode of its use, then the service life of the structure will be greatly reduced.

Foundation

To properly insulate a bathhouse, special attention should be paid to the base.

It should protect well not only from the cold, but also from dampness coming from below.

• If the building is on permanent strip foundation, then for its insulation you can use various materials, but with mandatory waterproofing. Expanded polystyrene, which is additionally covered with a layer of film, is perfect for these purposes.
• Such insulation of the bathhouse foundation will perfectly maintain the temperature and, taking into account the quality of the components included in the material, it will last for quite a long time.
• If the structure is installed on a pile foundation, then thermal insulation is performed during the manufacture of floors. For this, expanded clay is often used, which is pre-treated with bitumen to provide it with protection from moisture.
• It is worth noting that in such cases it is best to make a concrete floor, and install thermal insulation in such a way that there is a layer of waterproofing on both the top and bottom.

Advice! It is best to carry out all work to protect the base immediately after its manufacture. This will make installation much easier.

Steam room

When insulating walls in a bathhouse, the steam room needs to be given special attention.

The fact is that in this room you need to constantly maintain the set temperature in order to reduce the cost of bringing the room to the set mode.

• All work is carried out inside, protecting the walls, and then sewing them up with finishing material.
• It is worth noting that insulating a steam room in a wooden bath can be done from the outside, but such work requires the creation of thick layers. This will further increase labor and material costs.
• It is best to use special thermal protection, which is equipped with a reflective layer. It will prevent you from going outside. infrared radiation, which will not only serve as protection against heat loss, but will help to slightly increase the heating of the room.

• It must be remembered that the insulation of the steam room of the bath is done using special waterproofing, which will not emit harmful substances when heated. Recently on the market building materials appeared whole line special means designed specifically for such premises.

Advice! All work is carried out not only on the walls facing outside, but also interior partition, which separates this room.

Attic

• Typical insulation of a bathhouse attic is practically no different from the work that is carried out in any stationary buildings. In this case, special attention is paid to hydro and steam insulation.
• As protection from the cold in this building, it is better to use polyurethane foam. It is an excellent insulator and is almost completely impervious to moisture. However, such a solution is quite expensive.
• Taking into account all the features of bathhouse attics, the installation instructions advise first laying a film on the surface, and then pouring a layer of expanded clay.

Advice! In order to save on foam installation work, craftsmen recommend not purchasing a special device for applying it, but renting it. Many stores often provide such services for wholesale purchases.

Dressing room, wash room and rest room

These premises do not need additional protection by cold. Typically, the insulation of the dressing room is general protection building, which fully copes with the task. However, the floor in these rooms should be additionally equipped with thermal insulation.

The fact is that people often walk on these surfaces barefoot. Considering this, some experts advise installing the simplest system heating Usually the price is small heating elements not very high, but the level of comfort will increase several times.

Special attention is paid to the rest room. This room should not cause much difficulty, since external protection and copes well with the cold. However, some craftsmen try to make this room as comfortable as possible and therefore they produce with their own hands additional insulation, using for this different kinds materials and method of their installation.

Advice! To save money, professionals do not deal with internal cold protection in these rooms. It is much easier to produce quality.

Conclusion

In the video presented in this article you will find Additional information on this topic. Also, based on the text presented above, we can conclude that it not only has its own characteristics, but also a special choice of material for each room.

It is also worth noting the fact that the insulation of the bath in the steam room is carried out separately from other rooms. It is basic and requires protection from all sides, including the ceiling and walls.

A well-planned set of work on insulating a bathhouse can protect you, as the owner of this “healthy” structure, from problems that can appear both immediately after the start of operation of the bathhouse, and over the course of several years. Insulation for a bath should be selected taking into account climate zone, wall material, affordable budget, and, most importantly, it should not pose a threat to the health of those who like to take a steam bath.

Functionally, thermal insulation works on the principle of a thermos: it retains the heat received from the stove indoors, creating the necessary “atmosphere” for hygienic bath procedures, saving energy resources (fuel) on heating and maintaining the necessary temperature regime, preserving the building structure itself from premature destruction under the influence of moisture and high temperature.

Materials for building a bathhouse

When building a bathhouse in the private sector or on a country site, any of the currently available building materials can be used. Foam concrete blocks, brick, wooden beam, round timber (rounded log), frame structures"in company" with creative thinking designers-architects allow you to create a wide variety of options layout of bath rooms and their design.

IN present time It has become fashionable (if the owner is solvent, of course) to build on his own suburban areas entire bath complexes. In them, in addition to the traditional three sections: steam room, washing room and relaxation room, a shower room, a billiard room, a sauna, a second floor with a bedroom and a billiard room, etc.

Therefore, the process of insulating each individual bath will also be individual. The insulation scheme will be focused on the specific features of the operation of a particular bathhouse room, the material of the walls, the number of floors of the building, its area, the functionality of the second floor, etc.

What kind of thermal insulation should a bathhouse have?

The bathhouse operates in special conditions that are “harmful” for building materials: high humidity, heat. This justifies the list of requirements for the thermal insulation of a bathhouse, the properties of insulation for a bathhouse, and the features of its installation. So, the insulation for a bath should:

Thermal insulation of an entire bathhouse with one insulating material is practically impossible. You will have to use suitable insulation for the bathhouse ceiling, optimal insulation for the walls of the bathhouse from the inside, insulation for the roof of the bathhouse. It is also necessary to select floor insulation for the bathhouse - suddenly you will have a desire to provide your bathhouse with a “warm” floor.

High-quality insulation involves the integrated use of various heat and waterproofing materials in combination with various technologies their use. Some materials are not compatible with each other - this fact also needs to be paid attention to.

To insulate baths,…

For thermal insulation of baths, as already mentioned, a wide variety of materials are used in various states of aggregation. Granular materials (amorphous fills), fiber materials, extrusion substances, liquid insulation that hardens upon contact with air and forms a lightweight polymer coating, kraft paper and polyethylene film.

Metallized bath insulation (aluminum foil) tends to reflect thermal radiation, returning it back inside the insulated room. Wooden elements structures can also be protected special composition or " folk remedies» - sawdust in a clay mixture.

Attention! Insulating materials such as roofing felt or roofing felt are CONTRAINDICATED for use in a bathhouse, since at high temperatures they release substances harmful to human health.

All thermal insulation materials used can be divided by “origin”:

• natural insulation materials;
• artificial origin;
• mineral origin;
• organic insulation.

Natural insulation materials

Since ancient times, bathhouses in Rus' have been insulated with hemp hemp, flax tow, moss, and woolen felt. These materials did not “clog” the bathhouse hermetically due to excellent natural air exchange through them. For this quality, such natural heat-insulating substances are “respected” even now. For example, red moss is used for caulking inter-crown joints - not only does it not rot, but it also “carries” bactericidal substances, which are also present in cuckoo flax and sphagnum moss, which are now added to flax tow.

On the opposite side of the scale from “naturalness” there are some disadvantages of these substances: significant cost, “protracted” insulation work, as well as the possibility of damage by birds, mice or moths.

There is an option for processing such substances chemicals, but the “environmentally friendly” characteristic in this case sounds rather dubious!

Great option Natural insulation for a bath can be flax-jute products - flax-jute fabric. This is an elastic, dense material with an affordable price “characteristic”. The combination of fragile jute with elastic flax fibers made it possible to obtain an affordable, effective natural insulation for wooden walls baths, which can be used both for internal and external insulation of wooden walls.

"Organic" insulation

Organic raw materials for such thermal insulation materials are: waste from the wood processing industry, peat, reeds. They are used to make particle boards, wood fiber boards, as well as peat and reed boards. These slabs are “contraindicated” to be very often in the area elevated temperatures. Therefore, such materials cannot be used in a steam room - they can be used to insulate a relaxation room in a bathhouse or a locker room.

Mineral thermal insulation wool. Briefly about such materials we can say - practical and cheap insulation for a bath. And these are the qualities that determined the leading position of these materials in the “thermal insulation of premises” market. Mineral wool There are different compositions depending on the raw material: basalt, diabasalt, dolomite, slag, etc.

They can be used in virtually any building structure, and can also be “calmly” used as insulation for baths and saunas.

Advantages:

• high thermal insulation characteristics;
• this is a non-flammable insulation for a bathhouse, a fire extinguisher;
• long service life;
• elasticity, that is, the absence of significant deformation during installation and during operation;
• ability to repel water.

For convenience and speed of installation, such insulation materials are supplied in the form of ready-made slabs. Another advantage of mineral thermal insulation materials is their “inedibility” for rodents. One gets the impression that such heat insulators - best insulation for a bath. But let's dig deeper...

If this can be called a disadvantage, then due to the significant specific gravity basalt insulation for a bath or stone, for example, are often used for floor insulation, keeping in mind the need for high-quality waterproofing.

According to its operational and technical characteristics mineral insulation close to glass wool. Although the latter has greater flexibility, which in some cases is convenient during installation.

Polymers in the “bath insulation” family

Thermal insulation materials of synthetic origin provide serious resistance to both moisture and high temperatures, and at the same time have a low specific gravity and are easy to install. Today the following types of insulating “synthetics” are available:

• foam plastics;
• foam plastics;
• honeycomb insulation.

All of them are united, as already mentioned, by low specific gravity, “longevity,” and ease of processing and installation. Recently, antiprenes have begun to be added to these polymers, which turns such heat insulators into non-flammable substances, capable of “extinguishing a random spark, even becoming a fireproof barrier in the path of the flame. Suitable for both indoor and outdoor exterior finishing baths

Attention! For interior decoration Bath foam CANNOT be used, since at high temperatures it can release phenol, which is harmful to human health! Carefully study the documentation on thermal insulation, in particular on the possibility of use in high-temperature rooms.

The sequence of thermal insulation of a bath

Having decided which insulation is best for a bathhouse, let’s deal with further actions. The process of thermal insulation of a bath can be simply divided:

• Work on internal insulation baths;
• External insulation works.

Now in order of priority:

1. We thermally insulate the floor and foundation using one or a combination of several insulation materials: expanded clay, slag or stone wool, expanded polystyrene or other synthetic mats.

Most types of baths must be insulated from the inside. This will lead to fuel savings and more efficient and faster heating of the steam room.

Insulation from the inside is an inevitable event for most types of baths. It allows you to spend less fuel, warm up the steam room faster and better. Properly done insulation protects the walls of the bathhouse from fungus and rotting, and extends its service life. In this article we will select inexpensive and safe types thermal insulation depending on the material of the bath walls, and consider how to install them correctly.

We insulate the bathhouse

• Bath insulation
• Bathroom floor insulation
• Summarizing

Insulation of a bathhouse from the inside: materials

TO different rooms baths are presented different requirements, we will focus on the steam room and washing room, the features of which are high temperature and high humidity. Also, the insulation is selected depending on the material of the bath walls.

But, regardless of the material of the walls and the purpose of the room, the insulation must be:

• Non-toxic so as not to cause poisoning when exposed to high temperature;
• Not hygroscopic, so as not to absorb moisture;
• Resistant to high temperatures and steam;
• Non-flammable;
• Maintaining its shape even after several years of extreme use;
• Resistant to fungi and mold;
• Sold at a reasonable price.

Bath insulation

Insulation of the bathhouse ceiling from the inside

The bathhouse is insulated from the inside in the following order: ceiling - walls - floor. The main part of the heat in the bathhouse is lost through the ceiling, so

The thickness of the ceiling insulation is twice the thickness of the wall insulation and is at least 10 cm.

Regardless of the material of the walls of the bathhouse, the ceiling is insulated in the same way.

When insulating ceilings, foil is mandatory.

Insulation of a frame bath from the inside

For insulation frame bath Rolled mineral insulation is most often used.

The thickness of the insulation depends on the type of operation of the bathhouse: if you plan to heat it only in the summer, a layer of 5 cm is enough; if you plan to heat the bathhouse all year round, the insulation layer should be 10-15 cm (depending on the climate zone).
To insulate the walls of a frame bath from the inside:

• Insulation is placed in the interbeam space of the structure;
• The next layer is vapor barrier (foil);
• Ventilation gap;
• Sheathing.

Foil acts as a vapor barrier, so it is important that there are no even the slightest holes or damage in it, and that all joints are well taped with high-quality tape. The tape is always sold together with foil, and its quality must be checked in the store (glue the tape to the foil and try to tear it off).

Insulating a bathhouse from the inside with your own hands: log house

Insulating a chopped and well-caulked bathhouse from the inside would be a tragic mistake. This is not only pointless and destructive for the walls, it contradicts the very idea of ​​a chopped bathhouse.

Log houses for baths are made for two reasons:

1. To get classical Russian steam bath, which takes a long time to heat and maintains the required level of heat and humidity for a long time. It is the tree that accumulates heat and moisture and gradually “gives it away”. In this case, the inside of the bathhouse cannot be lined; You will also have to come to terms with the high consumption of firewood.
2. For the image. No bathhouse looks as cool in appearance as a chopped one. But I often don’t want to waste time and firewood; I want the bathhouse to be heated in an hour, so insulation, vapor barrier and clapboard cladding are done. The log house only works as outer frame, the meaning of the material is lost. In this case, it is cheaper and more correct to build a frame bathhouse.

It happens that a person already gets ready sauna from a log house, and various reasons she may be cold. Such a bathhouse can be insulated, but only from the outside.

The pie looks like this:

• insulation;
• wind protection;
• vertical sheathing to create ventilation gap;
• outer skin.

And you can put foil on the inside and line it with clapboard, not forgetting about the ventilation gap.

In a chopped bathhouse, only the floor and ceiling are insulated!

If the ceiling of a chopped bathhouse is made of thick boards, it is not necessary to use insulation, but then the following is poured onto the ceiling in a cold attic:

• ash;
• sand;
• expanded clay (it is preferable that the granules be different sizes);
• clay coating.

Insulation from the inside of a brick bath

Brick is not the best suitable material for the construction of a bathhouse, but if somewhere nearby there is brickworks, then brick baths begin to grow like mushrooms. Due to the high thermal conductivity of brick, such a bathhouse requires insulation without fail. Insulation is carried out only from the inside, and to make the bathhouse look cool from the outside, decorative jointing is done.

Usually the insulated wall pie brick bath looks like that:

• brickwork;
• waterproofing,
• insulation;
• vapor barrier;
• sheathing

Waterproofing between brickwork and insulation is optional: if the walls are built correctly and waterproofed from the foundation, they will not become damp. If there is no confidence in the walls, then it is better to do waterproofing.

Insulation on brick walls The bathhouse is attached to the frame.

Insulation of a bathhouse made of blocks from the inside

For the construction of a bathhouse, durable and moisture-resistant blocks of expanded clay concrete are preferred. The insulation of such a bathhouse is thought out at the stage of its construction. The most important thing here is to remove the icy mass of concrete from the heating circuit. There is a technology promoted by our user ZYBY, which allows us to solve this problem by constructing a frame wall from boards with an indentation from the walls of the bathhouse. It is suitable for insulating all baths with stone walls.

To ventilate and dry the space between the frame and the walls, several vents are made in the walls of the bathhouse, at the top and at the bottom outside. The vents are closed while people are steaming in the bathhouse; the rest of the time they are open for drying.

Insulation cake for steam rooms and washing rooms using this technology:

• concrete wall with vents;
• insulation on the frame-wall (with indentation from concrete wall);
• frame-wall;
• foil;
• finishing 50th unedged board(aspen, linden or cedar) to get solid wood in the steam room.

With this approach, there is no need to heat the ice walls. And the insulation will dry out between steaming sessions.

But many owners of a block bathhouse insulate it from the inside traditionally:

• concrete wall;
• insulation (attached to the frame);
• foil;
• ventilation gap;
• lining.

Such a bathhouse needs insulation from the outside as well.

Bathroom floor insulation

Precious bath heat it also goes through the floor, so it also needs to be insulated. To insulate the floor in a bathhouse, it is recommended to use expanded clay as the lightest and most environmentally friendly material.

Expanded clay is poured between layers of concrete floor as follows:

• pour the first layer of concrete;
• wait until it hardens completely;
• pour expanded clay (layer thickness - 10 cm);
• install reinforced grating.
• pour a layer of concrete;
• make a cement-sand screed.

Summarizing

Good bath - warm bath. And in order for it to warm up well to the required temperature, it is necessary to choose the right thermal insulation and insulate all structural elements.published
