Felt insulation for doors. Insulating a bathhouse from the inside: cheap and safe Insulating a steam room with felt

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, which are very different in their functions and require a certain approach in manufacturing. At the same time, standard insulation of a bathhouse with polystyrene foam 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 should definitely be sewn up to protect it from moisture.
IN Lately modern masters began to use special liquid formulations, which are simply applied in several layers to the surface and they provide excellent protection from the 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 the insulation of a steam room in wooden bath can be done 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 infrared radiation from escaping outside, 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 against 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 a general protection of the building, which quite copes with the task. However, the floors in these rooms should be additionally equipped with thermal insulation.

The fact is that people often walk on these surfaces barefoot. Taking this into account, some craftsmen advise installing a simple heating system. 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 special choice 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.

Good insulation for a bathhouse is the most important thing you should pay attention to when using it. interior design. After all, safety directly depends on its quality. bath procedures, and their comfort, and the durability of the walls themselves - especially in the steam room. But how to figure out which insulation is best for a bathhouse when modern market They offer almost a dozen types of them? Our article will help you with this.

So, back in Soviet times civil engineers made the following discovery: any homogeneous thick wall does not guarantee effective heat retention - because it itself will certainly absorb some of the energy. But here is a multilayer structure, in which there are different technical specifications materials – in terms of density, porosity and thermal conductivity – are very good at preventing heat loss, and such a half-meter “pie” can be compared in its performance to a wall one and a half meters thick. But the effectiveness of the “pie” itself depends precisely on what kind of insulation for the bathhouse was chosen.

Requirements for bath insulation

First of all, it is environmentally friendly, maximally resistant to moisture, well resistant to the growth of bacteria and fungi, and, finally, capable long years keep its shape well. And the most important indicator of the effectiveness of insulation is its thermal conductivity coefficient. The higher it is, the better the material itself. For example, mineral wool is still considered the warmest - its indicator is 0.045 W/(K*m).

In addition, there are additional requirements for insulation in a bathhouse:

It should work well with existing finishing and building materials, without in any way affecting their specific advantages.
Do not allow condensation to accumulate.
Have the lowest moisture absorption value.
Have a certificate of safety of use and full compliance with fire safety and sanitary and hygienic criteria.
Provide the ability to perform absolutely airtight thermal insulation.

Organic insulation

These are insulation materials that are made from plant or animal material: flax tow, shavings, cellulose, felt and others.

For example, today thermal insulation products made from peat, reeds and wood processing waste are quite popular. These are reed, chipboard and peat slabs, which are good for insulating the dressing room and rest room. They cannot be used in hot rooms - despite the fact that such materials are usually additionally treated with fire retardants.

Inorganic insulation materials

Such insulation is made by processing minerals. And they, in turn, are divided into:

Polymer insulation and their features

Polymer insulation materials include all those created by human hands - first of all, polystyrene foam. This material is like insulation for, if it has a second floor - it is light, comfortable and practical. It is easy for them to carry out all the work, it resists moisture well and tolerates high temperatures.

These are the types of this material today most often used for insulation: foam plastics, foam plastics with a foamy and cellular structure, cellular plastic insulation. The newest and quite popular option today is foam glass, which is easy to cut with a knife and saw, and convenient to attach to the surface. In addition, foam glass as insulation for the roof of a bathhouse embodies all the best from stone wool and foam plastic.

But it is still extremely undesirable to insulate the inside of a bathhouse with polystyrene foam - due to the fact that at high temperatures it begins to emit dangerous vapors of phenol, a particularly toxic substance. After all, only materials that are perfectly chemically clean and absolutely fireproof can be used for a bathhouse.

Mineral wool and glass wool insulation

This includes the famous mineral wool and more. In general mineral insulation are considered the most economical for baths. They are made from stone and slag fibers, so such mats can even be used to insulate the surface of a sauna pool.

But basalt insulation for a bath, diabase, dolomite, slag and limestone wool have their own priorities in that they are not flammable, have really high insulating characteristics, are durable, do not deform and are famous for their water-repellent properties. Installation with such cotton wool is quite simple and convenient, and the material itself is not to the taste of rodents. That is why basalt and stone insulation for baths today is one of the most preferred.

Its characteristics are close to basalt wool and glass wool - it is also more flexible in installation. However, its resistance to high-temperature effects is lower. As insulation for the walls of a bathhouse, it is quite suitable - but not for a steam room.

Advantages of foil insulation

Bathroom ceiling insulation is most often chosen with reflective characteristics. Among them, the so-called mirror insulations are quite popular today - they are supplemented with a special polished aluminum film that does not allow the most valuable radiation to pass outside the steam room - infrared thermal radiation. And such a “pie” is much more effective than conventional foil on cotton wool, which is often simply not able to withstand massive heat loss. In fact, this is an ideal insulation for the ceiling of a bathhouse, and not only that.

What insulation should I use for insulation between the crowns?

Insulation for baths and saunas can be not only internal or external, but also inter-crown. After all, the warmth in the bath itself depends on how densely the space is filled between the logs.

Thus, for a long time, materials such as red moss, cuckoo flax, sphagnum, wool felt, hemp hemp, flax tow and jute have been used to insulate a log bathhouse. But they are all very attractive to birds and insects, and therefore within a couple of years after insulation it is necessary to restore the thermal layer between the logs. In addition, if such inter-crown insulation also turns out to be under-dried, then it will begin to rot and simply pull the entire frame down with it.

Working with such materials is quite difficult - they dry out quickly during the laying process, and therefore all this takes a lot of time. That is why today builders are increasingly choosing new hybrid thermal insulators - combinations of jute and flax fibers. These are flax wool, flax jute felt, jute felt and fluffed spruce or pine wood. All of them fill gaps in the log house well and do not require re-caulking.

However, for each type of bathhouse, or rather, the material from which it is built, its own type of insulation is suitable. There is a separate interesting article about this on our website.

Today, before starting construction of a bathhouse complex, every owner should ask himself how to insulate a bathhouse from the inside. The construction market offers dozens of options. The main thing is not to get confused and choose such insulation for a bathhouse so that it meets construction requirements.

Principles for choosing insulation

When buying material, you should pay attention to the most important signs of an effective product:

environmental friendliness;
maximum degree of moisture resistance;
resistance to harmful microorganisms;
the ability not to deform during long-term use;
thermal conductivity index: the higher it is, the better;
compatibility with building materials;
minimum moisture absorption value;
compliance with fire safety requirements, sanitary and epidemiological standards;
ability not to accumulate condensate;
ease of installation.

Types of insulation materials

Before you run around the shops and grab anything, you should understand the range of materials on offer.

Bath insulation can be organic or inorganic.

Organic materials

This includes a group of insulation materials that are made from natural raw materials:

sheep wool or felt;
jute;
tow;
heat-insulating materials from peat, reeds and wood shavings.

Main advantage natural materials– environmental cleanliness.

But insulating a bathhouse from the inside with their help has a number of disadvantages:

Natural thermal insulation for the interior decoration of a sauna is a labor-intensive and time-consuming process.
Natural insulation materials are short-lived and require regular updating.
Flax, moss, felt, tow are a favorable environment for the life and reproduction of insects, rodents and other harmful microorganisms.
They are suitable for dressing rooms and rest rooms, but are not suitable for thermal insulation inside hot rooms, even after additional treatment with fire retardants.
Purchase natural materials significantly “hits the wallet.”

Inorganic or synthetic materials

There is no need to talk about absolute environmental friendliness here. Unlike natural ones, they will last for decades and provide better thermal insulation. Synthetic bath insulation is easy to install and resistant to high humidity and hot air.

Inorganic thermal insulation materials are divided into several types:

1.Polymer insulation

The group of these materials includes polystyrene foam, foam plastic, and cellular plastic insulation.

Polyfoam is easy to use to insulate the sauna ceiling. It does not absorb moisture, practical and easy to handle.

A novelty in the construction industry is foam glass, which embodies best properties polystyrene foam and stone wool. The material can be carved with a knife and attaches perfectly to the surface.

Despite the advantages, it is not recommended to insulate the ceiling inside a sauna with polystyrene foam. On the one hand, it is considered a fire hazard. On the other hand, as the air temperature increases, the foam deforms and releases bad smell, vapors of a toxic substance - phenol.

If you still decide to use polystyrene foam, then it is better to insulate the walls of the dressing room with it from the outside.

2.Basalt insulation for baths

Made from mountain wood, the material is used in last years demand. It has a number of advantages:

Not subject to combustion;
Resistant to humid air;
Does not deform under the influence of temperatures;
Excellent sound and heat insulation;
Service life up to 30 years;
Does not cause any difficulties during the installation of finishing.

As for the disadvantages, there are none except for the cost of the material.

3.Mineral wool

The main difference between the technology for producing mineral wool and the production of insulation from basalt fibers is the use of inexpensive industrial waste.

This has a positive effect on the price of the material, but negatively on the mechanical strength of the insulation. Therefore, be extremely careful during the installation process.

Along with the disadvantages, mineral wool is not without advantages:

Reliable thermal insulation;
Not afraid of moisture;
High degree of sound insulation.

4.Glass wool

Insulating a bathhouse with glass wool will cost no more than its analogues. And according to certain criteria, it is not inferior to other materials: it holds heat well and is easy to install.

A significant disadvantage of glass wool is its instability to hot air.

5.Foil insulation

To insulate the sauna ceiling, it is recommended to use materials that reflect light. Insulating mirrors have become widespread. Due to a special aluminum coating, they reflect and do not transmit heat through the ceiling. Foil insulation for a bathhouse is recommended to be used in combination with classic materials.

Insulation of the sauna

Having decided on the choice of one or two heat-insulating materials, proceed directly to work. Insulating a bathhouse from the inside with your own hands is a difficult process that requires skills in the construction industry. If you are confident in your abilities, then go for it. Otherwise, it is better to seek the help of specialists from the Marisrub company.

It should be noted that the process of thermal insulation of a wooden or brick sauna is almost the same. Therefore, there is no point in focusing on the insignificant difference.

Before you start insulating the walls, ceiling and floor, it is wise to take care of the vapor barrier. Even if you have chosen moisture-resistant insulation, during operation condensation will gradually begin to penetrate through the internal layers of the insulating material and have destructive effects.

To isolate the insulation from moisture, use aluminum foil. The solidity of the vapor barrier is achieved through metallized tape, which is used to glue the joints of the foil sheets.

We insulate floors

It is correct to start insulating a sauna not from the ceiling or walls, but from the floor. In the bathhouse it can be continuous or leaking. Considering that structures differ from each other, insulation of each type occurs differently.

It is better to use mineral wool. It is laid on a subfloor made of boards and covered with a layer of waterproofing. The last stage is pouring the floor.

When installing leaking floors, dig a pit 50 cm deep and fill it with 5 cm of sand. After careful compaction, a 20-centimeter layer of insulation is laid - polystyrene foam, which is poured cement mortar with foam chips.

After drying, the concrete is covered with a layer of waterproofing, not forgetting the walls.

Then they again fill it with cement and vermiculite, spread a reinforcing mesh and cover it with a layer of concrete with fine crushed stone. On at this stage the work makes a slope in the direction where the water will flow.

The work is completed by laying the finished floor on posts.

We insulate the walls

Insulation of bathhouse walls from the inside occurs in stages:

1.Using wooden slats or timber we apply lathing to the surface of the walls. The gap between the slats must be made smaller than the width of the heat-insulating material.

This is done so that the insulation fills the resulting spaces and prevents the formation of bridges for cold air. It is recommended to use mineral wool or basalt fiber slabs as insulation.

2. Having laid the heat insulator, cover it with any vapor barrier with foil. In this case, the reflective side of the aluminum surface is located inside the sauna.

The vapor barrier is placed between the slats and fixed to them.

Thermal insulation of the steam room walls is ready! Other sauna rooms are insulated using the same principle. Instead of foil for a vapor barrier, thick kraft paper for wrapping is suitable.

When insulating buildings made of bricks or blocks, the thickness basalt insulation It is advised to increase it so as not to lose heat.

We insulate the ceiling

Thermal insulation of the ceiling occurs by analogy with the principle of wall insulation.

According to the laws of physics, the closer you are to the ceiling, the hotter the air will be. Therefore, fire-resistant insulation is chosen for the ceiling. Mineral wool is perfect.

If there is an attic in the bathhouse, then a vapor barrier layer is made above the insulation - an aluminum film.

Insulation is placed under, above or between the rafters. If you're looking for the easy way out, lay a continuous layer of insulation between the rafters.

Finally, cover the heat-insulating material with a layer of waterproofing. Do not forget about the air gap of 20 mm. This is done taking into account the increase in insulation by a third of the width under the influence of moist air.

If there is no attic in the bathhouse, expanded clay is often used as insulation for the ceiling. A 25 cm layer of thermal insulation is poured onto the vapor barrier layer.

The construction market offers for insulation bath room thermal insulation panels. The main advantage of the material is the possibility of refusing waterproofing, the minus is that they require a reliable vapor barrier layer.

Done correctly interior decoration Baths guarantee not only a pleasant stay in the company of friends, but also safety. Therefore, approach the selection of building materials and the performance of work with maximum responsibility.

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.

Summarizing

Insulation of a bathhouse from the inside: materials

TO different rooms baths have different requirements, we will focus on the steam room and wash 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	In what room is it used?	Note
Natural materials: rolled jute, felt, insulation made from reeds and sawdust, moss, tow, etc.	Dressing room, rest room.	Natural materials ignite at high temperatures, so they are not suitable for steam rooms and washrooms. But materials made from jute and flax are the best inter-crown insulation for a chopped bath. There are excellent modern roll insulation made from natural materials, but they are very expensive, so they are practically not used for insulating baths.
Mineral insulation.	They can insulate any bathhouse. Most often, slab insulation boards (mats) that are easy to install are used.	They do not rot, last up to 30 years, are fire resistant, and inexpensive. Most Russian baths are insulated with these materials.
Polymer materials	It is not recommended by craftsmen for insulating a steam room.	Polystyrene foam is an excellent heat insulator, but it is flammable, and at high temperatures it releases substances harmful to humans. You cannot use polystyrene foam in the steam room.. Extruded polystyrene foam or penoplex is considered a safe material (it is used to insulate the bathhouse of Russian polar explorers in Antarctica). But experts also do not recommend using this material in a steam room.
Insulation based on aluminum foil.	It is used in accordance with the manufacturer's recommendations for a specific room.	The principle of operation of such insulation is the effect of a thermos, the reflection of heat from the walls and ceiling due to foil. Some types of foil insulation are produced specifically for steam rooms and other rooms with high temperatures, while others begin to emit when the temperature rises. harmful substances. Foil in the bathhouse is used as a vapor barrier.

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;
Next layer– 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:

To get a classic 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.
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 works only as an external 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 gets a ready-made bathhouse from a log house, and for various reasons it can 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 there is a brick factory somewhere nearby, then brick bathhouses 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 with 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 also escapes 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;
expanded clay is poured (layer thickness - 10 cm);
install reinforced grating.
pour a layer of concrete;
make a cement-sand screed.

Summarizing

A good bath is a warm bath. And so that it warms up well until desired temperature, it is necessary to choose the right thermal insulation and insulate all structural elements.published

The steam room is the main element of the bath, its very essence. In order for the steam room to be truly hot, it is important to thoughtfully approach the process.

Incorrect actions or incorrectly selected materials can lead to the steam room taking a long time to heat up or giving off heat too quickly.

In addition, all materials must meet safety and environmental requirements.

Let’s make a reservation right away that different types of bathhouses need to be insulated in different ways, so here is an overview of the materials, and for details on insulation and bathhouses, see the relevant materials on the site. Technologies are also presented in separate materials. More information on different types See insulation for baths.

How to reduce heat costs

You can avoid additional costs for insulating a bathhouse if you take care at the construction stage:

Insulation for sauna steam room: 4 layers of insulation

Water protection aimed at isolation interior spaces from moisture from outside. Needed for frame construction and for aerated concrete walls.

IMPORTANT! You should choose different solutions for waterproofing the steam room and other rooms. Waterproofing materials for steam rooms should be made from materials that can withstand the highest temperatures (for example, based on kraft paper).

Insulation The steam room should be aimed at reducing heat loss and creating a “thermos” effect. Then all the heat will remain inside the steam room, and not warm environment. Therefore, when choosing insulation for a bath, the steam room requires the closest attention.

Finishing materials They allow you to hide flaws during construction, in addition, they provide a beautiful visual appearance of the steam room.

REFERENCE. The market mainly presents Decoration Materials from such tree species as: pine, linden or aspen. This wood has a low density, so we recommend using narrow boards and placing them horizontally to eliminate the risk of warping. In addition, it is imperative to treat them with oils or other specialized compounds to extend their service life.

Insulation for a steam room: types

There are different types of insulation used for installation on walls, ceilings and floors. Separate articles are devoted to materials used for and.

For walls

Everything can be divided into two categories:

– natural;
– artificial.

Natural

Natural materials are made from natural raw materials:

sphagnum(scope of application: );
tow(scope of application: eliminating cracks);
building moss(insulation of steam room walls).

Artificial

To popular artificial materials relate:

extruded expanded polystyrene;
Styrofoam.

These insulation materials are characterized by high resistance to damage, have a long service life and high degree thermal insulation.

basalt wool.

Is different high quality, ease of installation and low cost.

For the ceiling

Traditional

For . For example, it is still used for steam rooms; it is used to coat the ceiling of the steam room from the attic side

Common application bulk materials such as: expanded clay, sawdust, slag, etc. A layer of earth must be poured onto the sawdust to ensure fire safety. And the expanded clay layer should be at least 30 cm.

Modern

For ceiling insulation, the following are better suited:

basalite (slabs of low-density basalt fiber);
isospan (there are 2 types):
– isospan A (barrier type against wind and condensation, installed outside the insulation);
– isospan B (barrier type against steam, installed indoors, protects the insulation).

The ceiling can also be insulated with regular foil, the layers of which must be overlapped.

For floor

In the steam room you can use:

– expanded clay synthetic slabs(easy to install);
– loose expanded clay(also easy to install, but hygroscopic);
– penoplex ( IMPORTANT! The brand you choose should have high compression loads).

Conclusions: what insulation to use for a bath in a steam room

Artificial materials are more resistant to high temperatures and humidity, but may lose their insulating properties over time due to constant heating and exposure to moisture.

Despite the variety of materials available from manufacturers, you should first of all focus on the safety of the materials, and not on the cost, because... a steam room is a place where the materials used are constantly exposed to high temperatures.
