Insulating the ceiling of a bathhouse the old fashioned way with Asoka. Insulation of the bathhouse ceiling with earth. Internal and external insulation of the bathhouse ceiling


When arranging a cottage or country house The task of building a bathhouse often arises. The classical bathhouse has developed a number of specific traditions that go back to ancient times. Previous generations created proven construction and finishing technologies. Thanks to these techniques, the bathhouse has unique healing properties. Today we’ll talk in more detail about how insulate the bathhouse ceiling.

Ceiling insulation

During construction baths, installation and insulation of the ceiling is considered one of the important points. What affects the ceiling? In the process of using the bathhouse, it undergoes a number of aggressive influences. Conditions are created inside the steam room high humidity and air temperature. Hot steam rises to the ceiling, and if there is little heat transfer through the ceiling, the space inside the bath will not warm up, and bathhouse will not serve its intended purpose. There are many ways to insulate ceilings, let's look at some of them.

The old way insulate the bathhouse ceiling

A solution of about 5 cm of dough-like clay with the addition of chopped rye straw is spread on the tongue-and-groove boards from the attic side. After drying, the clay cracks. This dried layer is rubbed with a solution made of clay and sand. When both clay layers are dry, a sand cushion 10-12 cm thick is poured on top. The clay-sand layers serve to absorb excess moisture that is formed from wet steam. Due to the high temperature in the bathhouse, when there is no steam, the clay layer dries out and retains heat in the bathhouse.

Backfill method

Tongue boards are nailed to the beams. They need to be oiled. A layer of boards with moisture gaps is attached to the tongue and groove boards. A layer of waterproofing is laid on top. A 20 cm cushion of bulk types of heat insulators is poured onto the waterproofing layer. It can be slag, sand, or a mixture of sawdust and clay. A good option With this method of insulation, filling with expanded clay granules is considered.

Combined method of insulation bathhouse ceiling

The ceiling is covered with thick boards, the thickness of which is 7 cm or more. A vapor barrier is laid on the boards (waxed paper, dry cardboard, foil). Then a pillow is made of soft clay, on which a 15 cm thick insulation is laid.

Various organic and mineral heat-insulating substances are used as insulation. For example, sawdust with clay, expanded clay, modern mineral fibrous materials. A sand-cement screed is made on top of the thermal insulation, and a flooring is made on top. On mineral wool additionally lay film or fiberboard sheets.

Combined method with sawdust

Two layers of boards are screwed to the beams using screws, the first layer consists of edged boards, and the second (from the inside) is a finished lining made of aspen leaving gaps. Cardboard is laid on top of this structure from the attic side, and a 2-5 cm layer of clay mixed with sawdust is placed on top of it. Next layer – 15 cm basalt insulation. This whole “pie” is covered with film and attic boards.

On modern construction market You can find a great variety of insulation made from jute, flax fiber and other materials. Good feedback There are reports of jute felt, which does not emit harmful substances.

There are several ways how to insulate a bathhouse ceiling. I will be glad if I helped you with advice.

When building a bathhouse, you need to pay attention to the insulation of the structure. If heat constantly leaks out, it will not be possible to create the desired temperature in the steam room.

Many people believe that we can limit ourselves to insulating the walls and floor. But the heated air becomes lighter, rises and penetrates through the ceiling and roof. Insulating the bathhouse ceiling will help stop heat loss. You can carry out the installation yourself, and in the future you will not spend money on heating the air around the house. Insulating structures will not allow heat to dissipate.

Why is the ceiling insulated?

Warm air always rises, so insulation is very important. Click on photo to enlarge.

We have already mentioned that warm air accumulates in the upper part of the room.

If the ceiling and roof slopes are not insulated, the heat melts the snow on the building.

Cold and humid air penetrates into the room along the foundation walls.

The design of the ceilings in the bathhouse must be such that it can support the weight of the insulating structure.

It is also important that the ceiling materials are not damaged by moisture.

After all, there is always high humidity in the bathhouse.

Well, the last requirement is that the ceiling must not allow heat to pass through.

What ceiling to make in the bathhouse

Typically, in bath rooms, the ceiling height ranges from 2.10 to 2.30 m. The higher the ceilings, the more difficult it is to warm the rooms. In buildings with high ceilings, warm air accumulates at the top, leaving the floors cold.

The ceiling in the bathhouse should retain heat. It is also important that the flooring materials are not damaged by moisture. Therefore, a multi-layer ceiling is constructed in bathhouses.

Here is an approximate diagram of such a design: on the attic side the floor is covered with boards, film or parchment is stretched under the boards for waterproofing. The next layer of the cake is insulation; the insulation underneath is protected from steam by a layer of film or parchment.

On the side of the rooms, the ceiling is usually finished with wood.

False ceiling installation

How to cover the ceiling of a bathhouse from the side of the room. Typically, different types of wood are used for this. In conditions of extreme humidity, coniferous varieties have proven themselves well. You need to ensure that the wood is well dried.

It is better to select boards without knots and cracks for the ceiling. In addition, any wood should be treated with a protective impregnation. Then the structure can last a long time even in a humid environment.

The whole structure false ceiling rests on the floor beams. A frame is laid on the beams, on which boards are laid. A vapor barrier is laid on the boards below. Insulation mats are tightly laid on top of the vapor barrier, and they are again covered with films on top. A plank floor is laid on top of the pie.

Advantages of this design:

  1. ease of installation, the owner of the building can perform all the work independently;
  2. the structure is not heavy, the floor beams can support its weight;
  3. The wooden structure will last a long time.

The disadvantages of this option include its price. High-quality wood is now expensive.

Panel ceiling installation

The insulated ceiling resembles a layer cake. Click to enlarge.

The floor structure is assembled from ready-made panels. Pieces of moisture-resistant insulation are placed between the panels.

The prefabricated panel is based on load-bearing bars onto which edged boards are placed.

Insulating material is tightly laid inside the board panel, lined with vapor-proof materials.

Advantage panel structure– You can use illiquid lumber to make panels.

Flaws:

  1. the shields are heavy, you won’t be able to install them yourself;
  2. a heavy structure can deform the floor beams, so you need to calculate the weight of the insulating structure and, if necessary, strengthen the beams.

Installation of a flat ceiling

In this case, the ceiling is covered with a layer of thick boards. The boards, more than five centimeters thick, rest on a brick ledge or the last crown of the frame. The boards are covered with films, on top of which insulation mats can be laid.

This ceiling can only be installed in a small bathhouse.

The advantages of this option include ease of installation and low cost of construction.

Disadvantages: the design is only suitable for a small room; the insulation will not be protected and the attic space will not be usable.

How to insulate a bathhouse ceiling

Let's look at the main ways to insulate a bathhouse ceiling.

Just like in the old days

In the past, it was common practice to insulate the bathhouse ceiling with clay. Insulation material can be dug up near the house. Clay is easily applied to any surface and can last for a long time.

The insulation structure is constructed as follows: laid on the floor beams wooden boards. The clay is mixed with sand and filled with water; from the attic side, the boards are covered with a liquid mixture. The structure is left alone until completely dry.

Afterwards, the clay layer can be covered with a layer of sawdust or dry leaves, even dry soil.

Insulation with clay will require a lot of effort; the work is troublesome and dirty. But the structure can be built without financial investment.

Expanded clay

Expanded clay is very cheap material. Click to enlarge.

Expanded clay is a bulk material.

Expanded clay granules are made from clay.

The material is expanded and fired.

Air cells are sealed inside the granules, which cause the low thermal conductivity of the insulation.

It is better to build a sheathing of wooden blocks on the attic floor for insulation.

Expanded clay is poured between the bars, in a layer of about thirty centimeters.

The material must be limited from the access of moisture from above and from steam from the side of the steam room.

Design disadvantages:

  1. you will need an impressive layer of expanded clay, the structure will be heavy;
  2. you will have to lay boards on the expanded clay to walk around the attic;
  3. It is important to insulate the insulation from moisture.

Mineral wool

Mineral wool is second only to polystyrene foam in its popularity. We cannot recommend combustible foam for bath insulation. But fibrous insulation made from molten basalt rocks is ideal.

Cotton wool retains heat well and does not burn. The material is safe for health and inexpensive.

A significant disadvantage of vata is hydrophobia. When the cotton insulation gets wet, it crumples and its weight increases. Wet wool loses its low thermal conductivity qualities. It is very important to securely cover the insulation layer with films to completely eliminate the access of moisture.

Sequence of work on ceiling insulation

Let us describe the structure of a false ceiling, since it can be completely assembled with your own hands: first install the load-bearing beams, the wood must be treated with an antiseptic; It is better to lay the beams along a narrower span of the box.

Vapor barrier films or membranes are attached directly to the floor beams; it is better to cover part of the wall near the ceiling with film.

Ceiling boards for interior cladding are laid; when laying insulation boards, it is important to place them end to end, all cracks can be filled with foam.

A waterproofing film is stretched over the insulation cake; it is better to cover part of the wall as well; It is important to leave a small gap between the film and the insulation boards so that the air circulates and takes away any remaining moisture. The attic floor is laid, usually from edged boards.

How to insulate a steam room

When building a bathhouse, all structures need to be insulated: foundation, walls and ceiling. But the steam room needs additional insulation. The temperature in this room must be kept very high level. At the same time, steam rooms often contain a lot of steam and moisture.

How to effectively protect small room from heat loss?

It may be recommended to additionally insulate the walls and ceiling of the steam room with new materials, such as polyethylene foam. This insulation contains air bubbles firmly sealed in polyethylene capsules. The outside of the material is covered with aluminum foil.

Insulating the ceiling of a steam room with polyethylene foam reliably insulates the room from heat loss. Aluminum foil reflects almost all the heat rising to the ceiling.

For efficiency, you can combine several insulating materials over the steam room. For example, build an insulating structure from mineral wool, and lay sheets of foamed polyethylene covered with aluminum foil as waterproofing.

It is important to turn the insulation with foil inside the room so that the material reflects heat.

Having completed the work on insulating the bathhouse, it is important to check the operation of the ventilation. There will be a lot of moisture in the bath. It is important that she can leave the premises. We covered the walls and ceiling of the building with insulation and films.

Steam will not be able to penetrate these structures. Excess moisture will destroy the tree. Therefore, it is important that ventilation and hoods work properly.

If you are planning to build or repair a steam room yourself, then most likely you have wondered: what is the best way to insulate the ceiling in a bathhouse from the inside and how to properly cover it with your own hands, and also looked for examples with videos.

Why is this necessary?

A person in a steam room often encountered such a phenomenon as condensation. It is formed when hot steam rises and drops of water appear in the room. It doesn’t matter whether the steam room is built into the room or is a separate structure, it is necessary to insulate it. The only question is how and to what extent. If it is built into the room, excess heat can go into the house. Therefore a thermal camera is required.

Wooden parts of the structure are most exposed to the aggressive effects of high temperatures and moisture. Therefore, the coating must be of high quality to ensure an “impeccable” microclimate in the steam room.

To make wood last longer, it is impregnated various compositions(additives – fire retardants). They increase durability. This safety measure is justified, because the temperature in the steam room reaches 100°C. However, chemical anti-mould coatings will produce toxic fumes at high temperatures.


Main "ally" wooden coverings– insulation, which should retain hot steam inside the room and prevent the development of rot. It protects the wood from condensation, prevents wood from rotting and extends its service life.

Proper insulation of the ceiling in a bathhouse or steam room with your own hands involves observing the following points:

  1. Steam must accumulate and remain indoors.
  2. The inside of the roof must be protected from high humidity.
  3. It is necessary to prevent the occurrence and accumulation of condensation both in the steam room itself and in the ceilings under the lining in the walls and ceiling.

Features of insulation

Not all products are used for insulation. Plastic products will deform from high temperatures. If you use plywood or fiberboard, then from the hot air they will begin to expand and change shape, accumulating moisture. These products are definitely not suitable. The best way finishing is considered to be several layers:

  1. The first step is to use an insulating material that prevents water from penetrating.
  2. Place a second layer of insulation (for example, mineral wool).
  3. The third level is aluminum foil.

This “multi-layering” holds heat well and does not allow steam to escape for a long time, so heat losses are reduced.


Insulation materials can be divided into the following types:

  • fibers;
  • plates;
  • blocks;
  • wall slabs;
  • backfill.

And depending on the composition they distinguish:

  • Organic such as ecowool.
  • Inorganic - mineral wool.
  • Expanded polystyrene.
  • Other insulation materials are such as technovent and technoblock.

Functions of bath ceiling thermal insulation


High-quality insulation material must be:

  • heat-resistant to prevent fire;
  • environmentally friendly (should not emit harmful fumes);
  • “breathe” so that water does not collect and condensation does not accumulate;
  • resistant to moisture.

Types and design features

First you need to find out what kind of roof you have - with or without an attic. Structurally similar options for buildings made of logs and panels. They have:

  • steam insulation;
  • insulation;
  • hemming boards;
  • beams
  • sheathing

Vapor barrier is applied to the wall and ceiling, then timber, then insulation. You can use basalt wool in the form of mats, then again a layer of vapor barrier, then a block and fastening the lining. As an option, respectively, 40 mm timber and 40 mm insulation. You don't need too much insulation. Excessive consumption of materials in this case is inappropriate.

On the ceiling, the structure must be made with a slope to collect condensation. As a result, there remains space under the lining, allowing the bathhouse to dry out. Power modern oven enough to warm up the bath well. Ideally, the steam room is dried by ventilation and a fuel-processing furnace.

If there is no attic, then you need to perform additional steps:

  • coat the entire lining with clay with a layer of up to two centimeters to reduce heat loss;
  • sprinkle the coating with a mixture of cement and wood chips (you can use slag up to 15 cm - this measure helps eliminate condensation).

If you want to make a properly functioning steam room, then you first need to take care of vapor barrier (not waterproofing with vapor permeability) of the ceiling to create a steam pocket up to the level of the top edge of the door to retain steam and create humidity in the region of 60%.


Vapor barrier of floor beams and the entire ceiling pie is a consequence, not a cause. Ceiling insulation without foil is completely irrelevant, since the steam room will not perform the functions that are assigned to it. If you need a steam bath, and not a sauna, you will have to open the casing and do a vapor barrier on the ceiling. If this is not done on time, then after a season or two you will have to replace damp insulation and rotten beams.

To protect wall structures, regardless of what they are made of, it is necessary to insulate the outside to prevent moisture in the form of condensation at the dew point from entering the material. For the Russian type of bathhouse, insulation of the walls from the inside is not necessary, since it is possible to create a regime of 60° and 60% even with leaky walls, but with a well-waterproofed ceiling and volumetric brick oven with a powerful thermal core inside. Ideally, put foam glass insulation on top of aerated concrete walls in 50 mm thick slabs, and then plaster and decorate with wood.


Flat ceiling

He is not seen as often as before. The use of hewn round timber is widespread. This method was previously considered the most profitable - people only had to go into the forest and chop everything they needed for construction themselves. This is currently the most expensive option.

There are several installation options.

  1. Along the crowns of the log house, if the room area is small (length no more than 2.5 m). Boards of small thickness (50 mm) are used as flooring; an even more economical method is edged tongue-and-groove options (25 mm).
  2. Eat interesting option coverings with unedged sanded boards. They are laid in 2 levels. Gaps and irregularities of the first level are covered by the second level.
  3. On the floor beams. With this option, the area of ​​the room can be larger. An accent on the beams will add flair and look great.
  4. On load-bearing frame from slats. Suitable for small spaces and used less frequently. Make it easier. But if the room has an attic, then it cannot be used. The roof may not be able to handle the heavy load.


The process takes place in several steps.

  1. The attic is lined with a vapor barrier film (PIP) with an overlap of 10-15 cm (foil surface down).
  2. Mineral wool is placed on top of it (instead, the surface can be covered with expanded clay or covered with a mixture of sawdust and clay).
  3. The work is completed by laying a waterproofing film (WIP) - roofing felt or polyethylene.

False ceilings

They have bearing capacity, they are often used as an attic, and their installation will cost you much less.


To make this coating, you need to install the beams in advance. Then boards or panels of tongue-and-groove boards are evenly laid on them. This structure is insulated with fibrous material. The installation process will take place in stages:

  1. The GIP is taken and laid on the beams from the roof side. This is done overlapping.
  2. Boards or sheets of plywood are placed on the waterproofing.
  3. Mineral wool is laid between the beams. Its thickness varies from 150 to 250 mm (depending on the climate of the area). All joints must be covered with another sheet.
  4. We attach a vapor barrier to the bottom of the beams.
  5. Then we attach the wood slats.
  6. On last stage the lining is attached.

After completing all the work, you will receive extra bed for storage - attic or attic.


Panel ceiling

It's difficult to do on your own. To begin with, a special structure is made from panels. Then it needs to be fixed on top cross beams or on the top of the wall. How the installation works:

  1. Boards are placed closely on the supports (perpendicular).
  2. Then on inner side PP we attach narrow boards, they will be the sides.
  3. The next step will be laying the PIP.
  4. We put ecowool (or any other) into the resulting space of the panels.
  5. Then you need to put a film of polyethylene or roofing felt.
  6. The final stage will be the installation of the boards; they will be the future floor.

Insulation for the ceiling in a bathhouse: which material is best suited

Previously, it was customary to use natural raw materials such as moss, clay, sawdust, straw or earth.

Now people have begun to use the most effective coatings. They make all the work easier, even if you are not a professional builder. For example, it is widely used:

  • basalt wool;
  • expanded clay;
  • penoizol;
  • ecowool and others.

You can also use polystyrene foam and glass wool. But when heated, the former emits harmful gases and can ignite. A good protective suit is recommended for working with fiberglass.


The question is whether or not to insulate the entire building only inside or on both sides. There are many opinions on this matter, but the truth is in the middle. There are many additional factors you need to know:

  • this is a Russian bath or sauna;
  • what material is the bathhouse built from?
  • what kind of stove does it cost?

How to insulate outside

To keep the steam inside and not escape outside, you need to achieve a “thermos” effect. Insulation must be both inside and outside the building. To achieve this effect, you will need insulation for the ceiling in the bathhouse. There are different options:

  • waterproofing film;
  • expanded clay;
  • mineral wool or others.

Builders create a “multi-layer cake” from these elements. Blocks are used on the roof side. PIP is placed on top. And the last layer is expanded clay, fibrous and other materials.


How to insulate from the inside

Let's look at some modern views insulation:

  • expanded clay;
  • mineral wool;
  • ecowool;
  • foamed polypropylene;
  • penoizol;
  • growing aerated concrete.

Mineral wool

It has a fibrous structure that looks like ordinary cotton wool. During the production process, a crushed mixture of various rocks (basalt, dolomite, limestone) is added to it. This cotton wool is very popular due to its properties:

  • long service time;
  • good hygroscopicity (excellently absorbs water);
  • resistant to overheating (fireproof).

The thickness of the wool is from 20 to 25 mm. The efficiency is much higher if it is placed on PIP. To work with it you need a thick suit and rubber gloves.


Foil insulation

It is perfect for insulating the ceiling in a bathhouse. Metal spraying retains heat and provides good vapor barrier. This is economically beneficial because little fuel is required to heat the room. This insulation is presented:

  • mineral wool with aluminum film (produced in rolls and slabs);
  • polymer fabric based on foil (has a small thickness, produced in the form of rolls).


Foil has 2 purposes:

  • reflect IR rays;
  • protection (waterproofing or vapor barrier) of the ceiling from moisture and rot.

This insulation resists high temperatures, is easy to cut, and does not emit toxic fumes. But if the entire steam room is packed in foil, then it is absolutely not vapor-permeable. Therefore, the room turns out to be not comfortable (heavy), like in a greenhouse; therefore, in such a bathhouse it is necessary to do proper ventilation.

Expanded clay

By appearance resembles small clay stones that have pores. Absorbs water abundantly, which is its weak side. It is used in combination with steam and waterproofing materials. Expanded clay also has many advantages:

  • environmentally friendly product, without foreign toxic impurities;
  • does not ignite;
  • has a long service life;
  • bacteria and fungi do not form in it;
  • cheap product;
  • it's easy to use.

Penoizol

It is foam plastic in liquid form, it is classified as thermal insulation materials. It fills all areas (even hard-to-reach ones). It has many advantages:

  • cheapness;
  • excellent quality (does not expand when it dries);
  • does not ignite;
  • lasts a long time;
  • Mold and mildew do not form on it.

Cement and sawdust

This method of insulation is characterized as “old-fashioned”. To do ready mixture, you will need 10 parts of sawdust, one of lime, and one of cement. Then add 1.5 parts of water to get the finished product.

The solution is evenly distributed over the entire surface. This is an economically profitable option, since the cost is very low. In addition, the resulting solution is environmentally friendly. Minuses:

  • it is difficult to prepare;
  • thermal insulation properties lower in comparison with other options;
  • no protection against mold;
  • When dry, cracks appear that need to be greased.

Ecowool insulation

Enough effective method heat preservation. Environmentally friendly fibrous pulp made from cellulose. It contains added substances that improve its properties: boric acid, sodium tetraborate. Thanks to them ecowool:

  • fire resistant;
  • resists the development of bacteria;
  • prevents the appearance of insects and rodents.

It is also lightweight and spreads over the entire area, filling the voids. Its main disadvantage is moisture absorption. This reduces thermal insulation.

Features of insulation products

Manufacturers offer various membrane films that protect materials from high humidity. Experienced builders recommend purchasing vapor barrier upholstery with a reflective foil layer that does not allow heat to escape. The following types with a foil layer are distinguished:

  • polypropylene;
  • kraft paper;
  • roofing felt;
  • membrane;
  • foil;
  • coating

This film is installed with a large overlap (10-15 cm), and the joints are taped with foil tape for construction work.

In specialized departments of stores there is a wide selection of waterproofing products - foil-coated kraft paper, construction membrane and other products. Although you can save money and purchase regular plastic film or roofing felt.

How to insulate concrete floors

If you are completely confused in the wide range and do not understand what material to use, then take advice experienced builders. For example, with concrete floors it is recommended to use expanded clay.

Special preliminary preparation not required. For convenience, timber slats can be attached to the base of the roof. This will make it easier to check the uniformity of expanded clay distribution. Although this condition is advisory in nature.

So, pour expanded clay (30 cm thick) over the entire surface. Ordinary granules will help distribute the granules evenly. garden rake. If the attic space will be used in the future and a floor is provided, then expanded clay is laid level.

If all the backfill is leveled, you need to lay the GIP. Durable polyethylene is quite suitable. It is distributed with an overlap of 10-15 cm. Scotch tape is glued to the joints.

If you want to make a floor, then planks are laid on the beams.

This is a fairly cheap and easy-to-follow method that will help you insulate the ceiling in a bathhouse with your own hands. But because it is cheap, it does not become less effective.

Installation of thermal insulation

To achieve the main goal - accumulation and “saving” of steam, you need to make 2 layers of PIP and 1 additional layer for thermal insulation. This measure will make the room warmer and more comfortable.


Experts advise placing layers perpendicularly. This arrangement will increase the strength of the entire structure and help avoid severe deformation. If you use mineral wool and clay, the process will take place in several steps:

  1. is taken unedged board(5 cm) and is attached to the bottom of the beams;
  2. to support the filing, we fix the flooring along all the bases;
  3. tongue and groove slats made of aspen are attached to them (taking into account the gap for ventilation);
  4. We lay vapor barrier material on the outside of the roof;
  5. spread mineral wool 15 cm wide over the laid mixture;
  6. then we lay polypropylene film;
  7. We place boards on top of the resulting structure; this is the future floor of the attic.

If everything is done correctly, the end result should be an excellent steam room. All the steam will remain inside for a long time, and the steam room will not cool down for a long time.

Dry insulation method

Specialists Sosnin Yu.P. and Buharkin E.N. In their book they offer the following method:

  1. we take tongue and groove boards (25 mm) and fasten them to the beams, then treat them with drying oil twice so that they become moisture resistant;
  2. we sheathe them, maintaining a moisture gap of 3 cm;
  3. spread a film on top (polyethylene, roofing felt, and better coverage made of foil with reinforcement);
  4. the next layer can be sand or slag (20 cm thick).

If you properly insulate the ceiling in a bathhouse, following the recommendations and observing technological process, That:

  • heat loss will be significantly reduced (up to 35%);
  • there will be no fungi or pathogenic bacteria on the surfaces of the steam room;
  • less firewood will be required;
  • the steam room will last you longer.

Besides these positive points, there are others:

  • you can do this work with your own hands without large investments;
  • select all the materials that suit you in terms of price and quality.

And the best part is that you and your loved ones will be able to spend time pleasantly and comfortably in your updated sauna.

A sauna or bathhouse is a type of room in which it is necessary to provide sufficient high temperature, and most importantly, preserve the achieved microclimate for a certain time. In order to achieve this effect and understand how to properly insulate a bathhouse or sauna, you need to study some common truths. How can warm air leak from a bathhouse? Mainly three options are considered:

  • leakage of warm air through cracks in the ceiling;
  • exchange of heat from already heated objects with cold ones;
  • intersection of homogeneous barriers by thermal air flows.

If you lay a thermal insulation layer in the ceiling structure in a bathhouse, you can cope with all three aspects, provided that the insulation process is carried out correctly. If mistakes are made, this can lead to the formation of condensation. In this case, you will have to spend more energy resources to heat the bath or sauna.

Methods of thermal insulation of a bathhouse ceiling

Many steam lovers are wondering how to insulate a bathhouse or sauna. There are several ways, both using modern materials and those materials that our great-grandfathers used. Process modern insulation easier, but not all materials are affordable. WITH traditional ways Insulation will, of course, have to be tinkered with, but the costs are much lower and the materials used are environmentally friendly. If preference is given to modern material, then it should be taken into account that its cheap types are not suitable for insulating a bath. When heated, they begin to release toxic substances, and in the vicinity of the furnace, they generally begin to melt. Such materials include polystyrene foam and polystyrene foam. It is not recommended to use glass wool for insulation of baths. We will present several options for proper insulation of the ceiling of a bathhouse or sauna, and leave the choice to the consumers.

"Layered cake"

When insulating a “layer cake” bathhouse, the following materials are used:

  • waterproofing film;
  • basalt wool;
  • aluminium foil.

In this case, the foil acts as a material for arranging a vapor barrier for the bathhouse ceiling. Next, a layer of basalt wool is laid. The thickness of the layer depends on several factors: climatic conditions, type of roof and the purpose of the room. The average thickness of the insulation is about 20 cm. If we talk about the ceiling in the sauna, then here the thickness of the insulation layer can be increased. The final layer of this “pie” is waterproofing. It protects the insulation from external climatic factors.

Thermal insulation using mineral wool

One of modern methods Thermal insulation devices for the ceiling of a bathhouse or steam room use mineral wool. This method is suitable for different designs bathhouse roofs both with and without an attic compartment. Moreover, it does not entail very large costs. Before you begin the process of insulating the bath, you need to process everything wooden elements antiseptic agents. Then the work is performed in the following sequence:


In the attic section, a subfloor is made, that is, unedged or used boards are used. This will protect the insulation layer with waterproofing from accidental mechanical damage. You can view the information in more detail in the video.

Traditional methods of insulating a bathhouse ceiling

Baths have existed since ancient times. Our ancestors knew for sure how to insulate a bathhouse from the inside. They used improvised materials, which cost very little in our time, and at the same time they are environmentally friendly. Of course, compared to modern materials, arranging insulation using traditional methods requires more labor.

Sawdust and clay

To insulate the ceiling of a bathhouse that has an attic compartment, you can use materials such as sawdust, clay and sand. The insulation process is arranged in the following order:

Make sure that the sawdust is dry. Therefore, it is better to take them from a carpentry shop, since they use wood with a low moisture content. In the old days, about 3 cm of ash was poured on top of the sawdust layer.

Expanded clay

To insulate a steam room or sauna, it is better to use expanded clay. This type of material has high thermal insulation properties, but has a significant drawback. Expanded clay absorbs moisture very easily. Therefore, when using expanded clay, you should provide a very high-quality vapor barrier on the side of the room. A layer of expanded clay up to 30 cm thick is poured on top of it, and then waterproofing is provided.

Here you can also use earth, or you can use modern materials. If you plan to use the attic, you should install a flooring made of boards to reduce the area of ​​pressure on the ceiling when walking.

Conclusion

As you can see, the process of insulating the ceiling is very important point. The choice of thermal insulation methods is quite wide. Starting from cheap ones and ending with modern expensive ones. What to choose is up to the bathhouse owners to decide.

A bathhouse is a room that requires a special arrangement of the room. It forms the microclimate in the bathhouse, helps to use fuel correctly, and affects the time it takes for the room to warm up. You can insulate a bathhouse in many ways. One of them - proper insulation ceiling. Perhaps not every owner knows how to insulate the ceiling in a bathhouse. To do this correctly, before starting work you need to read the instructions and advice of professionals.

Ceiling in the bathhouse, insulation: the basics of thermal insulation

The roof in a bathhouse can be of several types. The bathhouse may have an attic space, or it may be built without it. A bathhouse with an attic involves a more reliable arrangement of the ceiling, so warm air will escape through it more slowly.

It should be noted that although the presence of protection from the cold in the attic and attic allows you to save heat and slows down the cooling of the bathhouse, it is also necessary to insulate them. You can insulate the ceiling in the bathhouse with your own hands. To do this, you need to study the entire insulation process in order to know all the intricacies of this process.

Specifics of thermal insulation

  • If the bathhouse does not have an attic, aluminum foil, thick cardboard, and wax paper are used for its vapor barrier.
  • If the bathhouse has an attic space, then clay is used to insulate it, and the boards are coated with it on the roof side.

Insulation in a bathhouse or sauna must be done correctly. To do this, you should carefully study the materials that are used for this. Some of them require particularly careful attention.

How to insulate the ceiling in a bathhouse: choice of material

The ceiling in the bathhouse can be insulated different materials. Today, many industrial options make it possible to insulate the ceiling inexpensively and efficiently. It is important that the material is resistant to moisture and evaporation.

In order to know how to properly insulate a ceiling, you need to understand the physical aspects of heat loss.

When choosing a foil vapor barrier, you solve two problems at once - this material does not allow steam to pass through and reflects heat back into the room

Usually heated air leaves the bathhouse through cracks in the ceiling. Heat can also transfer from hot objects in the bath to cold ones. Heat waves can cross homogeneous barriers, which also affects air heating and heat retention.

Materials for ceiling insulation:

  • Using standard polyethylene film;
  • The use of a vapor barrier film with fibers that retain condensation;
  • Use of vapor barrier material with membranes.

A vapor barrier helps control moisture vapor and its settling in the insulating material. Water should not accumulate in it. Thus, it can ruin all the insulation.

Insulation of the ceiling in a bathhouse with a cold roof

Insulating the ceiling in a bathhouse with a cold roof is a very important process. And if the roof is cold, then it must be done several times more carefully.

The bathhouse should not contain any prerequisites for heat leakage. A cold roof must be properly insulated. Step-by-step instruction will help to insulate a bathhouse with a cold roof.

Bath insulation technology:

  • Attach to the ceiling wooden blocks dimensions 5 by 5 cm.
  • Each step will be equal to the size of the insulation material. It will be made in the form of slabs.
  • Insulate the surface with slabs.
  • Place insulation between wooden beams. To do this, you can use mineral wool or foil paper.

Laying should be done by laying the bars across. The foil should be stretched overlapping and attached to the tree with a stapler. The seams must be sealed using adhesive tape. New methods of insulation involve insulation frame bath polystyrene foam.

New technologies for insulating the ceiling in a bathhouse

Modern technologies make it possible to insulate a bathhouse reliably and efficiently. Insulation should consist of several layers. Thus, the room will be protected from cold and moisture.

The choice of modern materials depends on their quality, which has a direct impact on the cost of the material.

The first layer of insulation material serves for thermal and vapor insulation. The second is to protect the first layer from condensation. Insulation materials can be purchased in specialized stores or online.

The best modern insulation:

  • Basalt fiber. It has low thermal conductivity. It is fire retardant, natural material, which completely loses its positive qualities when exposed to moisture.
  • Expanded clay. High-quality material that can retain heat for a long time. However, for it to be effective it is necessary a large number of of this material. Also, expanded clay alone is not enough; it requires additional insulation.

One of the old methods of insulation, which is still used today because of its cheap cost, is clay mixed with sawdust. It takes a long time to prepare. The boards are coated with clay on the outside and inside. It is important to understand that each material has its own characteristics and characteristics. For example, when insulating with mineral wool, you should ensure that there is a hole in the insulation for air to penetrate.

How best to insulate a bathhouse ceiling

There are many options for insulating a bath room. Many ancient methods have survived to this day and are popular. At the same time, insulation can be performed using modern materials. However, their cost will be many times more expensive.

One of the popular and reliable methods of insulation is the thermal insulation of a Russian bath using the Bukharkin and Sosnin method.

This method involves the use of the following materials: wooden beams, drying oil, roofing felt, polyethylene or foil, sand or slag. All actions must be performed sequentially. It is important not to miss a single detail.

Method of insulating the ceiling in a bathhouse:

  • On ceiling beam(20 by 20 cm) hang a ceiling made of tongue-and-groove boards (25 mm each).
  • Cover the boards with two layers of drying oil.
  • On top of the beams you need to lay planks, between which you should not forget to leave a small distance.
  • Spread a layer of roofing felt, polyethylene or foil.
  • Pour 200 mm of sand, you can use slag.

This method is considered quite effective. The second method involves using aspen lining. Clay with sawdust and mineral wool are used as a vapor barrier.

Building a bathhouse is a serious matter. The insulation of the ceiling and walls in the bathhouse must be done very efficiently. It depends on the method of insulation and vapor barrier temperature regime in the bathhouse and its normal functioning. Today, methods of insulating a bathhouse vary in the quantity and quality of materials used. The choice of method depends on the structure of the bathhouse, the quality of its coating, and the presence of an attic or attic.
