Insulate the door jamb of the bath door. How to insulate a bathhouse door yourself? Methods for insulating a steam room door

When frosts drop to a low level, many people who like to take a steam bath go to the bathhouse. And this is right, because this way you can perfectly maintain your body in excellent condition. However, the more you warm up the bath, the more frost will penetrate inside. For this reason, it is extremely important to insulate the door in the bathhouse. This way, you can save heat that will accumulate indoors. This article will discuss exactly how to insulate the door to a bathhouse from the inside and outside.

Why insulate

It is a known fact that after leaving the steam room, the human body is very steamy. For this reason, the room in which a person rests after the steam room must be maintained comfortable temperature. However, if it is cold in the dressing room, then rest there may not be possible. in the best possible way affect health.

One of the common reasons why cold can penetrate into a bathhouse is poorly insulated doors. When sweat runs down your face and your feet are cold, you're not far from catching a cold. It's time to think about insulation front door to the bathhouse. After all, by solving the problems with door insulation, you can completely get rid of drafts. There are several methods for insulating doors in a bathhouse. For example, some people decide to simply hang the blanket on door frame. Others install second doors. But these methods are not always justified. However, it's not all bad. There is a simple and proven method to get rid of drizzle, as well as cold drafts. First, let's look at what an ideal door for a bathhouse should be.

Door selection

The ideal option would be a small narrow door. This will immediately reduce heat loss and also reduce the volume of cold air entering. Ideally, the door to the bathhouse should open to the street. Mainly, this is required by safety precautions. After all, if a visitor suddenly becomes ill, he can open it with a slight movement of his hand. Regarding the choice of material for bath door, then it is best to use hardwood. Not recommended for use coniferous wood, since it is capable of releasing resin during the heating process. When installing doors, it is important to make sure that there are completely no gaps or cracks. Best to install panel doors, as they retain heat better.

Replacing the door frame

After some time, with constant changes in air temperature, as well as high humidity, the door frame may rot. If the installation process door frame and the doors themselves were installed correctly, then replacing it will not be difficult. To do this, you will need to cut the lintel beam, as well as the threshold of the box. But this is the case when the side pillars of the box are not damaged. It is not recommended to saw off the fastening tenons of the timber, since they are responsible for fastening the frame. When old box dismantled, a new one must be made:

1. A groove is cut into the timber along the entire size of the door frame.
2. Next, when all the parts of the door frame are made, you should assemble them into a tenon, and then secure them on the side of the door ledge.
3. The resulting gap between the wall and the frame, which should be no more than 5 mm, should be filled with polyurethane foam.

Double chamber door

Because of large differences air temperature, and also due to high humidity the door will sweat. As a result, the water will freeze as it drains. Accordingly, this will cause the doors to not close tightly. If you install a second door, as mentioned above, you will not be able to completely solve the problem. In fact, it may arise new problem, which will consist in the fact that the gap between these doors will accumulate more moisture. As a result, the doors will very quickly fail, rot and will not retain heat at all. Perfect option- installation of a two-chamber door. You can make it yourself.

To do this, you will need an inch board, as well as fiberboard with insulation. The construction of this building material is capable of smoothing out high temperature contrasts when the temperature difference is very large. All work is done in several steps:

The two-chamber door is ready!

To reduce the flow of cold air into the bathhouse, you can install a thermal curtain. This method is quite effective. First you need to prepare a sealing frame on the bath door block. Then the soft insulation is cut into strips. If the size of the bath door is 1800 by 800 mm, there should be four of these strips: two pieces measuring 10x100 cm and 2 pieces 10x200 cm. Then you need to nail the insulation around the bath door using small nails. Next, take four wooden blocks: two of them measuring 2x184 cm and two measuring 2x80 cm. You should start nailing the bars on top of the insulation and so on around the entire perimeter of the door frame.

Each block should be wrapped with insulation. Excess insulation should be cut off. As a result, you should get a rectangle with insulation.

On next stage work you will need thick fabric, for example, dermantine. It is necessary to cut a fabric/screen from it, measuring 120x200 cm. The fabric should be stitched in such a way that a block can be placed in it. Its size should be 2x2x200 cm. This block should be installed and secured. Next, you should attach the right part to the wall, retreating 10 cm from the platband. The edge is pressed with a special decorative strip. About eight rings should be attached or sewn to the top of the fabric. A fishing line should be stretched over the doorway, which will hold this curtain. The fishing line is secured with two self-tapping screws.

Note! It is best for the screen to slide behind the door. This is due to protection from frosty air. The canvas must fit snugly against the sealing frame. In this case, the door from the inside will not freeze and fog up. And the most important thing is that cold air will not flow into the bathhouse so quickly.

If you didn’t like the above options for combating drafts in a bathhouse, then you will be interested in learning about others, alternative methods insulation of the bath door.

Alternative options

In the market you will find a large number of thermal insulation materials. If you've never had to choose one, you'll need to figure it out. It should immediately be noted that insulation materials, depending on the manufacturing technology and the original raw materials, can differ into the following types:

• foamed polyethylene foam,
• staple fiberglass,
• basalt insulation,
• expanded polystyrene,
• extruded polystyrene foam.

In each individual case, the choice of insulation will be individual. The choice should be made taking into account the flammability of the material. Thus, insulation made of foamed polyethylene foam can be used at temperatures from -60° C to +100° C.

Extruded polystyrene foam, as well as simple polystyrene foam, in turn, allow other temperature regime operation, namely from -50° C to +75° C. Each of the insulation materials will differ in this indicator. It is also necessary to take into account another indicator, no less important - vapor permeability. Thus, polyethylene foam and expanded polystyrene foam will form a “greenhouse” effect. The steam that will come out of the bath will not be able to penetrate through these materials. If the door in the bathhouse is insulated with these materials, the wood can quickly become damp, and accordingly, very soon it will have to be replaced with a new one.

The method of insulating a bath door will be directly influenced by its design. For example, insulation can be placed inside the door. Another option is to lay the insulation over the door and secure it with nails or screws. In addition, there is a third method of insulating the door itself. The frame for the door is pre-made from a block. Insulation is placed in this form, and the structure is closed on top fiberboard sheet or plywood. Now let's look at the last option for insulating a bath door.

To begin, take a block 20 mm thick. Use it to make a frame for the door. Nail the finished frame to the door itself.

Note! The outer border of this frame will be different from the border of the door. This distance should be 15 mm. Accordingly, insulation is nailed along the entire perimeter of the frame using aluminum nails. It should protrude by this 15 mm. Afterwards, the frame can be filled with one or another insulation.

When the insulation is laid, it should be covered with a sheet of plywood or other material that is at hand. The size of this canvas should be identical to the size of the manufactured frame made of beams. This entire structure is nailed down with nails or wood screws. Based on the results of this work, you will get the following: when the doors are closed, the insulation will rest against door block, due to which it will bend slightly outward, which will prevent cold air from entering the bathhouse. This insulation method is simple, but it has a number of positive features. The most important thing is that it will completely prevent the appearance of drizzle on the doors on both sides.

If you are unable to build such a structure, then you can use the old proven method. As thermal insulation material you can use an old cotton blanket. It should be cut into equal strips lengthwise. Afterwards, tightly stuff the door leaf around the entire perimeter. In this case, part of the strip should cover the door hatch. Although this method will not save you from drizzle, such insulation will last for some time and protect the bathhouse from cold air.

The choice is yours!

So, we looked at the most different methods insulation of the bath door. In this case, you can completely replace the doorway, make thermal curtain, and also use more simple methods on insulation. Each of these options is good in its own way, so it’s up to you to choose. In each case, one or another insulation method will be effective. But most importantly, remember, under any circumstances, the door must fit tightly to the door frame!

Preface. In Russia they can be strong winter frosts, but it is in winter that our compatriots want to warm up and take a steam bath in a bathhouse. When heating, the more you heat the bathhouse, the more forcefully the cold will penetrate into the steam room of the bathhouse. Every owner of such a building should take up insulation of the door in the steam room. Let's consider the technology of carrying out similar works and we will show video instructions at the end of the article.

Is it necessary to insulate the steam room door in a bathhouse?

Is it worth insulating the door in the bathhouse? If the steam room door is not insulated, the floor in the bathhouse will be cold and your feet will freeze. You should keep the steam room warm and get rid of drafts. Everyone solves this issue differently: some try to insulate the dressing room, others prefer to insulate exclusively the steam room. But in this matter it is worth approaching the problem comprehensively.

The fact is that due to temperature changes on the inner surface door leaf, frost appears in places where the door leaf and slopes touch. The door swells due to humidity, and then it will not be possible to open the steam room door without using a specialized tool. It is necessary not only to insulate the doors, but also to insulate the floor in the bathhouse and in the dressing room; all these measures will protect the room from the penetration of cold air.

How to insulate a bathhouse door with your own hands

Today, manufacturers offer a wide range of thermal insulation products on the market modern insulation materials for various purposes. Depending on the raw materials and manufacturing technology, the following types of thermal insulation are distinguished in construction: basalt insulation, expanded polystyrene and extruded polystyrene foam, polyethylene foam, etc. But what is the best way to insulate a steam room door in a bathhouse yourself?

When choosing insulation, you should pay attention to the following points. First important characteristic– this is the flammability of the material. Penofol, isolon and other insulation materials made from foamed polyethylene should be used at temperatures up to +100C, expanded polystyrene and polystyrene foam up to +75 degrees Celsius. Basalt insulation materials (Rockwool, URSA, Isorok, etc.) are made from rocks, therefore open flame they are not afraid.

Next, you should compare insulation materials by thermal conductivity and pay attention to vapor permeability. Expanded polystyrene and expanded polyethylene foam do not allow steam to pass through and do not absorb moisture, so even in a humid environment these materials do not lose their characteristics. Basalt thermal insulation without high-quality waterproofing can absorb moisture, thereby losing its thermal insulation properties.

Do-it-yourself insulation of a bathhouse door

Before insulation, you should know that it is better to make the door in the steam room low and narrow - this will reduce heat loss and prevent the penetration of cold air. The door must open outward according to safety regulations. It is better to make the door leaf from hardwood, since conifers Wood releases resin when the resin is heated. Doors must fit tightly to avoid any gaps.

Replacement and thermal insulation of the door frame

There are two technologies for manufacturing door frames. According to the first option, a groove is cut in the timber using a cutter; the size of the groove should be equal to the width of the door leaf. After making the parts, you need to assemble the box and secure it with self-tapping screws. The space between the door frame bars and the bathhouse frame should be as small as possible. The gap should be insulated with moss, tow or foam.

According to the second option, the door frame is made without the use of timber. For the box, take a board of 50 millimeters, leave a quarter of the board for the door ledge and assemble the entire structure. Self-tapping screws should be used to secure the door frame in the opening; the connection of the parts in this case will be much tighter. From outside and inside slopes, all that remains is to attach the paneling.

Insulating the steam room door with your own hands

The technology for insulating doors varies depending on the design of the door leaf. The first method of thermal insulation is that the insulation is placed in the internal cavity. The second option (covering the door with dermantine) - the insulation is attached to the canvas, and it is closed on top decorative coating. The third method is to make a frame of bars on the door, lay insulation between them and cover the top with plywood or OSB.

We will not consider how to insulate a bathhouse door with dermantin. Let us choose for analysis an insulation technology with a frame made of bars. To do this, a frame made of bars with a cross-section equal to the thickness of the insulation boards is attached to the bath door with self-tapping screws. Insulation boards are tightly laid between the frame bars. When using expanded polystyrene for thermal insulation of a steam room from the inside, all cracks and joints should be additionally foamed.

Next, a sheet is attached to the bars with insulation OSB plywood to protect thermal insulation from mechanical damage. Placing insulation inside this structure will protect the steam room door from frost, while the fabric will remain dry. The same technology is also used when insulating the door in the dressing room with your own hands, in order to prevent cold air from entering this room.

Making an insulated door for a bathhouse

As a result of high humidity in the steam room and large temperature differences, an ordinary door, even a high-quality insulated one, will get wet. Condensation will flow down the canvas and freeze, making it difficult to close or open the door. When making an insulated door for a dressing room and steam room this problem is being decided. This door can be made on your own from bars, OSB sheets and any foil insulation.

To make a door, you will need a beam with a cross-section equal to the thickness of the thermal insulation slabs, from which the frame of the door leaf is made the right size. On one side the frame is sheathed with moisture-resistant OSB boards. Next in door frame thermal insulation is laid, filling all voids, and the entire structure is sheathed from the second OSB sides or fiberboard. Attach the awnings and place the door in the opening.

In order to create and maintain the required temperature in the bathhouse, you need to take the issue of insulating the room very seriously. Ceilings and walls, windows and doors, large and small cracks - when it comes to insulating a bathhouse, nothing is secondary.

But door insulation in a bathhouse is perhaps the simplest and fastest of all insulation processes. For the most part, the total period of insulation work takes no more than an hour.

Door insulation. Which is better?

Before insulating the door to the bathhouse, need to take care of high-quality insulation . Some very thrifty owners, they put into use pieces of old artificial fur coats, synthetic padding from deteriorating winter clothes, who have served their purpose cotton blankets. And they are right in their own way about being frugal.

True, at the same time It is advisable not to forget about fire safety. Old rags burn quickly, and a bathhouse is a room with a high temperature. And even if the steam room, as it should be, is oversaturated with wet steam, this cannot always save the situation in case of fire.

So, the first requirement for door bath insulation: maximum fire resistance.

Second: vapor permeability.

The main trouble greenhouse effect The problem is that due to dampness the door rots and becomes deformed, forcing the owner to do nothing but insulate and repair it from year to year.

In addition, drops of condensation hang on the surface and constantly flow from the door, forming puddles under your feet.

The formation of condensation and drips become the main reasons NOT to USE such convenient and cheap materials as polystyrene foam as door insulation.

Usually a bath door insulated with proven materials: felt, cotton wool (it is better to take ecowool treated with fire-resistant mixtures).

If there is such an urgent need to keep up with the times, then use polyethylene foam, always with a foil layer. Lightweight material, resistant to cold, non-flammable, and the foil is able to return heat indoors.

So, let's summarize. Ideal insulation for a bath door there will be material that:

• is lightweight and does not deform the door with its weight;
• vapor permeable, which will prevent the formation of condensation;
• does not absorb moisture;
• not very heavy.

Ways to insulate a bathhouse door

After you decide on the insulation, it’s time to choose how to insulate the door in the bathhouse - that is, the insulation method itself.

Today there are two main door-insulation schemes::

• internal, when the insulation is placed in the door chamber;
• external, when the insulation is attached to the surface of the door using glue or nails.

Frame

One of the simplest and least labor-intensive ways insulation of the bath door.

1. Nail a frame of 15-20 mm bars onto the door surface. Please note that the outer border of the frame should be at a distance of 15 mm from the border of the canvas.
2. Fold the insulation in half and nail it onto the frame with small nails.
3. You can also insert a sheet of hardboard into the void formed between the insulation and the surface of the door.

EFFECT: when closing the door, the insulation will rest against the door block, bend slightly outward and completely block the access of cold air to the room.

The whole process will take you 1.5 hours.

Energoflex

And here even more quick way insulation of bath door. For it you will need a well-known pipe insulation - Energoflex.

1. Press the insulation along the edge of the door, tightly, but taking into account that after insulation the door opens and closes without problems.
2. Attach the energy flex to the surface using construction stapler.
3. Screw onto the structure from above metal slats.

EFFECT: increase in heat retention by 30-35%, plus convenience: the insulation fits perfectly onto the surface and takes on its shape, including all irregularities. In addition, the energy flex can be easily repaired in case of damage.

The time required for this insulation process is 20-40 minutes.

Thermal curtain

The simplest way to insulate. Suitable for those who have not yet figured out how to insulate the door to the bathhouse.

A curtain can save you from moderate cold, so it would be logical to help insulate the door in some other way.

1. Find a durable but not bulky material (best of all, a piece of dermontin), cut it out and cut a curtain that matches the size of the door. Make the curtain blank slightly wider than the doorway.
2. Sew the future curtain at the top and bottom, taking into account the fastening system.
3. Hang a curtain over the door. You can attach it in different ways:

• rings on the pipe;
• valve onto the pipe (in this case, when stitching, you will need to compare the size of the pipe and the size of the valve firmware);
• clothespins.

Second door

Some of the bath attendants the perfect way consider installing a second door. This method of insulation has a right to exist, it quite effective. But when installing interior door no one exempts you from insulating first.

To establish additional door You need either a jamb that would be designed to hold two doors, or a plan for how to fix another structure to the existing one.

If the door jamb is not designed for two doors, it is necessary to install an additional one.

EFFECT: in this case, the air cushion formed between the doors will act as insulation.

Replacing the door frame

Often, with a well-insulated door, the cold still manages to penetrate into the room and then a temperature paradox is observed in the bathhouse: when it is hot, when sweat drips from the face, the legs do not heat up.

This is not normal for a steam room, because instead of the expected seven pounds of health, you can easily “bring” a cold from the bathhouse.

A rotted threshold or rotted corners of a door frame can let cold into the bathhouse.

Replace door frame doing it yourself is quite problematic. In addition, such repairs should be undertaken exclusively in the warm season.

And here partial renovation - everyone can do it. This is another one affordable way for those who don’t ask how to insulate a bathhouse door, but go ahead and do it.

1. Rotten beams must be sawed. Remove them piece by piece from general design it will be much easier and more convenient.
2. When sawing, try not to touch the fastening tenons.
3. Cut out the new door frame elements according to the dimensions.
4. Insert them in place of the rotten ones.

Such a replacement absolutely cannot affect the evenness and strength of the door frame and walls.

EFFECT: you will return the missing 15-20% of heat to the room.

Time spent – ​​no more than 8 hours.

Bath door standard

Which door to the bathhouse is the most correct, the most heat-saving and the most comfortable? There is one!

The correct (reference) bath door should be:

• narrow and not very tall. Such a door, when opened, reduces the exit warm air outside;
• open outwards so that, if necessary, you can very quickly let a little refreshing coolness into the steam room;
• made from deciduous trees so that the heat does not release resin onto the surface;
• perfectly adjusted to the dimensions of the door frame, so that there are no gaps between them.

Building a sauna with your own hands is not that difficult. But it is important to take into account the recommendations of experts in order to avoid the most common mistakes and errors.

As practice shows, one of the most common mistakes– an incorrectly fitted, uninsulated door that allows cold air and drafts to pass through. Therefore, it is important to know how to insulate a bathhouse door quickly and effectively.

Why insulate the door?

As a rule, between the steam room and outside door there is a dressing room. If the structure is not insulated enough, cold air will definitely penetrate into the dressing room and steam room, distributing in the lower part of the room.

One more point - from the inside to the surface external door Condensation will settle due to the temperature difference, which will then turn into frost. Therefore, it is better to take care of insulation in advance.

Which material to choose

The modern market offers many types of thermal insulation materials:

• mineral basalt wool;
• staple fiberglass;
• hardboard;
• expanded polystyrene, etc.

Which one is better to choose for a bath? One of the main criteria is fire safety. The insulation must be highly resistant to fire and not emit harmful substances when heated.

Vapor permeability also matters. We must not forget that the door, like the bathhouse itself, is made of wood, and this is a natural, “breathable” material. If air access is blocked on at least one side, the wood will become damp and rot, and this will significantly shorten its service life. Therefore, it is extremely undesirable to use adhesive-based polystyrene foam boards for baths.

It is also necessary to pay attention to the weight of the material. The insulating structure should not exert significant load, otherwise the door leaf may warp.

One of best options Based on the above requirements, there will be foil-coated polyethylene foam. It is a lightweight, non-flammable material that can reflect heat back.

Thermal insulation methods

There are several ways to go to the bathhouse:

• insulation of the surface of the canvas;
• laying insulation in the internal cavity of the structure;
• installation of the second door;
• use of thermal curtains.

Insulation of the canvas

The fastest and easiest way to install door insulation is insulation on the frame.

First they prepare wooden blocks 15-20 mm thick. The size is calculated based on the height and width of the door.

Then on the door leaf, from the side edges towards the center, 15 mm are measured on all sides - at this distance the bars in the form of a frame will be nailed around the perimeter. To do this, use a hammer and aluminum nails.

Installation of thermal insulation material

Insulation is nailed around the perimeter of the frame - it is better to fold it in half. It is cut in such a way that it completely covers the door frame, leaving a free edge of at least 15 mm on all sides.

The area inside the slats can also be covered with a layer of thermal insulation material.

Sheathing

The final stage is the installation of sheets of plywood or fiberboard.

As a result, when closing the door to the bathhouse, the insulation will fit tightly to the door frame, eliminating the slightest chance of cold air entering the room and getting the wood wet.

Thermal insulation with energyflex

Another very simple way to make a door warm and airtight is to use energyflex, a heat insulator for pipes.

The material is cut in the same way as for insulation on the frame, pressed along the edge of the door and fixed with a construction stapler. To ensure reliable fastening, metal slats are installed on top of the insulation - thanks to this measure, even with intensive use, the insulation strips will not fall off.

Finally, you need to tightly close and open the doors several times - the insulation will spring back and take the desired shape.

Application of Thermal Insulation Curtain

And probably the most easy way Bath door insulation is a thermal curtain attached to the frame. Usually this method used as an additional one, having previously insulated the door structure itself.

Cutting the material

A canvas is made from dermantin or tarpaulin that will serve as a heat-insulating screen. The dimensions are calculated as follows: the length and width of the door plus 20 centimeters for fixation.

The screen should completely cover the door and be securely attached to the walls above and on the sides of it. Several eyelet rings are sewn onto the top edge of the curtain.

Installing curtains

A “pocket” is made in one of the sides, into which you need to insert a block 20 mm thick. A cornice should be built above the door from a metal rod or wooden block.

The material is hung on the cornice. The free side edge of the resulting screen is attached to one side of the door using self-tapping screws with a distance of approximately 10 cm from the casing.

Hooks are attached to the opposite wall. Rings are sewn on the free edge of the screen, which are put on the installed hooks when the screen needs to be closed. Thermal curtain ready.

After all the measures, you get an insulated frame on the door frame, which ensures that the door is tightly closed, and a heat-insulating curtain, which, when not in use, is located on the side of the door in a shifted form, and, as necessary, moves apart and is fixed, pulled on the opposite side with hooks.

If you need to quickly insulate a door with your own hands, it is permissible to use sheepskin, felt or a woolen blanket.

High-quality, professional insulation of the dressing room will be ensured by the installation of a massive two-chamber door with internal insulation.

To take a steam bath from the heart you need heat And good room without drafts. This result can be achieved by properly insulating all surfaces. Door and window openings are no exception. Some owners don't take the importance of door sealing seriously. The door leaf, no matter how dense and high-quality it is, still has gaps between the end and the jamb of the frame.

In a full-fledged bathhouse it should be hot everywhere, just a little less below. There is no need to be afraid that insulating a bathhouse door will take a lot of time and money. Actually this is not true. But let's talk about everything in order.

Which material to choose

Today there are many insulation materials on sale, but not all are suitable for the steam room climate. The temperature in this room is high and excess humidity. Taking these criteria into account, the product must be:

• fireproof;
• does not release toxic substances when heated;
• waterproof;
• steam-conducting.

All this is necessary for the safety of users, the health of those taking the bath and the durability of the door leaf.
Even if the product absorbs moisture, such as:

• felt;
• seaweed;
• ecowool.

it should give it away just as quickly when ventilated. To achieve this, ventilation gaps are installed to promote natural evaporation.

To ensure the safety of moisture-absorbing materials, a water barrier is created. It is better to use foil for the steam room door. It reduces heat loss due to the reflective effect. At the same time, the material reliably protects subsequent layers.

In most cases, foamed polyethylene with a foil layer is used for insulation from the inside. To prevent the wood from getting wet, it is mounted on it by gluing. The glue must be resistant to high temperatures.

If the door is lined on the outside, almost any material will do, be it polystyrene foam or mineral wool. The main thing is to do it from the inside good waterproofing. Someone gets out of the situation by upholstering the outer part:

• old coat;
• carpet;
• leatherette and other unnecessary but suitable things.

The cost savings with this approach are not justified. After all, fungi and mold develop in such insulation. As a result, the entire room may become contaminated with dangerous bacteria.

It is better to use an inexpensive one, but reliable foam. He:

• easy to install;
• has good insulating properties;
• accessible;
• common;
• It has big choice thickness

Methods for insulating doors

Before insulating a bathhouse door, you should consider several methods and choose the most appropriate one. At the moment, there are two options for insulating doors in bathhouses:

To do this, you need to cut the felt to the required length and width. For example, a doorway is 80 * 50 centimeters. It is necessary to cut two strips of 80 cm in length and two of 48 cm in width (subtract 1 cm from each side of the vertically nailed felt). It must be taken into account that these patchwork strips will be folded in half lengthwise along the entire length, it is for this reason that the width of all four strips must be taken into account in advance.

The cut felt is folded in half and placed around the entire perimeter of the door frame. Then you need to cut the strips that will press the felt tightly. Their size should no longer be 80 by 48 centimeters, but smaller by the thickness of the installed insulation. The bars, cut to size, are placed on the insulation and screwed with self-tapping screws, tightening and leveling the felt.

It is important to understand that the felt should protrude forward and flatten when in contact with the door, blocking access to drafts. And the pressure strips should be installed so as to prevent contact with the canvas. They are attached at a distance of 1-1.5 cm from the closed door leaf. The entire process can take from 30 to 50 minutes.

To work you will need:

• tape measure and chalk;
• a good knife or scissors;
• hammer and nails or screws and a screwdriver.

Insulation of the door leaf

This option is applicable if wooden door It dries out and gaps form between the boards. Before insulating the door in the bathhouse with felt, the fabric is cleaned of possible areas of rotting and peeling. After this, the seams between the boards are filled with insulation, previously cut into thin strips. Instead of felt, the following is used:

• tow.

The insulation is fixed to the canvas using:

• sealant;
• putties;
• liquid wood.

After filling the gaps, you can further protect the door from the outside:

• expanded polystyrene;
• basalt wool;
• polyurethane foam

For external insulation You can use Energoflex. A similar material is used for pipe insulation. The finished size of the cut insulation is placed on the door block and fixed with a construction stapler from top to bottom. Metal nails are also used for fastening.

After the tube is secured with staples, it is recommended to screw wooden or metal slats along the edges of the door. This work can be completed in 15-30 minutes.

Insulating a bathhouse door with felt follows the same scenario, only if the felt is thick you will have to use nails instead of a stapler. The staples will not be able to penetrate such high-strength material. The big advantage of this product is its durability and environmental friendliness.

Felt is not used inside. The material ignites even from a small spark. When burned, it smolders, while emitting a lot of smoke. This specificity will serve as a signal to the owners, helping them react in time to a fire.

Under exterior finishing a frame is mounted on top of the insulation. It is created around the perimeter of the door leaf. The insulation is placed in the space between the slats. Therefore, the height of the frame slats should be equal to the thickness of the insulation.

The bottom gap can be removed by stuffing a felt skirt at the bottom of the door. To do this, cut out a piece of material 4 cm wider than the gap itself. 2 cm will be used for fastening to the canvas. The remaining two will spread along the floor to prevent blowing.

In this case, you will not have to create a threshold. After all additional design on the floor will interfere with cleaning. In addition, you can get caught on it and get injured.

Safety curtain

If it is not possible to do the above options, then you can use another method to cut off cold air. A piece 4 cm wider than the doorway is cut out of canvas or leatherette. Above the door, with outside a curtain is attached or a wire is pulled.

Rings are sewn to the top of the curtain. The product is hung and a fishing line is sewn to its edge. When the door is closed, the line stretches, covering the opening.
