We choose suitable materials for thermal insulation and give step-by-step instructions for insulation of the input door.
Before heating the wooden door, it is necessary to get rid of other cold sources. In order to use the work done, comprehensive measures are required. The cold penetrates through the slots together with drafts. In a private house, you should pay attention to the floor and the ceiling, as well as low-quality window and balcony windows. Check all the angles and places where the prefabricated elements are connected. And only after all sources of the cold are eliminated, it makes sense to warm the front door.

By what channels the cold penetrates through the door
The array has a property of changing its dimensions and shape under the influence of moisture and temperature. Fibers absorb pairs and condensate drops. As a result, the internal space becomes greater. At negative temperatures, water turns into ice and increases in volume. The stresses caused by its deformation are capable not only to change the direction of the fiber, but also damage it. As a result, empties arise, by which the air from the street enters the room.
- The slots between the box and walls of the opening - they are formed due to the fact that in the old houses the details are gradually breathable. Communications are violated. With a significant deformation, the channels are preserved even after the swelling caused by the oversaturation of moisture. The space filled with the mounting foam is closed with platbands. If you install them loosely, the porous structure of the mounting foam will begin to collapse, losing its insulating properties. To solve the problem, it is necessary to disassemble the design, if necessary, change or repair the parts, put on the mounting foam, close with vaporizolation tape and hermetic plates.
- Empties between the box and the canvas - they appear as a result of raising the boards and change their shape. The reason is the long exploitation, the low quality of the array and error made during installation. Some breeds are able to serve several decades. Such properties have sea oaks, exotic dark rocks. Spruce and pine Even after special processing, quickly lose the form. One of the reasons for the occurrence of emptiness is incorrect actions during operation. Wake-up sash sometimes you have to trim so that it goes into the opening. After shrinkage, it decreases in the amount, and the free space on the site of the remote part becomes the source of drafts.
- The slots between the boards, of which are assembled by the canvas, become the bridges of the cold even with a good finish. Before you insulate the wooden door in a private house, you need to get rid of them. The filler under the upholstery may not correspond to the required quality. In addition, products have a limited service life. After the expiration date, they need to be changed to new ones.
Suitable insulation materials
Their choice is determined by the requirements that are presented to the bandwidth. It depends on the thickness of the layer. The more massive design, the more harder, but the better it works. For the cottage, lightweight structures are suitable, for a cottage with durable walls and reinforced openings, a multilayer insulating cake is used, which has a lot of weight. In both cases, the external finish should look beautiful.Products with fibrous and porous internal structure are used as a filler.
Mineral wool
It is fibers of molten rocks, glass and blast furnace slag. They are not afraid of moisture, do not burn, do not distinguish harmful substances. We are produced in the form of plates or an amorphous mass, which is evenly filled with the trim. When wetting, it loses its volume and begins to carry out cold, so it must be put in the cells of the crates protected from moisture. Mineral wool has good thermal indicators. One of its differences is that the coating will not be able to spoil rodents.
Styrofoam
Polyfoam is interconnected bubbles with polymer thin walls. Released in plates. It has excellent technical characteristics, but is dangerous to health. Even at room temperature, the surface sends toxic substances. Polyfoam refers to the class of fire hazardous materials. After impregnation with antipirens, he cannot burn independently, but under the influence of open flame burns and melts. To create an effective layer, a smaller thickness will be required than the Minvati.
Polyurene Foolder
Polyurethane foam (PPU) is sprayed on the surface of the canopy. It fills all empties. To secure the material, it is not necessary to put the crate. For installation, you do not need fasteners in contact with the cooled surface and easily conductive temperatures inside. PPU does not support burning. Under the influence of open flame, it melts, highlighting carbon monoxide and carbon dioxide.
Polyethylene foamed
Foamed polyethylene differs from its analogues in that it does not miss moisture. Corolon can be brought as an example. It is made in rolls and has a thickness of 1-1.5 cm. With such a thickness, it does not provide the necessary protection and is used as an addition to the main layer.
Seals for slots
In order for the cold to penetrate the slot between the sash and the box, this space is cured with seals. They are fixed on the inside of the opening.
- The foam band - with the back of the side has a sticky base. It works efficiently, but wears over a few months.
- Silicone gasket - provides a more dense adjoining. Briefly, but serves longer than Faudo.
- Tubular rubber seal - does not absorb moisture, racks to mechanical loads and is able to serve several years without losing its properties.
- A sticky tape based on polyurethane - according to technical specifications does not differ from rubber.
- Thermoplastic products - have the highest resistance to mechanical loads, but are complex.
Step-by-step instruction on the insulation of the inlet wooden door for the winter
Before heating the entrance wooden door, it is necessary to collect everything you need to not waste time when you find the missing parts and tools.Tools for finishing
- Rule, roulette and marker.
- A knife with a long sharp blade that allows you to make a smooth section of a mineral wool or foam plate.
- Saw on wood.
- Hammer and nails.
- Screwdriver or screwdriver.
- Building stapler and set of brackets.
- Pliers and nail holder.
The skin is better to use leatherette. It does not wet, does not break, keeps the form well. It is easy to care for him. Pollution is removed with a damp cloth.
Preparation of the web
It includes several stages.
- The canvas are removed from the loops and eliminate the skews of the opening. Damaged box parts and sash are replaced with new or repaired.
- Put a new seal.
- Change accessories if the old thing is worn out.
- With a large mass of insulating cake, a third additional loop between two mains is mounted.
- Clean the surface and dried with a radiator or a construction hairdryer. In order not to have any distortion, you should choose a soft drying mode.
- Raw parts are coated with antiseptic, antipirens and varnish, preventing moisture in the array. You need to handle not only the surface, but also the openings under the accessories.
Laying insulating materials
The sash is a solid canvas or frame from a bar and boards. Empty fill in full. Even a small gap will lead to a noticeable heat loss. Plates should fit tightly to the inner sides of the frame, and their curvature is not allowed. The size of the panels should be more than several millimeters. Products made of mineral wool having a protective shell, cutting undesirable - otherwise they will lose form.
The main layer should be located on the outside facing the street. In this case, couples in the material will turn into condensate in insulating layers. The temperature mark at which its condensation occurs, is called a dew point. If you lie on the inner side, the condensate falling zone will shift with it. This will lead to an increase in the inner humidity, the appearance of the smell of dampness and the formation of mold in the cake. The fibrous structure will lose its effectiveness, since empties will fill water drops, perfectly conductive temperatures. The inner layer is used only as an addition to external.
Unlike foam plastic, the mineral wool and PPU have open empties that need to be closed with moisture protection layer. This may be plastic film, isolon or membrane, passing steam from the inside. It is located on both sides of the stove, as the condensate penetrates from the array.
The insulating coating is cut by the standards taken from the canvas. Its area should exceed the sash area by 10 cm on each side. Abundant is cut out with the same allowance. This stock is needed to convert the edges by forming sealing rollers around the perimeter.
The panels on the plane are fixed with a stapler, special nails with wide hats, or plant on glue. There should be no cracks. The remaining emptiness fill the mounting foam. The edges are not stitched - otherwise they will be difficult to make the break.
Top laying upholstery and smoothed it. The coating is nailed with wide decorative hats, moving from the middle. The edges are tested under the plates and sewn with nails. As decor, the area is tightened with wire, forming on it the same rhinestones from the discovery parts. Instead, strips of leatherette, rolled up with a tube and stuffed with foam rubber, are often used.
The top can be closed with a metal decorative sheet or a veneered MDF slab. In this case, the weight of the sash will increase, and it will have to put additional loops. The sheet is mounted on a framed cream from a bar whose cells are filled with an insulator.
Installation of sealing tape
Its thickness is selected by the magnitude of the gap between the canvas and the box. The thin layer will not provide protection from cold, too thick will interfere with the sash closed. In addition, it will quickly erase and deform under pressure.
The strips are cut into four parts corresponding to the length of each side of the opening. When docking, they should fit tightly to each other, so each fragment is made with a reserve of several millimeters. Products are attached to glue, brackets or nails in the groove on the perimeter of the box. The back side may have a sticky surface.
Instead of the finished sealer, the roller from the remaining leatherette is often stitched, tightly stuffed with string of soft insulating materials - mineral wool or foam rubber. In this case, before heating the inlet wooden door with their own hands, you need to calculate the consumption of materials.
