How to warm front door of the apartment (metal, wood) with his own hands

Through poorly insulated front door it takes about the same amount of heat as through a hole with a diameter of 20 cm. Eliminate heat loss and also reduce penetration of odors and noise in several ways. The most simple cheap and available to all. Seriously insulate the door to the apartment and the adjacent section of the wall with his hands more difficult, but also possible with clear instructions.

Features thermal insulation front door of the apartment

Methods and materials are selected depending on the causes of poor insulation characteristics and constructional features of the opening. Building codes should be considered in order to avoid exceeding the maximum permissible weight. Wooden door will not stand certain options, such as the installation of metal ribs for fastening thick insulation. In the metal they are originally. The major differences in the ways of warming due to the specific occasion.

Depreciation seals

The service life of shims between the door frame and sash low. Especially if the type of material or felt batt encountered in the old session. Rubber and plastic, too worn out. How to identify:

• visually inspect the seals, maybe they Easterly or detached;
• if you run your hand along the perimeter of the door through palpable.

In this case, it is recommended to completely replace the gaskets with new ones. These come in the form of adhesive tape or attached to nails, screws, glue. Mortise option is suitable for wooden doors - when the perimeter and cut a small groove to insert the rubber seals. This method allows them to easily change later.

Poorly insulated flap

Doors in older homes hit, as a rule, a layer of foam. This isolation will soon start leaking from temperature and humidity. Metal shutters are now insulated with modern resistant materials, which do not lose their insulating properties for decades. However, they have a life. To determine the time when to warm flap easily - surface of the door becomes ice at low temperature.

To insulate the door panel with your hands, you need to remove the cover, attach new thermal insulation and to surface again. Wooden door repair is recommended on both sides. At this point, it is advisable to also replace the worn upholstery. Construction of metal doors normally allows itself to remove only the internal panel - made of wood or MDF.

The gaps between the wall and a box

Gap around the doorway carefully insulated with foam. Its service life is dependent on climatic conditions, the composition density. On average, from 5 to 15 years, then the foam begins to crumble. If another insulation when installing the door has not been used, then the perimeter begins to blow. According to drafts when quality seals and warm enough leaf can guess that it is necessary to repair the opening.

Options for how to insulate the front door of the apartment with such a lack of:

• to remove a layer of plaster around the box inside and outside, to remove the old foam, again zapenit and plaster;
• cut inside the grooves around the door and also foaming, lay insulation with long life - penoplex, mineral wool;
• nailed to a wooden casement outside rollers - leatherette strip with the tubular foamed polyethylene inside, which will close the wall a few centimeters.

As a result of subsidence at home or door under its own weight and the box may become distorted. It's easy to find it by opening the flap by 45 ° - skewed will spontaneously closed or opened, and not stand still. In this case, it is recommended to tighten or replace the hinges. If this does not work, it is a box of alignment. Then the cracks around her warmed by the above methods.

How to choose the material for insulation doors

Sealers for the entrance doors are made of rubber, foam rubber, synthetic felt, plastic. Advantageously, a flexible cord, which is sold in running meters. For the purpose of warming their hands is recommended to buy a self-adhesive version. Foam and felt comfortable to work with such a leaf seal closes easily. But their resistance to the external environment and the wear resistance is much less than other materials.

The most popular soft rectangular or tubular rubber seals, as they have a service life of at least 5 - 7 years, not only protect from heat loss, but also by odors, smoke, noise. The most durable and resistant to temperature profile of a thermoplastic - single, double or triple.

It is important not to be mistaken with a choice of a filler for insulation flap and space around the box, because it is difficult to change often, unlike seals. The lower the thermal conductivity, the better a material retains heat. For wooden doors fit most thin and lightweight fillers, for metal - any. With a soft, flexible insulation is easier to work, it covers the surface with a margin shrinks as needed. Solid is not hard to cut, but to choose the thickness and dimensions of the individual elements stand have high precision.

Overview of heaters used for the front door:

insulating material	the thermal conductivity, W / m • K	pros	Minuses	Life time
Foam (polyurethane foam) 80 rub. / sheet	0,025-0,035	- Thin - Light - Easy to install	- bibulous - Low iznosostoykost- Operation of -15 ° C- Flammability	to 10 years
Mineral wool from 50 rubles. / Range	0,036-0,055	- Soundproofing - flame-imbued	- Water absorption	to 50 years
Foamed polyethylene foil from 60 rubles. / m2	0,039	- Thin - Sometimes a self-adhesive - Noise - Waterproofing - Easy to install	- Sold in rolls, rarely cut running meters	over 50 years
The foam (foamed polystyrene) from 40 rubles. / m2	0,033-0,05	- Light - insensitive to humidity	- freeze on the joints - The width of 5 cm - Combustible	to 20 years
Penoplex (XPS) 100 p / plate	0,03	- insensitive to humidity - Soundproofing - Waterproofing	- High fire safety	to 50 years

Important! Glass wool is harmless enough, fine glass dust may get into the air and light, as the lining is not always sealed.

As the front door trim use eco-leather, wood panels or MDF - mostly the stuff that was on it before. But you can completely change the design by selecting a different coating. List of components and tools that will be needed during the reconstruction:

• fasteners - staples, nails, screws or glue;
• appliances - staple gun, angle grinder to cut grooves;
• solutions - foam, acetone to a surface treatment before applying parts.

In addition, the required finishing materials for the walls around the box, plastic plugs to close the nail heads and technical holes.

Procedure for insulation doors with their hands

Methods and complexity of the restoration depends on the type of door. It is necessary to calculate the forces before repairing heavy iron construction - weight European standard models with thick double steel and a covering made of wood comes to 100 kg. Chinese single sheet and wood coated with - from 25 to 50 kg.

Consider how fully insulated metal entrance door in an apartment, including canvas, gaskets and surrounding area:

1. Groove cut in the wall around the inside perimeter of the depth and width of 2 - 4 cm.
2. Remove old foam around the box, the gap is filled with fresh.
3. After drying, the foam is cut, inserted into the recess of the selected insulation strips.
4. Plastered walls, decorate with plastic or wooden transoms, wallpaper, paint.
5. Dismantle the inner panel flap, remove the old insulation.
6. New insulation cut to the size of the lattice ribs, simply insert hard, soft sometimes put on the glue to reduce rainfall.
7. cladding panels are fixed back, preferably with new screws, hang fittings.
8. The frame and the seal web is glued strips.

If you want to insulate the perimeter of the first run to the wall, then with the door surface. This procedure helps to avoid damage to the already restored svorki.

Important! Joints solid insulation sheet to be sealed with foam to avoid formation of a cold spot at their corridors.

Installation of insulation on the wooden door will be different. The design, fitted by leatherette, set only soft insulation:

1. Skin removed from both sides.
2. On a wooden board sheets nailed insulation inside and outside, the distance between the nails 10 - 15 cm.
3. Insulation tailor with a margin of 5 - 10 cm, nailed strongly vnatyag, excess trimmed.
4. Carve new upholstery - with little overlap, with holes under the eye, handles, locks - nail, the nail heads is covered with decorative elements.
5. The procedure for warming the surrounding wall is the same as for the metal door.
6. Gaskets glued, nailed staples, nails or insert mortise.

Models with ribs inside edged MDF, allow the use of solid insulation. Leaf door without internal filling - both wooden and metal - insulated from the outside. To do this, on the edge of the leaf nailed frame of wooden slats. Inside paste layer thin soft insulation over adhesive qualities ekokozha. The thickness of the new frame should not greatly exceed the thickness of the door leaf.

High-quality insulation will completely measurable results: the lack of a draft, the door leaf temperature exterior walls or warmer, a piece of paper inserted between the frame and the door shall be removable with little effort.
