The entrance door should not only reliably protect your room from invasion of foreign people, but also prevent the penetration of cold air. Therefore, it is very important to worry about the high-quality insulation of the entrance door immediately after its installation, if you prefer the acquisition of an inexpensive model with a bad filler or its fullest.

A properly insulated door helps to reduce heat loss by 20%, which is indoors. Consider the options of insulation:
mineral wool has good sound and thermal insulation qualities, resistant to high temperatures, does not waste the design;
the foam rubber has a high degree of protection against noise, unstable to temperature drops and eventually begins to crumble;
polyfoam ensures reliable protection against the penetration of cold air, does not absorb moisture and allows you to save money at the expense of low cost.

Required tools for work:
material for insulation;
mounting foam;
liquid Nails;
self-tapping screw;
lobzik and screwdriver;
leaf of laminated fiberboard.

After selecting one or another insulation, you can start mounting. Depending on the design of the door leaf, insulation is carried out from the inside or outside. If the inner part of the door housing is attached with the help of screws, it is dismantled and laid insulation inside between rigidity ribs. The particle parts are glued to the surface of the door with liquid nails. For complete thermal insulation of emptiness fill the mounting foam. Using a screwdriver, removed the trim is mounted on the previous place.

In the event that the metal door does not have removable panels, the installation of the insulation is performed on the inside of the door. Ultimately, the door becomes more in thickness. First of all, a sheet of fiberboard is prepared, which will close the insulation. The dimensions of the door are applied onto the sheet, the dimensions of the handle, lock and the door eye are noted. Dimensions are fixed with a jigsaw. On the inside of the door with self-drawing, a frame of wooden rails is strengthened. The resulting niches are filled with insulation using liquid nails. The fastening of laminated DVP begins on top with a screwdriver. The formed holes overlap with special plugs.

Another option of insulation is to glue the soft foam on the inner surface of the metal door. The size of the insulation material should be a little more door sizes. The foam rubber is glued with liquid nails on the surface purified from dust and is cut after complete drying of the adhesive. Up the insulated surface is attached upholstery material. The fabric is glued on top and bottom, and then on the sides. But note that the surface of the upholstery is unstable to mechanical damage.
6
It is important to glue the seal around the perimeter of the metal door. Since a large amount of cold can penetrate the slots between the entrance door and the door frame. You can use the residues of the foam or upholstery. But the best solution will be the use of a rubber seal, which will serve longer.
Do not forget to replace the insulation over time, if you felt that the door began to skip cold air. Any material over time sends and isolating isolation.
