This material is made from minerals. It has quite large indicators in noise and heat insulation.

Basalt insulation door - this is mineral wool:

The use of mineral wool in the insulation of the door
  • High humidity and temperature drops will not harm it;
  • A rather high service life also speaks in favor of this material;

Let's look further at what heater to choose for the door.

Warming of doors with this material is done most often. You can see it in the photo and video. This design has many advantages over other materials.

  • Perfectly tolerates temperature extremes and high humidity. Installation on entrance doors is possible.

Plates foam

This material has all the positive qualities of the listed materials:

  • Making a construction using this material will provide both heat and sound insulation at the same time;
  • It is not subjected to stretching and compression, and therefore does not shrink for a long time;
  • It is not affected by temperature changes and high humidity;
  • Installation is possible and on its own and it looks attractive in the eyes of consumers.

Seals for door insulation

Warming of doors will not be complete without proper and high-quality installation of seals. They will not block all the gaps and gaps and will not allow cold air to enter the room.

  • Self-adhesive insulation for windows and doors. To install it, it is enough to remove the protective film and mount it;
  • Seal that must be glued independently. This is done by applying glue.

Attention: Self-adhesive insulation for windows and doors should be selected according to the installation profile. To do this, you must correctly determine its thickness. If this is not done correctly, then in the process of time the door is simply deformed by the opening.

We select the seal thickness

Many do not understand how this is done correctly. Here, after all, to correctly determine the thickness, this is the most important thing.

This is done as follows:

  • We take clay in the right amount;
  • We roll it in the form of a thread;
