The main function of the entrance door is to protectunauthorized penetration. However, it should provide a decent level of isolation from cold and street noise. This can only be achieved if you purchase quality insulants for the door. Take into account that modern materials of this kind provide quite adequate level of thermal insulation, so that in case of wrong choice, you will immediately encounter two problems.

As a result, a vestibule is produced, which is an excellent air cushion, which reliably protects the internal premises from the ingress of cold air.
But today we will discuss the insulation of the door leaf directly. Until recently, for this purpose, a standard list of widely used and cheap materials was used, which went to the upholstery of the door. It:
- synthetic leather;
- some types of tissues.

Almost all modern doors are produced with a layer of insulation inside. As such, the following materials can be used:
- corrugated cardboard;
- mineral wool;
- expanded polystyrene;
- simple foam rubber.
If you have purchased a simple wooden door,The only way to warm it up is the upholstery we have already mentioned. As an outer layer it is better to use a skin substitute or a dense fabric, under which you put cotton or foam.
It is strongly advised not to purchase for thesevarious types of mineral wool. These heaters for the door have good performance, but over time quickly get lost in one lump and almost completely lose the thermal insulation properties.
More recently, for this purpose,natural cotton wool. It had good performance characteristics, but it was an excellent substrate for the multiplication of various pests. Not to mention the fact that natural material serves as an excellent substrate for mold and fungi, which do not work best for the health of those who live in the house.
Foam rubber is much better protected from cold, but extremelyshort-lived. After three to five years, it will turn into dust, and you will have to re-warm the door. Where is more reliable izolon. This is a modern and durable material that will permanently protect your home from the cold. Such insulation for doors, the price of which does not exceed 10-20 rubles. per meter, would be an excellent choice even with a limited budget.
