Installation entrance doors with thermal break allows you to minimize heat loss in the cold season

Entrance door with thermal break: basic information on products

Main function front door is to protect the premises from the penetration of strangers. Most often, such structures are made of metal, which in itself is both an advantage and a disadvantage. On the one hand, such doors are reliable, safe and durable. They are able to withstand the long-term influence of atmospheric phenomena, for example, frost, wind, precipitation. On the other hand, a metal door becomes a source of heat loss, due to which the microclimate inside living rooms can be disturbed.

Not all customer reviews left on metal entrance doors are positive, since all the advantages are inherent only in high-quality and expensive structures. In other cases, the owners of cottages and private houses are dealing with a partial loss of useful qualities during operation, rapid paint fading and even icing of products.

To avoid unpleasant surprises, as well as get rid of the flaws that are inherent in metal structures, you can buy outdoor doors with thermal breaks, which in many ways surpass conventional product options.

Features of doors with a thermal break: what it is and how it works

A street door with a thermal break is manufactured using a special technology. Due to this, the structure acquires increased resistance to the effects of atmospheric precipitation and temperature extremes, as well as damage caused by mechanical loads.

Such designs work based on simple laws of physics. The difference between the temperature conditions on the street and inside the house is leveled by the door, the thermal break occurs due to the presence of an insulating layer. It is made of a material with low thermal conductivity. In most cases, this interlayer is a polyamide insert that is sandwiched between several thermal insulation materials.

Note! According to GOST standards, the maximum allowable temperature difference between the living quarters and the street is 40 °. It is highly undesirable for the difference to exceed this figure.

The insulating layer is mounted on the inner surface of the door so that the entire area is covered with it. This insulating cake slows down the rate of heat transfer between adjacent materials and prevents the outside of the product from heating up. As a result, heat losses are reduced. Previously, a similar effect was achieved by installing two doors with an air gap between them or arranging a vestibule. Today it is enough to buy entrance doors with a thermal break to keep the heat in the house.

Why is it profitable to buy a door with a thermal break

In some cases, the installation of two air-spaced structures may be appropriate. The empty space between the doors will serve as a kind of buffer, not allowing the cold to enter the room. Most often, for the installation of paired structures, products are taken made of materials with different thermal conductivity, for example, wood and metal.

However, the use of paired structures also has disadvantages:

  • the tightness of the closing of the sash is broken;
  • doors are sagging;
  • it is more difficult to enter and exit the room, since you will have to open two doors;
  • the technical requirements for the wall become more complicated, since a double box or two standard boxes for each door will be mounted in the opening;
  • useful space is lost.
