Doors with thermal break: the main advantages and popular models

If you choose the house entrance groupNote on the door with a thermal break. These products have a number of advantages, and therefore are in steady consumer demand. We offer to meet with the distinctive features of such non-frozen construction.

Thermorupture in metallic doors: what it is and how it works

To understand the design features of these door systems, it is worth to know what thermorupture in metal doors, and why it is used. The principle of operation of such structures is based on the laws of physics. The difference between the degree of heating the air inside and outside the building is leveled by using a special layer having a low thermal conductivity. The insert was sandwiched between insulating materials.

«In accordance with regulatory requirements, to the door system to work efficiently, the temperature difference between the outside air and the air inside the house should not exceed 40ºC. »

An insulating layer mounted so as to ensure complete coverage of the inner surface of the sash. The resulting thermorupture prevents heating of the outer side flaps, thereby reducing heat loss. A similar effect is achieved by installing a double door system.

Advantages and disadvantages of the entrance doors with thermal break for a country house

The main advantages of these door systems should include:

Among the shortcomings entrance doors with thermal break for a country house it is worth noting their high cost and increased requirements for the installation work. Most minor deviations can lead to a loss of thermal insulation performance.

Design and operation of the street door in a private house with a thermal break

High performance street doors in a private home with a thermal break due to their structural features. The design of such products include:

• a metal frame, made of steel with a thickness of 3 mm;
• an insulating layer inserted between the insulation and the metal frame and completely covering the inner surface;
• fixing system doors. Large sash weights places high demands on hardware and fittings. For reliable fixing flaps in the box using special levers as conventional hinges are not able to cope with such a task;
• insulation. It is located inside the metal frame of a special layer. The number and characteristics of insulation used depends on the particular model.

Given the good thermal conductivity of the metal structures, door leaf, without thermal break will be enough cold in winter, as these products by the laws of physics will tend to equalize the inside temperature and outside. Often on the door leaf condensation appears in such a situation.

Manufacturing process webs with thermal assumes its division into two separate structures. Thus one has a temperature close to the temperature of the outside air and the other - to the temperature inside. Thanks to this principle works manage to keep warm, to prevent condensation and subsequent freezing of construction.

Materials manufacturing metal entrance street insulated doors with thermal break

The characteristics of the material used for manufacturing input groups can have a significant influence on their lifetime and performance. In the production of such products as heat insulator can be used:

• PVC. Model with heater is a good choice for areas with warm winters and mild climate;
• mineral wool. Providing sufficient air tightness, heat insulator loses its properties at -25 ° C;
• Styrofoam. With a light weight material reduces the overall weight of the sash. However, it is not recommended to acquire the regions in which the night air temperature falls below -25 ° C, similar models;
• cork sheet. Used for heat insulation of premium fabrics;
• Styrofoam. Budget insulation;
• fiberglass. Suitable option for regions with harsh climates. However, under high temperature they may cause occurrence of harmful substances.

For exterior trim input street insulated metal door with a thermal break can be used:

• MDF. Budget option, presented in a variety of colors;
• thin steel sheet Powder coated. Products exhibit resistance to mechanical impact;
• array. Used in the manufacture of high-quality high-priced models.
