Modern technology of thermal break in the entrance doors.
Entrance doors of any house, private sector or megalopolis, serve as protection from the external environment and danger, therefore they are made of durable steel material. Steel does not retain heat well, and in the autumn-winter period, iron doors are cooled, this makes it cold and uncomfortable in an apartment or house. Warming in the usual way is ineffective.
To maximize the preservation of intra-apartment heat, modern technology is used, which is based on temperature separation.
This technology guarantees high thermal insulation of steel doors.
If you understand the basics of thermal break technology in entrance door structures, you will understand their reliability in keeping heat, and contribute to the further choice as protection of your own home.
In cold weather, the temperature of the outer surface of the door drops significantly, the door elements and insulation let the cold inside, and the surface from the side of the apartment or house also cools. As a result, the room temperature drops, and condensation on the metal surface is also not excluded. Thermal break technology is a modern solution to the problem, eliminating heat transfer between door surfaces.
The metal sheets that make up the door are separated according to the temperature principle, that is, the outer and inner surfaces maintain their own temperature, cold and room temperature, respectively.
The doors, designed according to the principle of temperature separation, protect the entrance from the cold. Perfect for country houses, apartments on the ground floor, as well as offices with direct access to the street.
The design of thermal break is not just an insulation material on a metal door, but a whole technology, including a number of measures that allow you to isolate the outer side of the door from the inner surface.
The thermal break technology is based on the use of insulating materials of low thermal conductivity inside the door block, which form several layers, like a "cake".
As a result, the insulation effect is maximized.
The technology involves the use of small heat-insulating parts in the door structure, which connect the metal sheets to each other.
A system of thermal insulation of the metal door frame is also provided. The box is made of special structural parts, the inner cavity consists of high quality insulation.
The contours of the door structure are double insulated, which eliminates the presence of any gaps between the door and the frame when it is closed.
Various materials are used to create the effect of thermal break of the metal structure and door frame.
To fill the inner part of the canvas use:
- -Polyurethane foam, which gives strength to the structure. It is poured into the door cavity as a liquid. When solidified, the material provides a solid bond of the door sheets on both sides, creates high thermal insulation.
- - Styrofoam helps retain heat and provides sound insulation.
- -Cork separates the insulation layers among themselves.
- -Isolone and penofol.
Some budget models use foam and mineral wool. It is necessary to be very careful when dealing with door models containing mineral wool.
According to its composition, it is hygroscopic, and as soon as the material absorbs water, it can lose its heat retention properties.
Also, after a while, its volume may become smaller.
Fiberglass is used in some designs. This material cannot be used in hot countries and southern cities, the material, when heated, releases hazardous substances.
It is not allowed to use cardboard and materials similar to it as thermal insulation.
For the insulation of door frames, use:
Expensive, but high thermal insulation effect.
Thermal break technology prevents the slightest transfer of cold from the outer surface to the inner side of the door.
Designs of doors with thermal separation have their own differences in the device.
Firstly, the inside of the door does not contain a heavy iron frame, the door sheets are interlocked with modern materials that retain heat.
Secondly, locks are used that do not form a gap, so the cold does not penetrate inside through the keyholes.
Thirdly, there are often no eyes on such doors.
Fourth, the surface of the door is completely treated with an anti-corrosion agent.
Also, the door structure, if desired, can be covered with materials made of wood, leatherette, etc.
This does not affect thermal insulation in any way, it only creates an aesthetic appearance.
To finally understand this technology, let's list its positive and negative sides.
- -High thermal insulation of the apartment and the house. One opening with a thermal break provides better protection from the cold than vestibules with two iron doors.
- -The construction of the metal structure prevents the formation of condensation, which prolongs the shelf life of the door.
- -During frost, frost does not form inside the door.
- -Soundproof properties of the door.
Thermal-break type doors ensure safety from the external environment and exclude the ingress of cold into the room, as a result, it becomes more comfortable in houses and apartments, and heating costs are reduced.
If you choose the right door model and deliver it with high quality, then the advantages of thermal break technology will delight you for many years.
