Metal doors with thermal break

The preservation of heat indoors depends on many factors, among which a large role is played by the type of entrance door. If a metal cloth is used, it passes heat very well. This leads to a significant loss of energy, which negatively affects the indoor climate. Metal doors with a thermal break can solve this problem.

Metal doors have unique abilities to quickly conduct heat, which leads to the formation of condensation on their surface. To exclude such a phenomenon, they are heat insulated.

Thermal break is just a kind of "cake" of heat-insulating materials that are placed between the walls of the structure. A feature of these systems is the presence of a thin layer of a substance that conducts heat very poorly. This part is located between the external and internal insulation materials.

Using a similar structure, the metal maintains an optimum temperature in the room, while it remains heated inside the house, while the sheet remains cold outside. This method of preserving heat replaced the use of two entrance doors, between which there was an air gap. This option is not only economically unprofitable, but also requires additional space for the installation of two structures.

Iron doors with a thermal break is a unique design that allows you to solve many problems.

This system is distinguished by several positive features:

• Exception of freezing. This allows you to protect not only the living space from the effects of frost, but also eliminate the breakage of locks from the formation of ice inside their grooves.
• Noise and thermal insulation. Doors do not let the heat and sounds on both sides, which allows you to create comfortable conditions in the room.
• Installation of the door eliminates the use of additional insulating inserts. The design completely provides high-quality functioning without use of a sealant.
• Using the door leaf, you can reduce heat loss, which saves money on its payment.
• Prevent the formation of condensate, which qualitatively affects the life of both the fabric and accessories.
• Many manufacturers protect doors with special substances that prevent the formation of corrosion.

It should be understood that the doors of this type are durable and heavy weight.

For a device to function reliably for a long time, it must meet several requirements:

• The surface of the door should be perfectly flat. The design should not have distortions or inclinations. If they are present, it does not guarantee that the web will last for a long time.
• Along the perimeter of the door leaf there must be a seal that will eliminate the formation of gaps.
• The product must be completely intact and without mechanical damage. It is important to always check this, since minimal imperfections can reduce the thermal insulation properties.
• Fittings must be of high quality and durable to withstand a large weight of the canvas.
• Installation of construction is carried out only as recommended by the manufacturer. Various deviations about them are not allowed.as this may lead to the formation of cold bridges or rapid failure of the product.

Making door leafs of this type is a rather complicated operation. Here it is important not only the quality of the metal, but also the substances with which the thermal break is formed. For such purposes, manufacturers use several materials:

• Inserts of polyvinyl chloride. A feature of this substance is a good value for money. The material retains heat quite well, which makes it possible to create a chamber inside the canvas that holds heat. This type of door can be used only in a temperate climate zone. If winter is accompanied by severe frosts, then the system will not be able to cope with low temperatures.
• Styrofoam. Relatively inexpensive material, which is also very affordable. Use it only in combination with mineral wool. Such a "cake" can withstand temperatures up to -25 degrees. Doors for temperate areas, where such a frost is rare, are suitable.
• Fiberglass. The substance has a high thermal conductivity.But if the material is heated to high temperatures, it can release toxic elements into the air. This is unacceptable, so the doors of it are used in regions where the summer temperature does not rise to high marks.
• Tree. One of the best thermal insulators. The material not only retains heat well, but is completely environmentally friendly. It is found in door frames very rarely, since such a construction is very expensive. Doors are made of it often only on order.

The market of metal doors today is very saturated.

Such designs produce many companies, among which are:

• Lex Thermo;
• Torex Snegir;
• Termo;
• "MedDver".

The cost of production of these manufacturers varies in a wide range. Quality doors can cost from 30 to 60 thousand rubles.

The market of doors with thermal break is so huge that it does not always allow to choose the right model. When buying such a product, you should pay attention to several indicators:

• The thickness of the metal. The doors must be durable, therefore they are made of sheets not less than 1.8 mm thick. If you find a thinner model, do not buy it, as it will not last long.
• The quality of heat preservation. One of the main factors is the material that is used to form a thermal break. It is also important to check the tightness of the sash to the seal. If there are gaps between them, this will lead to the formation of drafts and the penetration of cold.
• Fittings. Door service life depends on it. The hinges must be strong, as the canvas is very heavy. You should buy products with several locks, this will reduce the likelihood of hacking. In this case, pay attention to the rigidity of the box and the manufacturing technology of the frame. The best solution would be doors with hidden hinges.
• Manufacturer. Before buying, be sure to check reviews of a particular brand of doors. This will allow you to exclude the purchase of low-quality product for big money.

The popularity of doors with thermal break is growing rapidly. Many users note the high quality of the design and good heat retention.Some of them claim that the rooms become much warmer, even if they do not have heating appliances.

It should also be noted fittings, which retains its performance over several years. One of the drawbacks, according to buyers, is the considerable weight of the canvas (the mass of some modifications can reach more than 120 kg), which does not always allow children and elderly people to cope with them. Some say that cheap models still let in the cold, which leads to frost or condensation. To correct this deficiency can only replace the seal or thermal insulation.
