Front door with a thermal break and its technical characteristics

From this article you can find out what features the front door has with a thermal break. Consider the internal structure and purpose of these products, the classification of existing structures and technical characteristics that are inherent in them. The article contains a brief overview of the products of the most sought-after manufacturers, a comparison of prices for thermal doors, as well as their parameters.

Entry door with thermal break: basic information on products

The main function of the front door is to protect the premises from the penetration of outsiders. 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, durable. They are able to withstand the long-term influence of atmospheric phenomena, such as frost, wind, precipitation. On the other hand, the metal door becomes a source of heat loss, because of which the microclimate inside the living rooms can be broken.

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

To avoid unpleasant surprises, as well as to get rid of the shortcomings that are characteristic of metal structures, you can buy street doors with a thermal break, which in many ways surpass the usual versions of products.

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

Similar constructions work on the basis of 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 arises due to the presence of an insulating layer. It is made of a material with a low level of thermal conductivity. In most cases, this layer is a polyamide insert, which is placed between several insulating materials.

Note! According to GOST standards, the maximum allowable temperature difference between a dwelling and a 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 heat-insulating cake slows down the rate of heat transfer between adjacent materials and prevents the outside of the product from heating. As a result, heat losses are reduced. Previously, this effect was achieved by installing two doors with an air gap between them or arranging the vestibule. Today it is enough to buy entrance doors with a thermal break to keep the heat in the house.

In some cases, the installation of two structures with an air gap may be appropriate. The empty space between the doors will serve as a kind of buffer, not letting the cold into the room. Most often for the installation of paired structures are taken products made from materials with different thermal conductivity, such as wood and metal.

However, the use of paired structures has disadvantages:

  • tightness of closing of a shutter is broken;
  • the doors sagging;
  • it is more difficult to enter the room and get out of it, since it is necessary to open two doors;
  • technical requirements for the wall are complicated, since a double box or two standard ones under each door will be mounted in the opening;
  • the useful space is lost.

Installing outdoor doors with a thermal break in a private house offers significantly more benefits:

  • the absence of freezing of both the door itself and the block with a lock;
  • high level of noise insulation;
  • suitable for regions with harsh climatic conditions;
  • there is no need for arranging additional thermal control protection around the structure;
  • no need to use additional insulation and seal.

In the positive reviews of the owners of doors with a thermal break, there are other advantages that distinguish these products from conventional designs:

  • reinforced construction by increasing the stability of the box and the heavy door leaf made of dense material;
  • increased margin of safety in the furniture filling;
  • reliable framework with the strong basis;
  • high quality performance.

In addition, insulated metal outdoor doors with a thermal break have additional features such as resistance to high pressure and tightness.

Note! In the photo of metal entrance doors of standard type you can see a lot of design variations. Unlike conventional designs, products with thermal break function are not so diverse. Preferring secondary design, manufacturers pay more attention to quality control and maintaining technology standards.

Having completed the installation of the entrance metal door with a thermal break, it is possible to significantly reduce the cost of heating the house, because the efficiency of heat preservation increases. This advantage will be particularly beneficial for homes in which heating is carried out at the expense of electricity.

Consider the characteristics and advantages of street doors with a thermal break:

  • profitability by reducing the cost of heating;
  • reliable build system;
  • ease of use;
  • high quality coating;
  • resistance to frost and ice;
  • the probability of formation of condensate is excluded;
  • high level of sound insulation;
  • high degree of fire safety;
  • endurance under the influence of low temperatures.

Despite the large number of advantages, steel doors with thermal breaks have disadvantages. The presence of all the above benefits depends on several conditions that must be followed. First, if the operating conditions of the doors are accompanied by high humidity, there will be a risk of ice formation. To avoid this, it is necessary to organize a supply and exhaust ventilation system.

Secondly, entrance doors for a country house with a thermal break put forward increased requirements with regard to the quality of installation work. Slope, bias, deformation changes of the fabric – any error made during installation can negate the thermal insulation qualities of the structure.

Thirdly, it will be necessary to buy handles with a similar function as an additional set to the entrance door with a thermal break. Conventional fittings will serve as a source of heat leakage.

When choosing a product, it is desirable to pay attention to the quality and characteristics of the insulating material. The framework of reliable designs is made of thick sheet steel. At the same time, the width remains standard – about 86 cm. Steel has more advantageous characteristics than PVC or wood.

On sale there are products from thin steel. You should not buy at a low price and low weight of such doors because they are very easy to open. It’s enough to use a can opener. It is desirable that reinforcement be present on the canvas. A door with this design will be harder to crack.

Note! If the steel sheets are on both sides of the sash, then before buying the door you should check their integrity and ensure that there are no openings. Typically, the thickness of this material is 1.8 mm.

Most of the entrance doors with a thermal break for a private house has a heavy construction that can not but affect the performance and service life. To extend the period of effective use of the product, it must be equipped with reliable and durable hinges. Standard fixing elements are not suitable for this purpose. The best option would be special levers, securing the canvas in a stable position.

Various materials are used to fill the inside of the door. The insulating qualities of the products and their cost depend on them.

The main types of insulation materials:

  1. Polyvinyl chloride
  2. Mineral wool.
  3. Styrofoam.
  4. Fiberglass.

There are far from all manufacturers that produce products with the function of thermal break, but only those who are popular with customers and are actively expanding their dealer network. Many of them offer doors of varying cost and class. Therefore, each buyer can choose the design in accordance with their budget capabilities and climatic features of the region in which he lives.
