How to choose the right fire door, at an affordable price and appropriate characteristics? What indicators should you pay attention to first? All the answers can be found here.
Interior and entrance doors have long been an integral element of the interior of any room, anywhere in the world. They carry out not only their functional duties — protection from unwanted intrusion and maintaining proper temperature conditions inside — but also purely decorative functions. The Russian market offers a huge range of different doors, of any texture, any color, from a wide variety of materials and in a huge price range. Therefore, when planning an interior, attention is often paid not so much to the functional content of the door as to its compliance with the overall style of the room. And sometimes beauty is preferred to safety.
Manufacturers develop their products in accordance with all safety and comfort standards: air- and noise-proof, with increased strength characteristics. However, the main factor that affects the danger of being indoors is fire safety. When fires occur indoors, most people die not only because of fire, but also because of carbon monoxide. new generation fire doors, thanks to their special design, ensure tightness, heat resistance (up to 1800 0C) and reliability.
Such unique characteristics are achieved due to the design features: reinforced frame, the inner surface is filled with soundproof and flame-retardant material — mineral wool or synthetic non-flammable material like Rocwool. Such doors can be both external and internal, and heat-resistant metal sheets and steel profiles are used for surface cladding. The interior area is often enclosed by partitions. A thermal insulation insert is installed in a special groove around the perimeter, which protects the room from toxic oxidation products. Fire doors have their own markings corresponding to the time of fire protection (from 15 minutes to 2 hours).
The production conditions of fire doors must comply with GOST standards, which is confirmed by laboratory test certificates. That is why it is advantageous to purchase high-quality doors in bulk from the manufacturer directly. When choosing a door, it is necessary to pay attention to the fire resistance limit, which must be calculated with the following calculation: an apartment burns out completely in 20 minutes, an office in 40 minutes, and the above indicator should not be less.
As a rule, three main markings are established in the technical data sheet:
R is an indicator of loss of bearing capacity (resistance to collapse and deformation);
E — loss of integrity (resistance to loss of tightness);
I — loss of thermal insulation ability.
During evacuation, no less attention should be paid to the strength and design of locks and door handles. Most fire-resistant doors are equipped with an "anti-panic" system, that is, when the doors are easily opened from the inside without using a key.
