Fire doors are specially designed doors that prevent the rapid spread of flames, smoke and heat. Fire doors are divided into groups according to fire resistance. Fire resistance is then defined as a period of time after which it resists flames and high temperatures. Fire doors are designed for apartments, houses and office buildings. In terms of fire resistance criteria CŠN 730810 divides into EW - limiting fire, which monitors the amount of radiant heat emanating from the surface on the side away from the fire. El - preventing the fire on which the surface temperature is monitored on the side facing away from the fire. Fire doors will help protect property and are a statutory standard for the approval of an apartment. The Fire Brigade Door must be fitted with fire stoppers to prevent the fire from spreading freely. Doors also protect escape routes.
