Some models are equipped with an additional system, which allows you to open the locked door from the inside. The seals of fire doors, installed in the living room, should meet high ecological requirements.
Wooden doors have a particularly strong frame and dense fire seals. Last made of special material, which is foamed at very high temperatures. Such seals tightly seal gaps and then block the penetration of smoke into the room. The box of the door is often made of a solid wood and is tightly fitted to the door leaf.
