When protecting your residential or working space and its occupants from the dangers of a fire, you cannot rely on regular wooden doors. They are not able to withstand extreme temperatures in a fire emergency. You need doors made of unique materials that can withstand extreme temperatures during a fire emergency. This is where fire-rated doors come to the fore. Premium and Durable Fire-rated doors are constructed of fire-resistant materials like timber, glass, steel, gypsum and vermiculite boards. The primary purpose of using a fire-rated door in a building or home is to restrict and delay the spread of fire, smoke, and fumes from one part of the building to another.
