A fire-rated door is a type of door that is designed to prevent the spread of fire and smoke in a building. Fire-rated doors are made of materials that are resistant to fire, such as steel, gypsum, or glass, and are designed to seal tightly against the door frame to prevent the passage of flames and hot gases.
Fire-rated doors are an important component of building design because they help to keep occupants safe in the event of a fire. Fire-rated doors are typically required by building codes in areas such as stairwells, corridors, and mechanical rooms, and are frequently used in commercial and institutional buildings. In addition to preventing the spread of fire, fire-rated doors are also designed to provide a barrier against heat and smoke, which can be just as deadly as flames.
