In fact, fireproof doors refer to doors that can meet the requirements of fire resistance stability, integrity, and thermal insulation within a certain period of time. They can prevent the spread of fires, prevent the spread of smoke, and buy time for people to escape. Be careful, however, that fire doors are not truly non combustible doors.
