The indoor fireproof door is generally made of wood. The wooden fireproof door uses fire-retardant wood products as the door frame, door leaf framework and door leaf panel. The door leaf is filled with non-toxic, harmless, energy-saving and environmental friendly fireproof and thermal insulation materials, and equipped with fireproof hardware fittings and fireproof glass, which can meet a certain fire resistance limit.
