Wood Fire Door

Main performance

Classified by fire resistance performance:

Heat-insulating fireproof door (Class A): A fireproof door that can simultaneously meet the requirements of fire integrity and heat insulation within the specified time.

Partially insulated fireproof door (Class B): A fireproof door that meets the requirements of fire integrity and heat insulation within the specified time of 0.50 hours or more, and still meets the requirements of fire integrity within the specified time after 0.50 hours.

Non-insulating fireproof door (Class C): A fireproof door that can meet the requirements of fire integrity within the specified time.

Fire resistance limit

Fire resistance limits of commonly used Class A fireproof doors:

Class A grade is 1.05 hours (A1.50), Class A Grade B is 1.00 hours (A1.00), and Class A Grade C is 0.50 hours (A0.50).

The fire resistance limits of Class B and Class C fire doors are (B3.00, B2.00, B1.00, C3.00, C2.00, C1.50, C1.00).

Sound insulation effect

It has a good sound insulation effect, reducing noise by more than 35db.

Scope of application

It is applicable to the safety passages in places with fire protection requirements in high-rise buildings and industrial buildings (such as hotels, restaurants, cinemas, warehouses, reference rooms, computer rooms, distribution rooms, room entrance doors, etc.).
