Fire door vents permit free air flow and can be fitted within 30 or 60 minute fire doors and walls, whilst maintaining the integrity of the fire compartment. Ideal for boiler room fire doors.
Fire door vents can be used in new or existing fire doors and can be mounted in a high or low position. Two vents are required with one intumescent fire block. Fire blocks offer low maintenance and low cost, giving up to 60 minutes integrity in accordance with BS 476 parts 20:22. Fire blocks have no moving parts and hence need no regular maintenance apart from inspection to ensure they have not been damaged.
