Hinged Acoustic Fire Doors

Acoustic steel hinged doors offer a high performance mechanically robust, long life solution to closing a pedestrian sized doorway to give easy, simple access.

Clark Door’s acoustic fire doors are designed with fire ratings to suit the most challenging of applications. Also known as acoustic swing doors or steel hinged doors they are usually fitted into the opening, meaning that the door frame reduces the clear opening by a small amount. They require space in the building in the direction of swing but offer a cost-effective option to main doorway access requirements.

All of these bespoke acoustic fire door options are offered with independently tested door furniture and locking system.
