Lorient LDPU Intumescent Door Perimeter Upgrade Seal
This thin high performance intumescent fire seal is used to upgrade the fire door assemblies that have perimeter clearances exceeding the 3mm specified in AS1905.1.
When exposed to elevated temperatures the intumescent core rapidly expands in volume to restrict the passage of fire, hot smoke and toxic gasses.
Door Frame Seals or Perimeter Seals
Seals designed for the gap between the door and the frame (up and down the jamb and across the head of the door) is termed “Door Frame Seals”. These are generally compression seals; some are mounted on the door stop or directly onto a plain frame of the door, thereby providing a door stop seal. Some seals can be fitted to the door or neatly rebated into the frame itself.
