Required compression for installation is a mere 10%, and no overlapping is required. A clean wall solution with the fire block fitted within either metal or plastic trunking can be achieved with a single 150mm length. Cut to fit sizing reduces waste, and one sided installation ensures easy retrofitting.
Each fire block measures 30mm thick x 150mm wide x 1000mm long. Tested and compliant with BS EN 1363-1: 1999 for up to 120 minutes. Also qualifies for NHBC type approval.
