'The Drymatic mat material are tested to UL 964 – Flammability of Shells Test and UL 964 – Ease of Ignition Test and are certified to DIN 4102 B1 and BS7837 which is flame-retardant, so will not continue to burn on their own after the heat source is removed'
The Drymatic Skirting T-Piece Connector has been designed to avoid air leakage while connecting 150mm (6 inch) ducting from Boost Bar to a wall or floor mat. The T-Piece connector can be open on both ends or seal itself to keep just one side open and provide more of an L-Shape.
