A unique innovation in door seal design, FlexiTwin combines excellent acoustic sealing properties against the spread of noise as well as cold, smoke and draughts. When combined with the rigid PVC holder and Pyro100 / 500 intumescent material this seal adds superb resistance to fire spread. The 5mm twin fins trap air pockets thus increasing sound resistance.
