Therm-A-Blade - Fire Door Seal

Therm-A-BLADE has been designed to enhance the smoke performance properties of Therm-A-Stop. The fire performance properties of both products are the same as they both contain the same intumescent (Therm-A-Flex, graphite intumescent). The specially developed elastomeric blades are very thin to give a very low deflection force thereby minimizing the opening and closing forces when operating the door.

The flexible elastomeric insert has been developed to give maximum fatigue resistance ensuring a long and satisfactory life when installed into the 3 to 4 mm gap between the door edge and frame.
