Product description

Rexalit is used for the cable feed-through of combustible and non-combustible pipes in accordance with the pipe system directive (MLAR/LAR) for feed-throughs through walls and ceilings. Due to its high temperature resistance, it prevents the spread of fire and smoke between fire compartments. The material consists of silicate fibers with aluminum lamination on one side and is harmless to health as the fibers are biosoluble.
