Waterproofing and sealing materials for cable tray holes
In Walls: Use a fire-rated, intumescent caulk or putty for gaps around cables in fire-rated walls. For non-fire-rated walls, silicone caulk provides a flexible, weather-resistant seal. Due to cable entry seals expected to protect and insulate cables from external forces such as air, moisture, light and physical impact, we recommend foam as an ideal material which supports these requirements while being a highly compressible and versatile material. The cable entry seals include sealing modules in the form of rubber blocks with Multidiameter™, our. The effective weatherproofing of cable trays helps to keep weather out, preventing damage to the building envelope, avoiding thermal breaks, maintaining the indoor environment and helping to keep the various cables and wires protected. WSP weatherstops are designed to seal penetrations of any type in walls or floors by cable tray, cable conduit, pipe and/or bus duct.
