Fire stopping of cable penetrations

Avoid cable fires and stop them safely!

KBS® offers various solutions to effectively protect cable penetrations from the passage of flames and smoke.

In most cases, the task is to seal off complex cable systems and cables on support constructions. However, individual cables and cable bundles as well as electrical installation pipes can also be routed through walls and floors of fire compartments. These can be effectively protected against the passage of flames and smoke gases by using  KBS® Foamcoat HS or KBS® FR Caulking for fire stopping.

Fire protection mortar

KBS® Mortar is a fire protection mortar that swells after processing. It reliably seals the gaps around the cables and prevents cracks from forming when cured. This results in a flame- and smoke gas-tight sealing with a high yield.

KBS® Mortar is tested for use in cable penetration seals according to DIN 4102-9, BS 476 Part 20 and also according to UL 1479. KBS® Mortar is tested according to EN 1366-3 as mixed penetration seal.

KBS® Mortar is available in 2 colors: red for identification as fire protection mortar or in neutral grey.
