Wallthrough

The Allproof Wallthrough provides a fire-rated multi-service penetration solution for apartment and hotel room entry points. Its stainless steel sleeve, internally lined with intumescent material, ensures robust passive fire protection for services passing through fire-rated plasterboard walls. The system can be installed before services are run or retrofitted, making it ideal for flexible project timelines and retrofit scenarios.

    • Stainless steel sleeve with intumescent lining
    • Suitable for multi-service penetrations in fire-rated plasterboard walls
    • Pre-install or retrofit installation options
    • Includes NBR block seals and fire-rated sealant for smoke control
    • Compatible with FIREFLY Penowrap for fire integrity
