Cavity Barriers
High-density non-combustible stone wool fireboard for protecting the spandrel in curtain walls. This is specially engineered to facilitate advanced performance of CW-FS Firestop at the slab edge.
CW-FS Firestop restricts the movement of smoke or flame by sealing the gap between compartment floors or walls and the external façade.
RH Horizontal Cavity Barrier has been developed to meet the complex requirements of ventilated rainscreens. The Lamella stone wool barrier includes an integral strip of intumescent material along the leading edge.
RV Vertical Cavity Barrier is designed to fully fill the void between the external envelope and internal structure, preventing fire spreading across a compartment and helping to maintain air-pressurisation in ventilated façades.
