VentiStop Cavity Barrier - FFB VS

Effective ventilated fire barrier designed to close the void between the inner and outer construction elements

FFB-VS a foil-faced stone wool pre-cut unit, which has a powerful intumescent graphite strip bonded to the exposed face. The intumescent graphite strip is pre-wrapped with a durable polythene adhesive sheet to prevent water ingress. FFB-VS has been designed to provide a 25 and 50 mm ventilation gap, that allows air flow and moisture to pass down the back of the cladding. Under fire conditions, the powerful intu-mescent along the front edge expands horizontally to close the gap and prevent the passage of fire.
