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