Fischer fire barrier is an effective ventilated fire barrier designed to close the void between the inner and outer construction elements. The horizontal, VentiStop Cavity Barrier – FFB-VS is 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 50mm ventilation gap, that allows airflow and moisture to pass down the back of the cladding. Under fire conditions, the powerful intumescent along the front edge expands horizontally to close the gap and prevent the passage of fire.

The product is encased with an aluminium foil face which provides class ‘O’ rating and exhibits excellent resistance to smoke. The FCFcl Cavity Clad provides a resilient lateral compression which is required to ensure a tight fit.
