Ventilated Cavity Barriers

Ventilated cavity barriers are designed mainly for rainscreen cavities, to avoid condensation build up, whilst providing effective fire compartmentalisation.

They have an intumescent strip on one side, which in the event of a fire expands to seal off the cavity.

They can only be installed horizontally, as this is how they are fire tested.

Some barriers need fixing brackets, whilst others need adhesive and sometimes screws or nails. Always follow the installation instructions for the barrier you are installing.
