Quelfire Rainscreen Barrier has been designed to provide a two hour fire rating where continuous vertical airflow is required behind a rainscreen cladding system.
The Quelfire Fixing Spike is fitted to the external surface of the inner blockwork, onto which the Quelfire Rainscreen Barrier is
then impaled. A Quelfire Spacer Spike is fitted to the external surface of the Rainscreen Barrier below the intumescent strip. The Spacer Spike ensures the 25mm airspace is maintained along the length of the fire break.
Quelfire Rainscreen Barrier can be used in conjunction with Quelfire Fire Stop Slab vertically. Vertical barriers fully fill the cavity while horizontal Rainscreen Barriers provide a fixed 25mm airspace. The provided Quelfire Spacer Spikes ensure the correct airspace is maintained during fitting.
