Linear Deflection Detail at Internal Escape Route Compartment Wall Heads

With no deflection detail at the dry wall head construction, a detail specific joint seal installation was site trialed in a finished and live building environment, subject to test data the client approved the methodology. This system was then fire tested at Exova Warrington Fire facility and found to perform as required for 120 minutes protection.
