Specifying and fitting

Slab-edge fire stops

The board closes the gap between each floor slab and the curtain wall. TSFB is the black board for stops that stay visible behind glazing. The stop is a tested assembly from the curtain wall or fire-stopping supplier. Send its reference and the gap width, and we confirm the grade and thickness.

Cavity barriers in ventilated facades

Stone wool barriers divide the cavity of a ventilated or rainscreen facade at floor and compartment lines. Barrier size and fixing follow the facade system's tested details.

Service penetrations

Stone wool packs the gap around ducts, pipes and cable trays that pass through fire-rated walls and floors, together with the sealant of the firestop manufacturer's tested system.
