The Impasse Curtain Wall Insulation System from Thermafiber provides a fire-protective barrier between the fire source and the curtainwall, as well as a barrier extension between the floor slab perimeter and the curtainwall assembly. A stepwise technique of overlapping components during installation to lock the fire barrier materials in place eliminates the possibility of insulation materials being dislodged by the violent and turbulent air forces produced during fires.
