Decades of leadership in curtain wall fire containment systems

Thermafiber pioneered the testing of curtain wall fire containment in 1971 and continues to raise the bar with new tests each year. Our newest innovation, the Impasse® curtain wall insulation system, overlaps components during installation to lock in the fire barrier, virtually eliminating the possibility of insulation materials becoming dislodged by fire’s turbulent forces. Proprietary hangers also make installation of the Impasse system simple, accurate and fast. Thermafiber’s Safing insulation and FireSpan® 90 and FireSpan® 40 curtain wall insulations are approved for use in perimeter fire containment assemblies listed by UL® and Intertek.
