As traditional spandrels continue to shrink or are eliminated altogether by floor-to-ceiling vision glass curtain walls designed for aesthetics, zero spandrel systems grow in popularity in the commercial building industry. The Thermafiber® Impasse® Zero Spandrel Perimeter Fire Containment System is a patent-pending design that revolutionizes the way zero spandrel systems are built with sturdier FireSpan® 120 mineral wool insulation and innovative Impasse® 2.0 Hanger technology. This robust system eliminates the need for costly and bulky back pans, accommodates various curtain wall anchors, allows for less penetrations in the curtain wall framing, does not require a backer reinforcement member, and offers flexibility for various shadowbox designs.1 The Thermafiber® Impasse® Zero Spandrel System is tested and listed with Intertek® Laboratories and provides up to 3 hours of perimeter fire containment.
