Thermal insulation NO BACKER BAR™

mineral woolpanelinterior

The patent pending No Backer Bar™ design incorporates years of research and testing to completely eliminate the backer bar used to compress the Safing insulation at the slab edge in a curtain wall fire containment assembly. This game-changing system is UL fire rated for both 2 and 3 hours. The design of this system also allows for thicker mineral wool insulation without increasing the mullion depth, which provides additional R-value and energy conservation. The No Backer Bar system incorporates several components of Thermafibers patented Impasse® system. One critical component of the No Backer Bar system is a new Thermafiber product called FireLedge™.
