The Thermafiber® Impasse® Perimeter Fire Containment System is a patented design that streamlines the installation of curtain wall insulation by changing the order of traditional installation steps to fit a logical progression and take full advantage of the fire-resistive, enhanced acoustical performance and vapor barrier properties of Thermafiber, FireSpan® and Safing insulations. Traditional curtain wall insulation systems call for installation of impaling pins attached to the spandrel perimeter before installation of insulation, The insulation is then impaled onto the pins. The Thermafiber® Impasse® System is unique in that the hangers are inserted into the insulation before the insulation is installed into the spandrel opening, This technique saves time and money, The Thermafiber® Impasse® System is tested and listed with UL® Laboratories and provides up to 21 hours of perimeter fire containment.
