Can Thermafiber Safing insulation be used with other types of insulation?
Thermafiber Safing insulation, in conjunction with Thermafiber FireSpan 90 or FireSpan 40 insulation, provides fire containment at the perimeter of high-rise buildings by confining the fire to the floor of origin. Extensive fire testing has shown that low-melt-point insulations (such as glass fiber and foam plastic types) do not protect the integrity of spandrel panels. Low-melt-point insulations used in combination with Thermafiber Safing insulation negate the fire containment performance of the Safing insulation.
