Thermafiber® FireSpan® FF 40 & FF 90
WHY CHOOSE MINERAL WOOL INSULATION?
Thermafiber® FireSpan® mineral wool insulation products are designed to maximize fire safety within commercial buildings by providing fire protection in curtain wall and perimeter fire containment systems.
Description
Thermafiber® introduces the first formaldehyde free, GreenGuard® Gold certified perimeter fire containment mineral wool insulation in North America. FireSpan® is designed to provide enhanced fire protection in curtain wall and perimeter fire containment systems and meet green building standards by using products that exclude red list materials like formaldehyde. These products are non-combustible, moisture-resistant, non-corrosive, non-deteriorating, mildew resistant, and vermin-resistant.1 Its natural dark color provides shadowing in glass spandrels. FireSpan® FF 40 & 90 insulations provide thermal insulation, fire containment, enhanced acoustical performance, and vapor control in many different UL and Intertek (formerly OPL) listed fire containment assemblies of 1, 2, and 3-hr ratings. The new formaldehyde free FireSpan products are especially appropriate for applications in education, healthcare, and other institutions committed to indoor air quality.
