Mineral Wool 4"X48"X72" Firespan 40 Foil Faced 24SF
Mineral Wool 4"X48"X72" Firespan 40 Foil Faced 24SF
Thermafiber® FireSpan® mineral wool insulation products are designed to provide enhanced fire protection in curtain wall and perimeter fire containment systems as well as enhanced performance in thermal and acoustical applications. Thermafiber® FireSpan® is available in 4.0 pcf, 8.0 pcf, and 12.0 pcf nominal densities for specific application needs. These products are noncombustible, moisture-resistant, noncorrosive, nondeteriorating, mildew-resistant, and vermin-resistant. Its natural color provides shadowing in glass spandrels. FireSpan® insulations provide thermal insulation, fire containment, enhanced acoustical performance, and vapor control in many different UL® and Intertek® listed fire containment assemblies of 1-, 2-, and 3-hour ratings.
