Thermafiber® Firespan®

Thermafiber® FireSpan® mineral wool insulation products are designed to provide enhanced fire protection in curtain wall and perimeter fire containment systems. These products are non-combustible, moisture-resistant, non-corrosive, non-deteriorating, mildew-resistant, and vermin-resistant. Additionally, its natural color provides shadowing in glass spandrels.

Thermafiber® FireSpan® is also the first formaldehyde-free, GREENGUARD® Gold certified perimeter fire containment mineral wool insulation in

North America when using the FF option. FireSpan® FF offers similar features as the other FireSpan® products, but it also meets green building standards by using products that exclude red list materials like formaldehyde.
