Description

Mineral Wool SF16 & SF24 are a premium semi-rigid stone wool batt insulation for exterior wood/steel stud assemblies in new builds and renovations. Its innovative flexible edges compress during installation, then spring back to seal studs and fill wall cavities fully—ensuring easy fitting and consistent rated R-value. Non-combustible with strong fire resistance, it retains integrity under direct flame, emits no toxic smoke, and stops flame spread (meeting strict fire standards). It also resists water/moisture (preventing mold) and offers excellent sound absorbency for better indoor acoustics. A high-performance choice for home energy efficiency, it cuts wall heat transfer to lower HVAC loads. GREENGUARD and ULC certified, it supports healthier, safer interiors.
