ROCKWOOL CURTAINROCK® 40 is a rigid, mineral wool insulation board designed for fire rated curtain wall applications.

ROCKWOOL CURTAINROCK® 40 is a stone wool insulation board designed for a variety of curtain wall systems. CURTAINROCK® is non-combustible and fire resistant, and will not develop toxic smoke or promote flame spread, even when exposed directly to a fire.

When CURTAINROCK® 40 is used with ROCKWOOL ROXUL SAFE™, they provide a comprehensive fire-stopping system that has been UL/ULC/Intertek tested and approved for perimeter fire containment systems.

ROCKWOOL insulation has excellent acoustic properties and is dimensionally stable – maintaining thermal performance over their lifetime, even in rising and falling temperatures. This contributes to the optimal performance of a building envelope.

CURTAINROCK® products are available with or without reinforced foil facing (RFF).
