ROCKWOOL · Insulation
ROXUL Safe®
ROCKWOOL ROXUL Safe® is a stone wool fireblocking insulation designed to fill perimeter gaps between concrete floor slabs and exterior wall systems, between firewalls and ceiling slabs, through penetrations, and around conduit pipes and duct openings.
ROXUL Safe is noncombustible and fire resistant, and will not develop toxic smoke or promote flame spread. It is a component of ASTM E2307 tested and approved perimeter fire containment systems, and is always used in conjunction with a fire sealant in tested and approved systems.

Why Stone Wool+
Noncombustible and fire resistant — stone wool works to contain a fire and prevent its spread.
Will not develop toxic smoke or promote flame spread, even when exposed directly to a fire.
Water repellent to resist absorption and enhance an assembly's drying potential.
Nondirectional fiber orientation helps absorb sound moving between interior spaces and noise from the exterior.
Dimensionally stable: stone wool does not expand or contract due to temperature variances.
