ROCKWOOL Safe'n'Sound® is a stone wool batt insulation designed for interior wall partitions, floors, and ceilings for wood and steel frame construction where superior fire resistance and acoustical performance is required. Withstanding temperatures up to 2150°F (1177°C), Safe'n'Sound® is non-combustible and will not produce toxic smoke or promote flame spreading, even when directly exposed to fire. This adds valuable extra time for people to reach safety and for fire services personnel to arrive.
