ROCKWOOL ROXUL SAFE™ 65 is a mineral wool insulation board approved for use in metal building assemblies where a 1-hour fire resistance rating is required from one side or both sides of the wall.

ROCKWOOL ROXUL SAFE™ 65 is a medium-density stone wool insulation for exterior and interior non-loadbearing, steel-faced firewall applications where a fire resistance rating is required. It is approved for use in a 1-hour fire-rated system.

Designed to meet building codes in high-density areas, ROXUL SAFE™ 65 is non-combustible, withstanding temperatures up to 2150°F (1177°C), and will not produce toxic smoke or promote flame spread. As a result, it provides high-temperature fire protection, enhancing occupant safety, particularly when a fire separation wall is required. It is also UL/ULC tested and approved for fire-rated assemblies.

ROCKWOOL offers single- or double-sided fire-rated assemblies. ROXUL SAFE™ 65 is ideally suited for zero lot line applications where buildings are in close proximity and fire safety is essential.
