ROXUL has introduced ROXUL SAFE®, a new line of board insulation products specifically engineered and produced as a fire-stopping material for commercial, industrial, and residential buildings. Lightweight and semi-rigid, ROXUL SAFE is noncombustible stone wool insulation that is available in four variations. Used in facilities, these products help address commercial fire threats.
ROXUL SAFE is designed for commercial, industrial, and residential buildings as a fire stopping insulation. Ideal for filling: perimeter gaps between concrete floor slabs and exterior wall systems; around conduit pipe and duct openings through walls and floor slabs; and between fire walls and ceiling slabs. ROXUL SAFE® is used in conjunction with a fire sealant to prevent passage of fire and smoke.
ROXUL SAFE 65 holds a fire resistance rating of one hour, from the interior side, as specified in ULC Design No. W605 and UL Design No. U654. It also holds a fire resistance rating of one hour from both sides, as specified in ULC Design No. W610 and UL Design No. U658.
ROXUL SAFE 55 holds a fire resistance rating of two hours, from the interior side, as specified in ULC Design No. W606 and UL Design No. U655. In addition, it holds a fire resistance rating of two hours from both sides, as specified in ULC Design No. W611 and UL Design No. U659
ROXUL SAFE 55 and ROXUL SAFE 65 provide added fire protection for metal buildings in close proximity to other buildings and is designed for interior or exterior non-load bearing metal panel wall assemblies where a fire resistance rating is required. It is ideal for energy efficient, zero lot line applications where fire resistance ratings are required.
ROXUL SAFE 45 (Commercial Insulated Sheathing) is a semi-rigid, non-combustible, stone wool insulation board designed for use as an exterior continuous insulation in commercial applications. This thermally efficient, moisture resistant, vapor permeable board is effective against fire, moisture, thermal bridging and allows for superior drying potential.
The fire resistance properties of ROXUL SAFE, including a high melting point and low thermal conductivity, allows the insulation to act as a shield against fire and temperature. ROXUL SAFE products are fire resistant up to 2,150˚F (1,177˚C). ASTM testing demonstrates the products’ non-combustibility and additional benefits such as not contributing to toxic smoke/gases or flame spread.
