ROCKWOOL Curtainrock® 40 is a semi-rigid stone wool insulation board that will not expand or contract over time due to temperature variances in the curtain wall system, ensuring stable thermal performance over the lifetime of the insulation.
Curtainrock® 40 is non-combustible, fire resistant, and will not develop smoke or promote flame spread when exposed to fire, providing a critical line of defense in fire protection. Available with or without reinforced foil facing (RFF) in a variety of specifications, this product delivers superior sound attenuation characteristics. The unique multi-directional fiber structure and high density of the product reduce noise transmission into and out of the building.
