CurtainRock 40 is a semi-rigid stone wool insulation board made for curtain wall systems, used behind the backpan or with mechanical fasteners. It is non-combustible, with a melting point near 2150°F, and is part of ROCKWOOL's tested perimeter fire containment line when paired with CurtainRock 80. It repels water, drains, resists rot and mildew, and absorbs sound, which makes it a fit for exterior wall assemblies that need fire and moisture performance. Against foam and fiberglass boards it trades a higher density and stiffer feel for fire resistance and moisture tolerance.
