Cavityrock is a semi-rigid insulation board designed for exterior cavity wall and rain screen applications. These products offer superior long-term thermal efficiency, fire resistance, moisture control, acoustic performance and are compatible with numerous framing systems and cladding attachment systems. Cavityrock are there in mono-density and in dual-density. The unique dual-density insulation combines a high density outer layer and a more compliant, low density inner layer that are created simultaneously in the proprietary manufacturing process. Features: Non-combustible stone wool insulation with melting point of approximately 1177 degreeC (2150 degreeF) Fire resistant due to its high melting temperature Water and moisture resistant; does not absorb moisture to maintain insulating value Chemically inert Does not rot, fungi, promote mildew, or bacteria CFC- and HCFC- free product and process Made from natural and recycled materials Applicable Standards: ASTM C612, ASTM C303, ASTM E84 (UL 723), CAN/ULC S102, CAN/ULC S114, ASTM E136, ASTM C411, ASTM C518 (C177), ASTM C423, ASTM C1104, ASTM C1338, ASTM C795, ASTM C665, LEED
