Johns Manville CladStone Water & Fire Block insulation is manufactured from inorganic fibres derived from volcanic rock. Advanced manufacturing technology ensures consistent product quality, with high-fibre density and low shot content for excellent performance. Noncombustible, with water-repellent properties, it is ideal for wall cavity and rainscreen applications.
Water-Repellent: Repels water to ensure drainage when applied as part of a proper exterior wall cavity system.
Fire-Resistant: Melting point in excess of 1093˚C (2000˚F).
Durable Inorganic Glass: No growth of fungi. No sustaining of vermin.
Burning Characteristics: Flame Spread of 0 and Smoke Developed of 0.
Quick Installation: No sagging or slumping.
