CS85™ is a high-strength, structural-grade type II calcium silicate insulation with an average density of 85 pcf (1362 kg/m³). It is an inorganic, non-combustible, high-temperature insulation designed for use in fire protection, heat processing, and electrical resistance applications. It can be used in systems operating at temperatures up to 1800°F (982°C). CS85 is manufactured primarily from lime, silica, and reinforcing fibers using a Tobermorite crystalline structure. This product is white in color, essentially dust-free, and contains no asbestos, mercury, or lead.
CS85™ is available in thicknesses from 1/4" (6mm) to 3" (76mm) and is supplied in standard sheet sizes of 4' × 8' (1219mm × 2438mm).
