Our 18 ounce Vermiculite insulation fabric is a high temperature resistant material woven from “E” glass fibers. They are coated with a base film of vermiculite and provide extended service temperatures up to 1500°F.
Vermiculite is a naturally occurring, micaceous hydrated magnesium-aluminum-silicate product. It is 100% asbestos free and inorganic. Within the vermiculite film exists microscopic, disc-shaped platelets that stack and overlap and these platelets are then embedded within the base fabric’s fiber bundles. Coated on the surface, these platelets then form an insulating film. The insulating film then acts as a very effective heat and flame barrier.
Standard and rigorous testing will confirm that the Vermiculite Insulation Fabric possesses a service temperature of 1500°F. At temperatures that are in excess of 1000°F, the vermiculite finish insulates the glass, and even at temps up to 1800°F, the insulation fabric will not melt or shrink! This ensures that this material will consistently perform as an effective heat and flame barrier. These vermiculite fabrics are odorless and virtually smokeless even under a direct flame.
