Ultra-High-Temperature Ceramic Fiber Pipe Insulation Strips

Calcium Aluminum Silicate

Ceramic Fiber

Withstands the highest temperatures of all our pipe insulation. Made of ceramic fiber, this insulation won't melt, sag, or degrade in extreme heat. It's often used in ovens, furnaces, steel mills, and other demanding environments.

Calcium Aluminum Silicate Ceramic Fiber—Strong and durable, this insulation stays in place for many years without degrading.

Adhesive Backing—Install insulation without having to hold it in place—simply position and secure it using band clamps or other components of the assembly. Apply while cool. Heat above 400° F starts to weaken the adhesive, but the insulation's temperature rating remains unaffected.
