About Selecting Thermal Insulation

High-Temperature Ceramic Fiber Pipe Insulation

Shield against extreme heat with these flexible ceramic strips. They are often used to insulate hose, cables, and process piping.

Insulation with adhesive backing allows you to install without having to hold in place. Secure with band clamps or other parts of the assembly once in position. Apply while cool. Adhesive will start to wear off around 400° F, but this does not affect the insulation’s temperature rating.
