K-Wool is a strong, lightweight, flexible insulating material made from long ceramic fibers. The fibers are cross-locked through a unique forming process to produce a material with unexcelled handling strength. K-Wool is a resilient and highly efficient insulator having low heat storage capacity and complete resistance to thermal shock. K-Wool is unaffected by most chemicals, except hydrofluoric and phosphoric acids and concentrated alkalines. If wet by steam or water, thermal properties remain unaffected after drying. 

Ceramic Blanket has the same properties as K-Wool and is supplied in larger sheets.  Used to cover and insulate large boiler doors and large surfaces.  Sold in 24” and 48” widths.  Thicknesses available in 1/4”, 1/2”, 1”, 1-1/2” and 2”.
