Lynn Manufacturing Kaowool Ceramic Fiber Insulation, 1" Thick x 12" x 24", 2400F Fireproof Insulation Blanket, 3023E

Fireproof:  Kaowool ceramic insulation blanket withstands direct flame, continuous use at 2200 ℉, intermittent use at 2400 ℉.   Above 2400 ℉ it will begin to shrink, become brittle and eventually melt at 3200 ℉.
Thermal conductivity:  The R-value is approximately 2.5 per inch.  For a 1000 ℉ hot face with 1" of insulation, expect the cold face of the insulation to be 220 ℉.
Installation: Mechanical fastening or high temperature adhesive such as sodium silicate, refractory cement or RTV silicone.
Quality: Made from premium 8lb density Cerablanket that has high insulating value, strength & durability.  Made in the USA by ISO 9001 certified Morgan Thermal Ceramics.
Chemical composition: 46% alumina, 54% silica and less than 1% impurities.
Uses:  Fireplace insert insulation, baffle blankets, wood stove insulation, kiln insulation, blacksmith forge, pizza ovens, brazing, soldering blanket, welding, pellet stove, chimney lining, furnace insulation, boiler, foundries, refractory wool , glass blowing, jewelry making, fireproof doors, fireplace insulation, muffler packing.
