High temperature stability: Ceramic fiber 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 ceramic fiber that has high insulating value, strength durability. Made in the USA. 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.
