Ceramic Fiber Insulation, 1" Thick x 16" x 100", 2400F Fireproof Insulation Blanket, 3027E

Ceramic Fiber Insulation 2400 Fahrenheit Rated 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 ℉.
