Rigid Silica High-Efficiency Insulation Sheets for Furnaces
 |
Typically used in ovens and furnaces, these are the most efficient of our rigid high-temperature insulation sheets. Please note that they require special care when installing since the crumbly material is difficult to work with and will crack easily. Sheets lose strength over time and are intended to be installed behind another facing or insulation material. They resist damage from fire and moisture. Insulation performs best at temperatures above 1,000° F.
