Commonly used in furnaces and engine compartments, these flexible silica fiber sheets resist corrosive acids.

Wet these rigid sheets and they become formable. They can be molded multiple times until exposed to heat, which causes them to become rigid again.

Thinner than most rigid insulation for furnaces and other high-heat applications, these millboard sheets are also used for gasket fabrication.

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.
