Also known as Macor, these glass-mica ceramic sheets and bars withstand temperatures up to 1470° F.

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

The most common and easiest to work with of our rigid high-temperature insulation sheets, these are often used in furnaces.

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.
