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.

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

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

Stronger than standard firebricks but with lower insulation capabilities, these withstand heavy abrasion on the floors and sides of furnaces. Also known as hard firebricks.

Machine complicated shapes and precision parts from these glass-mica ceramic sheets in a fraction of the time it would take using other types of fired ceramic.
