These durable sheets resist compression and are often used in oven and power-generating applications.

These lightweight flexible fiberglass sheets are typically used to insulate equipment and appliances.

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

Made of flexible composite paper, these sheets won't shrink or lose shape in the high temperatures of air furnaces and hot water tanks.

Even when subjected to heavy compression, these rigid polyimide sheets won't crack.

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.
