Made of high-strength calcium silicate, these durable sheets withstand high temperatures and are often used in power-generating applications.

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.

Insulate high-vacuum furnaces and other low-oxygen vacuum enclosures with these rigid sheets. They withstand higher temperatures when used in a vacuum and can be machined through sawing or drilling.

Use these sheets in operating temperatures below 32° F, such as cold-storage applications.
