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

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

Designed for fluctuating, high-temperature applications, these semi-rigid sheets are typically used in furnaces and fire protection applications. They experience very little shrinkage at high temperatures, but the brittle material can be somewhat difficult to work with.

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.

Made of rugged PVC foam, these rigid sheets absorb impact and restrict the absorption of water, air, and gas. Use in applications with operating temperatures below 32° F.
