Often used in high-humidity applications for its low moisture absorption, this flexible paper insulation is made of inorganic materials. It’s typically used in appliances and electrical devices.

The most common of our flexible high-temperature sheets, these are used to insulate furnaces.

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

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

The fiberglass facing on these flexible silicone foam sheets protects against highly abrasive conditions and resists tearing.

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

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.

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.

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

Typically used as duct wrap, these flexible sheets consist of polyethylene bubbles covered with aluminum polyester foil that prevent 96% of heat from radiating into or away from duct. Use on rectangular and round ductwork.

Wrap rectangular and round ductwork with this flexible insulation.
