About Selecting Thermal Insulation

Ceramic Fiber Insulation Sheets for Furnaces

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

Rigid Mineral Wool Insulation Sheets

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

Thermal-Shock-Resistant Ceramic
Fiber Insulation Sheets for Furnaces

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.

Fiberglass Insulation Sheets

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

Crack-Resistant Rigid Polyimide Insulation Sheets

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

Moldable Ceramic Insulation Sheets for Furnaces

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.

Acid-Resistant Silica Insulation Sheets for Furnaces

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

Rigid Graphite Insulation Sheets for Furnaces

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.

Abrasion-Resistant Rigid Calcium
Silicate Insulation Sheets

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

Graphite Insulation Sheets for Furnaces

Insulate high-vacuum furnaces and other low-oxygen vacuum enclosures with these flexible sheets.

Ultra-Thin Rigid Millboard
Insulation Sheets for Furnaces

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

Thermally Stable Composite Paper Insulation Sheets

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

Rigid Silica Ultra-Insulation Sheets for Furnaces

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.
