The most common of our flexible high-temperature sheets, these are used to insulate furnaces. They also can be fabricated into gaskets. Insulation performs best at temperatures above 1000° F.

Sheets without binder don’t have a binder that can burn when installed, so they won’t produce a strong odor. They’re often used to vacuum heat treat furnaces. However, they’re weaker and more brittle than sheets with a binder.

Sheets with binder are stronger in structure, easier to cut, and more pliable than those without a binder. The binder will burn out at 350° and release gas with a strong odor, so only use them in applications where burnout is not an issue.

Stronger than standard firebricks but with lower insulation capabilities, these withstand heavy abrasion on the floors and sides of furnaces. They meet ASTM standards for flame resistance. Also known as hard firebricks. Cut with a diamond-tipped tile saw and install with firebrick bonding mortar (sold separately).

Often used in furnaces, these firebricks have been machined for a snug fit to minimize heat loss. They are flame resistant, meeting ASTM E84 0/0 for flame and smoke. Cut with a brick saw and install with the firebrick bonding mortar (sold separately).
