    Ceramic Fiber Insulation Sheets for Furnaces

    Image of Product. Front orientation. Insulation Sheets. Ceramic Fiber Insulation Sheets for Furnaces.
    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 1,000° F.
    Without Binder—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.
