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.

With 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.

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. Insulation performs best at temperatures above 1,000° F.

Ultra-High-Temperature Ceramic Fiber Pipe Insulation Strips

Withstands the highest temperatures of all our pipe insulation. Made of ceramic fiber, this insulation won't melt, sag, or degrade in extreme heat. It's often used in ovens, furnaces, steel mills, and other demanding environments.

Alkaline Earth Silicate Ceramic Fiber with Foil Jacket—Withstands temperatures up to 2100° F. A foil jacket protects against dirt, dust, moisture, and minor scuffs. Its surface also reflects heat to keep temperature loss from pipes to a minimum.

Calcium Aluminum Silicate Ceramic Fiber—Strong and durable, this insulation stays in place for many years without degrading.

Ceramic Alumina Fiber—Handles higher heat and keeps the temperature of your line steadier than our other ceramic fiber insulation. It's ideal for your hottest applications, such as steam reformers and furnace piping.

Adhesive Backing—Install insulation without having to hold it in place—simply position and secure it using band clamps or other components of the assembly. Apply while cool. Heat above 400° F starts to weaken the adhesive, but the insulation's temperature rating remains unaffected.

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. Insulation is flame resistant, meeting ASTM E84 0/0 for flame and smoke. It performs best at temperatures above 1,000° F.

With Binder—Sheet with binder is easier to handle at room temperature than sheet without a binder, but it contains a small amount of organic material that burns off and releases smoke at around 400° F.

Without Binder—Sheet without binder won't produce smoke when heated.

Wet-Location Ceiling Tiles

Prevent your ceiling from sagging in high humidity conditions. Made from a blend of ceramic and mineral fiber, these tiles have excellent resistance to moisture, making them great for labs, food prep spaces, and even areas with standing water. They’re also treated to prevent the growth of bacteria, mold, and mildew. A fine fissured texture gives these tiles a dotted, nondirectional pattern. Install them in any direction to help you cut down on installation time and scrap material.
