Polyurethane Foam Insulation Sheets with Perforated Facing
- Temperature Range: -20° to 200° F
- Heat Flow Rate: 0.3 Btu @ 75° F
- Density: 2 lbs./cu. ft.
- Color: Black
- Specifications Met: FMVSS-302
The perforated vinyl facing allows moisture to evaporate and resists cracking and fading. These flexible sheets are good for insulating large enclosures.
Acid-Resistant Silica Insulation Sheets for Furnaces
- Temperature Range: 0° to 2000° F
- Heat Flow Rate: 0.78 Btu @ 800° F
- Density: 10 lbs./cu. ft.
- Color: White
Commonly used in furnaces and engine compartments, these flexible silica fiber sheets resist corrosive acids. They perform best at temperatures above 1000° F.
Ceramic Fiber Insulation Sheets for Furnaces
- Temperature Range: See table
- Heat Flow Rate: See table
- Density: See table
- Color: White
- Specifications Met: See table
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.

Chemical-Resistant Cellular Glass Pipe Insulation
Very rigid with a 0% water absorption rate, this insulation is unaffected by corrosive environments, organic solvents, and most acids. It is typically used in chemical-processing systems and underground lines. Insulation is flame resistant, meeting ASTM E84 0/0 for flame and smoke. Seal with tape (sold separately). Outdoor and underground use require metal jacketing (sold separately).
- Temperature Range: -450° to 900° F
- Heat Flow Rate: 0.29 Btu @ 75° F
- Density: 7.5 lbs./cu. ft.
- Color: Black
- Specifications Met: ASTM C522 Grade 6, ASTM E84 0/0 for Flame and Smoke

Pipe Cradles for Loop Hangers
Also known as pipe shields, these cradles provide additional support and prevent insulation from tearing when routing insulated pipe through loop hangers.
Adhesive-mount cradles have an adhesive strip that attaches the cradle to the pipe’s insulation.

Strut-Mount Routing Saddles for Insulated Pipe
Clip these saddles around the outside of strut channel for a quick way to route insulated tubing and pipe. Curved edges on each end of the saddle protect insulation from abrasion if the pipe moves.
