Humidity-Resistant Paper Insulation Sheets
- Temperature Range: 0° to 265° F
- Heat Flow Rate: See Table
- Density: See Table
- Color: Off-White
- Specifications Met: UL 94 V-0, UL 94 5VA
Often used in high-humidity applications for its low moisture absorption, this flexible paper insulation is made of inorganic materials. It’s typically used in appliances and electrical devices. Insulation meets UL 94 V-0 and UL 94 5VA for flame resistance.
Thermally Stable Composite Paper Insulation Sheets
- Max. Temperature: 1100° F
- Heat Flow Rate: 0.22 Btu @ 75° F
- Density: 8.7 lbs./cu. ft.

Made of flexible composite paper, these sheets won't shrink or lose shape in the high temperatures of air furnaces and hot water tanks.
Light-Absorbing Black-Out Paper
Block out stray and unwanted light. These sheets of black-out paper have a raised, velvet-like surface that absorbs light. Cut to size with scissors or a utility knife.
