- Specifications Met: ASTM E84 0/0 for Flame and Smoke
Also known as fire wrap, these flame-resistant sheets meet ASTM E84 0/0 for flame and smoke and create a fire barrier around rectangular and round ductwork. They are often used to wrap kitchen grease exhaust ducts and air ducts. Seal with reinforced HVAC tape (sold separately).
Heat-Reflecting Air Bubble Duct Insulation Sheets
- Temperature Range: -60° to 180° F
- Heat Flow Rate: Not Rated
- Density: Not Rated
- Color: Silver
- Specifications Met: ASTM E84 20/30 for Flame and Smoke
Typically used as duct wrap, these flexible sheets consist of polyethylene bubbles covered with aluminum polyester foil that prevent 96% of heat from radiating into or away from duct. Use on rectangular and round ductwork.
