Ultra-Thin Rigid Millboard Insulation Sheets for Furnaces
Thinner than most rigid insulation for furnaces and other high-heat applications, these millboard sheets are also used for gasket fabrication. Insulation performs best at temperatures above 1000° F.
Insulation Fill
- Max. Temperature: 800° F
- Heat Flow Rate: 0.27 Btu @ 75° F
- Density: 4 lbs./cu. ft.
- Color: Gray
- Specifications Met: ASTM E84 0/5 for Flame and Smoke
Small puffs of loose-fill insulation can be packed as densely as you choose. Pour or blow it into walls and ceilings, or mix it into insulating cements as a filler. The mineral wool fibers are treated to minimize dust.
