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.
Rigid Mineral Wool Insulation Sheets



- Temperature Range: 0° to 1200° F
- Heat Flow Rate: See Table
- Density: 8 lbs./cu. ft.
- Color: Green
- Specifications Met: See Table
These durable sheets resist compression and are often used in oven and power-generating applications. To use outdoors, add metal jacketing.
Sheets with wire-mesh reinforcement withstand extreme shock and vibration.
Sheets with foil facing reflect heat. The foil facing is also known as foil scrim kraft (FSK).
Flame-resistant sheets meet ASTM E84 0/0 for flame and smoke.
