Values are based on horizontal heat flow, vertical flat surface, 80 F ambient temperature, still air, weathered aluminum jacket. To convert heat loss values to W/m 2 , multiply values by 3.15. To convert surface temperatures, use the formula: C=(F-32) 1.8.

Can be installed directly on hot flat or curved surfaces. 2. Attach using welding pins or studs. 3. Pins with speed washers or studs and nuts should be installed on 12"x18" (300mmx450mm) centers. 4. The sheet metal or metal mesh is secured to the same fasteners. 5. Joints of sheet metal should be offset from the joints of the insulation. 6. Panels can be erected flush to heated surfaces or away from them and secured to buckstays or breeching and ductwork angle iron stiffeners. 7. Double-layer construction with staggered joints is recommended for temeratures over 400 F. 8. Install to a maximum of 6" (152mm) at all temperatures up to 850F, or 8" (203mm) at temperatures not over 650F
