Product Data Sheet Fiberglas Thermal Insulating Wool (TIW) Types 1-HP & II-HP Insulations surfaces by attaching with welded pins or studs and finishing with sheet metal or metal mesh and insulating cement, then canvassed and painted. Pins with speed washers or studs and nuts should be installed on 16" (400mm) (maximum) spacing and not more than 4" (100mm) from the edge of the insulation. The insulation is normally impaled over the pins or studs and the enclosing sheet metal or metal mesh secured to the same fasteners. Joints of the sheet metal finish are offset from joints of the insulation. For temperatures over 400F (204C), good insulation practice suggests double layer application, with overlapping the layers regardless of insulation type. Single layer installation of any type of insulation material requires good workmanship to minimize heat loss and hot spots at insulation joints. Fiberglas TIW Types I-HP and II-HP Insulations may be installed in either single or multiple layers at all temperatures up to 1,000F (538C). Maximum allowable thicknesses at that temperature: TIW Type I-HP, 8 " (216mm); TIW Type II-HP, 6" (152mm).

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/m2, multiply values by 3.15. To convert surface temperatures, use the formula: C = (F-32)/1.8.
