About this product
800 Series Spin-Glas® duct and equipment insulation is manufactured from inorganic glass fibers bonded together with thermosetting resin. This rigid fiberglass board insulation is available plain or faced in a variety of densities for use on systems that operate up to 450°F (232°C). For faced products, surface temperature should not exceed 150°F (66°C). AP, FSK, or Ultra vapor retarder-faced material. Types 813, 814, 815 and 817 provide neat square corners for an excellent finished appearance on duct and equipment systems. Spin-Glas insulation can be readily cut with an ordinary knife and secured with mechanical fasteners and/or adhesives. Johns Manville 800 Series Spin-Glas® equipment and external duct insulation provides a broad range of solutions to meet your unique application needs. The breadth and depth of our product availability includes plain, FSK, AP (ASJ), or Ultra (poly-top) faced board, where the facing acts as a vapor retarder. You can be assured you are getting the same superior performance from the facing as the insulation because we manufacture both to the highest quality standards.
