Fiberglass insulation is ideal for application in industrial heating and process equipment. Fiberglass insulation is manufactured from inorganic glass fibers bonded together with thermosetting resin. Fiberglass insulation can be used in plain or faced form. Faced Fiberglass insulation is designed for systems that operate below ambient temperatures where vapor barrier protection is required. Fiberglass is available in a variety of densities for use on systems which operate up to 450°F (232°C). For faced products, surface temperature should not exceed 150°F (66°C). It can be readily cut with an ordinary knife and secured utilizing mechanical fasteners and/or adhesives.
