It is suitable for the exterior of rectangular or round sheet metal ducts and spaces, or surfaces where temperature and condensation must be controlled. Alley Wrap B fiberglass blanket insulation is a thermal and acoustical insulation product made from highly resilient, inorganic glass fibers bonded by a thermosetting resin. This product comes with a multi-purpose foil-scrim kraft (FSK) jacket. Vapor retarders have a 2" (51 mm) stapling flange on one edge and the factory-applied facing assures uniform quality. These fiberglass duct wrap insulation rolls are GREENGUARD (/GREENGUARD GOLD) certified and come with ECOSE technology, which utilizes a formaldehyde-free, plant based sustainable “binder” that gives the product its shape and brown color.
