Manson Insulation Alley Wrap B Fiberglass Duct Wrap Insulation (FSK Foil Faced) is designed to reduce energy costs and provide temperature control. FSK foil-faced on one side ensures durability and protection from condensation. Suitable for rectangular or round ducts, it is the perfect choice for commercial or residential heating and air conditioning ducts.

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.
