    Manson Insulation Alley Wrap B is used as an external insulation on commercial or residential heating or air conditioning ducts. 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.
