Provides an
outstanding barrier that reduces water vapor transmission to practically
zero. Aluminum foil has been laminated between 2 layers of Mylar (Polyester
film), thus preventing the ingress of vapor moisture, salt spray, corrosion,
oxidization, chemical reactions, oils, greases, and other causticity damage.
Applicable to foam glass,
cellular glass, nitrile rubber foam, mineral fiber, polyurethane, polystyrene,
polyisocyanurate, urethane, semi-rigid and rigid material insulations
as secondary vapor covering and jacketing for low temperature, cryogenic,
cold storage, petrochemical projects, and specialty industries including
ammonia, ethylene, butane, propane, methanol, oil, liquid natural gas
(LNG), liquid petroleum gas (LPG), LN2, etc. Specify for replacement for
mastics, rubber sheeting, glass cloth, and other interior and exterior
jacketing materials.
