Provides an outstanding barrier that reduces water vapor transmission to practically zero. Aluminum foil has been laminated between 2 layers of Polyester film, thus preventing the ingress of vapor moisture, salt spray, corrosion, oxidization, chemical reactions, oils, greases, and other causticity damage.
Applicable to polyurethane, polyisocyanurate, phenolic, cellular glass, nitrile rubber, polystyrene, urethane as secondary vapor barrier, but can be used as primary vapor barrier under a protective jacketing for cryogenic, low temperature, cold storage, petrochemical projects, and specialty industries including liquefied natural gas (LNG), liquefied petroleum gas (LPG), ammonia, ethylene, butane, propane, methanol, LN2, etc. Specify for replacement for mastics, rubber sheeting, glass cloth, and other interior and exterior jacketing materials.
