Foil Vapor Barrier Insulation DPTF-1251 is a excellent vapor barrier & reflective insulation. Consists of 12μpolyester film/25 μ aluminum foil/12 μ polyester film.
Foil Vapor Barrier Insulation DPTF-1251 is a excellent vapor barrier & reflective insulation. Vapor barrier insulation consists of 12μpolyester film/25 μ aluminum foil/12 μ polyester film. Used as a facing over insulation board, segments, pipe section, etc.
Foil Vapor Barrier Insulation primarily used in cold/cryogenic insulation systems, to prevent the ingress of moisture into the insulation. It is excellent as radiant barriers, flame retardant and vapor barriers can reduce energy loss costs 5% to 10%.
Foil Vapor Barrier Insulation combines the excellent vapor barrier properties of aluminum with the outstanding mechanical and thermal characteristic of polyester film, giving a ideal, flexible and efficient barrier material, suitable for outdoor use.
