Vapor barrier & insulation DPTF-1251 is an excellent vapor barrier & reflective insulation. It consists of 12μpolyester film/25 μ aluminum foil/12 μ polyester film. Used as a facing over insulation board, segments, pipe section, etc.

Reflective aluminum foil insulation radiant barriers are installed outside the Glass wool, Rock wool, mineral wool, foam insulation materials.Primarily used in cold/cryogenic insulation systems, to prevent the ingress of moisture into the insulation.Primarily used in cold/cryogenic insulation systems, to prevent the ingress of moisture into the insulation.

Vapor barrier & insulation DPTF-1251 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.
