Radiant Barriers and Reflective Insulation Systems
Double side insulation systems, as Radiant barriers and Reflective insulation work by reflecting radiant heat. D/S Reflective Aluminum foil Radiant barriers are installed outside the Glass wool, Rock wool, mineral wool, foam insulation materials. It is excellent as radiant barriers, flame retardant and vapor barriers can reduce energy loss costs 5% to 10%.
DPTF-1251 is an 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.
Primarily used in cold/cryogenic insulation systems, to prevent the ingress of moisture into the 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.
