Advanced aluminum laminated barrier for superior vapor-proof and thermal performance
POLYTECH Vapor Barrier has very good reflective function because of its aluminum laminated layer. The Aluminum layer makes the vapor barrier not only good at vapor-proof, but also provides excellent heat resistance and warm-keeping properties. The strong woven structure inside gives the barrier much better tensile and tearing strength.
Compared to one side aluminum vapour barrier, the double side laminated barrier has better heat resistance, making it very suitable for use under hot environments and in special steel constructions.
Reflects radiant heat, reducing cooling costs in summer and retaining warmth in winter.
Prevents moisture penetration, protecting structures from mold and water damage.
Reinforced woven structure provides exceptional tensile and tear resistance.
