Superior Moisture and Heat Control

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.

Double-Sided Option

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.

Characteristics

  • Lightweight: Easy to handle and install
  • Clean and Thin: Minimal impact on building dimensions
  • Flexibility: Conforms to various shapes and surfaces
  • Durability: Invariable if attacked repeatedly
  • Thermal Performance: Low thermal conductivity and superior heat insulation
  • Safety: Outstanding safety and environmentally friendly
  • Efficiency: Easy to install with high efficiency
  • Cost-Effective: Versatile application with excellent value

Applications

  • Roof, Wall, and Floor Insulation: For heat insulation and thermal insulation in all types of buildings
  • HVAC Systems: Shells of air conditioners and water heaters
  • Pipe Protection: Protective coatings for water pipes and ventilating pipes
  • Industrial Packaging: Machinery packing for protection during transport
  • Specialized Uses: Making ice packages for cold storage and transportation

Technical Advantages

Heat Resistance

Reflects radiant heat, reducing cooling costs in summer and retaining warmth in winter.

Moisture Barrier

Prevents moisture penetration, protecting structures from mold and water damage.

Strength

Reinforced woven structure provides exceptional tensile and tear resistance.
