ARK-W20

ARK-W20 is a high-performance Polyester/Scrim/Kraft (PSK) insulation facing engineered with a specialty Polyester layer that offers superior thermal stability compared to conventional PSK products. The multi-layer structure—Polyester, reinforced fiberglass scrim, and kraft paper—provides excellent tear resistance, reliable vapor control, and consistent performance across a wide temperature range. It is ideal for insulation in walls, ceilings, HVAC ducts, and general residential or commercial applications requiring enhanced moisture and air control.

Key Advantages:

  • Enhanced high-temperature resistance due to upgraded specialty polypropylene formulation
  • Reinforced fiberglass scrim delivers excellent tear strength and durability
  • Kraft layer provides consistent and reliable vapor barrier performance
  • Improved structural stability compared to standard PSK facings on the market
  • Lightweight and easy to handle for faster and more efficient installation
