Features

  • 7-layer EPE core insulation structure for superior durability
  • Low emittance foil surface (E=5%) reflects up to 95% of radiant heat
  • High tensile white woven outer layer for added strength and a clean aesthetic finish
  • Tear-proof and puncture-resistant design ensures long-lasting performance
  • Excellent for carports, barns, and metal buildings requiring a thermal break
  • Minimizes heat transfer and thermal bridging in metal structures
  • Will not delaminate - maintains integrity and stability over time
  • Suitable for hybrid installations with foam or fiberglass
  • Provides an impressive R-value when installed with airspace
  • All-weather resistant and corrosion-free for extended lifespan

  • R-values represent estimated and potential heat resistance for our insulation in the proposed application.
  • Actual performance depends on air film size, temperature, surface condition, and airflow direction (up, down, or horizontal).
  • Calculations are based on RIMA, AIRAH, ASHRAE, and ISO 6946 standards, following ASTM procedures for air film resistance.
  • When two air spaces are used, values assume still air conditions in both spaces.
  • For a full R-value assessment, please contact us directly or your nearest dealer.
