  • 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.
