What is the thermal resistance for ETHAFOAM™ products?

Dow publishes thermal conductivity values for ETHAFOAM polyethylene foam products in Technical Data Sheets. To determine the thermal resistance (or “R Value”) for any given product, divide the foam thickness in meters (or inches) by the thermal conductivity in W/m.K (or BTU-in/hr-ft2-°F). For standard ETHAFOAM products with a thermal conductivity of around 0.06 W/m.K (0.4 BTU-in/hr-ft2-°F), this results in a thermal resistance (or “R-value”) of approximately 1.0 R per centimeter of thickness (2.5 R per inch of thickness), (R = hr-ft2-°F/BTU). See the Technical Data Sheet of your product of particular interest for a more precise calculation.
