R-value of foam insulation

Aug 1, 2023 · The performance of an insulation material largely depends on its R-value. R-value, or “resistance value,” is a measure of thermal resistance. It is a parameter that quantifies the ability of an insulation material to resist heat flow. The higher the R-value, the greater the insulating materials’ effectiveness.
