NettetR-Values An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on … NettetWhat is Insulation R-Value? R-value measures how well certain building insulation materials, such as foam insulation, can resist heat. The higher the R-value, the greater the performance of the insulation. Keep in mind that if insulation is compressed, the R-value will decrease. Which R-Value is Right For Your Home?
