WebAn R-value is, in short, a number that tells you how good a material is at resisting the flow of heat. If it resists the flow of heat well (has a high r-value) then it’s a good insulating material. For the purposes of insulating a building then the higher the R-value, the better. You could think of R-value as the ‘resistance value’.
