What is R-value? What does it mean?

R-value refers to how effective insulation is at stopping heat transfer. The higher the R-value, the better! R-value depends on a few things, including the material, thickness and density of the insulation. To achieve the highest possible R-value and to get the most out of your insulation, it’s important you insulate correctly – improper insulation installation can completely debunk your home energy efficiency efforts!
