Understanding Insulation Ratings and R-Values

Insulation is given an R-value which represents the thermal resistance to conductive heat flow. If your home’s current insulation has a low R-value, then you are likely losing money each time you pay your energy bill. Improved insulation in your home is the best way to help save on energy costs.
