Understanding R-Value

R-Value reflects how insulated your home is, do you understand it?

Understanding your homes R-Value

Insulation is rated by its R-value, which measures its thermal resistance or how well it holds back heat. The higher the R-value, the better. Bare concrete walls are about R-1, while attic insulation in newly-built Midwestern homes usually measures about R-44.

R-value is proportional to the insulation's thickness, but it also depends on the type of material and its density. The more air pockets an insulating product has, the higher the R-value. For example, R-38 attic insulation may be 12 inches of fiberglass batts, 10 inches of rock wool loose-fill or seven inches of expanding foam.
