R-value is the most important aspect to take into consideration when selecting attic insulation. The thermal resistance of a substance is indicated by its R-value. R-values are measured in units per inch and vary from 2.0 to 8.0. The quality of the insulation increases with the R-value. The insulation's product package or product description will list the R-value. There are many commonly used insulation materials used in the attic. Visit our website to know more.
