Insulation R-Value Recommendations
The U.S. Department of Energy has recently upgraded insulation R-value recommendations.These recommendations were the result of studies of energy costs for both heating and cooling by zip code. The United States, as a result of this study, was divided into eight zones. There is a wide range of R-values for ceilings. These R-values range from R-49 in the coldest locations to R-30 in the warmest parts of our nation. All areas of the nation require a minimum R-19 for exterior walls and floors over unheated crawl spaces.
Owens Corning has an extensive web site geared to consumers with information on insulation. Go to "Insulating At a Glance" and check out the wealth of information.
