DOE's Insulation Fact Sheet

A new 20-page fact sheet on insulation, published by the U.S. Department of Energy, recommends that when steel framing is used for new construction, a layer of rigid foam sheathing be installed

in all U.S. climates. The

Insulation Fact Sheet includes a map of the U.S. showing nine different insulation zones, which factor in both climate and fuel costs. Recommended insulation levels for both new construction and remodeling are keyed to the map. An Internet version of the fact sheet is also available; just type in your zip code and find the recommended insulation levels: www.eren.doe.gov.
