Exterior Rigid Foam on Double-Stud Walls Is a No-No - GreenBuildingAdvisor

Many green builders like double-stud walls. Double-stud walls use affordable and environmentally appropriate materials to achieve a high R-value. The classic double-stud wall is made up of two parallel 2x4 walls with a space between them. If the framers leave a 5-inch space between the two rows of studs, this type of wall provides room for 12 inches of insulation — for example, dense-packed cellulose, blown-in fiberglass, or mineral wool.
