A primary weakness of light-gauge steel framing for houses has been its severely compromised thermal integrity. In general, the simplest way to get a steel-framed wall to perform like a 2x6 wood-stud wall is to use 2x4 steel studs and add 2” (50 mm) of insulating foam sheathing. Now, researchers at Oak Ridge National Lab (ORNL) are seeking a... Read more
