Building With Steel Framing

Posted on May 05,2015 by ScottG in light-gauge steel

Sal Lombardo is planning a new home in the New York-New Jersey area (Climate Zone 5) and is looking at a long list of high-performance construction options: double-stud walls, structural insulated panels, insulating concrete forms, Larsen trusses, and walls built with light-gauge steel framing. Wait a minute. Steel framing, as in the stuff that leaks heat through the building envelope like a proverbial sieve? Maybe, Lombardo says, it deserves another look.

Thermal Bridging

Posted on May 05,2015 by Peterbilt in steel framing

Everything is relative — especially when it comes to thermal bridging. Thermal bridging occurs wherever assembly components with low R-values relative to surrounding materials span from the inside to the outside of a building assembly. Thermal bridging takes place in wood-framed assemblies because, although wood is a pretty good insulator at about R-1 per inch, it is at least three times more thermally conductive than any cavity insulation, which start at about R-3.5 per inch.
