Can Steel Framing Be Used in High-Performance Houses?comments (4) January 24th, 2013 in Blogs
Planning a new house in the New York-New Jersey area, Sal Lombardo is weighing the relative merits of several construction methods. And on a list that includes double-stud walls, structural insulated panels, and other high-performance options is one that's bound to raise a few eyebrows: light-gauge steel framing.
Steel would seem to have plenty of benefits. Unlike dimensional lumber, it's dependably straight and true. It's light in weight, and priced competitively with wood. For framers used to wood, it will take some getting used to, but seasoned crews are fast and efficient, and off-cuts and other scraps are easy to recycle.
The problem is its conductivity: steel framing can transport a lot of heat in and out of a building. Thermal bridging is a far more significant problem with steel-framed buildings than it is with wood-framed structures.
The question Sal poses in the GreenBuildingAdvisor's Q&A forum is whether there's a way around this shortcoming that would let him take advantage of steel framing's many benefits.
That's the topic for this month's Q&A Spotlight.
