Program Purpose:

Conventional light gauge steel framing has solid steel webs, which result in significant thermal bridging energyx000D
losses, or gains, in building walls. Structawire Corp (SWC) has devised a new steel framing stud where thex000D
solid web is replaced with a double wire truss that is resistance welded to two flanges. Heat transmissionx000D
through this innovative stud is reduced by 80 to 85%. However, in preliminary testing, it has been discoveredx000D
that the actual heat flows are lower than predicted by modeling and calculations. The hypothesis for thisx000D
difference is that resistance to heat flow through the weld points is greater than expected. The UBC teamx000D
worked with SWC and successfully constructed a thermal conductivity apparatus and this Engage plus grantx000D
will aim to further test samples from SWC. Through understanding the thermal properties of the weld points,x000D
optimized steel framing stud can be built.
