Steel studs have been used quite successfully in the construction of interior partitions and are now being offered as an alternative to wood studs in exterior frame wall construction. In addition to its structural performance, the major consideration in the acceptance of an exterior steel frame wall for use in cold-weather regions is its thermal performance. As it was questionable whether existing calculation methods could predict the thermal performance of this type of wall, a laboratory investigation was undertaken to define the performance of steel frame walls and to determine the effect of some of the design features on their thermal performance. The results of the investigation were also used to check whether the calculation method outlined in ASHRAE HANDBOOK OF FUNDAMENTALS of the American Society of Heating, Refrigerating and Air-Conditioning Engineers was adequate for evaluating walls that have high-conductance framing members bridging a layer of air-permeable insulation, and that experience convective heat exchange between the framing members and the air in the insulated stud space.
