Strategies to Minimize Thermal Steel Bridging [G1]

Steel elements that bridge across the insulation in a building enclosure can cause significant heating and cooling energy loss--but they don't have to. There are several mitigation techniques that have been used in Europe, as well as other systems that are currently being developed. As buildings become tighter and more insulated, it becomes increasingly important to address thermal steel bridging. This seminar, presented by members of the Thermal Steel Bridging Task Committee -- a joint venture between the Structural Engineering Institute and AISC -- will explain the issue and present solution strategies. These include the use of manufactured structural thermal break assemblies, proprietary support systems, thermal "shims," isolation techniques, and others.
