Thermal bridging occurs when there is a “short circuit” in the continuity of insulation and associated air/vapor barriers within the enclosure. Effects of thermal bridging include energy loss, condensation, occupant discomfort, freeze/thaw damage, and moisture/mold problems.
The International Building Code stipulates that the effective R-value of a wall and/or roof assembly must consider effects of thermal bridging to be representative of the assembly’s actual thermal performance. This presentation will focus on strategic practical measures to mitigate the transfer of thermal energy, which occurs via conduction at window fenestrations, structural framing, exterior wall cladding attachments, and other typical assembly locations.
