Thermal bridging at brick ties

Insulation placed in the exterior air cavity between brick veneer and a backup wall is now common practice; however, accounting for the reduction in thermal performance as a result of thermal bridging at brick ties is not. As the building enclosure’s actual thermal performance becomes more important and integrated into the overall design of other building systems, a clear understanding of thermal bridging and its impact on effective R-values is needed. Brick ties are only one example of a thermal bridge in the building enclosure, but a close look at their significance illustrates how important it is to account for thermal bridging.

Staying current with Canada’s energy code

The efficiency of new buildings designed to meet the 2011 National Energy Code of Canada for Buildings (NECB) will be significantly better than that of most older structures. It replaces the 1997 Model National Energy Code for Buildings (MNECB), and will become a requirement in the adopting provinces and territories. Consequently, it is critical architects, specifiers, engineers, owners, and other members of a project team understand its requirements.
