Myths and Realities of Thermal Bridging

from Angie Tennyson

As part of the Building, Ecology, Science and Technology (B.E.S.T.) Lecture Series, Mark Lawton, Vice President and Senior Building Science Specialist at Morrison Hershfield presented “Myths and Realities of Thermal Bridging” at the University of Toronto, John H. Daniels Faculty of Architecture, Landscape, and on February 28, 2013.

In this lecture, Mark speaks about his latest ASHRAE sponsored research project entitled “Thermal Performance of Building Envelope Details for Mid- and High-Rise Buildings” (1365-RP). It is worth your time.

Mark provides an informative presentation on their research, and tools for measuring thermal bridges. With this knowledge, decisions on where to focus efforts and investments can be more easily made. We can debunk the myths and see the reality of thermal bridging’s ‘impact to the whole building and overall energy performance. We can improve the envelope performance, increase occupant comfort and moisture management. Thank you to Ontario Association of Architects (OAA) and Tremco Roofing for sponsoring and making this lecture series possible.


The video is the entire lecture, and starts a little low on the speaker, yet stick with it- finally when Ted Kesik mentions Thermal Breaks, you get the full picture.
