Critical Canadian Home Building Science | PART 7: The Great Canadian VAPOUR BARRIER controversy.

Do we still need “Vapour Barriers” made of polyethylene in high performance walls with continuous insulation and good air barrier detailing? The industry and codes continue to struggle with this question. Is it time to get rid of the term “Vapour Barrier” and start talking about “vapour control layers” or “vapour retarders”. What does the true science (field testing) tell us? What does hygrothermal modeling tell us? Join Andy Oding in discussion with building science expert Trevor Trainor for an entertaining and informative discussion.
