Air/Vapour Barriers

Air/Vapour Barriers

Integral to the building envelope, air and vapour barriers must be of the highest quality and controlled in their application in order to prevent costly repairs and decay in the future. J.A. Macdonald applies only the best materials from trusted industry leaders such as Bakor, Dryvit and Owens Corning.

Our air and vapour barriers protect against the moisture accumulation that leads to mold, corrosion and decay. Applied well, these membranes prevent future building envelope repairs and health issues generated by mold.

We offer permeable and non-permeable systems to cover a variety of project materials and specifications. Our varied selection of air/vapour barrier systems includes rubberized, cold fluid-applied and self-adhered membranes.
