Understanding Vapour Permeance and Condensation in Wall Assemblies
Polyethylene air/vapour barriers have been used for many decades in the walls of new Canadian homes. This research illustrates where polyethylene is appropriate for this use and where other vapour barrier materials might be preferable. It identifies situations in which performance could be improved, and provides information on general approaches to help mitigate performance concerns.
