Overview:

A more thermally efficient exterior wall assembly may require splitting the insulation – exterior insulation and insulation placed between the steel studs. A question that often arises is, “does my weather-resistive barrier need to be vapour permeable?”

Morrison Hershfield, Owens Corning, Northern Facades and 3M Canada Company have teamed up for a virtual event to explore how to design your energy-efficient walls to avoid condensation, as well as other practical topics such as continuous insulation, material compatibility and penetrations in self-adhesive membranes.
