Air Barrier Detailing in Attached Housing: Compartmentalization

In this video, Building Knowledge Canada President Gord Cooke describes the construction techniques that make multi-family buildings better for everyone by ensuring that the party wall in multi-family dwellings is as airtight as an exterior wall.

The Mechanisms and Measurement of Air Leakage in Houses

Join Building Science Expert Trevor Trainor as he presents some simple hygrothermal modeling scenarios for standard walls across various Canadian climate zones. A bit of myth-busting along with some cautionary tales about building-to-minimum-code. A dive into why Poly as a VB (vapour barrier) is a poor choice in many regions of Canada—and the importance of vapour diffusion retarder technologies and products.

Airtightness Testing in Large Buildings

Demand for more airtight large buildings is growing. Discover whether airtightness testing in larger buildings is just a matter of scaling up the procedures for a family home or if there are significant differences.

Large Building Airtightness

Learn the science behind air tightness measurements, and what compartmentalization plays in large buildings and occupant health. Unintended consequences, lessons learned and what really happens when we don't pay attention to the numbers. Gord Cooke and Rob Johnston were joined by Scott Stevens, and provided great insights into this topic that is gaining importance and momentum.
