If you are a designer or builder who wants to achieve a high-performing, durable Passive House building, you need to understand control layers. Control layers are materials and systems of materials that are specially designed, selected, and detailed to control water, vapour, and air. They are placed throughout the building, from the roof, walls, and floor to the below-grade enclosure assemblies, details, and interfaces. They consist of membranes and other materials typically described as air barriers, vapour barriers, and water-resistive barriers, or collectively as critical barriers.

Building Enclosure Control Layers –  Session 1 of 4 Part Series

Session 1 will introduce the concept of building enclosure control layers and provide examples from passive house buildings of air barrier systems, vapour retarders/barriers, and wall/roof water management. The session will also cover placement of vapour control with different types and varying thicknesses of insulation and water control for walls, including rainscreens and water-resistive barrier materials.


The instructor for this course will be Graham Finch.

Date: Friday November 18, 2022 from 10am – 12pm PDT
