Building Envelope Guide for Houses: Part 9 Residential Construction, Second Edition

 View Saved (0)


The updated Building Envelope Guide for Houses provides practical information related to the design and construction in accordance with Part 9 of the 2018 British Columbia Building Code (BCBC). This guide builds on the approaches presented in the first edition and has expanded to include alternate construction approaches such as Insulating Concrete Form (ICF) and conditioned attics. Further construction systems and installation details have also been added, including the improved energy performance of homes built to the increasing performance levels of the BC Step Code.


The guide describes minimum requirements for the building envelope for houses, including requirements for rainscreen in coastal areas, as well as building practices for the design and construction of wall assemblies that go beyond the minimum requirements of the Code for best practices.
