Purpose:

This guide helps with designing and constructing residential wall assemblies that meet R-22 or higher thermal performance in British Columbia. It applies to low-rise detached and semi-detached homes, rowhouses/townhomes, and multi-unit residential buildings up to six storeys. Topics include wood-frame, steel stud, concrete, and below-grade wall systems. The third edition adds guidance on acoustical performance, fire risk considerations, and embodied carbon reduction. A coil-bound print-on-demand version will soon be available for purchase from The Crown Publications Bookstore.
