Illustrated Guide – R30+ Effective Vaulted and Flat Roofs in Residential Construction in British ColumbiaView Saved (0)
This Illustrated Guide consolidates information on vaulted water-shedding roofs and flat waterproof membrane roofs that are capable of meeting R-30 or greater effective thermal performance when used on low- and mid-rise wood-frame buildings. The guide is intended to be an industry, utility, and government resource with respect to meeting this thermal performance level, while not compromising other aspects of building enclosure performance, including moisture management, air leakage, and durability.
Impact:This illustrated guide will be a reliable industry resource to educate designers and builders on the pros and cons of different design strategies for roof assemblies which achieve an effective R-30 value or higher.
