Building Smart with Insulating Walls and Roofs

May 16, 2019 @ 9:00 am - 12:00 pm


How do you attach cladding over exterior insulation? Do unvented roofs work? Is spray foam the solution?

Join the authors of BC Housing’s guide to R22+ effective walls and guide to R30+ effective roofs for a morning of learning about how to insulate wood-frame walls and roofs.

Presenters will discuss methods for building higher R-value assemblies to provide attendees with the information necessary to meet increasingly stringent energy code requirements. The presentation will focus on wood-frame assemblies for low-rise detached and semi-detached homes, row-houses/townhomes, and multi-unit residential buildings up to six storeys.

This event is being held in collaboration with Building and Safety Standards Branch, RCABC, City of Vancouver, City of New Westminster, City of North Vancouver, Canadian Wood Council, AIBC, ASTTBC, and CHBA BC.
