Builders’ Breakfast Webinar: A promising “hybrid approach” for cladding attachment of fully exterior insulated walls (Feb 2022)
About The Event
BACKGROUND
When talking to builders about locating all the thermal insulation outboard of the wall structure, there is a consensus that this wall configuration delivers a holistic outcome. Among all of its benefits, “maintaining the wall structure close to indoor temperature year around” appears to resonate the most with builders due to the elimination of the condensation risk on the structure; not only this translates to significantly less liability for builders, but it also provides end users with a solution that is durable, flexible, and forgiving to lack of perfection. But then, one may wonder, “how come this assembly has so far only had a small share in the construction market?”. When asked about the reasons, builders across BC shared legitimate concerns in response to high cost and installation challenges associated with the exterior insulation and the rainscreen cladding system.
Generally speaking, two approaches are mainly utilized in British Columbia for the cladding attachment of the exterior insulated wood-framed walls:
In addition to the items discussed above, both approaches require special considerations for exterior wall corners, around windows/doors, etc., to ensure sufficient back-up is available for fastening the trims and cladding.
SESSION OVERVIEW
Based on two recently completed fully exterior insulated wood-framed projects, this session is going to introduce a new “hybrid approach” for the attachment of the exterior insulation and rainscreen cladding system that incorporate:
The presented “hybrid approach” is developed via various interactive brainstorming sessions with builders and structural engineers of the two projects with the goal to address the high cost and installation challenges that, over the years, have kept the industry away from embracing the fully exterior insulated wall construction. The step-by-step of the design development and site installation process were documented with photos to assist in communicating the intent intuitively.
