Whistler Home Exterior Insulation


A while back I posted a piece on The Evolution of a High Performance Luxury Home. Here is a second post on another project we are currently working on that is also an impressive home from both an architectural perspective as well as a sustainable energy efficient angle. I will follow up over the next few weeks with some additional high-performance features in additional posts.

This home will be a showpiece for us at RDC. Located in one of Whistler’s most scenic neighbourhoods, with panoramic views of Whistler Blackcomb and overlooking the beautiful Whistler Golf course, this home is true to RDC’s commitment to healthy sustainable high-performance standards with a modelled Energuide rating of 87.

One of the features of this home that will soon be covered up is the Owens Corning FOAMULAR CodeBord exterior insulation. This is key to the overall energy performance. While this is a new insulation strategy for us at RDC, it is a proven insulation system that has been widely adopted by builders in eastern Canada and the USA.

Our introduction to exterior insulation was made through our participation in the Local Energy Efficiency Partnerships (LEEP) program in the Lower Mainland of British Columbia. LEEP is an initiative out of Natural Resources Canada (NRCAN) and was sponsored in the Lower Mainland by The Home Owner Protection Office (HPO), BC Hydro, Fortis BC, the City of Vancouver, and the City of New Westminster. (See my blog post from earlier this year if you are interested in learning more about this valuable NRCAN initiative)

Owens Corning was one of the LEEP presenters and provided some great support to the builders who elected to use their CodeBord exterior insulation system on a new home.

The CodeBoard system helps us achieve our performance goals in the following ways:

  1. The 1.5 inches of exterior insulation improves the practical insulation value of our walls by over 30% and eliminates the thermal bridging from our 2X6 wood framing and other structural wall components;
  2. The Code Board also acts as our air barrier and becomes a more accessible, lower-cost way to hit our air tightness target of 1.5 ACH (or lower). The continuous rigid insulation with the overlapping edges and proprietary tape, along with some careful detailing around windows, doors and other holes, makes it much easier for the guys to seal up the home and get us to our target;
  3. This is the most economical way we have found to improve our adequate insulation numbers and economically hit our air change target;
  4. We also received excellent customer support from Owens Corning, including an onsite orientation for our staff.
