Fort McMurray sits in Alberta's far north, where winter is longer and colder than anywhere else on this list - and where a lot of the housing is relatively new, much of it rebuilt after the 2016 wildfire. That mix (extreme cold, newer stock) shapes a spray foam quote here: the job is usually about maximizing envelope performance against brutal cold rather than patching a century-old house.
How the quote is built
Per board foot - area x thickness x foam type: - Closed-cell (R-6 to R-7, vapour barrier) is the default for far-north basements, rim joists and exterior - deep frost demands it. - Attic R-38 is about 6 inches closed-cell or 11 inches open-cell; in this climate, going tight is worth it. - Location factors - a far-north service radius and haul can affect the number.
Why extreme cold changes the value
In a Fort McMurray winter, the gap between a code-minimum envelope and a foam-sealed one is dollars every single day for months. Even on newer homes in Timberlea, Thickwood or Parsons Creek, a genuine air-seal pays back over the long, deep heating season.
