Edson sits on the Yellowhead corridor in west-central Alberta's foothills, a forestry and oil-and-gas town with an older housing base - about 66% built before 1991. Between the aging stock and the cold that comes with foothills elevation, most local spray foam jobs are retrofits that seal an old home against a real winter.
How the quote is built
Per board foot - area x thickness x foam type: - Closed-cell (R-6 to R-7, vapour barrier) for basements, rim joists and exterior - the foothills-cold default. - Attic R-38 is about 6" closed-cell or 11" open-cell. - A west-central service radius can factor into rural quotes.
Why Edson's profile favours retrofit
An older forestry-town home loses heat through leaky rim joists and basements, and the foothills climate keeps the heating season long. Sealing those leaks pays back over that season - the aging stock is where the return is.
