Rocky Mountain House homes - and the acreages around them - face a colder, longer winter than the plains thanks to foothills elevation, and about 57% of the stock predates 1991. That mix of older homes and mountain-edge cold makes spray foam a strong fit: seal the leaks, and a home holds heat through a season that runs long here.
Where these homes lose heat
- Basements - closed-cell against the cold ground, plus condensation control.
- Rim joists - the leakiest band, common in the older town and acreage stock.
- Attics and additions - settled insulation exposed by the foothills cold.
- Acreage shops and outbuildings - a common rural add-on (see the shop page).
Why the air-seal matters at elevation
Colder, longer winters mean continuous heat loss through every gap. Spray foam's air-seal stops the infiltration a good R-number can't, keeping a Rocky Mountain House home warm through the extended season.
