Calgary asks two different things of a spray foam job depending on what's being insulated. A house in an older SW or NE quadrant needs the chinook-driven freeze-thaw problem solved at the attic, rim joist and basement. A metal-clad shop or warehouse in Foothills, Manchester or Shepard Industrial needs the condensation-on-steel problem solved at the roof deck and wall panels. Same material, two very different jobs - and Calgary has a lot of both.
Every building type, one city
- Homes - about half of Calgary's housing predates 1991, concentrated in the inner city and established quadrants; that stock leaks at rim joists, basements and additions. See residential spray foam in Calgary and attic spray foam in Calgary.
- Commercial and industrial - warehouses, metal buildings and retrofits across Calgary's industrial parks. See commercial spray foam in Calgary.
- Farms, shops and acreages on Calgary's edges - see agricultural spray foam and shop spray foam province-wide.
Closed-cell or open-cell for a Calgary job
Below-grade, exterior and anything exposed to Calgary's chinook-driven moisture swings calls for closed-cell - it resists water and becomes a vapour barrier at about two inches. Open-cell is the lower-cost choice for interior walls and sound control where moisture isn't a factor. Most real Calgary jobs end up using both, matched room by room.
