A house loses heat everywhere at once, but not evenly - and the cold rooms, the high furnace bill and the damp basement corner usually trace back to a handful of specific weak points. Residential spray foam targets those points directly, because it seals air leaks and insulates in the same pass. This is the hub for the whole-home picture; each area below has its own detail page.
Where it goes in a home
- Attic - the highest-return fix in most Alberta homes; stops heat loss and ice damming.
- Basement - closed-cell controls the condensation that ruins framed-out basements.
- Crawlspace - seals the cold, damp floor under the house.
- Rim joist - the leakiest single band in most homes, and a fast win.
- Walls and garages - comfort and, for attached garages, an air-seal between the garage and living space.
What changes after
Homeowners tend to notice the same three things: rooms that finally hold temperature, a furnace that cycles less, and the disappearance of the drafts you'd stopped noticing. In Alberta's climate the air-seal matters as much as the R-value - batt insulation can carry a good R-number and still let the wind through the gaps around it.
The right foam, room by room
Not every space wants the same product. Closed-cell leads below grade and anywhere moisture is in play; open-cell fits interior walls and sound control. A good installer specs the mix instead of defaulting to the priciest option everywhere. Estimate your job, then get a free quote from a vetted Alberta installer.
