Brooks anchors southeast Alberta's irrigation belt - an agri-food city with a diverse workforce and a climate of real extremes: hot, dry summers and cold, windy winters. About 62% of its homes predate 1991, so most spray foam jobs seal older stock, and the value runs both ways here: the air-seal that keeps heat in through winter also keeps the summer heat out.
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. - Attic R-38 is about 6" closed-cell or 11" open-cell. - Access and prep change labour on an older home versus an open build.
Why extremes make the envelope pay twice
Brooks swings from hot summers to cold, windy winters, so a sealed envelope earns in both seasons - stopping winter heat loss and summer heat gain. On the older, workforce-heavy housing stock, that year-round return makes the retrofit case strong.
