Brooks homes deal with an Alberta climate of extremes - hot summers, and cold winters driven by the wind that sweeps southeast Alberta. With roughly 62% of the stock built before 1991, most homes here leak in both directions: losing heat in winter and gaining it in summer. Spray foam's air-seal is a year-round fix, not just a winter one. Residential spray foam insulation in Brooks has to hold up at both ends of that range rather than being tuned for winter alone.
Where Brooks homes lose heat (and gain it)
- Basements - closed-cell for R and condensation control against the ground.
- Rim joists - the leakiest band, and a fast win.
- Attics - where summer heat pours in and winter heat escapes; sealing cuts both.
Why the air-seal works both seasons
An air-sealed envelope stops the wind-driven infiltration that costs you in a Brooks winter and the heat gain that runs the AC in July. Batt slows heat one way; foam seals the air both ways. For an older Brooks home, that's comfort in every season.
Which density for a Brooks house
Per assembly, not per house. 2 lb closed cell handles below-grade and moisture-exposed work - basement walls, crawl spaces, rim joists - at roughly R-6 to R-7 per inch, and is its own vapour barrier at about two inches. Half pound open cell suits interior walls and sound. Most homes here use both.
What a retrofit actually involves
Foam goes into whatever is open. In an occupied Brooks home that usually means the basement header and rim joist first - reachable without opening finished walls, and where the largest air leak normally sits. Attics next. Walls only when a renovation has already opened them. Occupied-space foam gets the code thermal barrier.
Manufactured and older homes, and where they lose heat
The housing mix here includes a substantial number of manufactured and older homes, and both lose heat in ways that differ from a standard stick-built house. A manufactured home has a belly and skirting rather than a foundation, so the underside is the largest exposed surface and the plumbing frequently runs through it. Sealing and insulating that space is a freeze-risk question as much as a comfort one. Older stick-built homes here tend to have shallow wall cavities and little or no deliberate air barrier, which means air movement rather than insulation depth is the limiting factor. In both cases the useful first question is where the air is getting in rather than how much insulation is present.
Residential Spray Foam Insulation Brooks: Common Questions
Will it fix a cold floor? Usually - a cold floor is an air-leak problem before it is an R-value problem, and closed cell fixes both.
Can it go over existing insulation? No. Foam bonds to the substrate, so what is there comes out first, and that removal belongs in the quote.
