Spray foam insulation in Lacombe is applied as a liquid that expands and sets, sealing an assembly and insulating it in the same pass. In this town the second of those matters more than it does almost anywhere else, because of how the older buildings were put together.
What the age of the housing changes about the work
A great many of the older houses here were balloon framed, which means the wall studs run in one piece from the sill plate to the roof with nothing crossing the cavity at each floor. The wall is a continuous vertical shaft from the basement to the attic. Air enters low, travels the full height of the building inside the wall where nobody can see it, and leaves at the top. That single fact changes what work is worth doing and, more importantly, the order it is done in.
Which is why sealing beats depth on this stock
On a house built that way, adding insulation to the attic floor does very little, because the problem is not heat conducting through a ceiling, it is air arriving at the top of an open wall cavity. Owners in Lacombe have frequently already paid for a top-up and seen nothing change. Closing the tops and bottoms of those cavities is the work that alters how the house behaves, and the depth is worth having second rather than first.
The main street is a different building stock again
Alongside the houses there is a commercial core that is genuinely old and genuinely intact, and those buildings are a separate problem: solid masonry rather than framed cavities, shared party walls, upper floors that have been little used for decades, and facades that cannot simply be altered. They are worth treating and they are not treated the same way as a house, which is why the commercial work here gets quoted from the inside.
Where a Lacombe budget does the most
For most owners of an older house the sequence that returns the most is the same: seal the band at the foundation, close the tops of the wall cavities at the attic, deal with the penetrations through the ceiling, then look at depth and at any addition with a shallow roof over it. That order costs less than the reverse and it is the one that changes what the house feels like. It also means a limited budget spent on the first two items is not wasted if the rest waits a year.
Spray Foam Insulation Lacombe: Common Questions
Why did adding attic insulation change nothing? On a balloon-framed house that is the expected result. Depth cannot reach air arriving from inside the walls.
Is our house one of those? Age is a strong hint and it gets confirmed by looking, not assumed. It changes the scope significantly.
Where should a limited budget go? The band at the foundation and the tops of the wall cavities, in that order.
