Multi-family spray foam insulation in Cochrane is nearly all attached housing rather than apartment blocks. The town has grown through townhouse and duplex phases, and those rows are built along terraces cut into the hillsides, which produces something the flat-lot versions of the same product never do.
A row stepped down a slope has no typical unit
On level ground the units in a row are interchangeable and what is true of one is true of all of them. Step that row down a graded terrace and the end units sit at different elevations, the lower level of one is beside the garage of the next, and the amount of wall that is above grade changes as you walk along it. An owner or a board pricing work from one unit's experience will get it wrong, because the unit that complains is usually the one with the most exposed wall rather than the one that represents the row.
The end unit at the low end of the row
Two things stack on that unit. It has an exposed side wall where the interior units have a neighbour on both sides, and it sits where cold air running down the slope collects. It is reliably the unit with the complaints and reliably the one worth treating first, and saying so plainly is more useful to a board than proposing the whole row at once.
Attached does not mean the neighbour is the problem
When a complaint is about noise, it is worth separating what insulation can address from what it cannot. Sound arriving through the party wall as airborne noise responds to filling and sealing that assembly. Footsteps and doors travel through the structure and do not. That distinction gets made before anything is quoted, because a party wall treated for the wrong problem is money spent without the complaint going away.
Who decides, and what a board can actually approve
These rows are typically run by a condominium board working to a reserve schedule and a budget that was set before anyone in Cochrane asked about envelope work. What tends to be approvable is a defined scope with a visible result on the units that are complaining, rather than a whole-property programme. Starting with the exposed end units gives a board something it can decide on and something it can point at afterwards.
Multi-family Spray Foam Insulation Cochrane: Common Questions
Why is one unit in our row so much worse than the others? On a stepped row the end unit at the low end has more exposed wall and sits where cold air collects.
Will this stop us hearing the neighbours? Partly. It helps with airborne sound through the party wall and does nothing about footsteps through the structure.
Does the whole property have to be done at once? No, and usually it should not be. The exposed end units are where a first phase does the most.

After the foam: the interior finish
Once the foam is in and trimmed, the assembly needs its interior finish, and on an occupied space that finish is also the code-required thermal barrier over the foam. We work alongside drywall finishing in Cochrane, an independent drywall contractor, so the two stages are not left to collide on site.
