Noise is a bigger subject in Canmore than in a town of comparable size, for a structural reason and a social one. Structurally, the newer two thirds of the housing is attached or stacked, so most residents share at least one wall or a floor. Socially, a good share of those neighbouring units turn over weekly and are occupied by people on holiday, who are leaving for a trailhead at five in the morning or coming back from dinner at eleven.
What foam does to sound, honestly
Open-cell foam is the acoustic product. At about R-3.5 to R-3.8 per inch it is a lighter, more open material than closed-cell, and that structure absorbs airborne sound inside a cavity rather than reflecting it back and forth. It is genuinely effective on voices, television, music and traffic. Closed-cell is dense and rigid, and while it seals superbly it is the wrong choice when the objective is acoustic - it can even couple two surfaces together more firmly than before.
And what it does not do
Foam is not mass and it is not a decoupler. Impact noise - footsteps on the floor above, a chair dragged across hardwood, a door slammed in the next unit - travels through the structure itself, and the only things that reduce it are added mass, resilient channel or a floating assembly. Any claim that a cavity full of foam will silence the unit upstairs is wrong, and we say so because the complaint we get called about most often in a stacked building is exactly that. Filling the cavity helps the airborne half and leaves the impact half for a different trade.
Sealing is half of airborne sound
Sound follows air. A shared wall with an unsealed electrical box, a gap at the top plate, a continuous void running up to the roof or a pipe chase passing through it will transmit conversation almost regardless of what is in the cavity, because the air path is a direct connection between two rooms. In attached Canmore buildings those paths are common and they are also the reason cooking smells travel between units. Sealing the penetrations often produces more audible improvement than filling the wall does, and it is the cheaper half.
Rooms worth treating in this town
The wall between a nightly rental unit and the one you live in, obviously. The floor under a bedroom where the unit above has a hard-surface floor. The wall between a bedroom and a shared entry stair, which carries every arrival and departure. And the mechanical room, because a heat recovery ventilator or a boiler that runs all winter in a small mountain home is a constant noise source that absorption handles well.
If you are building or renovating, say so early
Acoustic performance is far cheaper to buy during construction than to retrofit. While the framing is open there is the option to combine open-cell in the cavity with the mass and decoupling layers that handle impact, which together get a result neither can reach alone. Once the drywall is on, the realistic options narrow to sealing penetrations and whatever can be reached from one side. Tell us which stage you are at before anyone quotes.

Soundproofing Spray Foam Insulation Canmore: Common Questions
Which foam is used for sound? Open-cell. It absorbs airborne sound in the cavity. Closed-cell is the sealing and moisture product, not the acoustic one.
Will it stop footsteps from the unit above? No. That is impact noise through the structure, and it needs mass or a decoupled assembly. Foam handles the airborne half.
Our neighbour is a holiday rental. What helps most? Sealing the shared wall's penetrations first - boxes, top plate, chases - then filling the cavity. The air path is usually the loudest part.
How much does soundproofing spray foam insulation cost in Canmore? Priced per board foot of sprayed area, so the wall or floor area sets the number. Whether a finish has to come off to reach the cavity is the bigger variable.
How do I get a soundproofing spray foam insulation quote in Canmore? Describe the noise - voices, music, footsteps, a slamming door - and which surface it comes through. The description decides whether foam is even the right answer.
