Soundproofing spray foam insulation in Hinton runs into a decision most towns can avoid: sound work and thermal work want the same cavity and the same open wall, and at this elevation the thermal job has the stronger claim on it, so the honest conversation is which one a particular wall is doing.
The two jobs want different products in the same space
Open cell foam is soft, fills a cavity completely and absorbs sound. Closed cell is dense, resists moisture movement and is what an exterior assembly under a long continuous load wants. They are not interchangeable and they cannot both occupy the same bay. That is the whole tension, and it is resolved by asking which surface a wall actually is rather than by trying to buy both.
Interior walls are yours to use for sound, exterior ones are not
This is the rule that settles nearly every case here. A partition between two rooms has no thermal job at all, so it can be given entirely to sound. An exterior wall has a job that runs for six months of the year and it should not be compromised for a quieter room. Where a Hinton household wants a quiet bedroom on an exterior wall, the answer is the interior partitions, the floor and the door, and the exterior wall stays a thermal assembly.
The floor between levels is where the result actually comes from
People ask about walls and the sound is usually arriving through the floor: along the joist cavity from the room below, and along the duct runs sharing that cavity. Neither of those is an exterior surface, so neither competes with anything, which is what makes the floor the strongest value available on this subject. It is also reachable while a basement ceiling is open, which is when most of these jobs are sensibly done, and it is work that never has to be revisited once the ceiling goes back up.
The heating runs for a much larger share of the year here
Equipment noise is a bigger part of the household soundscape in this town than in a milder one, for the simple reason that the system is running far more of the time. A furnace cycling, a fan starting, and ducts expanding as they warm are all sounds that a southern house hears in bursts and a Hinton house hears from October to May. Where that is the complaint, the useful work is around the mechanical space and the first few metres of duct rather than anywhere in the room being disturbed, and it is worth establishing which of the two is actually happening before any wall is opened.
Soundproofing Spray Foam Insulation Hinton: The Covering Requirement
Open cell foam is what is used where sound is the objective, and wherever it goes into an occupied Hinton room it is covered by a thermal barrier, which in practice is the drywall going back on. That belongs in the price from the start. It also means that if a wall is being opened anyway, the decision about which job it is doing has to be made before it is closed, because reopening it later pays the covering twice.

Soundproofing Spray Foam Insulation Hinton: Common Questions
Can one wall do both jobs? No. The products are different and only one fits the cavity. The wall gets assigned to one of them.
Which walls can we use for sound? Interior partitions, freely. An exterior wall has a job here that runs for half the year.
What helps most? The floor between levels and the ducts in it, and neither competes with the thermal work.
