Soundproofing requests in Fox Creek come with a particular reason attached. In a town working around a gas field, a significant number of people are sleeping at hours when everyone else is awake: night shift, early starts, a crew turning over in a shared house or a rental suite. Quiet at two in the afternoon is a harder requirement than quiet at two in the morning, and that is usually what is actually being asked for.
Open-cell is the material for sound, not closed-cell
This is the first thing to settle, because it is the opposite of what people expect. Closed-cell foam is dense, rigid and excellent at heat and vapour, and precisely because it is rigid it transmits sound reasonably well. Open-cell foam is soft and porous at roughly R-3.5 to R-3.8 per inch, it fills a cavity completely and it absorbs airborne sound within the cavity rather than conducting it across. For an interior partition where sound is the objective, open-cell is the right product and closed-cell is the wrong one.
Filling a cavity is only part of the answer
Sound travels three ways through a wall: through the air in the cavity, through the materials that connect one side to the other, and through any gap at all. Foam deals with the first. The second needs the two faces not to be rigidly tied together, which is a framing or a resilient channel question. The third is where most disappointment comes from: a wall that has been foamed and still passes sound almost always has a gap left at the floor, at the ceiling, around an electrical box, or through a shared duct run. One unsealed outlet undoes a great deal of material.
The flanking path is usually the ceiling
In a house or suite the partition rarely goes all the way up. It stops at the ceiling and the joist bays run straight over the top of it into the next room, so sound takes the route above the wall rather than through it. In a basement suite the same thing happens through the floor assembly. Any serious attempt at sound control deals with those crossings, and in a retrofit that often means working from the joist bay above rather than from the room complaining about the noise.
What is realistic in a retrofit
Worth saying plainly: an existing wall can be made substantially better, and it cannot be made silent. Low-frequency noise, footfall and anything structure-borne needs mass and decoupling, which are construction changes rather than insulation changes. What foam in the cavity plus a thorough seal reliably improves is speech, television, and the general airborne noise of another household's day happening while somebody is trying to sleep. For a shift worker that is usually the whole problem.
Where it also pays to use it
Open-cell in interior partitions is worth considering around a bathroom, a laundry and a mechanical room at the same time as a bedroom, because those are the sources rather than the destinations. In a shared or rental building the stairwell and the common wall are the two places where doing it once avoids doing it repeatedly.

Soundproofing Spray Foam Insulation Fox Creek: Common Questions
Which foam is for sound? Open-cell. It is soft and porous and absorbs airborne sound in the cavity. Closed-cell is rigid and is the wrong choice for this purpose.
Will a foamed wall be soundproof? It will be substantially better, not silent. Footfall and low-frequency noise need mass and decoupling, which are construction changes.
We foamed the wall and still hear next door. Why? Almost always a flanking path: a gap at the ceiling or floor, an outlet box, or the joist bays running over the top of the partition.
How much does soundproofing spray foam insulation cost in Fox Creek? It follows the cavity area and the depth, and the variable that matters is how many flanking paths have to be opened up and sealed as part of the work.
How do I choose a soundproofing spray foam contractor in Fox Creek? Ask which foam they are proposing and what they intend to do above the wall. If the answer is closed-cell and nothing above the ceiling, the wall will still pass sound.
