Soundproofing spray foam insulation in Camrose is mostly a conversion problem. A large old house divided into five or six rooms let separately has walls that were added long after the building went up, and those walls were built to divide space rather than to stop sound.
A house cut into rooms was never designed for it
The original walls in a house like this are substantial, but the ones that matter are the new ones: a stud partition run across what used to be a large room, frequently with nothing in the cavity at all, sometimes not even carried up to the structure above. Sound passes through those as though they were not there, and residents reasonably conclude the building is badly built when in fact the building is fine and the partition is the problem.
Whether the wall goes all the way up
This is the first thing to establish and it is regularly the whole answer. A partition that stops at a dropped ceiling leaves an open path over the top of it into the next room, and no amount of filling the wall below will change that. On a Camrose conversion it is common, it is invisible from inside the room, and it is checked before anything is quoted because it determines whether the job is worthwhile at all.
Two different noises, and only one of them is ours
Airborne sound travels through the air and reaches a room through gaps and thin assemblies. Impact sound is created in the structure, by footsteps on the floor above or a door being shut, and travels through framing. Spray foam works on the first and does very little about the second. In a house let by the room the complaint is frequently footsteps, and somebody should say so before money is spent.
The soft material is the one that absorbs
For sound the softer open cell material is correct, because its structure absorbs airborne noise where the denser closed cell product used for nearly everything else on this site reflects it. Where a partition is open for other work, filling and sealing it properly costs very little on top of what is already happening, and that is the moment to do it rather than as a separate project later. Once the wall is closed up again, foam in an occupied Camrose room is finished with a thermal barrier in the ordinary way, which on an interior partition is simply the drywall going back on.
Soundproofing Spray Foam Insulation Camrose: Common Questions
Why does a converted house have no sound separation? Usually the added partitions rather than the original walls, and the first question is whether they reach the structure above.
Will it stop footsteps from the room above? No. That is impact noise travelling through the structure rather than through the air.
Which product? Open cell, because it absorbs rather than reflects. It is not what is used for most other work here.
