Soundproofing spray foam insulation in Carstairs is asked about most often by households where somebody has stopped making the drive on some days and is now working from a room in a house that was never arranged for it.
A house that was never meant to hold a working day
These houses were built on the assumption that everybody left. The open plan that suits a family in the evening is the worst possible arrangement for somebody taking calls at eleven in the morning while the rest of the household is home. That is the situation behind most enquiries here, and it is why the useful question is which single room can be made quiet rather than how to quieten the house.
One room, treated properly, is the achievable goal
Treating a whole house is neither affordable nor necessary. What works is picking the room that has to be quiet, usually a spare bedroom or a basement room being used as an office, and dealing with its walls, its ceiling and its door properly. In a Carstairs house that is normally three or four surfaces rather than a project, and it produces a result somebody can actually rely on for a call.
The door is usually the weakest part of the room
People spend on the walls and leave a hollow interior door with a gap underneath it, which is the single largest path in most rooms. Sound follows air, and an undercut door is an open channel. Any sensible plan deals with the door and its perimeter, and doing that alone frequently delivers more than insulating one of the walls would. It is worth saying because it is the cheapest part of the job and the part most often skipped.
What the material contributes, and what it is covered with
Open cell fills the cavity completely and stays soft, which is what absorbs airborne sound, so it works well on voices and on general household noise from elsewhere in the building. It does much less for footsteps overhead, which travel through the structure. Where the foam goes into an occupied Carstairs room it is covered by a thermal barrier, which in practice is the drywall going back on, so the making good belongs in the quote. More on thermal barrier vs ignition barrier. It also does relatively little for low-frequency noise arriving through a floor or a party wall, which travels as vibration rather than as air. Saying that plainly before the work is what stops it disappointing, because the useful answers for that problem are mass and isolation rather than anything that goes into a cavity.
