Soundproofing spray foam insulation in Leduc has a cause no other city on this site has. Aircraft noise arrives from overhead, and that single fact changes what can and cannot be done about it in a way that is worth being honest about before anybody spends money.
Noise from above is different from noise from the side
Every other source people ask about arrives more or less horizontally, which is why fences, hedges, neighbouring buildings and distance all help. Overflight does none of that. It comes down onto the roof and the upper storey, so the ground-level mitigations that work for a road do nothing at all, and the surfaces that matter are the roof, the ceiling and the upper walls rather than the fence line. That is the first thing to establish, because it redirects the entire budget.
The roof and ceiling plane are where the work goes
On a house under an approach path the ceiling of the upper floor is the surface taking the load, and in most houses it is also the least substantial thing in the building: a layer of drywall with a vented space above it. Filling and sealing that assembly is what makes a difference, and it is frequently more effective than anything that can be done to a wall. It also happens to be work that improves the thermal performance at the same time, which is unusual and worth pointing out.
What can honestly be promised
Reduction, not removal. Aircraft noise carries a great deal of low frequency energy, and low frequencies pass through building assemblies far more readily than high ones do, which is why a distant aircraft is felt as much as heard. The work makes a real and noticeable difference to the sharper part of the sound and much less to the rumble underneath it. Anybody promising silence on a Leduc house is not being straight with you.
Open cell is the product, and the roof plane is the surface
For acoustic work the softer open cell material is the correct choice, because its structure absorbs airborne sound where the denser closed cell product used for nearly every other job on this site reflects it. Put that product into the assembly that is actually taking the noise, which on a house under an approach path is the ceiling and the roof plane rather than a wall, and the two decisions reinforce each other. A contractor reaching for their usual product and applying it to a wall is doing neither half of that correctly, whatever the quote says.
Soundproofing Spray Foam Insulation Leduc: Common Questions
Would a fence or trees help with aircraft noise? No. It arrives from above, so ground-level mitigation does nothing. The roof and ceiling are the surfaces that matter.
Can it be stopped completely? No. It can be reduced noticeably. The low frequency part passes through assemblies and cannot be removed.
Which product? Open cell, because it absorbs rather than reflects. It is not what is used for most other work here.
What if the wall stays open? Then it is not finished. Foam left exposed in a Leduc room does not meet the thermal barrier requirement and the wall has to be closed.
