Lethbridge has one of the older housing stocks in the province - about 59 percent of its homes were built before 1991 - and it also has wind. Soundproofing spray foam insulation in Lethbridge is usually asked for because of one of those two facts, and often both at once, because wind noise and heat loss come through the same gaps.
Wind is an air-path problem before it is a sound problem
A steady wind finds every unsealed penetration in an assembly, and what you hear is air moving through gaps. That is the part spray foam is genuinely good at, because it air seals and insulates in one pass. It is worth being precise, though: filling a cavity reduces airborne sound through that assembly. It does not turn a window into a quiet window, and glazing usually carries more of the load than the wall does.
Airborne against impact
Airborne noise - wind, traffic, voices, television - moves through air paths and through the panel vibrating, and insulation helps. Impact noise - footsteps, doors, plumbing - moves through the structure, and insulation does very little. That one needs decoupling. Any quote that does not begin by asking which you have is not worth much.
Where soundproofing spray foam insulation Lethbridge earns its place
- Older assemblies in the pre-1991 core, where sealing the air paths addresses draught, heat loss and wind noise together.
- Student and tenant housing near the university, where partitions between rooms are the complaint.
- Interior partitions and home offices during a renovation.
- Bonus rooms and newer builds in Riverstone, Copperwood, The Crossings and Garry Station, where the cavity is open and the fix is cheap to do properly.
Why open cell for sound
Half pound open cell is soft and porous, so sound energy entering it is absorbed as it travels through the cell structure. Two pound closed cell is rigid and dense, and rigid materials pass vibration on. Closed cell is the better insulator and the right product below grade against southern Alberta's ground conditions. For acoustics specifically, open cell is the product that does the work.
What we will not tell you
We will not tell you foam makes a room silent, and we will not quote it for footsteps. Foam bonds to the substrate, so existing insulation comes out first and that removal belongs in the quote. Foam in an occupied Lethbridge room is finished with the code thermal barrier.
Soundproofing Spray Foam Insulation Lethbridge: Common Questions
Will this cut the wind noise? The part of it coming through gaps and through the wall assembly, yes - that is air sealing doing the work. Windows and doors usually need their own attention.
Does it help between bedrooms in a rental? For airborne sound through a partition we can open, yes.
Can you spray it into a finished wall? No. The cavity has to be accessible, because foam bonds to what it is sprayed against.
