Any contractors out there who have been succesful in soundproofing a brick party wall in a semi detached home?

The stairs run along it so building studs and adding insulation is not an option. We can spare an inch or so, but not more.

Any sucess with using Quiet Rock, Green Glue or acoustic panelling? Blowing Insulation between the joists?

Thank you.

Hi Tania,

We have done many similar jobs like yours. The trick is to isolate as much of the vibration transferring from one side of the wall to your side. this is normally done by building a steel stud wall that only connects at the bottom and the top of the new wall, line with sound insulation and apply the Quiet Rock. In your case, it may be possible to attach steel fir channels to do some of the work, and attach in only a few places, then apply some sound batt and Quiet Rock. Perhaps it would be best to leave this to an expert, I suggest you have one or two come in to see it in person.

Hope this helps,

Andrew Parker

Hi Tanya Another way to effectively reduce sound transmission is with

lead sheathing. The product is about 1/64" thick and can be covered with drywall, it has the sound dampening qualities of a 6" concrete wall. The product is called Sheald and can be found at Canada Metal website

It is a Toronto based Company.

Is the dividing wall brick? or studs and drywall/plaster? Is there any sort of space in the wall that can be insulated. I have a product that can be injected into a cavity and works great at soundproofing. Its called airkrete. Its made as in injectable insulation, but has soundproofing qualities.

i think you are better off with double Quiet Rock installed on resilient bars. since you don't have lots of space.
