Soundproofing with Non-expanding Foam spray?

Wouldn't you still need to put a layer of ceiling to hide or cover the spraying foam? I thought the spongy type of insulation blocks noise better?

No, they retrofit it...they drill a few holes in the ceiling, stick a hose in there and spray

you might to talk to prince lumber to review ur options/spray foam might be the best option

I meant to say spray foam might NOT be the best option

As much as I like Prince lumber I do not believe they are the ones to ask. You need to talk to several sound proofing companies. From what I do know (I am no expert on this) nobody will say that it will 100% work. It might reduce the news anywhere from 60-80%.

I have spoken to a few soundproofing companies, but of course they will say it will work...was just curious if anyone has had any success with this. I guess it makes sense that it could work since it will fill every void in the ceiling.

I think prince lumber has some knowledgeable people and 1 or 2 manufacturers suggested I talk to them. They should be able to give you the pros/cons of each
