Basement ceiling soundproofing...

Does anybody have experience using those brown sheets of soundproofing material from the big box store?

I was thinking of putting it between the joists in my open ceiling basement, then running sheetrock over it.

Any ideas/thoughts?

I've used it in walls under drywall and it certainly helps although it should be referred to as sound deadening not sound proofing. To do a better job of sound proofing you would have to mechanically seperate the drywall from the joists - pretty difficult to do.

Thanks Rockpro!

Also, what do you use to cut this stuff? And what do you use to adhere it to wood? I am guessing construction adhesive?

Thanks again.

It cuts with a standard sheetrock knife (you can use a handsaw if you don't mind dulling the saw). Use a few roofing nails or 1 1/4" drywall screws. Don't forget to use min. 1 5/8" screws if you apply drywall over it. Good luck

Well, I went ahead and installed some of the sheets. I just scored them like drywall with a utility knife and held up with roofing nails like you said...worked perfectly!

Thanks!

I am unfamiliar with the product you are talking about but you can hang drywall on Z channel to help reduce sound. You can also hang multiple layers of drywall. Mass = quiet
