I have some 3.5" diameter water pipes inside one wall of my theater room and up near the 9' ceiling.... see pictures below. I thought I might wrap the pipes that will be hidden inside the soffit, but I'm not sure what material to use. As for the pipe in the 2X6 wall, I can either wrap the pipe or do a double studded wall and place drywall on the theater side of the 2X6 wall (first pic) and then do another 2x4 wall attached by a bracket or clip to the 2X6 wall. I would prefer not to do this, since I would rather keep that extra several inches. Do you think wrapping the pipes and then using DD GG would work? Also, I would appreciate any ideas on what to do with the pipes up near the ceiling (second pic... which will be covered by a soffit of some sort). Thanks!
I'd have you plumber replace them with cast iron pipes. I have a similar issue and decided not to replace them......due to cost.
They are very loud without the sheeting in, I am guessing they'll still be heard when the room is sealed
Thiat's not a viable option for me at this point. Fortunately, these particular drain pipes will not be used much, but I'd still like to take some reasonable steps to reduce some of the noise before building a soffit consisting of mdf and fiberglass, which is then covered by DD GG around the soffit.
Thanks BIGmouth! I just ordered some off of Amazon. You've been a tremendous help to me today! Is this the same thing you use around duct work... not that I'm there yet... just looking at some different alterantives.
It does work on duct work but as you've discovered it is pricey so I choose my spots carefully where I think it will be of benefit. Ted will tell you he generally feels a damped decoupled ceiling will keep most sound from affecting ductwork.
