Apartment Ceiling
« on: February 21, 2013, 01:19:38 PM »
I own rental property and I am in the process of renovating the first floor unit.  I have noticed I can hear the second floor (both foot fall and voices) in the first floor unit (I think this isn't as noticeable when you have furniture/etc in the unit).  I would like to reduce how much you can hear (or eliminate it if possible).

I have read a few forums and I plan to:
-Plug any holes in the ceilings
-Add insulated covers to all outlets/switches

My main question is the ceilings.  Two of them are currently damaged (water damage to the old plaster).  I was thinking that the resilient channel may be the most cost effective way for me to deaden noise.  Do I need to remove the old ceiling to install that?  Or is it more effective to put it right over the existing one?  I did look at noise isolating hangers/channel but that seems rather expensive at $4-$5 per hanger plus channel costs.

Also if I do need to remove the ceiling, should I insulate between the joists?  Or is that not very cost effective to cut down on noise?  And is there any sort of deadening fabric I should install prior to the resilient channel?

I'm looking to keep the cost down if possible.  The joists in the ceiling are 6" and spaced roughly 18" on center.  The house is an older home (probably late 1800s-early 1900s).  Steam heat, so no heat ducts carrying noise.

Second floor unit does have hardwoods and I would prefer to not carpet it.  But that may be an option depending on how well I can cut down the noise with other methods.

I'm open to suggestions if there are other ways to sound proof that I have overlooked.

You should absolutely remove the existing plaster and insulate the cavities. I would recommend using mass loaded vinyl stapled directly to the bottom of the joist then attach your resilient channel followed by sheet rock.
There are specific instructions for doing the install with out shorting the system.
I would recommend you call me direct to discuss the particulars of these type of installs to insure you do not make costly mistakes.

I sometimes recommend getting some mass up into the space between those joists to beef up the floor......cut up some 5/8" type X drywall and fasten it up there. Stumbled across an great illustration of that the other day.
