Skylight and Recessed light
« on: April 29, 2012, 05:57:29 PM »

Hello everyone,

Thanks to Randy and many others, I feel like I am a bit more educated now about soundproofing residential homes.  Randy was kind enough to warn me about recessed lights so I am avoiding them as much as I can on the 2nd floor as I fee like noise will go right through and be amplified by the cans.  I presume skylights are probably no different and perhaps worse given their size?  I've been trying to located STC info on a few Velux brand skylights but to no avail.  One agent just said about 30 STC which I presume will be far worse than ceilings without skylight.  I think I know the answer but just wanted here from you guys - skylights do negatively impact soundproofing?  I could use more light in certain rooms but not enough to introduce unwanted noise (for me it's the airplanes).


Thanks!

You would have to do a double panel system...the original sky light followed by a second panel of plexi-glass installed 6+ inches below the sky light...you need to accomplish the dead air space...and yes windows/ skylights would negate some of the sound control.

As always thank you Randy!  Would this cause any issues with condensation? Is it as simple as putting plexi glass in the tunnel as you described?

Sorry for yet another question but are ceiling mounted lights that much better in terms of soundproofing performance than recessed lights?  I presume you still need to go through the ceiling and have a smaller box for the fixture.  I am also planning to get those putties to put over the electrical box from the ceiling.  Thanks

your correct, we recommend a box covering for any recessed lights .and for pancake boxes the use of putty pads on the back is the way we deal with outlets.
