Replacement skylight installation
 
Hi guys,

I'm getting ready to have an installer replace old skylight with new VELUX one. Getting new skylight with laminated glass. Roofing installer and manufacturer both say my roof type doesn't need a flashing kit: old skylight's removed and new one simply installed on top of the existing curb, my understanding.

So, wondering from the soundproofing stand point, is there anything I can ask the installer for or provide with to make sure that the new skylight & installation is as soundproof as possible? Is there any caulking to be done, does he need to use green caulk, etc?

I'd appreciate any advice. Thanks!

No additional provisions to be taken.

Standard sealant between the curb and the new unit will do a good enough job of blocking and air leakage and sound transmission.

You will still get some noise via the curb and the wood will transmit the vibrations quite easily.

The laminated glass will help with the noise through the glass though.

Great! That's what I kind of thought too but what do I know. :) Thanks for confirming it for me. I appreciate it.

Yeah, that makes sense. I assume you're mostly talking about low frequency noise. Do you think having him apply strips of some kind of sound dampening material on the curb would help at all? Not sure how that could be applied though. Curb is taller than the skylight by quite a bit so it'd have to be on the inside. That would make it look odd/seen unless painted over to match. I'm just speculating here btw.

I would just go with the laminated skylight for now and see what benefit that nets you.

Yeah, may have to take it one step at a time.

I see you're local. Will definitely keep that in mind. :)

Thank you for your help.
