Mixing Metal and Wood Framing
Posted: Tue Mar 09, 2021 2:19 pm
Hi Guys,
For context, here is my home studio design and use case:
https://www.johnlsayers.com/phpBB2/view ... =1&t=22719
I originally designed my room with wood studs on 16" centers but I learned from this site that I'm better off with 25ga metal studs on 24" centers.
I have a beam and pole in the room that I need to encase with drywall and I think wood will be much easier for that. There is also a duct that I need to enclose at the rear of the room (see image with arrows).
My homemade broadband absorbers weigh about 20 lbs. each and I plan to mount them to a 2 x 4 structure that splays and varies the air gaps behind (the first absorber is 1.5" off the wall, the next is 3" off the wall, and the last is 4.5" off the wall). I'm not entirely confident that metal studs will hold this weight, so I plan to put some wood blocking in key areas where I'm mounting acoustic treatment (see image).
Between the wood encasements and the selective blocking, it's still going to make sense to use metal studs, correct?
If nothing else it's cheaper right now, but I know that adding stiffness to the walls will reduce the STC.
Thanks in advance for any feedback.
Todd
