I've read here that stud walls need only be 24" centers and not 16" centers. Is that true for external load bearing walls as well?
Green Glue question: My wall assembly will be as follows:
Brick vaneer
1/2"OSB
5/8" OSB
2x4 Stud wall w/fiberglass between studs
2" air space
2x4 stud wall w/fiberglass insulation
5/8"GB
Green Glue
1/2"GB
Questions:
Do I need double layers of OSB behind the brick?
Do I need Green Glue between the OSB layers?

If you keep one thread going in design phase its easier to see all your plans. :wink: without having to check all your threads. And once your in construction phase move on over to the construction thread and start a new one To answer your first question. Load bearing or external walls will be up to your local building codes and your vertical load. But typically 16"oc for 2x4 construction. G.G. between the OSB would be nice but given the logistics of your property I wouldn't see the need. And yes I would do two layers of OSB Peace TomI also plan to hire a local draftsman to create a set of plans to scale so I can accurately calculate and price materials and know what I'm getting into material cost wise.
You mentioned it your other thread when I asked about it there but something did not click on me at the time.
If the OSB is attached to the brick with plaster or something similar, you will have a triple leaf. If the OSB leaf is required by building code, keep it as one layer, and a layer of drywall to the inner leaf.

Hey Andre,
Might be misunderstanding what you mean by a third leaf so I did my crude drawing unlike Glenns :lol:
With two OSB sheets together and brick veneer with adhesive I am thinking this is one leaf. But please correct me if I am wrong
Peace
Tom
How thick will the adhesive be? The system becomes a double leaf if the brick and OSB are not firmly attached to each other.

Think of it like you were installing tile ....same concept anyway Found some pics on a DIY site Peace TomHow thick will the adhesive be? The system becomes a double leaf if the brick and OSB are not firmly attached to each other. Andre
That will work fine making the system one leaf. AndreThink of it like you were installing tile ....same concept anyway Found some pics on a DIY site Peace Tom
James is talking exterior brick veneer. In his case, the brick will have metal ties that will be attached to the OSB that is attached to the framing of this room. There is typically a 1 inch air space between brick and exterior wall to allow air flow.

Sorry, I will start a new thread in studio construction soon. I hope to start on the slab forms this weekend. I also bought a new camera to document my progress!If you keep one thread going in design phase its easier to see all your plans. :wink: without having to check all your threads.

Cool, SO I'll skip the GG between the OSB, (Man that stuff is expensive!). 2x4 studs 16"oc. I estimate I'll need 10-11 CASES of GG. I wonder if I'd be better off going with the bucket and troweling it on? Anybody tried that method?To answer your first question.

Although the answer is correct for 2x4 framing - if you used 2x6 framing at 24" centers you actually get better low frequency isolation - which is what I would opt for seeing as that is the problem frequency range you have to deal with (if that is good then mid and hogh frequency ranges are automatically excellent.). Rod2x4 studs 16"oc.
I guess I could spare the few extra inches the 2x2 framing would take up. I'm thinking the switch from 16" oc to 24"oc might offset the added cost of 2x6's as well.Although the answer is correct for 2x4 framing - if you used 2x6 framing at 24" centers you actually get better low frequency isolation - which is what I would opt for seeing as that is the problem frequency range you have to deal with (if that is good then mid and hogh frequency ranges are automatically excellent.).

Assuming this is due to code, make the OSB layer one panel, and add an extra layer of Drywall to the drywall leaf. AndreThat's exactly what I have.James is talking exterior brick veneer.

Sure, great idea - just make sure to use an exterior gypsum product. Dens-Glas would be the best choice - and it even hass slightly greater mass than standard gyp-board. Install your structural sheathing first - and then they gyp.
