I don't think it could work....it would be like turning your feet sideways and hoping they keep you up if you lean forward. Drywall puts constant pressure on studs (like holding a toddler...pressure is down and forward)
The difference between doing what your suggesting and doing it properly with a 2x6 is only 2". Is there anything so critical in your plan that loosing 2" (or 4" if two walls) is going to make or brake your space?
Double drywall and green glue adds mass and damping. Staggered studs adds an element of decoupling as well.
You're right. stop messing around "me".
2x6 decoupled it is. I understand that 24" OC is better somehow. is the 24" measurement taken from stud to stud on both sides of the 2x6, or from one side of the 2x6 (measuring on one side of the wall)
does my question make sense? sorry, i see all the diagrams but none have measurements. I picked up the green glue and am looking for soundproofing insulation. thank you all.
does spraying poly insulation on the inside of one wall help to seal leaks and add mass - I notice no one talks about this type of insulation at all.
the ends of the wall are no different than the top and bottom plates. Those are areas where there may be some coupling but the largest expanse of the wall is isolated. If you wanted to over engineer this You could put one 2x4 on one side at the end in the regular position and another 2x4 on the oppostite side starting at 2 inches from the end leaving a 1/2 inch gap You can cantilever that edge of the drywall that 2 inches. Particularly if it is a double 5/8 wall. On clip and channel systems often a channel is 6-8 inches from the corner and the drywall is just left hanging.
excellent! problem is that the drywall would cantilever to the cement wall in the basement.
is the 16 (or24") OC measured from the first stud to the next staggered stud, or the next stud on the same side of the baseplate?
the cement wall is the exterior wall (insulated cinder block basically) . i was planning on rotating the pressure treated studs 90 degrees so that the wall is sealed but the studs dont bridge to two pieces of sheetrock (or four, technically).
LIke in the diagram above. S'ok?
ya, its unusual. the concrete wall is a cmu architectural block wall. 2 cell block with foam in one cell and rebar/mortar in the other cell. it gets a mastic coat, then a polymer coat, then a paint coat and its finished. no need to frame that wall. our entire basement and first floor has this.
its a napkin sketch. i dont know how to do the fancy computerized sketches I see here.
i finished the rough framing last night. its really intimidating to look at all your projects. I hate to cut corners but I have some financial limitations, so in order to compromise a little bit- im doing some of the work on my own.
