Elevick...When working on a 200plus year old house (like mine) studs are where you find them. Often they are rock hard hemlock that you can hardly get a straight nail into. Makes life interesting.
Double width studs for isolation?
Before I drywall my new dedicated room I was wondering if it would be at all beneficial if I added an extra stud to each/some of my 24" on center studs to increase the amount of surface area the drywall was screwing into and thereby conceivably decreasing the "intensity" of energy transfer through them into the outside walls? My goal is to reduce noise transmission through the walls. I will be using 2 layers of 5/8" drywall with Green Glue between. It's not a lot of extra work and I already have some extra studs. Just a thought. Thanks. Grant

Lots of advice, thank you all. I'll probably stick to my original plan although that quietrock does look very intriguing.. -I might add a layer or 2 of the heavy gauge tar paper to the inside edge of the studs to add a little cushioning/isolation before I screw the double drywall to them. I've been caulking all the seams between ceiling and walls, then I'll do floor to walls too. I'm hoping the Green Glue is very effective between the drywall. Thanks again. |
Lissnr, Did you check out the QuietRock 525? One layer of the 5/8" thick 525 is equal to 8 layers of standard 5/8" sheetrock. |
Jea48, I just checked out the QuietRock 510, which is $$$ less than the 525 (it's 1/2") and looks very good too. It's said to be 4-6 times better than double drywall and only a couple of STC's less than the 525. 1/2" won't be to "fire code" though, as compared to 5/8" which is. It's in a detached garage... should that be an issue??? (No bathroom, bedroom, or anything... just a "Hang-out" room).Thanks, Grant |
Elevick, You completely misunderstood my post. by 'stagger' I mean that there are 2 sets of studs, not studs at random intervals. Both sides of a dividing wall are NOT attached back to back on the same set of studs. This will couple them 100%. Instead: try building 2 half-walls back to back. Total thickness should be maybe 6" using 2x4 studs. 1 set is covered by sheetrock facing room 'A'. A second set of studs *between* the first set and offset about 2" are used for the 2nd wall, being room 'B'. Weave a dense sound insulation/damper BETWEEN the 2 sets of offset studs. The 2 walls are now decoupled..bass and have insulation between them...for HF. BOTH walls will be 16"oncenter, but offset 8"...... Man, I wish I could attach a simple drawing! |
