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.

Double width studs for isolation?

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! |
