I read an article once where a home owner put 1/2″ ply wood on all walls and added 1/2″ drywall on top. Reason being for extra insulation and as a sound barrier.
I’m ready to do this but stopped short when i was considering adding jean material for insulation and it calls for plastic as vapor barrier?
Any thoughts if this is a good idea to add 1/2″ ply?
thanks in advance,
Mark

My cousin did it in every room, and it made for a very quiet house. Little boy couldn't kick holes in the drywall, either ! And that kid could tear up an anvil with a banana.
This house was moved about 6 miles, then stripped down to the bare studs. At times, over the one-year renovation, I really couldn't be sure what could possibly be holding the roof structure up - so in this case, the ply helped in more ways than one.

Sounds like a good tip for rental properties and tenants with bad tempers.
if thats the kind of tenants you plan on having,save yourself some grief and buy gm stock.the older i get ,
the more people tick me off
I always figured if I ever built rental property I'd use 3/8" OSB topped by 3/8" drywall, for the durability. That only adds 1/4" to overall thickness, creating less of a problem for outlets and the like.
Though now that I think about it the fiberglass-reenforced rock we were using in Eastern KY a few years back might be the way to go, in terms of resistance to damage.

I've had a couple homeowners have me put up 1/2" plywood under both drywall and 3/4" wood paneling. I liked it enough to use 7/16" osb under 3/4" wood paneling in an addition I built for myself, thinking it would help here in tornado country with slowing down debris missiles and probably shear strength. Of course you have to deal with the extra thickness on door and window jambs. If I were building anything for myself again I'd do it again, budget allowing.
Don't know where you are, but check with your permit dept. about the vapor barrier. I use the denim stuff here (OR) and they don't require a VB.

Fill out yer profile! Building info is site specific.
I did 7/16 OSB on the inside when I redid my bedroom, denim in the studs too, as I go through the other rooms I'll continue. I don't know about sound, as my kids are upstairs and sound mainly travels through the windows for me.

Look, just send me to my drawer. This whole talking-to-you thing is like double punishment.
I've done this to cure some recurring plaster cracking problems, e.g, where a stud wall meets up with a masonry wall. Bridging the whole wall with ply eliminated the problem. It sure makes trimming out and hanging stuff on the wall easier! No matter where you put a nail, you hit wood. ;-)
FWIW, you can still put your plastic behind it.

Everything fits, until you put glue on it.
when I built my house I did the same between the house and the garage. I knew it would be a while before I could afford garage doors so I wasnt going to make access as easy as kicking out the sheetrock
Want sound transmission reduction use quite board one sheet 1/2 is equal to 8 pcs of sheet rock. want additional use Sound attentuation barrier in Batts 14 1/2 wide by 4 feet in 3 1/2 " thickness
1/2 plywood is hardly the way to go
Quietrock is ten times the cost of a sheet of plywood here.
Yeah for the price of that stuff we could just fill the walls with concrete.
in New york its about 8 times , yes you are correct , then deduct the cost of handling the plywood , screws and labor to install it , its about 4 times
Homasote would probably provide better sound attenuation than plywood or chip board.
If you want added insulation and sound barrier add 1/2" EPS or Thermax not plywood.
I've used OSB on inside face of studs to stiffen old structure, and to replace depth to finish trims where plaster and lathe had been stripped. It also has the advantage of giving a solid nailer for hanging art.
