re: OT carpenters, additional decking in my attic- NSFW

Go with 1/2" osb. If you cut it 24"x8' like someone said, run it across the studs. If you put a joint at every stud, you'll get sagging.

You certainly don't need 3/4" for an attic.

This. Anything more than this is doing too much.

I asked a guy doing some renovation work at my place and he said he'd use 3/4 plywood. I have a small door in the back of a closet, maybe 2x3, and he suggested doing the 2x8 cuts as was mentioned here. Then lay them staggered across the beams. I was going to deck an 8x10 area so he suggested this so there wouldn't be a seam and the last two feet be all shorter pieces.

My reason for doing it is to increase closet space and out of season storage boxes. I'd be tearing down the drywall in the back and making a full height opening instead of the half door.

Easiest thing to do is buy some 1x12 8' ponderosa pine. Easy to carry up and will lay down fast. Very cheap.

Stagger your joints and use metal joiner clips between your joists. It makes a ton of difference.

Sounds like we got a lot of handy guys all up in this thread.

Thank god the OT didn't build my house.

I think we are talking about the attic floor, not a wall.

Double up 1/2" osb. It's cheap and by running it 2 ways it will be as strong as you could ever need it.

1/2" is plenty thick for attic decking and it's also going to be all around easier to handle. Use screws and some pieces of "dead wood" where needed if you're worried about it.
