Wall sheathing, choice of material?

[Paladin]

I'm talking the inside of the exterior walls, around the windows etc.
I am thinking of loading up on some supplies and was thinking 3/8" plywood? What do you guys use, any suggestions and tips for doing these walls?

I used 1/4" luon to complete what the po had started.   I plan to anchor things to the bus frame underneath.

I used 3/8" plywood. Easy to work with. Thick enough that's it's stable and can provide some support to other walls, cabinets, etc.

[Paladin]

That was my thinking as well.

I used the 15/32 (1/2") sanded plywood..

It is attached over over 1X4's, spaced at 1'  and that run horizontal on the wall with insulation between.

I ran the 1X's closer near the ceiling where I may attach cabinets, giving me an actual 3/4 attachment point.

So far I am pleased with no regrets.

The 15/32 will give you a nice solid surface to attach to.

Dave, I used 1/2 " sanded plywood which doesn't cost much more than 3/8" and is stronger if you want to hang something on the wall. It was nice to attach cabinets to in the kitchen. It makes a nice rigid wall. Marc

Marcus,

Ya made me think about it.

Went out and measured.

I used the sanded 1/2 also.

I wanted a smooth surface to attach my unknown covering too!

I used 3/8" plywood on the inside of the sidewalls.

Hi Dave,

I used 1/4" in my bath interior wall and I wished I used 3/8".

Where I used 3/8" on the window walls, every seam has held up very well but, the 1/4" seams are showing signs of movement.

Good Luck

Guess I'm the odd one, I used all 3/4inch plywood for the walls and dressed them with 1/4 prefinished paneling in a white print. The plywood is screwed to the metal framework with 1/8th inch felt between the metal and the plywood to eliminate squeaks on the road if it ever moved.  Each hole for the screws was predrilled and metal framework was tapped for the screw and the screw was locked in place with epoxy so it wouldn't back out over time, my wife thinks it's over kill but I told her everyone does it that way lol. I'm not going to mention foam filling the hollow metal bracing for insulation and sound transference tho lol.

While were talking about walls!

Nick turned me on to the idea of using body filler on the joints, worked perfect.

   Half inch 5'x5' baltic birch plywood for me. Very high quality strong stuff and cheep. I was getting it for $20 a sheet 4 years ago. Don't know what it is now. Jim

I used 1/2" BC plywood.  I also put 15lb felt behind it as to minimize any humid air in the coach from condensing on cold bus framing and avoid any squeaking while traveling.  7 years now and has worked very well.

I was thinking of filler for the joints but kind of thought it might crack over time.
