Galvanized Tin Wainescoting on Studs, Backer needed?

[Beal095]

See the attached picture. I am putting galvanized tin wainescoting in with J trim on top and bottom. Right now the walls are bare studs with bat insulation. WIll the J-trim be enough to support the edges that fall between 16" centers (sheets are 24" wide). If not, I've considered cutting 3" plywood strips and running them on top, bottom and middle to help support the tin.

Have you done this? Any recommendations?

Instead of ripping down a sheet of ply, I'd just run 1x3 or 1x4's.


Vapor barrier on the studs & then the 1x's maybe?

run 1" x strips parallel to your studs (purloins), then attach the tin to those. You will have to shim out whatever you are putting above the tin or just run purloins all the way to the ceiling.

The ribs in the tin need to run perpendicular to the framing. If you want the ribs to be vertical then you need horizontal strapping behind the tin.

I definitely want the ribs to be vertical. It’s extra work, but I may just nail 2x’s horizontal and flush between the studs so the tin isn’t spaced out from the wall. Sheet rock will be above it. I can use quarter round at the base of the sheet rock/top of the tin if I space it out with plywood. But flush 2x’s would be cleaner.

Spacing the tin out further than the rock really isn't an issue. I don't think I've ever actually seen it done flush. Most that I have seen used a 1x to cap the top of the tin. I'm guessing a lot of it has been put up over the top of existing sheetrock.

Looking at the same install but with 1x furring strips on the surface of the studs. If you place your 2x4 horizontal nailers flush then you will be reducing your insulation loft and thus reducing r-value. Just my $.02

More money but consider laying ply behind it. Or drywall do give it a solid backing. Not needed but better

I think burleyfarm's and Kaizen's suggestions are good. The advantage to horizontal nailers + furring strips is keeping as much advantage that insulation might provide for echo/noise reduction. The advantage to putting plywood behind the tin is the ability to 'surface mount' shallow new work or outdoor boxes wherever you want for electric.

Dont forget vapor control.

A standard taped and painted sheetrock wall *IS* vapor and air control.

Corrugated tin w lapped joints isnt.
