Building Walls

[d.reinhart]

I have a question for you all.

I am thinking of putting girts on my walls on the inside of my shop. Then hanging 7/16 OSB and then putting drywall over it to make it look nice. The thinking of this that I can hang anything I want up and not have to worry about hitting a stud. because of the OSB.

As for the girts I wanted to use 1/2" plywood.

So what do you all think of this madness?

If your pole spacing is 8ft like normal I think your panels will flex a lot without much support on the backside, and that might cause issues with the drywall, especially if it's finished.
Some bookshelf girts between your posts would probably be enough to prevent too much flex, and wouldn't cost a whole lot, especially considering what OSB costs these days.

IMHO, 8' is very long for unsupported plywood. If double them up and stagger stagger the joints you will see a tremendous increase in rigidity.

Sorry I see I forgot to put in here. I walls have 16" centers so I am not 8' apart on them.

I think it would be pretty sound, but why not just get AC plywood then paint it? It's only a little more expensive than OSB or CDX, both of which are outrageous right now and would take paint well while being quicker, cheaper and more durable than drywall if not quite as nice.

A lot of AC plywood is "interior only" (glue is not moisture resistant). BCX would be better.

You don't need girts, plywood AND drywall especially on a 16" O.C. stud wall ! Maybe place 2x4 spacers/blocking between the studs at 2 levels.

Drywall damages easily. Stick with 1/2 plywood. Use a good "stain blocking" primer and a couple of coats of satin/gloss exterior paint.

16" on center, just put up sheet rock. You know where the studs are, & sheet rock holds anchors well, or use toggle bolts! Either are good for holding things to a wall & repairing holes when you remove things is quick & simple.........

I'm not sure what the girts are for, unless it's to create a thermal break. I agree with Jinks, just putting up sheetrock makes the most sense if you want a finished look.

The girts are being used because it is a older building. None of the walls are square or even at 16". Each one is either over or under. So I wanted to get away of having to cut each one to make it fit.

Your plan sounds like it will work. The OSB will also help stiffen the sheet rock which will help resist damage when it's accidently bumped. I've used your plywood girt (strip) method in a similar situation and it worked well.

Osb ***** to try and attach things to. Dosnt hold a screw well at all.
