OSB interior wall thickness

[Keith S]

I'm about to put up OSB on the interior walls of my pole barn and was wondering what thickness to use. Is 7/16" acceptable or is it worth the extra money to get 5/8" or 3/4"? I will need roughly 50 sheets so the cost difference may come into play. I would like to be able to mount shelves on the wall and not worry about hitting studs.

Thank you
Keith

I used 7/16 and have no regrets. Unless you intend to hang something particularly heavy I would go with the 7/16th stock and use the money saved for something else like lighting, etc.

I used 7/16 as well. It's not structural or anything so 7/16 is good to go. What is the price of it now? I bought mine 2 years ago for 8.50/sheet.

I'm in the process of putting 7/16 up as well. Remember you can get 4x9 sheets as well. Depending on how windows/door/corners fall this size can work.

Thank you all for confirming my suspicion. The prices I am seeing are roughly $8 at Lowes and Home Depot and $10 at several lumber stores. Don't know about the quality difference between the two. This is for 7/16" non tongue and groove.

You're good to go, keith. Remember to put the smooth side out for a better finish.

I used OSB in a small pump house years ago and still hate it. I suppose it's alright for such things as barns, tool sheds, etc., but I've never liked the way it works and the stuff I had access to was way too porous for a good looking paint job. Also, it took a while for the glue/formaldehyde smell to go away. Some people have negative health reactions to long term exposure and when this happens, cost is at the bottom of the list of considerations.

Used osb. 3/4" t&g on the outer walls, and 7/16" on the office walls. The outer walls are secured to c purlin... That is the reason for the tongue & groove.

I used 7/16" on my walls.

If you're hanging some shelves that will hold some serious weight, you should try to hit the studs no matter the thickness of OSB you use. Just mark the floor or ceiling for the location of the studs prior hanging the osb.

You guys are making me feel like I got a good deal on the OSB I just bought. Paid 7.49 a sheet at Menards. I picked some up a week ago when it was 6.51 too. That was for 4x8, 7/16.

Nice. When I built it was 5.79/sheet. Then it went to $14. I used 7/16 on the walls and ceiling. Only managed to hurt it with the golf cart.

Buddy of mine just did OSB, I'll see what he used.

Starting to think about the inside finishing aspects of my project, I look at my attached garage and see the bruises on the drywall (skip coat not smooth). I would love to have a rustic feel on the inside of the new garage, how have any of you achieved this? (of course without spending a small fortune...)

Try looking in the country for an old galvanized/rusty corrugated building that needs tore down. Use the metal on the inside.



PM ratdoggy, I think he works in a scrap yard/recycler in your neck of the state. Maybe stuff like that comes in and cam let you know about it.

OSB was $7.05 for a 7/16" sheet at Lowe's a couple of weeks ago.

I am using it to finish out the walls in my shop. I have had good luck by painting it with two coats of original oil based Kilz followed by two coats of latex interior enamel. Your first coat of Kilz will almost disappear as it is sucked into the OSB. The second coat will give you good coverage.

Covered my shop walls in 7/16" OSB attached to steel studs. Area of high load, behind benches , grooved 3/4" plywood and installed inside the studs. With the OSB cover, a screw can be used any where to secure whatever. Not sure I would pay for this but I had a bunch of 3/4" plywood scraps. Screws were used so if there is a future need to access the interior sheets can be removed as needed. Used a laser level line to start the sheets so all of the joints are very tight.

Went to a local painting contractor and purchased 15 gallons of leftover paint, $5per gallon. Mixed it altogether and it ended up being a soft green which I like after painting and have been pleased with the results.
