Briefly, I’ve got 1/2″ OSB for exterior wall sheathing. Should I install it vertically or horizontally? Does it make a difference?
Any advice, pros, cons?
thanks,

These plywood clips allow you to strengthen the walls around pocket doors to support shelves, cabinets, and other fixtures.

I run mine vertically, if you run it horizontally you usually have to run more blocking in order to nail off the edges of your sheets. Dave
*Look here. Hanging SheathingJames
*Isn't this Oriented Strand Board?It shoudl orient itself automatically.
*OK, i've read the other thread. Summary seems to be to run the sheathing vertically, because to get the maximum shear strength the panels must be nailed on all edges.Now, my understanding is that the exterior sheathing is supposed to extend down over the rim joist, and down about 1/2" past the mudsill.If I do this, the top of the vertical sheet isn't going to reach the top plate - so, must I block the top of the sheets to get the best racking resistance?thanks,-TJ
*hmmmm... it's never easy , is it ?you need a shear panel from the bottom plate to the lower of the double top plate...you also need tie downs to the foundation...and , if you have a 2d floor.. you have to tie the 2d floor to the 1st floor... usually you use a full panel for the wall.... erect the wall.. then strip in the band at the bottom...if you have tie down requirements due to high wind or seismic design.. you use an engineered clip or tie-down to tie the levels together..if you can do your plywood layout to span from sill to stud.... then from 1st fl. stud to 2d floor stud.. some of these clips can be eliminated...depends on wether or not you need the full shear value or the tie down value...if you need both.... then you have to use the shear panel and the clips.. ( for example .. a Simpson tie-down like an H1.5 ) ....hope that's clearer than mud.....
*Here's what you do... Take a coin, I prefer quarters since they're a little easier to flip....
*TJ:You say:"Now, my understanding is that the exterior sheathing is supposed to extend down over the rim joist, and down about 1/2" past the mudsill."That's not the way I do it. If the OSB comes in contact with the masonry foundation, it will wick the moisture out of the brick/block/concrete and rot. I hold mine up from the bottom of the mudsill about 1/16 to an 1/8th". Further I set my mudsills in 1/2" from the outside of the foundation so that the sheathing will come out flush with the outside of the masonry/concrete foundation, which would pretty much preclude running the sheathing "down about 1/2" past the mudsill".
*The only kind of job I know of where you have to run all shear / sheathing horizontally is on a Calif. school. Because the min. lap is 24" and the row above works out better running it flat. By the way, NO OSB! Strut 1 ply only. Mostly union jobs.
*You know this Horizontal vs Vertical has been hashed, rehashed, regurgitated and generally pummeled to death. OSB and Plywood sheathing are manufactured so that it really doesn't make any difference which way they go as long as the nailing schedule and span requirements are met. BUT some local codes and some regional customs say to install a particular way.So, follow the local custom and code or someone will think you are weird. Most of the time that is ok. But here it might interfere with your wallet so it might be a good thing to avoid.
*Run the sheets horizontal with a full sheet starting the first row and a half sheet starting the next. This makes the wall more flat by connecting more of the studs together. Lap the foudation 1/2 inch. I cover the bottom edge with coil stock left over from siding jobs and caulk it to the concrete to keep out insects.
