   Jeremy,

   I've only installed plywood perpendicular (greater number of ply's) to the studs. In my opinion this is the "approved" method of installation. This is not to say that you are wrong, just you might have been able to do better.

   *What were you told was wrong about it? The fact you installed in vertical as oppesed to horizontal? True its stronger horizontal but nothing wrong with the way you did it. I frame FT and we always install it on the walls vertical just because its easier when you platform frame.

   *I have always thought it to be stronger to install sheating perpendicular to framing, staggering joints on courses. Recently read that this isn't necessarily true. If all edges of "upright" sheating are directly nailed to plates or blocking, these folks claimed it was as good. Think of T-111, that single wall approach if sure strong enough and that sheating is installed paralell to framing. It may be true that perpendicular is STRONGER, but at some point, added strength isn't needed. - jb

   *Jeremy:Yes, ply needs to be run horizontal. Oh well, its only a pool house for God's sake, right? No big deal.

   *Not only is strength not an issue when going sill to plate, but unless your building has no brace panels or alt. brace panels(which around here now would mean that it has no corners) you're going to have to install some vertically just to meet code. I just dont see how stepping into your newly sheathed building and seeing daylight coming though the middle of all your walls can be good news. I sheath everything vertically and block all walls over 8'. I dont count on felt or wrap to do anything but protect my sheathing. The only advantages I can see to sheathing horizontally is that it requires less nailing (6" o.c. every 8') and perhaps goes on a little easier, especially the second course.JonCP.S. This doest apply to roof sheathing, thats a whole different ball game in regard to strength axis.

   *Wow someone still uses plywood on walls. It's all OSB around here. Haven't paid attention to which way the S's were O'd -- i think vert. -- but will take a look. With roofs and plump contractors, altogether different Q....

   *I was always of the mind set that the sheathing should be run side to side across the studs. The joints should always be staggered by two studs. The logic here is that you will never have a joint in the wall sheathing that runs the length of one stud from sill plate to double plate. They tell me that this adds strength to the wall. However, I've seen it done both ways, and we don't have a rash of homes falling down around here because of one method vs another. Ed.
