Iam building a new home and have decided to go with advantech sheeting for the subfloor and 1/2″ advantech sheeting for the roof on 24″ center trusses. I could not find any 4’x9′ advantech sheeting for the exterior walls(I am assuming they dont make it?) any sugestions for the next best thing?
Thanks, Mike from Pa.
Framing the floor inside a crawlspace foundation keeps a gable-end addition close to grade.

1/2" sheeting
I am looking to hear the comments regaurding the 1/2" on 24" centers! Is Advantech that much stronger then reg. ply?
1/2" sheathing on 24" OC
1/2" sheathing on 24" OC roofs is the norm here. Pretty much everyone does it.
Same here
Yup. Same out here in the Great Northwest. Made the switch from CDX to 7/16"o.s.b. with H clips sometime around the late 80's.
When I have the chance I like to space rafters/trusses 19.2" to stiffen the o.s.b., but then skylight opportunities are reduced. Lots of things to consider.
24"o.c. with 7/16" o.s.b. is far and away the most common roof here.
not too many options...
This is 9' walls over slab floor right? Otherwise I'd want 10' sheathing which is supplied in osb.
I've never even seen 1/2" advantech for sale which does not mean it isn't a good idea.
As for the 1/2" ply over 24" o.c. roof it's done all the time, even with 7/16" osb with seemingly few ill effects.
None the less 5/8" seems prudent, especially with osb.
'Course all this is no help to your question about how much stronger advantech is, seems to me it's largest advantage is stability especially during construction which is less concern for walls or roof.
Blocking.
Piece it together using 8' and block the edges. The blocks can be put in flat and don't need to be nailed to the studs. Just hold the block behind one sheet and nail the ply edge to it being careful not to shoot your hand. Then nail the other sheet to the block. If you're hand nailing you'll need to nail the block in first, but you can still put it flat.
Here's a place where screws might be a better choice.
