The osb is nailed on correctly but is bowing out from the house between studs a good 4 5 inches.
Osb siding problems.
Osb s lower quality means that it becomes very vulnerable to moisture.
The problem was solved by removing the offending soil heap and replacing the rotten timber and osb.
The type that really had issues was the lap type made by louisiana pacific lp.
The 7 16 osb sheathing on the sides of the house is buckling so badly it had caused the vinyl siding to unzip itself.
We frame with 2x6 studs 24 o c.
Wood siding will expand and contract in changing weather conditions and when installed tightly no room is allowed for these patterns causing the buckling.
See how osb has decayed from prolonged contact with ground to same point as regular timber my point here is that osb will rot when exposed to high levels of moisture but just the same as any other timber or plywood.
Over time delamination edge checking and buckling are likely to happen as the glue slowly gives up.
With some understanding of the physical properties of osb we can determine the most likely cause.
Why osb grade t 1 11 siding fails the problem with t1 11 siding however is not with its cost functionality or even the aesthetics.
The stigma around t1 11 today is its legacy of water damage.
This is not the case nearly as much with the plywood version of t1 11.
And cover them with 7 16 osb and then half inch dow blue foam board.
