Over time delamination edge checking and buckling are likely to happen as the glue slowly gives up.
Osb siding problems.
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.
Wood chip siding has been around for many years but in the late 80 s and early 90 s a certain type of osb oriented strand board siding really became popular around salem oregon and the pacific northwest.
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.
Osb s lower quality means that it becomes very vulnerable to moisture.
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.
The osb is nailed on correctly but is bowing out from the house between studs a good 4 5 inches.
With some understanding of the physical properties of osb we can determine the most likely cause.
The most common failure is the appearance of a warp bow or buckle in the sheathing used for exterior walls.
As with most construction failures there is no single smoking gun problem and no silver bullet solution.
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 7 16 osb sheathing on the sides of the house is buckling so badly it had caused the vinyl siding to unzip itself.
