Osb Siding Problems

This is not the case nearly as much with the plywood version of t1 11.

Osb siding problems.

Osb s lower quality means that it becomes very vulnerable to moisture. And cover them with 7 16 osb and then half inch dow blue foam board. With some understanding of the physical properties of osb we can determine the most likely cause. The problem was solved by removing the offending soil heap and replacing the rotten timber and osb.

The stigma around t1 11 today is its legacy of water damage. The most common failure is the appearance of a warp bow or buckle in the sheathing used for exterior walls. We frame with 2x6 studs 24 o c. Over time delamination edge checking and buckling are likely to happen as the glue slowly gives up.

The osb is nailed on correctly but is bowing out from the house between studs a good 4 5 inches. As with most construction failures there is no single smoking gun problem and no silver bullet solution. 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. Wood siding will expand and contract in changing weather conditions and when installed tightly no room is allowed for these patterns causing the buckling.

The type that really had issues was the lap type made by louisiana pacific lp.
