Re: Anyone Have Experience With MDO Sheathing?
I just did a project for a client using MDO...it's very nice from a surface standpoint. Do note that there are two grades...one is a little more expensive, but there's no telegraphing of the underlying wood layer through the paper cap. MDO is rated for exterior use, but you MUST fully seal all the edges. It's still plywood and despite it being mashed together with exterior rated adhesives, direct moisture exposure on the edges will cause damage over time. No surprise there. Banding with PVC will help with this and certainly make for a much nicer edge, but sealing the wood edges first before it's application will increase life for sure. As to screw holding...it's plywood. If you use the correct type of screws, it will perform the same as any other plywood appropriate for the application.
And yea...MDO is going to be light years more stable than PVC or similar. The latter can have substantial expansion/contraction in all directions based on temperature.
