My father is installing a pocket door, and he has to narrow the
doorway by 1 inch on the pocket side of the pocket door. He has 3/4"
oak strips he'd like to use. He was thinking of using 1/4" plywood or
1/4" MDF to make up the difference (it won't be visible as the trim
will cover it anyway). I'm wondering if either the MDF or plywood
will rot/warp/fall apart over time, and how it should be treated prior
to installation.

Thanks

Shims are standard method, adjustable, easier to set
the jambs dead plumb.

MDF or plywood would both be OK. I think I'd prefer plywood, but I'd
like to see MDF glued on if he used it, in case it did try to separate
near the edges with a nail or screw going through it. Both are solid
enough for final shimming to fit the new jamb and trim.
