I have plastic lattice (4x8) sheets attached to the underside of my
deck. Each sheet is attached to 1"x2" stirps of wood that go around
the lattice. This provides a frame for the lattice in order to
secure
it to the deck. My problem is that each springtime, I've noticed
that
the lattice has cracked near the wooden frame in a couple of areas.
I
think this is due to the expansiona and contraction of the lattice
is
different than the wood framing.

Any ideas on how to resolve this issue?

We've never had that problem. Could be the difference in weather or
maybe because ours is installed with exterior wood screws through
holes that are larger than the screw giving the material room to move.
We use washers to keep the screws in place and the screws are not
tightened all that tight. Just enough to keep the lattice in place. We
only use 5 screws across an 8 foot section.
