Hi,

This topic had come up before, but I keep getting conflicting advice
so I wanted to dedicate a thread to it.

When boxing in skylights, I being told that one does not want to use
drywall for the skylight window bay. The supposed reason: either the
hot air, or the humidity, or the intense sunlight will rot the drywall
over time and one ought to use plywood. In this newsgroup, I believe,
I only heard the opinion that this is either total nonsense or, at
best, obsolete old school idea.

So, if you do agree with plywood over drywall, please post your
opinion and your reasoning.

Many thanks in advance,

Aaron
