I had need for some mylar, so I bought a 100' roll. This will give me
enough left over to make some storm windows. I'm thinking of ripping
some 3/8" thick or so pine frames and gluing the mylar on the sheet by
setting the frame on the stretched mylar. One sheet on each side, it's
about 7 cents a square foot for 1 mil. Very transparent. These would be
inside the house storm windows. Mylar is very tough, but needs a UV barrier.

I don't know how to create the needed UV barrier.

What I wonder is what to do about possible moisture between the mylar
panes. Should I leave an air gap, seal it up, or add some dessiccant.

Ideas?

I recommend sealing all the wood before installing, wood is porous. A few
grains of rice in the bottom of the storm window might absorb the captured
moisture.
