Just an idea to run past the experts but would it be at all possible to
screw sheets of that polycarbonate stuff on the inside of glass for
winter protection? If I drilled holes in the sheets and screwed them to
the wood structure would it be better than bubble wrap which is a swine
to re use and clean.
