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.

Double glazing relies on sealing the air between the two panes. If
you decide to go ahead, try to seal your polycarbonate panes with
sticky tape round the edges. In fact, if you use a good quality tape,
you probably don't even need to do any screwing at all.
