I've been using mylar for various things, adding extra layers of
glazing cheaply. It's dead clear. It does deteriorate under UV and needs
to be protected from UV.
So far I've been using Sun Tuf, which has a UV shield on the top,
polycarbonate needs to be protected also. What I don't know is what
other plastics/glazing blocks UV. Acrylic and PVC as well as
polyethelene are widely available. I'm fairly sure that the poly is
transparent to a wide spectrum. I think vinyls and probably most
plastics pass UV, but I really don't know and I can't find good data on
Probably have to look at individual polymers. Ability to pass UV is not
necessarily related to stability as polymers such as polyethylene and
polypropylene degrade readily without stabilizers.
I think those with aromatic rings like polystyrene and polycarbonate
absorb most readily.
For glazing and lenses, polycarbonate and acrylic are mainly used.
