Bob,
Is greehouse glass a special kind? Actually, a lot of the greehouses I
see around here are made from flexible plastic sheeting over aluminum
tube framing. Bubble type house add-ons (I photographed many of these
when doing photo illustration for magazines like Practical Homeowner)
are often made of plexiglass or similar rigid clear plastic. How do
these plastics affect UV transmission?---Carl
