Polycarbonate twinwall sheeting is the perfect glazing for any
greenhouse application and many other construction applications. This
material translates its many unique features into cost saving benefits
for you. This is one of the heaviest sheets of this type in the
industry and is manufactured in North America by the leaders in
polycarbonate extrusion research and technology.
The surface of this material is protected from the degradation effects
of UV radiation by a proprietary co-extrusion process. Beneficial
infra-red light passes through the material promoting an ideal growth
environment. In addition, the resins used to make this polycarbonate
are specially developed for excellent flame retardant properties.
Effective heat loss reductions from polycarbonate when used instead of
regular glass. Savings of up to 50% have been documented while using
this glazing. Insulation values increase with thicker sheets, see
standards table below.

Check for plastics distributors in the Yellow Pages. In the Des Moines
book they're listed under "Plastics - Rods, Tubes, Sheets, etc."
Ask for a price quote from every one of the firms listed - a given
item may be priced very differently from distributor to distributor
(two local distributors quoted a 4x8 sheet of polycarbonate mirror
material with a $00 difference in prices).
John, I pay between $5 and $0 for 6 mm twinwall polycarbonate
shipped from an east coast plant. You should be able to do better.
