Polycarbonate Sheets - Multiwall,
Twinwall, Corrugated
Lexan, Polygal brands plus our Made in America line
Polycarbonate sheets have been our
top choice for greenhouse glazing for quite some time. Compared to other
greenhouse glazing materials you will get a much better insulation and the
polycarbonate sheets will last much longer than most other materials.
We carry 3
different brands of greenhouse polycarbonate sheets - Polygal, Lexan and our
Made in America line. To simplify things we have a side by side comparison of each
brand in the different thicknesses. At the bottom of the page we have also
compiled a list of all of our PDF's related to polycarbonate. We have a $500.00
worth of sheets minimum. This does not include U's, H's, screws, crating or
shipping. If your order has less than $750.00 worth of sheets there is a $25.00
small order charge. Please fill in a quote form or email us for a quote. We
cannot figure a quote for you over the phone. In order to quote we need the
number of sheets, U's, H's screws - the sizes and your ship to zip code. We will
not calculate a bill of material for you. The person designing the greenhouse is
best suited for this.
A common question is what is the
difference between the different manufacturers. They will have slightly different
qualities (light transmission, R value, U value, Shading coefficient, solar
heat gain coefficient and solar reflection). Basically, it has been our
experience that for greenhouse glazing purposes they will perform comparably
with the exception of the Lexan thermoclear plus which has a higher warranty and
should out perform the others. The Lexan Thermoclear Plus warranty states that
the light transmission will not vary more than 2% in ten years. All of our other
sheets carry a warranty that they will not vary more than 6% in light
transmission.
All of our sheets have UV protection
one side. This is to protect the sheets from breaking down from the sun. All of
our 8mm clear and some of our specialty sheets have the anti - condensate coating. This is a coating which will
cause any condensation to sheet off, rather than forming droplets on the inside
of the greenhouse. All of our sheets have a 10 year warranty against light
transmission variance and hail damage with the exception of the Lexan greca corrugated
sheets. They only carry a 5 year warranty on hail damage. Pricing is per square
foot plus crating plus shipping
