Polypropylene Sheets

twinwall polycarbonate vs twinwall polypropylene

This picture shows our logo through clear twinwall polycarbonate on the left and twinwall polypropylene on the right.

This 8mm twinwall product is recommended  for greenhouse gable ends, bench covers and greenhouse sidewalls. It is not recommended to be used for roof applications with metal purlins. If you use it in this application you must insulate between the metal and the polypropylene. It is not clear like twinwall polycarbonate. It is a milky white. It has 87% light transmission. The polypropylene has UV protection on one side and it has a ten year warranty. The cost is $0.95 per square foot. Minimum order without shipping and crating is $750.00. It is shipped via common carrier the same as polycarbonate. The crating charges will also apply. The crating is calculated by multiplying the length of the longest sheet by $10.00 for 4 foot wide and $13.00 for 6 foot wide. Minimum crating charge is $80.00. Please contact us for a shipping quote. Please note: Shipping for polypropylene is done by Common Carrier (trucking companies).  We do not offer pick up. Also, we will not cut sheets small enough to ship UPS. If you are looking for less than 8 sheets we would suggest Solexx as an appropriate substitute. It can be shipped UPS.
