Polycarbonate has many desirable features making it a popular choice for greenhouse
glazing. It carries ten year warranties against light transmission variance and hail damage.
It is 1/6 the weight of glass and 1/3 the weight of acrylic making it easily to handle. It has superior insulation qualities. The UV coating contributes to the excellent weather resistant quality of polycarbonate, protecting it from yellowing and degradation. It is virtually unbreakable with an impact strength 200 times greater than glass and 8 times greater than acrylic. Polycarbonate is also flexible and easy to install. We are now proud to offer a choice between Lexan polycarbonate products, Polygal polycarbonate products and our Made in America polycarbonate. These are three different manufacturers offering different options with excellent products and reputations. Please see the product pages for specifications on the particular product. Please note, all manufacturers offer different products. If it is not on the specific manufacturer's page, it is not offered from this warehouse. We will not mix orders from two manufacturers to meet the minimum order.
Please do not call for a quote for polycarbonate. We will not accept quote requests by phone. There are two reasons for this. 1) We must wait for a shipping quote from our freight carrier and are unable to do this immediately. 2) These are custom cut sheets and there is a risk of a transcription error when the bill of material is taken over the phone. Please do not ask us to figure a bill of material for you. The person designing the project or the person installing the polycarbonate should figure this. It is impossible for us to know exactly how a project is designed to go together.
To see which polycarbonate is right for you, please read the specifications from the manufacturers and compare it with what you are trying to accomplish in your greenhouse regarding light transmission, insulation factor, etc. You should take into consideration what plants you are growing and their requirements. Also, if you are in a harsh or moderate climate and if are you looking for maximum or minimum R value.

Installation hints: Here is what we have found through our years of installing polycarbonate and the questions our customers ask us about installing polycarbonate. The biggest problem is an inadequate structure underneath the polycarbonate. It must be supported according to the manufacturers recommendations. It must be supported horizontally, which is by your purlins rather than your rafters. But, you still need both supports. For questions on this please see the manufacturers specifications. You do not screw through regular H's. You screw through the sheets when you are using a one piece H. When you are using snap H's or base and cap, you screw through the H's base and through the sheets. U's go at the top, bottom and finish the sides of the end sheets. At the bottom of the sheets you need to drill a small hole for drainage of any condensation which may occur. The foil tape goes at the top of the sheets under the U. The vented tape goes at the bottom of the sheets under the U. The flutes will run the length of the sheet. The sheets are available in 4' or 6' widths. Most manufacturers recommend a minimum of a 1 on 12 roof pitch. In other words for every foot you are coming forward, your roof slope should drop at least 1 inch.
Minimum Polycarbonate Order - $500.00 worth of polycarbonate sheets, this does not include U's, H's, screws, crating or shipping. As of May 1, 2011, we will be implementing a small order charge. Any order between $500.00 and $750.00 worth of polycarbonate sheets will be charged a $25.00 small order charge.
Please note: Shipping for polycarbonate is done by Common Carrier (trucking companies).
We will not cut sheets small enough to ship UPS. Any sheets under 6' length will have additional cutting charges. If you are looking for less than 8
sheets we would suggest Solexx as an appropriate substitute. It can be shipped UPS.
