Use polycarbonate sheets to construct the most rugged greenhouses and enclosed patios in areas known for severe weather or vandalism. Our 6mm and 8mm twin-wall polycarbonate panels offer high impact resistance, excellent heat retention and 80% light transmission. These panels block ultraviolet rays that burn plants and living tissues, only transmitting beneficial radiation. Avoid expensive shipping and crate charges by ordering Easy Ship 2-Feet Wide Twin-wall Polycarbonate Panels that ship via Standard Ground Service.

This double-wall polycarbonate is designed and engineered specifically for commercial greenhouse use and offers 99.5% UV protection. The two-wall design and light weight of the sheet means a reduced cost for the supporting structure since it doesn't need to support as much. Shatterproof polycarbonate coupled with integrated UV resistant co-extruded layer yields long service periods backed up by a 10-year limited warranty against yellowing from UV rays. The cellular multi-layer structure reduces heating costs in winter while minimizing excessive heat in summer. A special coating on the bottom side eliminates condensation dripping.

Whether you need clear twin-wall polycarbonate panels for a greenhouse, shed, pergola or outdoor pool, our easy ship sheets provide DIY usability with professional results. We offer lengths from 4 to 8 feet, letting you build all sorts of structures as-is or by cutting them to the right size and shape. You're backed by a 100% customer satisfaction guarantee and full support by phone or email.

They are very nice quality panels, however the description says 2’x4’ and they are 1/4” bigger on both.

Brian Motz (Pineville, US)
Best glazing

Strong and easy to work with. Shipped in less than a week when in stock. Joined together with "H" profile joiners and was still less money than ordering longer panels to cut down to size. Replaced the old 4 mm. panels that my Harbor Freight greenhouse came with.

R Hansen (Salt Lake City, US)
Order was exactly as described.

Shipping was quick and the product was just what we needed. Haven't had a chance to install the Twinwall Polycarbonate yet but I am suer it will hold up when I get to it.

Great product, easy to fit and delivered promptly

Jim J. (Seattle, US)

Used 4' sheets to re-glaze the roof of my greenhouse. Wasn't expecting the funny split edges that had to be trimmed off. About half of the 10 sheets were mashed on one side (no corresponding damage on the box). Worked OK because half of the sheets needed to be trimmed an inch on one side.

they replaced the old ones!

Fantastic panels

Replacing several of my old panels and these are far superior to what the greenhouse came with. Shipping was fast and everything reasonably priced.

Great greenhouse siding

Let's in a ton of light, easy to cut and work with. Sizing advertised is fairly accurate to within an inch.
