Polycarbonate Panels

One of the strongest greenhouse coverings, polycarbonate, is a rigid plastic that is almost as transparent as glass. It is available in corrugated single layer or flat twin-wall thicknesses, and is easily cut and installed. The air pockets between the two walls act as an insulator and light transmission is very good through this material. Whether you're building a greenhouse or replacing existing greenhouse covering, Growers Supply offers the ideal polycarbonate for your project. Our corrugated polycarbonate can also be used for carports, deck and patio coverings, privacy windows, room dividers, pool enclosures and more.
