Polycarbonate twinwall sheeting (also called multiwall) is the perfect glazing for any greenhouse application and many other construction applications. This material translates its many unique features into cost saving benefits for you. This is one of the heaviest sheets of this type in the industry and is manufactured in North America by the leaders in polycarbonate extrusion research and technology.

The surface of this material is protected from the degradation effects of UV radiation by a proprietary co-extrusion process. Beneficial infra-red light passes through the material promoting an ideal growth environment. In addition, the resins used to make this polycarbonate are specially developed for excellent flame retardant properties.

Effective heat loss reductions from polycarbonate when used instead of regular glass. Savings of up to 50% have been documented while using this glazing. Insulation values increase with thicker sheets, see standards table below.
