4mm Black Twin Wall Polycarbonate Sheet
Product Introduction
Twinwall polycarbonate from Hebei UNQ provides an endless range of glazing and roofing applications, for extreme weather conditions, and is known for its light-transmitting and reflective qualities. Twinwall is attractive, durable, easy to install, and has the impact resistance and UV protection to withstand anything you can throw at it. Twinwall's notorious double paneled sheets serve to trap air, therefore increasing the product's insulation strength. Insulation properties will increase depending on the material's thickness.
Twinwall's surface is protected from the degradation effects of UV radiation by a proprietary co-extrusion process. Beneficial infrared light passes through the material promoting an ideal growth environment. UV-resistant Twinwall is twelve times lighter versus glass and the resins comprising the material are specially developed for excellent flame retardant properties.
