Twin-wall polycarbonate sheet, a standard version of multiwall polycarbonate sheet, is self-supporting without requiring as many grazing bars as floating glass, for the weight of polycarbonate sheet accounts for only a quarter of glass. Light weight and hollow structure together contributes to cost saving and high light transmission.

Features:
-
High light transmission
Light transmission of 4 mm clear twin-wall polycarbonate reaches 89%. Twin wall polycarbonate sheets are often used in greenhouse not only for sufficient sunlight, but also blocking out harmful UV radiation.
-
High impact strength
Impact strength of polycarbonate sheet is 250 times as much as the size of tempered glass. This superiority makes it an optimum material for protecting greenhouse from hail and stones.
-
Saving energy
Twin-wall construction optimizes thermal insulation. In hot summer or cold winter, the ambient temperature below polycarbonate sheets will not intensively change and keep a relative stable state.
-
UV protection
Coextruded UV layer can absorb 98% UV rays, reducing UV damage to people, plants, organics and polymers. The UV protective layer is 50 μm in thickness, which veritably blocks UV rays out and create a safe environment.
-
Sound insulation
Twin wall polycarbonate sheets are premier sound-proofing material for highways throughout the world. The capability of sound insulation is determined by hardness, weight and physical structure. For example, twin-wall polycarbonate sheets reduce the sound intensity about 19 db to its maximum extent.
-
Anti-drip
A special hydrophilic coating on the inner surface spoils the formation of condensation droplets, hence the loss of light transmission will not rise. Commonly, when the outdoor temperature is 0 °C and the indoor is 23 °C, the surface of multiwall polycarbonate sheet will not create droplets only if the room humidity is below 80%.
-
Aesthetic appearance
Twin-wall structure adds an aesthetic element to the properties, the public buildings and other places where the sunshine not the UV ray is required.
