Twin Wall Polycarbonate Sheet

Twin-wall polycarbonate sheets have an inner rectangular insulation space that reduces heat transfer. At the same time, it creates a stronger, lighter, and more impact-resistant structure. Due to the co-extruded UV coating, twin-wall polycarbonate sheets have excellent weather resistance even under strong UV exposure, and the service life can reach 15 to 20 years or even longer.
