Polycarbonate (PC) is one of the most ideal materials for skylights, especially excelling in scenarios requiring a balance between light transmission and strength.

Core Advantages: This material, known as “unbreakable glass,” boasts an impact resistance more than 250 times that of ordinary glass, easily withstanding physical impacts such as hail and falling objects. Its weight is only half that of glass, significantly reducing the load on the supporting structure, making it ideal for large-span industrial plants, awnings, and greenhouse roofs.

Application Recommendations:

Hollow Sheets (Multi-layer Sheets): If you prioritize thermal insulation, hollow structures effectively trap heat, suitable for sunrooms or greenhouses.

Corrugated Sheets/Trapezoidal Sheets: This structure offers higher drainage efficiency and stronger wind pressure resistance, commonly used for industrial warehouse or garage roofs.

Thickness Selection: For roofing, solid sheets are recommended to be at least 3mm thick, while hollow sheets are recommended to be at least 10mm thick to ensure sufficient structural rigidity.

If you decide to use PC (polycarbonate) sheets for your roof, be sure to choose sheets with single-sided or double-sided UV co-extruded layers. Sheets without a UV layer will yellow and become brittle within two years when exposed to direct sunlight, and may even break easily with a touch.
