What Thickness of Corrugated Polycarbonate Sheet Is Recommended for Hurricane Resistance?

For projects located in areas with strong wind loads or hurricane exposure, GWX generally recommends using corrugated polycarbonate sheets with a thickness of at least 1.5mm. Thicker sheets typically provide better rigidity, impact resistance, and overall structural stability under extreme weather conditions.

However, the hurricane resistance of a roofing system does not depend solely on sheet thickness. The overall roof structure design is the most critical factor in determining wind resistance performance. Even high-quality roofing sheets may fail under severe weather conditions if the supporting structure, fixing method, or installation design is inadequate.

For hurricane-prone regions, it is important to combine appropriate sheet thickness with a professionally engineered support structure and proper installation practices. In many cases, additional reinforcement measures may also be recommended depending on the project location and expected wind pressure.

At GWX, we can provide product recommendations based on your application environment, roof structure, and project requirements. Customers are encouraged to share roof drawings, installation details, or local wind resistance standards so our team can recommend suitable sheet specifications and supporting solutions more accurately.
