PROFILED POLYCARBONATE SHEET

Profiled Polycarbonate Sheets (often called Corrugated Polycarbonate) are the professional’s choice for integrating natural light into metal or fiber-cement roofing systems. Designed to match standard industrial profiles, these sheets provide a seamless, leak-proof lighting solution that combines the strength of polycarbonate with the structural rigidity of a corrugated shape.

Key Features & Benefits

  • Profile Matching: Engineered to match most common metal roofing profiles (Sinus, Greca, Trapezoidal), allowing for easy integration without complex flashing.

  • High Impact Resistance: Virtually unbreakable—tested to withstand heavy hail, falling debris, and extreme weather conditions.

  • Maximum Light Entry: Provides high levels of natural illumination, reducing the need for artificial lighting during the day.

  • UV Protection: Equipped with a high-performance UV-protective layer that filters out 99.9% of harmful rays while protecting the sheet from aging.

  • Low Maintenance: The corrugated shape facilitates natural cleaning; rainwater washes away dust and debris more effectively than on flat surfaces.

  • Cost-Effective: Lightweight and easy to handle, reducing labor costs and the need for heavy-duty support frames.

Common Applications

Sector Common Uses
Industrial Factory roof lights, warehouse skylights, and side-wall glazing.
Agricultural Greenhouse roofing, poultry farm lighting, and barn windows.
Residential DIY patio covers, carports, deck roofing, and sheds.
Commercial Sports stadium canopies, walkway covers, and outdoor markets.



Installation Best Practices

  • Overlap Direction: Always install the overlap facing away from the prevailing wind direction to prevent water ingress.

  • Fastening: Use EPDM-integrated “Storm Washers” to distribute pressure evenly and ensure a watertight seal at the fixing points.

  • Pre-Drilling: Always pre-drill holes 2mm–3mm larger than the screw diameter to allow for thermal expansion.

  • Minimum Pitch: For effective water runoff, we recommend a minimum roof pitch of 5° to 10°.
