Opal Polycarbonate for Diffused Natural Light

Opal polycarbonate allows natural daylight through while spreading the light more evenly beneath the roof. This helps reduce harsh glare and creates a softer, brighter and more comfortable covered area.

It is particularly suitable for patios, seating areas, pergolas and south-facing installations where clear polycarbonate may allow more direct sunlight than required.

Strong & Lightweight Polycarbonate Roofing

Polycarbonate provides excellent impact resistance while remaining considerably lighter and easier to handle than traditional glass. The twin wall construction adds rigidity and creates an insulating air space within the sheet.

For open-sided structures where high levels of thermal insulation are not required, 10mm twin wall polycarbonate provides a practical and economical roofing solution.

UV Protected for Exterior Use

The sheet incorporates UV protection to help protect the polycarbonate against degradation caused by prolonged exposure to sunlight.

For the best long-term performance, always install the sheet with the UV-protected face towards the outside of the roof.

Installing 10mm Twin Wall Polycarbonate

The internal channels of the sheet should always run down the direction of the roof slope. This allows condensation within the sheet structure to drain correctly.

The sheet ends should be finished using suitable sealing and breather tapes together with compatible end closures. Appropriate polycarbonate glazing bars should be used between sheets, with sufficient allowance made for thermal expansion and contraction.

Clear, Bronze or Opal Polycarbonate?

Clear polycarbonate is ideal where maximum natural daylight is required. Bronze polycarbonate provides a tinted appearance and helps reduce solar glare, while Opal polycarbonate provides softer, diffused daylight and greater visual privacy.
