Lightweight Alternative to Glass

Polycarbonate is considerably lighter and easier to handle than traditional glass while providing excellent impact resistance for outdoor roofing applications.

The sheet can be cut to the required size and installed using compatible polycarbonate glazing bars, end closures, sealing tapes and suitable fixings.

UV Protected Polycarbonate Roofing

The sheet incorporates UV protection for exterior use, helping protect the polycarbonate against degradation caused by prolonged exposure to sunlight.

For the best long-term performance, install the sheet with the UV-protected face positioned towards the outside of the roof and follow the correct installation instructions.

Installing 10mm Twin Wall Polycarbonate

The internal channels of the sheet should always run down the direction of the roof slope so that condensation within the channels can drain correctly.

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

Clear, Bronze or Opal Polycarbonate?

Clear polycarbonate is the best choice where maximum daylight is the priority.

Bronze polycarbonate provides a tinted appearance and helps reduce glare and solar brightness, while Opal polycarbonate produces softer, diffused natural light beneath the roof.
