Custom Glaze



Custom-Glaze-flat-polycarbonate-roofing-logo-newAlsynite Custom Glaze is a great looking, flat (with joining ridges), polycarbonate roofing product. It’s designed to look similar to a glass or acrylic roof, without the cost or complicated installation system.

This is one of our favourite products. It's easy to install, looks much better than corrugate, and is much cheaper than a solid flat glazing system.

  • Not available for pick up (sent direct from factory) - delivery available nationwide (click here for delivery map)
  • Overlapping ribs at 610mm centres (usually hidden by the rafters), eliminating the need for expensive glazing systems
  • Purlins at 1500mm apart allowing a greater flat, clear area
  • A full flat pan of 540mm, giving a solid flat look without corrugations
  • 2mm thick
  • 99.9% UV protection
  • NZBC Fire group rating 1-S
  • 20 year weather breakage and 15 year loss of light warranty

Note: It’s important that they have at least a 5 degree fall, the steeper the better, they are still quite flexible. Sheets also have a 5mm width tolerance (i.e. coverage could be 605mm or 615mm) so best to measure them first, before installing the rafters (if you're wanting to hide the joins with rafters).
