Custom Glaze




Alsynite Custom Glaze is a great looking, flat, polycarbonate roofing product. It’s designed to look similar to a glass or acrylic roof, without the cost or complicated installation system.


  • 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: Care must be taken during installation to ensure the sheets are pulled taught, and overlapped correctly. This is so you don’t get a bow or ripple effect in them. They are more difficult to install than a standard corrugate profile, and usually require two people. It’s also 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.
