Idelite Standard rooflight is a fibreglass reinforced translucent panel manufactured from UV stabilized unsaturated polyester resin system reinforced with high quality glass fibre to ensure weather ability.

Key Benefits:

  • Manufactured from a modified resin system, reinforced with high quality glass fibre roving.
  • Encompasses built-in UV inhibitors which prevents early degradation, yellowing and embitterment of the sheet;
  • Oven cured and profiled to ensure maximum binding and strength.
  • Incorporates special light diffusing additives which scatter light passing through .This is particularly important to ensure good light distribution and to reduce glare and excessive shadow.
  • An extremely flexible product providing unique variation to meet design criteria.


  • Commercial, industrial, institutional and other projects where long term high quality lighting is required;
  • School/Kindergarten and public outdoor areas requiring excellent protection.

Special Applications:

  • IDELITE can be supplied tinted with variations to reduce light and heat transmission. This is recommended due to the long term clarity of the sheet.
  • IDELITE can be supplied as fire retardant sheeting


Sheets are sold by weight –kilograms per square meter – rather than thickness. As the sheets are made heavier (thicker) they become stronger.

The most popular range of weight (Grade) is 1730 g/m, 2100 g/m2, 2440 g/m2 and 3500 g/m2. Other grades are also available upon request


IDELITE is available in standard colours of Clear, White Tint, Opale, Blue and Blue green. Other colours are available upon request to suit specific design applications.
