Rooflight Glazing Colour


The various glazing layers in Xtralite rooflights can be supplied in four types or colours: clear, opal, bronze or diffused—with the characteristics described below. For information on the light transmission of different types of polycarbonate rooflight glazing in various configurations, refer to the Properties of Glazing Materials and Configurations page. In addition, all ranges are ‘Non-fragile, Class B’ rating classified to ACR[M]001:2005 ‘Test For Non-Fragility of Profiled Sheeted Roofing Assemblies’, Edition 3 – the “Red Book”.

 

Clear Glazing

  • High light transmission.
  • Placement where glare may occur is a consideration.
  • Allows full vision of views and objects.

Diffused Glazing

  • Maximises privacy.
  • High levels of light transmission
    into a building.
  • Diffuses light transmission and so avoids glare and shadows.
  • Prevents vision of views and objects.

Opal Glazing

  • Maximises privacy.
  • Diffuses light transmission and so avoids glare and shadows.
  • Prevents vision of views and objects.

Bronze Glazing

  • Reduces solar heat gain.
  • Reduces light transmission into a building.

 

Alternative Rooflight Glazing Materials

 

Glass (IGL) Glazing

Offered in lieu of polycarbonate. Double glazed insulated glass units will provide
a low U value alternative. Selection of high specification glass can also be used to reduce such things as solar gain and rain noise whilst retaining non-fragile status. Contact Xtralite to discuss your requirements.
