X-Glaze Polycarbonate Glazing

 

The X-Glaze rooflight range provides single, double or triple skin polycarbonate glazing units for direct fixing to a builder’s kerb or upstand. As there are no integral frames or kerbs, the usual range of Xtralite ventilation, access and other options are not available. Also, the U value provided applies to glazing only, as—for Building
Regulations purposes—the builder’s kerb or upstand forms an integral part of the
roof not the rooflight.

Polycarbonate 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 Designing with Daylight section. 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.

 

Security


Xtralite offers a range of security options to prevent unauthorised access, depending on the level of security required and product range selected.

 

Security Screws (SS)

Intruder Grid (IG)

Intruder grid systems may be added to all rooflights in the Xtralite range. They are positioned between the upstand and the roof structure and consist of a 3 mm diameter, solid steel fully welded mesh in a 75 mm grid. This system will resist entry even when the rooflight has been compromised or removed.
