Product Portfolio Continuous Rooflights

Continuous Rooflights

 

Xtralite Continuous Rooflights have been introduced for fast-track procurement of linear rooflight systems up to 2.4 m wide. For larger continuous rooflights—or those with corners or other complexities—refer to the Specialist Roof Glazing page.

Three design formats are available:

  • Thermoformed Barrel Vault
  • Linked Pyramids
  • Linked Domes

Guide Sizes (width mm)
600 900 1200 1500 1800 2100 2400

 

Continuous Rooflights are triple glazed as standard and formed from enhanced UV-protected polycarbonate with vented airspaces to satisfy Part L requirements. Single- and double-skin glazing options (which fall outside Part L) are also available. The integral Cascade water management system ensures that moisture drains to
the outside of the building and air leakage meets Part L criteria.

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 page: Designing with Daylight—Properties of Glazing Materials. 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.

 

Rooflight Security Options


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.
