  • To suit a new timber ground – Code E: 160 mm high, for fixing to the of a newly constructed timber ground equal to or greater than the depth of the new insulation.
  • To sleeve over an existing curb or upstand – Code F: Manufactured to ensure ventilation modules and glazing do not foul the existing protrusions. Consult manufacturer for further information.
  • To suit an existing timber ground – Code G: Variable height for fixing to an existing builders kerb or plinth.

Glazing details:

- Material:

Double glazed insulating glass units offer a low U-value alternative to polycarbonate: selection of high specification glass can reduce solar gain and rain noise while retaining non-fragile status. Consult manufacturer for recommendations.

- Colour:

Available in four colours:

  • Bronze: Reduces light transmission and solar gain.
  • Clear: Offers high light transmission and allows full vision of views or objects.
  • Diffused: Offers high light transmission and prevents vision of views and objects.
  • Opal: Prevents vision of views and objects.

Security:

Xtralite offers a range of security options to prevent unauthorized access, depending on the level of security required.

  • Intruder grid (IG): 3 mm diameter, fully welded, steel mesh in a 75 mm grid which is fixed between the upstand and the roof structure. The grid will resist entry even when the rooflight has been compromised or removed.
  • Tamper resistant fixings (SS): Screws with inaccessible thread assemblies.
  • Security frame (SF): Robust, aluminium framing system that encloses and secures the outer edge of the glazing and clips onto the lower assembly.

  • Unventilated (00): Fixed rooflight, suitable for situations where ventilation is not required.
  • Hit and miss vent (01): Provides minimal background ventilation.
