Additional Information


Rectangular double-ended roof lights with a width from 500 to 4000mm and a length from 750 to 5850mm, 25 degree fixed pith to all sides, glazing bar top caps in chambered PVC.

Thermally broken aluminium ridge body.



Low profile eaves beam (no gutter) designed to be fitted with over sailing 24mm double glazed units (high performance low e, self-cleaning and solar control in blue or neutral clear).


Ultrasky is designed around maximum uninterrupted sight lines, bar numbers are reduced (or can be added if you prefer) and the ridge board and hub ends are as unobtrusive as possible.


The thermal performance has been optimised to make it suitable for extensions in domestic properties. Typical U value with 1.1 glass for a 1000mm wide x2000mm long rooflight is 1.4 W/m2K.


Choose the stylish White PVC option to match your modern window frames, or for that extra “Wow” factor go for the Aluminium option, available in White, Anthracite Grey or Satin Black. Internally the rooflight is clad in white PVC or upgraded to anthracite grey or satin black to either match or contrast the external finish.


Add a roof vent to let in the fresh air – Roof vents are available with a manual opener, automatic opener or an automatic opener with rain and temperature control. * (roof vents only available in selected sizes).
