Ridge Window

Keylite Ridge (RG) roof windows may be installed along the roof ridge to maximise light and space at the highest point of the pitched ceiling and create a striking feature.


Year Guarantee

Keylite RG roof windows are ideal for both domestic and commercial applications, and are available for the following ranges: Centre Pivot (CP), Top Hung (TH), Conservation (CW) and White Finish (WF) Roof Windows all with the option of an Integral Blind (I).

  • Usually installed in out-of-reach locations, these roof windows may be electrically operated by hand-held remote control or a wall-mounted switch.
  • The installation of Keylite RG Roof Windows is very similar to standard roof window installation.
  • The roof windows must be positioned in a way to avoid opening without the sashes colliding.
  • Keylite RG roof windows that are positioned 280mm or greater below the ridge can be fitted using standard Keylite Flashings.
  • Windows that are positioned less than 280mm will require Keylite RG Flashings.
