VELUX conservation roof windows


For traditional buildings


When planning dictates that a window of traditional external appearance is required, conservation roof windows should be considered. All of our conservation roof windows have the same technical features of a VELUX roof window but in a traditional black conservation style.

What does a conservation package include?

  • Roof window with pre-fitted glazing bar.
  • Laminated safety glazing as standard.
  • Insulation collar and underfelt collar provided for a weathertight and energy efficient installation.

Optional glazing bars for standard VELUX roof windows

Depending on where you live, conservation officers will have different requirements. The black finish featured in our conservation roof window packages may not be required in your area.


By adding a glazing bar to a standard VELUX roof window with a grey exterior, you can create a traditional appearance, allowing you to take advantage of all roof window styles and sizes available (except triple glazed roof windows).


Recessed flashing

In addition to a glazing bar, you may be asked to install your roof window deeper into the roof than can be achieved with standard installation. To do this you should select a recessed flashing kit, streamlining the roof window so less protrudes above the roofline.


Recessed flashings are also available with insulation and underfelt collars and are recommended for optimum energy efficiency. Our full range of recessed flashings are available as part of our conservation roof window packages.
