Roof windows side-by-side

Read more Read less

Where there is room for one roof window, there is often room for two.

The VELUX side-by-side combination features two adjacent roof windows that give your room an enhanced feeling of spaciousness, double the amount of daylight, and widescreen views of the world outside.

A side-by-side roof window is ideal for small and medium-sized rooms or you can combine them with more windows if you have a bigger room.

The side-by-side roof window is available in various window sizes. You also have the option of manual, electric or solar powered windows to suit your home and needs. A white maintenance-free finish is recommended for a durable and robust surface.

Suitable for roof pitches: 15°-90°
  • Expansive views with more daylight
  • Increases feeling of spaciousness
