Transform your home with daylight.

Brighten any room with the VELUX 3in1 roof window. The unique design of the 3in1 roof window invites beautiful daylight into your home and opens up wide, panoramic views. The 3in1 roof window offers you the best deal on daylight too. With three individual sashes set in a single sleek frame, it is more cost-effective than purchasing three individual roof windows of the same size.

The 3in1 roof window is the new standard for more daylight and fresh air. A 3in1 roof window is ideal for medium to large rooms or you can combine them with more windows if you have a bigger room.

The 3in1 roof window is designed to maximise the amount of daylight in your space as the slim profiles increase the amount of daylight entering the room. 
The new 3in1 roof window is available in two different window sizes and you can choose between manual or solar windows to suit your home and needs.

For roof pitches: 15°-90°
  • Most affordable way to maximize your daylight
  • Wide panoramic view to the outside
