VELUX roof windows

Opening Rooflight

Enjoy symmetrical style with a statement square window that casts a beautiful, ever shifting light into your home. Dare to dream big, go for a large size and elevate your square window to appear almost as a glass ceiling, providing a powerful connection with the outside world. Alternatively, plan a smart pattern of smaller squares that will lend a charming dappled daylight effect to any room. The square one can easily be installed almost anywhere in your house, allowing for a very flexible, functional window to the wider world. It can also come with a huge array of helpful features, such as highly insulating glass, motorised ventilation, walk-on capability for roof terraces and other great custom features.
