VELUX top-hung roof windows - The perfect choice for loft conversions and attic renovations. The sky is the limit with a top-hung roof window. Operated with a handle at the bottom, VELUX top-hung roof windows give you a full, unobstructed view of your skyline and maximise the amount of natural daylight that can be allowed in. We recommend top-hung roof windows for loft conversions with in-reach installations, where you have to, or wish to, place roof windows in easy reach. The bottom handle allows you to open the window outwards and gives you an unobstructed view and feeling of extra space. Examples include above-garage bonus rooms, lofts, and finished attic spaces. They can be opened to any position up to 45 degrees allowing you to take advantage of uninterrupted views and a feeling of extra space.
