The Velux Velta skylight is an access window designed to provide ventilation and light for uninhabited and unheated loft spaces. It enables easy access to the roof and provides good lighting. Velux Velta skylights are produced with 15 mm double glazed pane to improve insulation. They come with integrated flashing, eliminating the need for a separate installation product, and fit perfectly on tiles and slates. The skylight can be installed perfectly on slates too after removing or trimming the foam gasket. The construction is easy to fix and mount in the roof area. Velux Velta windows are designed for maximum flexibility; they can be installed as side-hung left or right.
