Roof Window (Velux)

A window installed within a pitched roof slope, flush with the roof surface, allowing light and ventilation into a loft space. The brand name 'Velux' is commonly used generically for roof windows. Roof windows are typically permitted development in loft conversions (rear only, not projecting beyond the roof slope) and require a flashing kit to weather the junction with the tiles.
