The Rectangular Roof Lantern
Visually very pleasing, this is without doubt our most popular arrangement for inclusion over a living space. The rectangular roof lantern lends itself to being placed centrally within the ceiling over a rectangular space or to define a specific domestic function within a larger open plan area.
Provided that the difference between its X and Y plan dimensions is no less than 500mm (ideally greater), then it can accommodate ridge mounted ventilators.
