We recently installed this Velux 550×980 Skylight (manual opening) in an upstairs attic room because it would give both ventilation & light. By the way at SVSLs (Skyvac Skylights), we make our own custom flashing for Velux Skylight for metal roofs. Darren our ‘sheetie’ is old school & gets it millimetre perfect. All were happy with the job.
