If you want to bring natural daylight into a room that doesn’t have any windows, then installing flat roof windows might be the best option. They are relatively new and might also be more efficient than other glazing techniques out there.
Flat roof windows (also known as flat rooflights) are never strictly “flat” – though they usually slope downwards by around 5° to aid with run-off – and visually they appear as such. They often obscure the view and aren’t particularly energy-efficient.
The main difference between flat rooflights and roof lanterns is that the latter is a 3D structure and the former is not. Roof lanterns provide more space to move about in whereas, flat rooflights do not.
