Are roof lanterns noisy when it rains?
A frequent worry with roof Lanterns is the noise levels when it rains. However, an effective design reduces the levels of noise from rain and other external noise! The more glass panes utilised in the design of a Lantern, the lower amount of external noise there is, and the more distance between the glass panes, the better the sound insulation will be. Denser glass panes will also help in decreasing the overall noise levels.
