What Size of Roof Window Should I Choose?
The size of the roof window should depend on the function and orientation of the room, the size of the floor space, and of course the personal preferences of the user.
Generally, we recommend that rooms used during the day should have more light than bedrooms.
Furthermore, take into consideration that roof pitches facing south generally get more light than those facing north due to the orientation of the sun.
As a rule, there should be a combined glazing area of at least 10% of the floor area.
