IS IT NECESSARY TO HAVE A RADIATOR/HEATER NEAR THE ROOF WINDOW?
Over the roof window, the interior lining should be horizontal (parallel with the floor) whereas it should be vertical below the roof window (perpendicular to the floor surface).
These precautions should be taken to ensure optimum flow of air and maximum light.
Be careful that a windowsill placed directly underneath the roof window does not obstruct the flow of air by leaving an air gap between the sill and the wall.
