With a minimum 3 diploma fall, character droplets of water will nevertheless live at the glass as they could on vertical glazing, but larger pools of water will not form.

In all glazing there is a diploma of flex or ‘deflection’ this is in particular obvious on overhead glazing. A combination of wind load, snow load and the bodily self-weight of the glass all make a contribution to the quantity of deflection this is obvious. The glass rooflight specification ought to be calculated so that the most quantity of deflection under the worst case loading and on the largest pane sizes does not exceed 25mm.
