Mullions explained
A mullion is the point where a window panel finishes. You can customise it to suit your liking or leave it as is (for an even window panel distribution/style).

Below are examples of different window styles and from which points the mullions are calculated to and from:

External Cill
85mm Sub Cill
This compact cill has minimal overhang designed primarily for installations where space is limited, ideal for directing water away from the building façade and ensuring effective drainage in smaller setups.
150mm Sub Cill
The 150mm cill is commonly used across residential and commercial installations. It provides enhanced protection by directing water further away from the wall surface, helping prevent moisture accumulation.
180mm Sub Cill
The 180mm cill has a generous overhang, ideal for installations that require robust weatherproofing. This extended overhang is particularly suitable for high-exposure areas, offering superior water deflection.
