The Nominal size of a window is really the size needed for the rough opening. The real size of a window is its exact size (from one side of the frame to the other, horizontally then vertically).

Thick glass is far more durable and less likely to break, naturally enhancing the structural stability of our windows, greatly enhancing sound control.
