The divisions in the glass are one of the design elements that never seem to lose popularity. For centuries the divided lite patterns in a window or a door have been inherent to the design of the architecture.
There are two primary ways to divide the glass today. There is still a true division of the glass using multiple individual lites or there is a simulated division that can be used to create a similar appearance with better energy values. There are advantages with both approaches and each have different merits.
