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.


  • Dual glaze - 1/4" individual panes with 5/8" air space for 1 1/8" over all glass thickness (**standard product).
  • Triple glaze – 1 1/2" Over all glass thickness.
  • Single glazed - 3/8" thick glass.
  • Welded one-piece glazing frames.
  • Glazing frames factory installed.


When using true divisions, each glass of each piece of glass is separate, which reduces the square footage of the glass, thus making the glass thinner and ultimately reducing weight.

In addition to these advantages, the extra material contained in lamb or sticks does increase heat conduction, so a higher U factor is generated when calculating the unit value.


The advantage of the simulation mode starts with the improved NFRC U factor value.

Because the glass does not break multiple times, the heat resistance is improved, and the unit value has a better performance value.
