Ft Worth Egress Code
Safety Glass (Laminated or Tempered) glass is required for windows that are within eighteen inches of the doors vertical edges when the door is in a closed position. It is also required in windows that are within eighteen inches of the floor, but only if that piece of glass is larger than nine square feet in size. Safety Glass is also required for glass that is within 60 inches of a bathtub or shower drain or “in the vicinity of” a pool area. For this reason many builders and re-modelers use operating windows that are “oriole” in style. An Oriole is a single or double hung window that has a smaller bottom sash than top sash. These are usually split up as 60% on Top and 40% on the bottom. By doing this even a large 40 X 78 window can still be used in a close to the ground application without safety glass.
