I have a question about safety glass in windows. I know that the window has to meet 4 requirements in order for it to have to be safety glass.
- exposed area glazing >9sq feet
- bottom edge less than 18 inches
- top edge greater than 36 inches
- within 36 inches of a walking surface.
My question related to number one above.
Is the 9 square foot rule apply to a solid pane of glass similar to that of a sliding glass door or would a regular single or double hung window fall under this requirement also?
