Check with your window supplier as to what sizes are best suited for fire egress windows in bedrooms to meet code.

2nd Floor Window Dormer - Recommended Window Sizes. Window height is based on 7’6″ first floor ceiling height in the 22′, 27′, 30′ & 34′ domes. Window height is based on 8′ ceilings on the first floor for the 36′ or larger domes. Both are based on 2×10 second floor framing. Increase height 2″ for 2×12 framing. To have a bedroom on the second floor of a 34′ dome, a fire egress casement window is installed in a door dormer NOT a second floor window dormer. To have a door dormer on the second floor there must be a standard entryway below it. The maximum size window is 2’6″ x 5′ tall (needs to be tempered glass because window will be within 18″ of the floor). The minimum size window to meet bedroom fire egress is a casement 2’6″ x 3′.A Second Floor Door Dormer can only be installed above a standard entryway. Due to the panel sizes in a 34′ dome, the second floor door dormer can only accept a custom door two feet wide by six feet tall. Because of such a small door, this is why our web site states a second floor door dormer is not available on the 34′ dome. However a second floor door dormer in a 34′ dome could be used to accept the reguired fire egress window. This can be confusing, so please call for clarification…..321-639-8777. |

| Cupola windows can not qualify for egress because they are too high above the floor. Two standard vinyl horizontal roller or slide type windows are needed to fill one rough window opening of a cupola. They can be installed with a mullion in between them or custom windows can be installed. | ||||||
| Florida and most other state’s code for Glass and Glazing requires tempered glass to be used in windows whose nearest edge is within 24″ radius of a door in closed position. Tempered glass is also required for glass panes with a bottom edge less than 18″ and a bottom greater than 36″ above the floor. | ||||||
Maximum Rough Opening Sizes for Doors and/or Windows
Our Entryways and Dormers provide openings in the dome that accommodate conventional doors and windows that you purchase locally. The walls within these openings are built on-site to fit your choice of door and window sizes.
Typical heights (distance “D” from the floor to the top of the opening) are listed in the first column with the maximum available rough opening listed for each dome size.
Opening sizes are listed as Width x Height.
