I plan on converting my deck to a 3 season room / sun room.
How low can the window sills be? I've heard anything lower than 18" requires safety glass.
If that's true I would probably use fixed windows along the bottom and have sliding windows above them. Are the fixed windows called Transom Windows? Not may of the home stores list fixed windows so maybe I'm using the wrong name?
R312.2.1 Window sills.
In dwelling units, where the opening of an operable window is located more than 72 inches (1829 mm) above the finished grade or surface below, the lowest part of the clear opening of the window shall be a minimum of 24 inches (610 mm) above the fininshed floor of the room in which the window is located. Operable sections of windows shall not permit openings that allow passage of a 4-inch-diameter (102 mm) sphere where such openings are located within 24 inches (610 mm) of the finished floor.
Exceptions:
1. Windows whose openings will not allow a 4-inch-diameter (102 mm) sphere to pass through the opening when the opening is in its largest opened position.
2. Openings that are provided with window fall prevention devices that comply with ASTM F 2090.

For SI: 1 inch = 25.4 mm, 1 square foot = 0.0929 m2.
