How to read it
The Navy's Builder 3 & 2 course calls these stationary windows: a sash with a large single pane, fastened permanently into the frame, and often set beside windows that do open. With nothing to move, the symbol shows no motion. Under the A/E/C Graphics Standard each window also carries a mark inside a diamond, and the same mark appears in the window schedule, which lists the exact unit.

This explains what a symbol represents on a drawing. Conventions vary between firms and standards, and a drawing's own legend takes precedence.
Look-alikes
The sliding window and double-hung window are also drawn without a swing. The window mark and schedule tell them apart when the linework doesn't.
