Reading Window Schedules Like a Pro
The window schedule is one of the most important tables on your construction drawings. It's where architects translate wind load calculations into actual product specifications. Every window in your building has a row in this table.
TAG (W1, W2, etc.)
Links to floor plan markings. Find "W1" on the floor plan, and this row tells you everything about that window.
SIZE (Width x Height)
Rough opening dimensions. Larger windows = higher total wind load, which can affect pressure rating requirements.
PRESSURE (+/-PSF)
THE critical column for wind zones. These are the ratings the window MUST meet or exceed. Positive pushes in, negative pulls out.
IMPACT Rating
In Monroe County, all windows must be either impact-rated OR protected by approved shutters. Impact windows can resist flying debris.
When ordering windows for Monroe County, always give your supplier the PRESSURE column values. They need both the positive AND negative numbers. If a window only meets the positive requirement but fails the negative, it will not pass inspection.
