Window schedules
Window frame manufacturers produce a range of readily available frames. Their sizes are detailed on a schedule. A typical schedule details the appearance of the window frame when viewed from the outside. It also shows the finished height and width of the frame. The height is usually shown to the left of the page and the width is shown across the top. Most schedules also show the stud opening size required. When specifying the dimensions of a window frame, the height is always written first.
The height and width opening sizes are checked to determine an appropriate window.
