I'm missing something and I'm sure it's simple.
In chief when I dimension a window it seems to dimension the glass.
I am a supplier as well and when I build a window in my window manufacturers software it references the outside of the frame as well as tip to tip and rough openings required.
Is there a way to build a 24" x 24" window that means 24" is outside of frame requiring a 25 1/4" Rough opening?
Thanks in advance.
