B. Verify the window will ﬁt the opening. Measure all four sides of the

opening to make sure it is 3/4" larger than the window in both width
and height. On larger openings measure the width and height in several

Note: 1-1/2" or more of solid wood blocking is required around the
perimeter of the opening. Fix any problems with the rough opening
before proceeding.
