ROUGH OPENING PREPARATION
A. Verify the opening is plumb and level.
Note: It is critical that the bottom is level.
B. Verify the window will fit the opening.
Measure all four sides of the opening to make
sure it is 1/2" larger than the window in both
width and height. On larger openings measure
the width and height in several places to ensure
the header or studs are not bowed.
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.
D. Fold the water resistive
barrier (1D). Fold side
flaps into the opening
and staple to inside wall.
Fold top flap up and
temporarily fasten with
flashing tape.

E. Apply sill flashing tape #1. Cut a piece of flashing tape 12" longer than
the opening width. Apply at the bottom of the opening as shown (1E)
so it overhangs 1" to the exterior.
Note: The tape is cut 12" longer than the width so that it will extend
6" up each side of the opening.
