1 ROUGH OPENING PREPARATION
A. Confirm the opening is plumb and level.
Note: It is critical that the bottom is level.
B. Confirm 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.
C. Cut the water resistive barrier.
D. Fold the water resistive barrier. Fold side flaps into the
opening and staple to the inside wall. Fold the top flap
up and temporarily fasten with flashing tape.
E. Apply sill flashing tape #1.Cutapieceofashing12"
longer than the opening width. Apply at the bottom of
theopeningasshownsoitoverhangs1"totheexterior.
Note: The tape is cut 12" longer than the width
of the opening so that it will extend up each side
approximately 6".
F. Tab the sill flashing tape and fold.Cut1"widetabsat

G.Apply sill flashing tape #2. Cut a piece of flashing tape

Note: The flashing tape does not need to extend all the
way to the interior of the framing.

Make an 8" cut up from
each top corner at a 45°
