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 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.

ROUGH OPENING PREPARATION

D. Apply sill ﬂashing tape #1. Cut a piece of ashing tape 12" longer

than the opening width. Apply at the bottom of the opening as

shown (1D) so it overhangs 1" to the exterior.

Note: e tape is cut 12" longer than the width so that it will

extend 6" up each side of the opening.

E. Tab the sill ﬂashing tape and fold. Cut 1" wide tabs at each

corner (1/2" from each side of corner) (1E). Fold tape to the

exterior and press rmly to adhere it to the water resistive barrier.
