<br />1 ROUGH OPENING PREPARA liON <br /> <br />A. Verify the opening is plumb, level and square. Ensure the bottom of the <br />rough opening does not slope toward the interior. <br />Note: Do not install in out-of-square opening or on a surface that is <br />not level <br /> <br />B Verify the window will fit the opening. Measure all four sides of the opening <br />to make sure it is 1/2" larger than the window in both width and height. On <br />larger openings measure the width and height in several places to ensure the <br />header or studs are not bowed. <br />Note: 1-1/2" or more of soOd wood bloddng 1s required around the <br />perimeter of the opening. Flx any problems with the rough opening <br />before proceeding. <br /> <br />C.

Fold side and bottom flaps into <br />the opening and staple to inside wall. Fold top flap up and temporarily fasten <br />with flashing tape. <br /> <br />E. Apply sill flashing tape #1. Cut a piece of flashing tape 12" longer than <br />the opening width. Apply at the bottom of the opening as shown (IE) so it <br />overhangs 1" to the exterior. <br />Note: The tape 1s cut 12" longer than the width so that it wiD extend 6" <br />up each side of the opening. <br /> <br />F. Tab the sill flashing tape and fold. Cut 1 " wide tabs at each comer <br />(112" from each side of comer) (IF). Fold tape to the exterior and press <br />fkmly to adhere it to the weather resistive barrier. <br /> <br />G. Apply sill flashing tape #2. Cut a piece of flashing tape 12" longer than the <br />opening width. Apply at the bottom, overlapping tape #1 by at least 1". <br />Do not allow the tape to extend past the interior face of the framing (1 G). <br />Note: The Dashing tape does not need to extend all the way to the lnterior <br />of the /Taming. <br /> <br /> <br />@ <br /> <br />=p~~ <br />, Interior <br /> <br />@ <br /> <br /> <br /> <br />@ <br /> <br />--- <br /> <br />---- <br /> <br />---....- <br /> <br />........ _I <br /> <br />
