3 INTEGRATING THE WINDOW TO THE WEATHER RESISTIVE BARRIER A. Apply side flashing tape. Cut 2 pieces of flashing tape 4" longer than.the frame height of the window. Apply one piece to each side over the nailmg fin and onto the weather resistive barrier. The tape should extend 2" above the top of the window and 2" below the bottom of the window. Press the tape down firmly. B. Apply top flashing tape. Cut a piece of flashing tape long enough to go across the top of the window and extend at least I" past the side flashing tape on both sides. Apply the tape over the top nailing fin as shown. Press the tape down firmly. Note: DO NaT tape or seal the bottom naRing fin. C. Fold down top flap of weather resistive barrier (3C). D. Apply flashing tape to diagonal cuts. Cut pieces of flashing tape at least I" longer than the diagonal cuts in the weather resistive barrier. Apply the tape, covering the entire diagonal cut in the weather resistive barrier at both upper corners of the window. Press the tape down firmly. Note: Be sure to overlap the top corners (3D).

Use of high pressure foams or improper application of the foam may cause the window frame to bow and hinder operation. A. Apply insulating foam sealant. From the interior, insert the nozzle of the applicator approximately I" deep into the space between the window and the rough opening and apply a I" deep bead of foam. This will allow room for expansion of the foam and will minimize squeeze out. Allow the foam to cure completely (usually 8 to 24 hours) before proceeding to the next step. Note: It may be necessary to squeeze the end of the tube with pliers to be able to insert into the space between the window frame and the rough opening. DO NOT completely fiU the space from the back of the fin to the interior face of the window. B. Check window operation by opening and closing the window. Note: If the wJndow does not operate correctly, check to make sure it is stJ/I plumb, level, square and that the sides are not bowed. If atfJustments are required, remove the foam with a selTBted knife. AtfJust the sblms, and reapply the insulating foam sealant.
