45 <br />STEP 1: <br />A. MAKE AN "I -CUT" (STANDARD i-CUT) IN THE <br />WEATHER -RESISTIVE BARRIER (30# FELT). A MODIFIED <br />I -CUT IS ALSO ACCEPTABLE. BEGIN WITH A HORIZONTAL CUT <br />ACROSS THE TOP AND BOTTOM OF THE WINDOW OPENING. <br />AT THE CENTER OF THE WINDOW OPENING CUT STRAIGHT <br />DOWN FROM THE TOP TO THE WINDOW SILL. <br />WEATHER -RESISTIVE BARRIER SHOULD BE REMOVED FROM <br />TOP OF SILL PLATE. <br />B. CUT TWO 45 DEGREE SLITS APPROX. 6"-8" EXTENDING <br />FROM THE CORNER OF THE WINDOW HEAD, UP AND AWAY <br />FROM THE WINDOW OPENING. THIS WILL CREATE A FLAP <br />ABOVE THE ROUGH OPENING TO ALLOW HEAD FLASHING <br />INSTALLATION. FLIP HEAD FLAP UP AND TEMPORARILY <br />SECURE WITH TAPE. <br />C. FOLD SIDE FLAPS INTO ROUGH OPENING AND SECURE TO <br />INSIDE WALL. FLAPS SHOULD EXTEND TO INSIDE EDGE OF <br />WINDOW FRAMING. CUT OFF EXCESS FLAPS AS DESIRED. <br />iORIZONTAL CUT <br />VERTICAL CUT <br />JT <br />SECURE HEAD FLAP <br />TEMPORARILY WITH TAPE <br />FOLD UP AND OUT OF WAY <br />SECURE FLAPS <br />STEP 2: <br />A. PRE-CUT GRACE VYCOR PLUS FLASHING FOR SILL, JAMB <br />AND HEAD FLASHINGS. SEE TABLE BELOW FOR FLASHING <br />LENGTH CUT LENGTHS. A 12" WIDE FLASHING IS <br />RECOMMENDED FOR 2X6 EXTERIOR WALLS SO THAT A FULL <br />DRAINAGE PLANE IS PROVIDED IN THE ROUGH OPENING. A <br />6" WIDE FLASHING IS RECOMMENDED FOR HEAD AND JAMB <br />FLASHINGS. <br />B. APPLY SILL FLASHING TO TOP WINDOW SILL. FLASHING <br />SHOULD EXTEND TO INSIDE EDGE OF SILL FRAMING TO <br />PROVIDE A FULL DRAINAGE PLANE FOR WINDOW OPENING. <br />FLASHING SHOULD EXTEND VERTICALLY UP THE JAMBS A <br />MINIMUM OF 6 ON BOTH SIDES. NOTE: SILL FLASHING <br />SHOULD NOT WRAP ONTO THE INSIDE OF THE WALL. <br />C. MAKE VERTICAL RELIEF CUTS STARTING FROM CORNER OF <br />WINDOW SILL UPWARDS. ROLL SILL FLASHING FIRMLY ONTO <br />EXTERIOR OF WALL. NOTE: SILL FLASHING SHOULD NOT <br />EXTEND PAST OUTSIDE EDGES OF JAMB FLASHING. <br />D. APPLY CORNER PATCH AT BASE OF RELIEF CUTS IN SILL <br />FLASHING. <br />EXTERIOR <br />SHEATHING <br />TURN UP 6" MIN. <br />12" SILL FLASHING WIDTH <br />RECOMMENDED <br />VYCOR PLUS APPLIE <br />HEAD NAIL FLANGE <br />6" HEAD FLASHING <br />HEAD FLASHING <br />EXTENDS BEYONI <br />JAMB FLASHING <br />LASHING <br />EDGE OF FRAMING <br />FOLD <br />1 TYPICAL WINDOW WATERPROOFING / FLASHING ASSEMBLY <br />SCALE. 1/2 = 1 -0 <br />STEP 3 <br />MFr.HAN1rAI <br />STEP 5 <br />STEP 6 <br />STEP 5: <br />A.
