RECOMMENDED INSTALLATION PROCEDURE LEVEL 3

Transcription

1 Step 1. Install Sill Flashing at Recessed Opening Product: 1.A Flashing Length = (Recessed Opening Width) + 12" 1.B Adhere sill flashing flush with the sill of the recessed opening. Each end of the sill flashing should extend 6" beyond the jambs of the recessed opening. 1.C Using a J-Roller, apply pressure while rolling entire surface of flashing to ensure adequate adhesion. Step 2. Sealant Application Prior to Installation of Recess Quick Corners Product: 2.A Apply a 3/8" continuous bead of sealant at the recessed sill/buck joint and recessed jamb/buck joint. Sealant should be applied 2 ½" across the recessed sill and up the recess jamb 2 ½". 2.B Apply a 3/8" continuous bead of sealant at the recessed sill/recessed jamb joint. The sealant applied at the recessed sill/recessed jamb joint should extend from the face of the bucks onto the exterior face of the sill flashing at the outside wall a minimum of 1". pg 1 of 7

2 Step 3. Install Recess Quick Corners at Recessed Sill Corners Product: RainBuster # , # , or # Recess Quick Corners 3.A Recess Depth: 2"= # , 2 ½"= # , 3"-3 ½"= # (Modified) See section details below. 3.B Apply a continuous 3/8" bead of sealant (L-shaped) to the backside of the outside wall leg of the Recess Quick Corner ensuring a continuous seal between the Recess Quick Corner and the flashing/framing. 3.C Position Recess Quick Corners firmly into buck/recessed sill/recessed jamb/ outside wall corners. 3.D Install Recess Quick Corner using nails or staples ensuring secure attachment through vertical legs only. Note: For 3"-3 ½" recess depths modify the # by cutting along the middepth cut line separating the outside corner portion from the inside corner portion. The outside corner portion should be installed prior to the inside corner portion. The inside corner portion should lap over the outside corner portion in a weather board (shingled) fashion x 6 wall with 2 x 4 bucks, 1 1 /2" reveal with 3" reveal option Vertical Section Elevation 2 x 6 wall with 2 x 4 bucks & 7 /16"- 1 /2" sheathing, 1 1 /2" reveal with 3 reveal option 3"-3 1 /2" sheathed recess ( 7 /16"- 1 /2" sheathing), 1 1 /2" reveal with 3" reveal option Vertical Section Elevation Vertical Section Elevation pg 2 of 7

3 Step 4. Install Flashing at Recessed Sill Corners Product: 12" RainBuster #415 Self-Adhered Flashing Membrane-40mil 4.A Flashing Length = (Recessed Opening Depth) + 4" 4.B Adhere flashing across recessed sill, over Recess Quick Corners, and up recessed jamb maintaining 3" of adhesion to recessed sill and jamb. Press flashing firmly into inside corner eliminating any voids or wrinkles between the flashing and Recess Quick Corners. 4.C Make relief cut at corner allowing flashing to fold and adhere over outside wall sill and jamb. 4.D Using a J-Roller, apply pressure while rolling entire surface of flashing to ensure adequate adhesion. Step 5. Install Flashing on Recessed Sill Product: 12" RainBuster #415 Self-Adhered Flashing Membrane-40mil 5.A Flashing Length = (Recessed Opening Width) 5.B Adhere flashing flush to the sill of the window rough opening, down wood blocking, across recessed sill, and over sill flashing (minimum 4" lap). Press flashing firmly into wood blocking/recessed sill corner eliminating any voids or wrinkles. 5.C Using a J-Roller, apply pressure while rolling entire surface of flashing to ensure adequate adhesion. pg 3 of 7

4 Step 6. Install Jamb Flashing Product: 6.A Flashing Length = (Recessed Opening Height) + 14" 6.B Position jamb flashing into recessed opening. Make 2" vertical relief cut at top of jamb flashing to allow flashing to fold onto bottom of header at wood blocking/recessed header/jamb corner. 6.C Adhere jamb flashing flush with the jamb of the window rough opening, over the wood blocking, onto the recessed header, across the recessed jamb, and onto the outside wall. Press jamb flashing firmly into corners eliminating any voids or wrinkles. Jamb flashing should extend 2" onto the recessed header and to within 1/2" or flush with the bottom edge of the sill flashing. 6.D Using a J-Roller, apply pressure while rolling entire surface of flashing to ensure adequate adhesion. pg 4 of 7

5 Step 7. Install Integral Flanged Window Product: 7.A Apply a 3/8" continuous bead of sealant to the backside of the entire window flange. Apply sealant in line with the prepunched holes in the window flange. 7.B Sealant must be applied no longer than 20 minutes prior to installation of window. 7.C Install window per window manufacturer s installation specifications ensuring window is securely fastened and plumb, level, and square. 7.D Sealant squeeze out should be visible around perimeter and through all prepunched holes in the window flange. Tool (knockdown) sealant squeeze out flat. Step 8. Install Jamb Flashing-Double Wrap/Counter Flashing Product: 8.A Flashing Length = Recessed Opening Height 8.B Adhere jamb flashing flush with edge of window, over the window flange and existing jamb flashing. Jamb flashing should extend from top to bottom of recessed opening. pg 5 of 7

6 Step 9. Install Head Flashing Product: 9.A Flashing Length = (Rough Opening Width) + (Width of Jamb Flashings) + 2" 9.B Install head flashing over the window flange and flush with the top of the window at the top of recessed opening. Each end of the head flashing should extend the width of the jamb flashing + 1" on each side of the recessed opening. 9.C Position head flashing into recessed opening and temporarily secure along top edge. 9.D Make vertical relief cuts at recessed jambs for head flashing to fold into recessed opening. 9.E Adhere flashing over window flange flush with the top of the window. Continue adhering flashing up the wood blocking, across the recessed header and up the outside wall (minimum 4"). Press flashing firmly into wood blocking/recessed header corner eliminating any voids or wrinkles. 9.F Using a J-Roller, apply pressure and roll entire surface of flashing. 9.G Fasten with staples or nails along top edge of flashing. Use minimum number of fasteners required to keep flashing in place. Step 10. Apply Cap Bead of Sealant at Recessed Corners Product: 10.A Apply a 1/2"-5/8" cap bead of sealant at the recessed header/jamb and recessed sill/jamb corners. Using a putty knife, tool sealant into corners ensuring flashing seams are sealed. pg 6 of 7

7 In stucco applications, follow this additional step. If not, disregard. Step 11. Installation of Bond Breaker (by others) Product: Weather resistive barrier (building paper) by others (non-rainbuster product) 11.A After the weather resistive barrier has been properly integrated (weather board/ship lap fashion) with the window and door flashing systems, an additional piece of weather resistive barrier should be installed over the sill flashing acting as a bond breaker. 11.B Position weather resistive barrier onto reveal, recessed sill, and outside wall. Remove and cut to size. DO NOT CUT IN PLACE. Reposition and temporarily secure with minimum number of furring nails required to keep weather resistive barrier in place. Seal furring nails with RainBuster 900 Sealant/ Adhesive. Weather resistive barrier should be flush with bottom of window and flush with the recessed sill/jamb corners, continuing down the outside wall, covering the flashing completely. Installation Recommendations: It s recommended that backing (OSB, plywood, dimensional lumber) be installed to support flashing at all window and door openings. Installation substrates should be clean and free from substances and protrusions that could adversely effect adhesion and or compromise flashing/membrane performance. When an installation requires adhering RainBuster #415 Self-Adhered Flashing Membrane directly to the substrate (OSB, plywood, fiberglass faced gypsum board, masonry, and concrete) an adhesion test is recommended to ensure sufficient adhesion is achieved. Adhesion may be improved by rolling the membrane with a J-roller. In some cases priming the surface with an approved primer may be required to achieve sufficient adhesion. In 3-coat stucco applications, it s recommended that all flashing be covered by the Weather Resistive Barrier (WRB). After the WRB has been properly integrated (weather board/ship lap fashion) with the window and door flashing systems an additional piece of WRB should be installed over the sill flashing acting as a bond breaker. pg 7 of 7
