14 Exterior System by Architectural Design TPO Bonding Adhesive GenFast Bar Anchor See Notes #3 & #4 TPO Membrane 48" Max. (1.2 m) See Note #1 Plywood or OSB ONLY See Note #2 Alternate securement method. Masonry / Concrete TPO Cover Tape and Clear Primer or 6" (152.4 mm) wide TPO Reinforced Membrane See Note #3 Masonry / Concrete Refer to spacing dimensions shown above. Bar Anchor See Note #3 1. Intermediate securement is required on all vertical flashings in excess of 48" (1.2 m) for standard TPO membrane flashings (non Peel and Stick). For applications greater than 48" (1.2 m) but less than 8 ' (2.4 m), install the intermediate securement along a horizontal line halfway between the top of the wall or parapet and the finished roof surface. Repeat as necessary at 48" (1.2 m) intervals. Peel & Stick TPO membrane flashings may be applied over an approved, primed substrate without height limitation without additional membrane securement. 2. Plywood or OSB securement to metal studs must be in accordance with industry standards and capable of preventing the plywood or OSB from warping or bowing. Special care should be taken to ensure tight and flush joints in the sheathing material. Securement must be achieved with an appropriate screw-type fastener versus nails in order to mitigate the possibility of fastener back-out. 3. Intermediate securement may be achieved with an inner-seam Bar Anchor as shown or by the application of the Bar Anchor through the flashing membrane. If the Bar Anchor is secured through the flashing membrane, it must be stripped-in with TPO Reinforced membrane hot air welded to the flashing or TPO Cover Tape set in Clear Primer and caulked along the top edge. 4. Anchor Bar intermediate securement will be secured at o.c. (304.8 mm) into the approved substrate with the appropriate GenFast fasteners. For metal stud mounted substrates other than plywood or OSB, see Detail T Intermediate Securement Into Structural Substrate Detail #: T For most current information as well as promotional literature refer to:

( mm) Substrate Other Than Plywood or OSB See Note #1 Base Flashing Securement ALTERNATE METHOD: In situations where it is advantageous to mount the intermediate securement horizontally that involves a non-structural substrate a 22 ga (0.76 mm) metal securement strip may be secured through the non-structural substrate to the metal studs before the flashing is applied to serve as a point of anchorage for the intermediate membrane securement. 22 ga steel (0.76 mm) - 6" wide (152.4 mm) Metal stud mounted sheathing applications using other than plywood or OSB that are acceptable to bond directly to membrane include: 1/2" (12.7 mm) or greater DensDeck Standard or DensDeck Prime (NOT DensGlass Gold), exterior exposure faced gypsum board at least 1/2" (12.7 mm) thick, etc. Metal stud mounted parapet and wall sheathing other than plywood or OSB exceeding 48" (1.2 m) in height require vertically mounted intermediate securement spaced a maximum of 48" (1.2 m) apart and secured through the sheathing into the metal studs with #14 fasteners and Bar Anchor at o.c. (304.8 mm). The intermediate securement Bar Anchors will extend from a minimum of 4" (101.6 mm) to a maximum of 6" (152.4 mm) from the finished roof surface and a minimum of 4" (101.6 mm) to a maximum of 6" (152.4 mm) from the metal coping or angle change at the top of the parapet. They must be stripped-in with TPO reinforced flashing hot air welded in place or TPO Cover Tape set in Clear Primer with the upper edge caulked. Secure the metal strip to every metal stud with three GenFast #14 Fasteners with the strip centered at the point where you wish to mount the horizontally oriented intermediate membrane securement.

30 Clear Primer See step #4 Pourable Sealer TPO Membrane Cut Along Lowest Ring In order to use a TPO Pipe Boot as a pourable sealer pocket follow these steps: 1. Cut the boot at the lowest ring. 2. Clean the deck membrane, the boot flange and the inside of the pipe boot with Cleaner, and allow to flash-off. 3. Once the Cleaner has flashed-off, hot air weld the boot flange to the deck membrane centered on the penetration(s). 4. Apply Clear Primer to the inside of the boot and allow to flash off. 5. Fill the pipe boot with Pourable Sealer mounding the sealer to allow water to shed. Extend the sealer to cover the top edges of the boot walls. If the boot cannot be installed over the top of a penetration, the boot may be cut in order to place the boot around the object being sealed. If a cut is required, it must be overlaid and welded back together with TPO Non-Reinforced Flashing prior to the boot being filled with Pourable Sealer. Ensure the strip-in flashing extends a minimum of 1 1/2" (38.1 mm) beyond the step-off of the flange to ensure an adequate seal. NOTE: In order to achieve an adequate seal, there must be 1" (25.4 mm) of space between penetrations as well as between penetrations and the sides of the pipe boot. When using a TPO Pipe Boot as a pourable sealer pocket, removing the taper from the upper edge of the rim makes it easier to install the clamp because it will not slide up off of the boot. Flare the upper edge of the boot to remove the taper in the molded boot before installing it. Use adequate heat from a heat gun to soften the TPO material before attempting to flare it.

Strip in pocket flange with TPO Non-Reinforced Flashing welded to the flange and to deck membrane TPO Molded Corners Apply TPO molded corners to the pocket. (Required because of the need to fill out flange radius corners with a separate piece of coated metal) TPO Edge Caulk Apply TPO Caulk to the flashing edge that rests next to the metal pan all the way around the detail to keep water from sitting in the void. 5. Pourable Sealer Grout Filler (if applicable) Penetrations must be positioned a minimum of 1" apart and also 1" from the pocket sides. Pourable Sealer must be a minimum of 2" deep - non-shrinking grout filler may be used to fill a pocket to a point 2" from top if the pocket exceeds 2" in depth.

32 Clear Primer See step #7 Pourable Sealer TPO Membrane GenPocket T PVC Ring (Included with GenPocket T) 1. Remove existing flashing materials, rust, dirt, etc., from penetration prior to installing the GenPocket T. 2. Seal around the penetration(s) prior to installation to prevent Pourable Sealer from entering roof system 3. Clean the deck membrane Cleaner, and allow to flash-off. 4. Once the Cleaner has flashed-off, place the PVC ring (included with GenPocket T) around the penetration. 5. Install penetration pocket over the PVC ring so that the ring fits completely inside the top overhang of the pocket. 6. Center the pocket around the penetration, and weld the flange to the deck membrane. 7. After welds have cooled, apply Clear Primer to all areas of the penetration(s) and all surfaces that the Pourable Sealer will contact within the cavity. Prime the top of the pocket. Allow to flash-off. 8. Fill the pipe boot with Pourable Sealer, mounding the sealer to allow water to shed. Extend the sealer to cover the top edges of the pocket walls. 5. If the GenPocket T cannot be installed over the top of a penetration, the pocket may be cut in order to place it around the penetration. If a cut is required, it must be overlaid and welded back together with TPO Non-Reinforced Flashing prior to being filled with Pourable Sealer. Ensure the strip-in flashing extends a minimum of 1 1/2" (38.1 mm) beyond the step-off of the flange to ensure an adequate seal. NOTE: In order to achieve an adequate seal, there must be 1" (25.4 mm) of space between penetrations as well as between penetrations and the sides of the pipe boot.
