Detail #: E-3.02AIntermediate Securement IntoStructural Substrate EPDM Systems

For metal stud mounted substrates other than plywood or OSB, see Detail E-3.02B.

Intermediate securement is required on all vertical fully adhered flashings in excess of 48" (1.2 m) o.c. 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.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 in order to mitigate the possibility of fastener back-out.Intermediate securement may be achieved in-seam with a GenFast 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 EPDM Cover Tape, and all TOP edges of EPDM Cover Tape must be caulked with EPDM Edge Caulk. GenFast Bar Anchor intermediate securement will be secured at 12" (304.8 mm) o.c. into the plywood or OSB substrate with #14 or #15 GenFast fasteners.

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 in 1/2" (12.7 mm) or greater thickness, 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 at most 48" (1.2 m) apart, secured through the sheathing to the metal studs with GenFast #14 Fasteners and GenFast Bar Anchor at 12" (304.8 mm) o.c. The intermediate securement Bar Anchors will extend from 4" (101.6 mm) minimum to 6" (152.4 mm) maximum from the finished roof surface and 4" (101.6 mm) minimum to 6" (152.4 mm) maximum from the metal coping or angle change at the top of the parapet. They must be stripped-in with EPDM Cover Tape, and all TOP edges of the EPDM Cover Tape must be caulked with EPDM Edge Caulk.Secure the metal strip to every metal stud with three GenFast #14 Fasteners with the strip centered at the point where you wishto mount the horizontally oriented intermediate membrane securement.

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 with Peel & Stick EPDM Flashing and spliced back together prior to filling the boot with GenFlex Pourable Sealer. Ensure the strip-in flashing extends a minimum of 3" (76.2 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 and also between penetrations and the sides of the pipe boot .

GenFlex Pourable Sealer

Cut the boot at the lowest ring. Clean the deck membrane, the boot flange and the inside of the pipe boot with GenFlex Cleaner, and allow to flash-off. For Peel & Stick EPDM Pipe Boots, use a GenFlex Scrub Pad & Handle to apply Primer to the deck membrane and to the inside of the boot and allow to flash off. Peel the release liner from the boot flange and mate to the prepared deck membrane. Roll with a 2" (50.8 mm) roller.For EPDM Pipe Boots (non Peel & Stick) apply GenSplice to the bottom of the boot flange and the deck membrane and allow to flash off before mating the flange to the prepared deck membrane.Fill the pipe boot with GenFlex Pourable Sealer, mounding the sealer to allow water to shed.

Remove existing flashing materials, rust, dirt, etc., from penetration prior to installing the GenPocket E.Seal around the penetration(s) prior to installation to prevent Pourable Sealer from entering roof systemUsing a GenFlex Scrub Pad & Handle, apply GenFlex Primer to penetrations and deck sheet where flange of GenPocket E will bond. Also apply primer to inside of the PVC ring (included with GenPocket E), and allow to flash off properly. Once the primer has flashed-off, place the PVC ring around the penetration. Be sure there is a 1" (25.4 mm) space between all penetrations and the PVC ring.Install penetration pocket over the PVC ring so that the ring fits completely inside the top overhang of the pocket.Center the pocket around the penetration, and locate the pre-cut area of the release paper on the underside of the pocket flange. Remove a small area of the paper closest to the PVC ring, and use hand pressure to mate inside edge of the flange to the deck membrane. This will help ensure the pocket does not shift while you remove the rest of the release paper. Pull the remainder of the release paper from the flange at a 45 degree angle, and mate the flange to the deck membrane. Roll flange from the inside to outside edge, using a rubber seam roller. Fill the pipe boot with GenFlex Pourable Sealer, mounding the sealer to allow water to shed. Extend the sealer to cover the top edges of the pocket walls.

If the GenPocket E 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 with Peel & Stick EPDM Flashing and spliced back together prior to being filled with GenFlex Pourable Sealer. Ensure the strip-in flashing extends a minimum of 3" (76.2 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 .

For scuppers flashed-in with GenFlex Peel & Stick EPDM Flashing or EPDM Cover Tape, first apply GenFlex Primer to bonding surface(s) with a GenFlex Scrub Pad & Handle. All transitions, T-joints, and overlaps must have an application of GenFlex Edge Caulk extending 3" (76.2 mm) from the transition, overlap, or T-joint in all directions.

Detail #: E-16.05 EPDM SystemsFlexGuard Peel & StickWalkway Pad Installation

Walkway pads are recommended at all permanent points of roof access and points on the roof requiring once-a-month or more service. Installation of walkway pads will reduce wear on the roofing membrane but will do little to mitigate the effects of "heavy" traffic, which can cause insulation damage if a suitable walk substrate is not designed to handle heavy traffic.


GenFlex Seam Tape

Remove the release paper from the seam tape, and mate the walkway pad to the prepared surface in a smooth motion, avoiding buckles in the walkway pad. Walk the walkway pad into place, or roll with a suitable roller.

NOTES:A On I-60 and I-75 systems, for all mechanically fastened insulations or thermal barriers, the number of fasteners per board should be

increased over the FMRC-approved field of roof spacing by:

50% In the roof perimeter

100% In the roof corners

Round up to the next whole number of fasteners.B For I-90 systems, refer to the Loss Prevention Data Sheet 1-29.

The width of the roof corners and perimeter is defined as the smaller of:

0.1 Times the building lesser plan dimension

0.4 Times the eave height

Subject to a minimum width of 4’ (1.2 m)

For GenFlex warranted projects on which no FM requirements apply, follow FM I-60 fastening patterns for buildings less than 50’ (15.2 m)high in non-hurricane zones. Please contact the GenFlex Technical Department for buildings over 50’ (15.2 m) high or located in hurricane or high wind zones.

On recover systems, Factory Mutual limits the insulation thickness to a maximum of one (1) inch (25.4 mm). Contact the GenFlex Technical Department for approvals over deck types other than metal or concrete, e.g. cementitious wood fiber, gypsum, etc. Minimum #14 Fasteners are required for concrete decks.
