1 WORK INCLUDED

(1) Air/Vapour Control Layers
As specified by the Design Authority and installed to provide continuity for optimal control.
(2) Insulation
Installed in keeping with Section 7.3. Multiple layering illustrated; layers must be offset and staggered at least 304.8 mm (12”) in each direction.
(3) Insulation Overlay Panel
Required for fully adhered membrane systems or when overburden is specified. Panels must be offset and staggered from underlying insulation panels.
(4) Field Membrane
See Table 9.2. for permissible application methods and corresponding membrane properties. Membrane must be installed according to the requirements in Section 9.3.
(5) Edge Securement
Proprietary to the membrane manufacturer. Edge securement is required, irrespective of how the membrane is applied (i.e., adhered, self-adhered, mechanically fastened).
(6) Mechanical Fastening
Edge securement must be anchored to the roof structure to prevent membrane movement.
(7) Primer or Adhesive
Proprietary to the membrane manufacturer. Primer may be required for self-adhered membranes; adhesive is required for all other applications. All membranes applied to the vertical substrate must be fully adhered.
(8) Membrane Flashing
May be run continuously up the vertical substrate from the field or installed as separate flashing (see membrane manufacturer requirements). Membrane shall be carried up the vertical substrate at least 203.2 mm (8”) above the finished roof system surface, plus at least 76.2 mm (3”) for wall control layer overlap. In regions where heavy snow accumulation is possible, or to accommodate future roof membrane replacement, membrane should be carried at least 304.8 mm (12”) up the vertical substrate.
(9) Membrane Edge Securement and Sealant
All membranes applied to a vertical surface must be mechanically fastened. Fastener illustrated, together with sealant applied to upper membrane edge.

2 RELATED WORK BY OTHERS

(A) Acceptable Deck
Illustrated deck is representative. See Sub-section 2.1.5. for acceptable deck types and conditions.
(B) Wall Structure
Illustrated wall is representative. Wall control layers (i.e. water resistive barrier) must overlap roofing system to achieve continuity. See Sub-section 2.1.7. for wall conditions.
(C) Wall System Finish
Illustrated system is representative and shows water-resistive barrier overlapping roof membrane (See above, Item 8).

NOTE: See the EPDM Roof Systems Standard for additional requirements.
