1 WORK INCLUDED

(1) Air or Vapour Control Layer: Installed following the requirements of Part 6 in this Standard. Tie in the control layers with membranes installed by other trades, to preserve continuity of the building enclosure (1a).
(2) Insulation: Installed in staggered and offset layers (not illustrated), and secured in accordance with the design of the system, which is based on the British Columbia Building Code, Part 4 and Part 5, and on Part 3 of the RoofStar Guarantee Standards for the membrane system type.
(3) Insulation Overlay: Subject to the requirements of Part 8 in the RoofStar Guarantee Standards for the membrane system type.
(4) Base Membrane (field): Mechanically attached, torch-applied, adhered or self-adhered. See Tables 9.1 and 9.2 for acceptable membrane types and securement options. See 9.3 for application requirements.
(5) Base Membrane (flashing): Carried vertically up a wall or parapet at least 200 mm (8”), and onto the roof field at least 100 mm (4”) (greater if required by the membrane manufacturer). Prime substrate, as required by the membrane manufacturer.
(6) Cap Membrane (field): Granule-surfaced membrane. See Tables 9.1 and 9.2 for acceptable cap membrane types and their securement options. See 9.3 for application requirements.
(7) Cap Membrane (flashing): Extended vertically past the termination of the base membrane flashing, to provide a positive seal at the top edge.
(8) Metal Cant Flashing: Secure metal flashings with appropriate fasteners set at least 87 mm (3 ½”) above the finished roof surface. Alternatively, secure flashing from the outside face (illustrated). See 13.3.7 Cant Edges for metal flashing securement requirements.
