1 WORK INCLUDED

(1) Supporting Deck Overlay
Recommended over steel decks, to provide continuous support for membrane control layers (this fulfills the requirement for continuity, British Columbia Building Code, Div. B, 5.4.1.2 (3)).
(2) Air or Vapour Controls
Self-adhering membrane (typical).
(3) Metal Support
For fully or intermittently unsupported side or end laps. Use pre-finished galvanized steel (min. 24 Ga.), fabricated at least 100 mm (4”) wider than membrane overlaps, and secured with compatible flat-head fasteners (two fasteners per flute, or as otherwise specified).
(4) Long edges (side laps)
Centre membrane runs along top flutes of steel deck (applicable when no deck overlay is specified and installed). Overlap membrane side laps at least 50 mm (2”), or as specified by the membrane manufacturer (whichever is greater). Side laps must be fully supported by the roof deck or a metal support.
(5) End laps
Overlap the roll ends at least 100 mm (4”), or as specified by the membrane manufacturer (whichever is greater). End laps must be fully supported by the roof deck or a metal support.
