1 WORK INCLUDED

(1) Underlayment
The type of underlay required is determined by roof slope.
(2) Insulation
Offset and stagger layers 300 mm (12").
(3) Vapour-permeable separation membrane
Installed over insulation and required on all insulated Architectural Sheet Metal Roof Systems. The material must be located between the insulation and metal panels/ventilation material (see 8.1.2 Design).
(4) Ventilation beneath panels
A ventilation space is required on slopes less than 1:3; entangled mesh (shown) may be used as void fill. The ventilation space facilitates drying as condensation forms on the underside of the metal panels.
(5) Bearing plate
Only thermally non-conductive clips or bars passing through the insulation assembly, or mechanically fastened bearing plates, may be used to secure and support insulation panels, or provide support for panel clips.
(6) Architectural metal panel clip
(7) Architectural metal roof panel (lower)
Lower, installed prior to the pipe flashing, cut hole large enough to allow for movement. Extend 400 mm (16") upslope beyond the pipe.
(8) Spaced Cleat
Cleats, set in accepted caulking, spaced 50 mm (2") and fastened with compatible non-corrosive flat head screws.
(9) Sealant
(10) Split panel
(11) Backpan Flashing
Required for curbs up to 900 mm (36") wide.
(12) Metal Curb Flashing
(13) Metal Counter Flashing
(14) Architectural metal roof panel (upper)
Installed after penetration flashing. Cut hole for pipe penetration and turn lower panel end under to hook onto cleat.
