1 WORK INCLUDED

(1) Underlayment
The type of underlay required is determined by roof slope.
(2) Ridge girts
May be required by engineer for panel drag load fasteners. Secured using compatible non-corrosive fasteners.
(3) Insulation
Offset and stagger layers 300 mm (12").
(4) 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.
(5) 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.
(6) Architectural metal roof panel
Top end of panels must be "bread-panned". Clips are not illustrated.
(7) Drag-load fasteners
Compatible non-corrosive fasteners.
(8) Foam closures
may be used to close ridge when cap flashing is mechanically attached to the panels ribs.
(9) Ridge cap flashing
(10) Fasteners

2 RELATED WORK BY OTHERS

(A) Acceptable Deck
