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 (see 8.1.2 Design).
- (5) Ventilation layer
- 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 (see 10.3.5.3 (1)(2)).
- (9) Ridge cap flashing
