Division D - Construction Details

ASM | Cylindrical Penetration (Flexible Boot Flashing) ( Article 12.3.2.1.)

Notice to Reader
Images used in a Construction Detail are representative and not prescriptive, and are not necessarily drawn to scale. They are intended to support the related Standard (Ref. Division A, Article 2.2.1.2.).

The reader may link to the related Article in the detail title, or link to the Standard as it relates to a specific element in the detail. All hyperlinks are displayed blue text.

ASM Details

ASM Cylindrical Penetration (Flexible Boot Flashing).png

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) Architectural Metal Roof Panel
Clips not illustrated.
(6) to (9) Pipe Boot
  • Set flashing diagonal to the direction of drainage, to direct water around the flashing.
  • Set in two continuous beads of acceptable sealant.
  • Secured with high-domed gasketed cladding-type screws.
  • Clamped to penetration with a stainless steel clamping ring (drawband).
  • Sealed between flashing and penetration.
(10) Water-tight storm collar
Installed by other trade (new construction only) or as required in this Standard. See 11.3.3 (5).

2 RELATED WORK BY OTHERS

(A) Pipe penetration
