SBS Details
1 WORK INCLUDED
- (1) Air/Vapour barrier
- Self-adhered membrane, as specified in design. Install following manufacturer’s requirements.
- (2) Roof system
- Conventionally insulated system shown (refer to the membrane Standard for requirements).
- (3) Field Membrane
- SBS-modified bituminous system shown (see Part 9 for standards)
- (4) Self-adhered membrane (pre-flashing)
- Apply over rough sill or sill woodwork. Prime as required.
- (5) Metal water-stop flashing
- Dimensions as specified in design. Mechanically attach to inside face of door sill. Cut flashing to fit opening width.
- (6) Membrane flashing
- Base membrane shown. Install to overlap and seal in metal water-stop flashing.
- (7) Membrane gussets
- Install in corners to seal joints.
- (8) Metal base flashing (under door)
- Optional; protection for membrane when pavers are installed (shown), or when exposed membrane is vulnerable to damage. Mechanical fasteners must be at least 87.5 mm (3-1/2”) above the drainage plane.
- (9) Membrane flashing
- Applicable for exterior-insulated walls. Seals roof membrane flashing to air/vapour barrier on wall and provides sufficient exposure for positive union with WRB (by others). Mechanically secure membrane (metal base flashing used for securement in this detail).
- (10) Metal base flashing (walls)
- Optional; protects membrane flashing from damage, and functions as removable panel to permit access to membrane flashing for future replacement.
- (11) Pavers and pedestals
- May be installed by others, if specified. See Part 14 for material and application requirements. Must be at least 12 mm (1/2”) away from other pavers, and from membrane flashing or metal base flashing, to permit adequate drainage.
