BEST PRACTICES
Hems
- Standard 1/2″ hems are recommended and included on this product for safety and added rigidity
- Hems fold to the underside and can affect fit on tight dimensions—plan accordingly
Measuring
- Measure finished wall/parapet width for top dimension (C), not framing alone
- Measure both legs (B & D) separately—do not assume they are equal
- Include all material build-up (roofing, insulation, coping substrate, etc.)
- Take measurements at multiple points to catch any wall or substrate variation
General
- Plan splice/joint locations for longer runs and allow for movement
