- Documentation requirements
- Permit coordination, design information, installation records, labels, component schedules, photographs, and closeout details can add project administration to the physical work.
- Section construction
- Single-skin, insulated, and composite-core sections differ in weight and structure. The chosen profile and thickness affect the door package and counterbalance requirements.
- Supporting wall material
- Wood framing, masonry, concrete, and steel call for different anchors, tools, embedment details, edge clearances, and installation methods at the jambs.
