Plan a large opening before selecting panels
Structure, drainage, floor transitions and stacking space are as important as the view.
At a glance
Water
Sill support, drainage and transitions must work as one assembly.
Operation
Panel count, weight, stacking and hardware shape daily use.
The useful decision
Structure, drainage, floor transitions and stacking space are as important as the view.
Define the experience
Decide whether the priority is daily access, the largest occasional opening, minimal frame lines or simple operation.
Coordinate early
Headers, substrate, sill support, water management and interior/exterior floor elevations affect feasibility.
Choose the configuration
Compare sliding, lift-and-slide and folding layouts, then confirm panel limits, handing, hardware and glass with the project team.
Bring this to the conversation
Project checklist
- Confirm rough-opening dimensions and structural design.
- Coordinate interior and exterior finished-floor elevations.
- Reserve clear space for moving or stacked panels.
- Plan delivery access and installation sequencing.
Avoid assumptions
Questions worth answering
- Is the largest opening needed daily or occasionally?
- Where will water drain at the sill?
- Can the site receive and handle the assembled components?
Before final selection
Explore large-opening doors
Confirm the exact product, current documentation, applicable codes and project conditions with the appropriate project professionals and Morrison team.
