Name: Door Axis 68 Series Aluminum Bi-Fold Patio Door System, Insulated Glass
Brand: Door Axis
SKU: DA-DR-PAT-FOLD68-22-SB

The Door Axis 68 Series Aluminum Bi-Fold Patio Door System is a folding glass wall that opens a full patio span with insulated glass panels folding and stacking to the side. It serves homeowners, remodelers, and light commercial projects that want a wide, clean opening backed by contractor grade hardware and a quote reviewed fit.

The system is built on a 2.68 in (68 mm) aluminum frame with insulated double glazing and stainless folding hardware, including top and bottom pivots, intermediate carriers, and drop bolts. Panel runs of 2+2, 4+4, and 6+6 scale from single patio spans to full folding glass walls, and the two center leaves can swing independently as a daily pass door so the wall handles everyday traffic without folding the full run. Each system is fabricated to the opening size, finished in one of eight standard PVDF fluorocarbon or woodgrain film colors, and delivered as a complete frame, panel, and hardware kit ready for professional installation.

Installation Notes

Verify the structural header, opening squareness, and sill support before release; folding walls need a straight, level opening within fabrication tolerance.
Install a sill pan and integrate flashing and waterproofing with the wall assembly on exterior openings.
Set the frame plumb, level, and square, then hang and adjust panels so carriers and drop bolts engage smoothly.
Installation should be completed by a licensed contractor experienced with folding glass wall systems.
Final opening dimensions, stacking direction, and threshold condition are confirmed during quote review.

Warranty and Support

Warranty coverage is confirmed during quote review before release.
Quote packages include hardware adjustment guidance and finish care notes.

Frequently Asked Questions

How is the system sized to my opening?
Each system is fabricated to the opening. Share rough opening width and height during quote review and the panel run is engineered within the published panel width and height ranges.

Can I add an insect screen?
Folding runs do not carry an integrated screen. Exterior screening is quoted case by case, and the 126 Series sliding system is the integrated screen alternative in the same finish family.

Which finishes are available?
Eight standard finishes: Sand Black, Sand Gray, Snow Gray, Pure White, Fluorocarbon Champagne, Red Cherry, Golden Oak, and Black Walnut, applied as PVDF fluorocarbon or woodgrain film over extruded aluminum.

How does it perform in hot or cold weather?
Panels carry insulated double glazing with perimeter gaskets and interlock seals, and Low-E glass options are quoted on request. Project specific performance expectations are reviewed during quote review.
