The NanaWall Difference

NanaWall folding doors open to bring the outdoors in, and close to keep the outdoor elements out—not all glass wall manufacturers can confidently talk about performance when closed.

The care put into engineering NanaWall folding glass doors qualifies our systems for the most challenging architectural specifications. Certified independent testing confirms that a NanaWall folding door system meets or exceeds industry standards for air infiltration, water penetration, structural and thermal performance and forced entry. With a NanaWall folding glass doors exterior system, you can enjoy the best of both worlds: a room with a clear outdoor view and secure weather protection.

NanaWall folding glass doors create openings so wide you’ll forget you’re standing inside. Consecutive bi-folding panels connect to form a folding door system that can be hinged to one or both side jambs, and meet in a variety of configurations. When fully open, the panels stack 90 degrees to the opening, delivering unobstructed walkways and sightlines.


  • Swing door option: folding doors with an odd number of panels that stack to one side, a swing door is possible. For systems with an odd number of panels to both sides, a pair of swing doors is possible.
  • Versatile egress options: folding glass doors system can be opened fully or partially.
  • Easy maneuvering: one handed operation is possible for individuals of any size.
  • No extra track support necessary: our folding glass doors exterior system keeps all structural loads within the plane of the opening.
  • Support options: both top-hung and floor supported systems are available.
  • Multitude of stacking configurations: stack all panels on one side, or split the stacking. Inward or outward opening options are available.
