Glass Walls Windows

Folding Windows

Horizontal accordion-style windows with flexible sizing

  • Accommodate small openings or large walls of windows
  • Available in aluminum, wood, and aluminum clad frames
  • Superior weather performance and energy efficiency

Operable Accordion Window Systems

NanaWall folding windows offer the same design principles as folding glass walls with narrow frames, high performance, and easy operation.

Versatile Styling and Finishes

Customize your folding windows with aluminum, wood, or aluminum clad frames. Choose from diverse colors, finishes, and simulated divided lites to personalize or match existing aesthetics.

Exceptional Weather Performance

Designed with long-lasting durability, NanaWall accordion-style windows offer advanced weather protection and energy efficiency, ensuring year-round comfort in any climate.

Smooth Operation and Durability

Alongside smooth, single-handed operation, our folding windows meet or exceed industry standards for air infiltration, water penetration, structural performance, and forced entry.

Unlike traditional sliding windows, accordion-style systems make full use of the opening rather than restricting the space to only half of the opening.

Standard to our folding windows is a two-point locking mechanism consisting of a top and bottom locking rod for added security and peace of mind.

We engineer independently-tested hurricane impact systems for air infiltration, water penetration, and structural load with excellent results. Our Miami-Dade approved SL73 is the impact-rated solution for high-velocity hurricane zones.

Matching Window Door Combo

Achieve unparalleled flexibility with a customizable window door combination. Folding windows can be paired with full-height folding glass doors with matching frame styles for cohesive design and optimal functionality.

Maximize counter space with a functional pass-through window ideal for entertaining and al fresco dining, and to capitalize on the indoor/outdoor experience.
