FourFold and SixFold Panel Sets move and stack to an opening’s left, right, or center—adding more convenience for operators, and enabling widths beyond those of other bi-fold doors. Simultaneously, Floor Supported Technology reduces the need to modify headers on top.

See It in Action

In Kirkland, WA, the newly built Mesnick residence showcases the Generation 4 NW Aluminum 640 folding glass wall, which seamlessly connects the living room to the outdoor patio. Selected for its ease of use, accessible swing door, and industry's slimmest aluminum frame, this system maximizes natural light and energy efficiency. Its thermally broken design and floor supported panels transform this homeowner’s space into an open, airy environment.

“My NanaWall was my top wish list item for this house. I love the seamless indoor/outdoor entertaining it enables! Generation 4's slimmer profile offers more window view and is easy to open. It floods our space with natural light and extends our living area to the patio. NanaWall, the originator, has perfected bifold doors; no one does it better.” — Molly Mesnick, Mesnick Homes
