“For this new project we wanted to expand the restaurant area so it would, in a sense, spill out into the park area. This makes it ideal for three-season dining. We looked at other wall systems, but felt ultimately that the NanaWall System was the best system for our application.”

- Aaron Arbuckle, Architectural Nexus

“We chose NanaWall because the large glass panels allow light into the room and the well-designed door system is easy for our staff to use daily to accommodate varying sized groups. The restaurant is more open and attractive contributing to increased guest occupancy.”

- Tamas Vago, Hyatt Regency

“We used NanaWall to create flexible space between three different skyboxes as we wanted to have three different spaces to rent. We've succeeded in creating a high-end experience the owner and end user have loved.”

- Christopher C. Colantino, TRM Architecture Design & Planning

"The durable metal clad exterior and high-quality hardware of the NanaWall system are able to stand up to our weather and everyday use of the door, while providing a seamless connection of space and expansive mountain views."

- Andrew Kosusko, Rice Fergus Miller Architecture & Planning

“With the curved 60’ wide NanaWall folding glass wall, it was possible to achieve a dramatic visual continuity while respecting the absolute privacy required by a law firm. The resulting flexibility of usage is invaluable.”

- Lisa Brundage, President, Archi-Techniques

“Our goal was to create the casual feeling of indoor/outdoor environment, with the flexibility of allowing the space to spill out to provide a colorful, inviting entry or to be closed off for private events.”

- Christen F. Soares, Field Paoli Architects

“Fantastic. Incredible. Best opening wall system I have ever seen. During the winter months there is not even a hint of cold air flow. The system opens and closes effortlessly.”
