Floor Supported Technology
Versatile design for folding and sliding opening glass walls and doors.
- Flexible by design—works across folding, sliding operable glass walls where overhead support is limited.
- Engineered for smooth performance—floor-mounted design ensures long-term reliability and effortless operation.
- Ideal for remodels and complex projects—reduces the need for structural changes or reinforced headers.
What is a Floor Supported System?
Floor supported, also referred to as floor-mounted and bottom rolling, are systems that carry the weight of each operable glass panel on the floor track instead of the overhead structure or beam. The upper track is merely a guide. This design reduces the need for heavy structural reinforcement above the opening and is ideal for remodels, retrofits, and large openings where header support is limited.
NanaWall floor supported systems use stainless steel wheels on a stainless steel track to provide smooth and quiet operation, even when slight debris appears in the track. This precision-engineered design allows for adjustability, consistent alignment, and long-term reliability across both folding and sliding systems.
By transferring the load to the floor, these systems simplify design planning, preserve existing structure during remodeling, and maintain the same weather protection, durability, and energy efficiency as top-hung designs.
NanaWall floor supported technology combines precision engineering with architectural flexibility across both folding and sliding glass wall designs. By transferring the panel weight to the floor, these systems reduce overhead structural demands, simplify design, improve long-term performance, provide frictionless operation, and offer greater design freedom for virtually any project.
Engineered Stability
Transfers the panel load to the floor track instead of the overhead beam, reducing structural requirements and simplifying design for remodels and new builds.
Durability and Smooth Operation
Precision stainless steel rollers glide along a stainless steel track, maintaining frictionless, reliable movement even if debris should appear on the track. Rollers operate above the water table.
Design Versatility
Adaptable for remodels, retrofits, and large openings while offering the same long-term performance and weather protection as top-hung systems.

“Using the floor supported doors allowed us to have a very thin structure and allow the the indoor outdoor connection to be paramount and not have heavy beams in the way.”
— Jonathan Feldman, AIA, Feldman Architecture
“The multiple NanaWall systems installed throughout the lobby and restaurant offer exceptional flexibility. Guests can truly appreciate the ease of operation—even when opening panels that reach twelve feet in height. The NanaWall system seamlessly connects the indoors and outdoors, blending them into a single, connected space.”
— Andaz Hotel, Hawaii
“We get monsoons in Arizona that can flood our entire backyard and overflow the pool. That’s why we chose a floor supported folding glass system. I knew that opting for a floor supported design would ensure lasting performance.”
— Brian and Lori Lange, Homeowners

Frequently Asked Questions
Floor supported systems are ideal when overhead support is limited. They transfer panel weight to the floor, eliminating the need for reinforced headers. Both configurations offer the same weather protection, durability, and long-term performance.
Yes. Floor supported systems are often chosen for remodels because they potentially allow you to keep the existing header and avoid costly structural modifications. This makes them a practical and cost-effective choice without compromising performance or aesthetics.
Each system uses precision-engineered stainless steel rollers that glide on a stainless steel track, ensuring quiet, consistent movement. The design compensates for slight debris or uneven surfaces and is life-cycle tested through thousands of open and close operations for proven reliability.
NanaWall floor supported systems are engineered to perform even with up to ⅜ inch of debris in the track. Routine cleaning helps maintain smooth operation, but the durable stainless steel components resist corrosion and are designed for longevity in real-world conditions.
These systems are ideal for remodels, retrofits, and spaces with limited overhead structure. They are also a great fit for residential and commercial projects that require wide openings or designs that integrate indoor and outdoor environments without major structural changes.
Yes. NanaWall floor supported glass wall systems undergo the same rigorous performance and durability testing as top-hung designs. For example, models like the SL60 and NW Clad 740 have been tested to exceed 20,000 opening and closing cycles, ensuring long-term reliability.
