Minimal Sliding Glass Walls

- NanaWall’s minimal framed sliding glass wall system is architectural minimalism at its finest
- With aluminum framed panels of a mere 1 5/16″ (34 mm) producing clean, uniform, and ultra-thin lines for maximum light-filled spaces
- Offering the largest panels available in the NanaWall product line, minimal sliding glass wall panels reach sizes as large as 9′ 10″ (W) x 14′ 9″ (H) (3000 mm x 4500 mm) for cero III

Creative Design Freedom
cero®―absolute architectural minimalism at its best―questions conventional boundaries. With cero, architectural design can be stripped down to its most essential elements allowing for light, form, material, space, and nature to speak for itself. Outside and inside become one.

ce•ro (ˈsirō)
noun
The minimal framed large panel sliding glass wall by NanaWall Systems. Simple in form yet engineered to perfection. Producing clean, uniform, and ultra-thin lines for maximum light filled spaces that connect the interior to the exterior.

A Floor to Ceiling Lens to the Outside
The award-winning cero offers full floor-to-ceiling sliding glass panels with recessed top and bottom tracks. Produced through time-tested premium German engineering, cero allows for maximum transparency with the largest panes of glass and the most minimal frames offered by NanaWall.

Narrow Stiles and Rails
With cero, the panel's rail and stiles are uniform with a consistent 1 5/16" (34 mm) top to bottom, achieving a symmetrical and minimal design.
Exterior
cero transforms glazed floor-to-ceiling façades into flexible openings in commercial settings such as auto dealerships, hotels, and restaurants.
Interior
For interiors, cero is a fully tested and sound rated minimal sliding glass wall capable of reaching sound control up STC 43.

NanaWall's intelligent approach and innovative use of materials reflects a creative integration of design and technology. Within each system component is the NanaWall DNA-components designed by NanaWall and crafted with exceptional quality that performs effortlessly while standing the test of time.

No Metal to Metal Contact
The system interlock design of 4 layers of soft gaskets allows for a soft closing of the panels. Transparent bumpers on the top and bottom vertical stile allow for a soft opening process.
Sophisticated Design Allows for Panel Deflection
cero's panel and interlock design is engineered to accommodate panel and glass deflection with a built-in tolerance of up to 1/4" (7 mm). This design also eliminates the concern of the metal vertical stiles touching the adjacent glass sliding panel during the opening and closing process.

With cero, security is provided with multipoint locking and a flat handle that is integrated into the 1 5/16" (34 mm) vertical profile stile to maintain the clean, minimal appearance. A full 1" (25 mm) throw securely locks the panel into a top and bottom adjustable locking receiver.
For those with higher security concerns, the system is able to meet the optional European security standards of either RC2 or RC3.

Uncompromised Roller System Equals Smooth Sliding
- cero II panels with double insulated glass have 2 carriers per panel and cero III panels with triple insulated glass have 4 carriers per panel.
- Floor supported cero panels are operated by carriers containing a pair of wheels with encapsulated and self-lubricating ball bearings.
- Unique to cero is a Gothic arch wheel bearing design. With a 2 point contact of each wheel to the bottom track, the system glides with less friction.
- cero's stainless steel wheels slide with ease on a stainless steel track.
- To maintain the sleek minimal look, each carrier is concealed within the bottom panel profile.
Elevated above Water Table
NanaWall Floor Supported Technology assures that the rollers run above the water table and the design allows for continued long term smooth operation.
cero has been tested to 40,000 opening and closing cycles.
Brushes for Continuous Smooth Operation
Double sided brushes, located in front of each roller, remove debris from the track to contribute to a smooth running system.

Higher Weather Performance Sill
To compensate for potential future building movement, cero's thermally broken Higher Weather Performance Sill offers height adjustability of up to 1/8" (3 mm).
cero's Higher Weather Performance Sill is fully recessed into the floor creating a clean uninterrupted transition from interior to exterior.
An optional track insert is available to meet ADA requirements.
Track drainage provided by an engineered, cascading water management system. For installations requiring even greater drainage due to exposure, a matching French drain system is available.
cero's Higher Weather Performance Sill is thermally broken.

Flush Sill for cero II
Aesthetically Disappearing Floor Track
The Flush Sill option for cero II is available for sheltered or interior environments creating aesthetically seamless transitions between spaces.
The minimal Flush Sill is fully recessed at a shallow 7/8" (23 mm) into the floor.
Finished flooring inserts can be easily installed in between the tracks making these sills virtually disappear. Sill design also makes for easy cleaning and maintenance.
For commercial environments, such as retail, hotels, and auto dealerships, the Flush Sill meets ADA requirements.
cero II's Flush Sill is non-thermally broken.

“We selected cero for its clean lines and simple, minimal frame around the glass, and because of the center-opening option with no need for a closet or pocket for the doors to nest,”
