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.

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.

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.

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.

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.

Higher Weather Performance Sill
- Cero's thermally broken Higher Weather Performance Sill offers 1/8" (3 mm) height adjustability to accommodate potential building movement. It seamlessly connects interior and exterior spaces, with an optional ADA-compliant track insert. The engineered drainage system ensures water management, and a French drain option is available for increased drainage needs.

Flush Sill for cero II
- This minimal design sits recessed at just 7/8" (23 mm) into the floor, allowing for discreet installation of finished flooring inserts. Ideal for commercial spaces like retail, hotels, and auto dealerships, it also complies with ADA standards. Note that the cero II Flush Sill is non-thermally broken.

Uncompromised Roller System
- These floor-supported panels employ carriers with encapsulated ball bearings, boasting a Gothic arch wheel bearing design that ensures a smoother glide with reduced friction. The stainless-steel wheels effortlessly slide along a stainless steel track, maintaining the sleek, minimalistic appearance by concealing each carrier within the bottom panel profile.
Perched above the Water Table
- NanaWall's Floor Supported Technology ensures rollers remain above the water table, ensuring long-term operational excellence. The cero system undergoes rigorous testing, withstanding 40,000 opening and closing cycles. Additionally, double-sided brushes in front of each roller prevent debris accumulation, ensuring continuous smooth operation.
