ce•ro (ˈsirō)
noun
The minimal framed large panel sliding glass wall by NanaWall—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 finest―questions conventional boundaries. With cero, architectural design is distilled to its most essential elements allowing for light, form, material, space, and nature to speak for itself. Outside and inside become one.
With cero, the panel’s rails and stiles are uniform with a consistent 1 5/16″ (34 mm) top to bottom, side to side, achieving a symmetrical and minimalist design. The result is beautiful sightlines and a 98% glass-to-frame ratio.
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—meticulously designed and engineered to offer unparalleled quality and durability ensuring systems stand the test of time.
NanaWall Floor Supported Technology assures that the rollers run above the water table, ensuring long-term operational excellence. cero has been rigorous testing to withstand 40,000 opening and closing cycles. Double-sided brushes in front of each roller prevent debris accumulation and contribute to continuous smooth operation.
Secure multipoint locking and flat handle are integrated into the 1 5/16" (34 mm) vertical profile to maintain the clean, minimal appearance. A full 1" (25 mm) throw securely locks the panel top and bottom. For higher security concerns, optional European security standards of either RC2 or RC3 are available.

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 acoustically rated minimal sliding glass wall capable of reaching sound control up a unit STC 43.
Uncompromised Roller System
Unique to cero is a Gothic arch wheel bearing design. With a 2-point contact of each stainless steel wheel to the bottom stainless steel track, the system glides with less friction. Floor supported cero panels are operated by concealed carriers containing a pair of wheels with encapsulated and self-lubricating ball bearings for smooth sliding.
Minimal Sill for cero II
For cero II, the Minimal Sill offers a minimalistic and aesthetic transition between the interior and exterior. Finished flooring inserts can be easily installed in between the tracks making this sill virtually disappear. The Minimal Sill is shallow, provides water management, and is barefoot friendly.
