Design
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.
Symmetrical Picture Frame Effect
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.
Minimalist Beauty-Maximal Benefit
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 perform effortlessly while standing the test of time.
Operation
Uncompromised Roller System equals smooth sliding
Engineered Features of the Roller System:
- 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.
Soft Opening and Closing
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.
HIGHLY SECURE LOCKING
Multipoint Tamper-Resistant System
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.

Installation
Certified Installers
All opening requirements and surrounding conditions must be ready and meet the NanaWall supplied drawings before the certified installer arrives. Installers can review the openings before installation to ensure accuracy and verify all opening requirements have been met. Upon completion, the certified installer will ask to have a sign-off sheet completed, this will ensure your satisfaction with the installation of your NanaWall system. The certified installer will be available for a complete operational demonstration at time of installation.
NanaWall helps certified installers through continuous education to make sure they are up to date on all of our 20+ different systems. Their training process includes extensive education for both folding and sliding systems. Our installation management team makes periodic site visits to ensure the high standard of quality installation is maintained. Due to the extensive training your certified installer receives, it will ensure your NanaWall System is installed right, on-time, and hassle-free.
A benefit using certified installers is increased warranty coverage (review for details) of your new NanaWall system. Many areas have both commercial and residential trained installers.
Preventative Maintenance and Repair Services Available
Certified installers are available for servicing, repairs, and routine maintenance of your system.
Please contact your local NanaWall Sales Representative to arrange certified installation services for your project.
Installation Considerations
The approximate weight of a panel is the following:
Tempered Single Glazing: 4 - 4.5* lbs/sqft
Insulated Tempered Glazing: 5.5 - 8* lbs/sqft
Tempered Triple Glazing: 6 - 8.5* lbs/sqft
* The higher values applies to taller units
Single Impact Glazing: 8 lbs/sqft
Insulated Impact Glazing: 11 lbs/sqft
For the HSW75, FSW75, CSW75, PrivaSEE, and ClimaCLEAR systems the weight of a panel with 1/2" glass is 8 lbs/sqft.
For cero II the approximate weight of a panel for double glazed is 10 lbs/sqft and for double glazed laminated is 12 lbs/sqft.
For cero III the approximate weight of a panel for triple glazed is 13 lbs/sqft and for triple glazed laminated is 15 lbs/sqft.
The vertical structural deflection of the header should be the lesser of L/720 of the span and 1/4" under full loads. Structural support for lateral loads (both windload and when the panels are stacked open) must also be provided.
For floor supported systems (SL70, SL73, SL82, SL60u, WA67u and WD66u, please note that there is no vertical load on the header).
It is recommended that all building loads be applied to the header prior to installing the NanaWall. If so and if a reasonable amount of time has been allowed for the effect of this dead load on the header, only then can the building's live can be used to meet the above requirements of L/720 or 1/4". If not, both the dead and live loads needs to be considered.
