NOTE: For the highest levels of insulation and energy efficiency, cero's profiles are thermally broken
with glass fiber reinforced polyamide with thermal breaks aligned in the same plane.

Thermal performance values vary depending on the glass, system, and configuration used in each individual application. U-Values as low as 0.29 and SHGC values as low as 0.19 are available to meet energy code requirements.

Condensation may occur when system is installed in cold climates or in a facility with high indoor humidity. If condensation could be an issue for your application, NanaWall recommends taking appropriate measures during the design and construction phase to reduce or eliminate the possibility of condensation. There are many third-party sources discussing the nature of condensation and ways to reduce or eliminate condensation, including publications by AAMA, WDMA, and Efficient Windows Collaborative.

2.03 MATERIALS
NOTE: A system interlock design with numerous layers of double fin weather seals and soft bubble gaskets allows for soft opening and closing with no metal-to-metal contact. The transparent bumpers on the top and bottom vertical stile facilitates a soft opening process.
This sophisticated design also allows for panel deflection. cero's panel and interlock design
are engineered to accommodate panel and glass deflection with a built-in tolerance of up to 1/4 inch (6 mm). It also minimizes the concern of vertical metal stiles touching adjacent sliding panel glass during the opening and closing process.

A. Sliding Glass Wall Description: Sliding and fixed, large-area glass panels in an extruded thermally broken aluminum frame. Panels slide on multiple stainless-steel carrier rollers with double-row deep groove ball-bearings and rolls on single or tandem stainless-steel rail runner inserts in floor track. Flat 2-point locking handle, gasket seals and brushes, a hidden integrated drainage offset duct system, and glazing rebate ventilation for controlled back-ventilation of the panel edge. Frame is thermally isolated with glass-fiber reinforced polyamide cross-pieces.

Linear panel system load transfer to structure at floor.
NOTE: cero II Double-Glazed: Maximum panel Widths up to 7' 4-1/2" (2250 mm) and Heights up to
13' 1" (4000 mm). Maximum panel Widths of 7' 1" (2150 mm) and Height up to 14' (4250 mm).
cero III Triple-Glazed: Maximum panel Widths up to 9' 10" (3000 mm) and Heights up to
15' (4550 mm).
Contact NanaWall for sizing questions. Please note that additional freight charges may apply for larger panel sizes.

b. Pin locks not acceptable. NOTE: For projects requiring outside locking and connecting to electronic security systems, an
electromagnetic lock or maglock option by others.
For those with higher security concerns, cero® can meet the optional European security
standards of either RC2 or RC3. European standards are more stringent than that of US forced entry testing. The burglary resistance quality of a window/sliding door unit is largely determined by the interaction of frame profiles, glazing, and hardware. With the 15-minute forced entry test for
RC2, a locked cero® passed security breach attempts using basic tools such as
screwdrivers, pliers, vise grips, and wedges on the system. RC3 is a 20 minute test in which
a crowbar is added to the basic tools in the attempt to open the closed and locked cero®
system. Retain Standard or Class RC2 for cero II Double-Glazed and Standard, Class RC2 or RC3 for cero III Triple-Glazed below.

3.01 EXAMINATION
A. Examination and Acceptance of Conditions per Section 01 70 00 and as follows:
Carefully examine rough openings with Installer present, for compliance with requirements affecting Work performance.
a. Verify that field measurements, substrates, tolerances, levelness, plumbness, cleanliness and other conditions are as required by the manufacturer, and ready to receive Work.
b. Verify block-out dimensions and structural support for flush recessed surrounding frame.
c. Verify the structural integrity of the header for deflection with live and dead loads limited to 1/4 inch (6 mm). Provide structural support on all four sides for lateral loads, and both wind load and eccentric load when the panels are stacked open.
NOTE: Structural support for lateral loads such as forced entry, etc. to be provided. It's recommended that all building dead loads be applied to the header prior to installing the unit. 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 live load be used to meet the above requirement of 1/4 inch (6 mm). If not, both dead and live loads need to be considered.
Proceed with installation only after unsatisfactory conditions have been corrected.
3.02 INSTALLATION
A. General: Install Sliding Glass Wall system in accordance with the Drawings, approved submittals, manufacturers' recommendations, and installation instructions, and as follows:
Properly seal around opening perimeter.
Securely attach anchorage devices to rigidly fit surrounding frame in place, level, straight, plumb and square. Install frame in proper elevation, plane, and location, and in proper alignment with other work. Integrate frames into walls, ceilings, and floors flush or as otherwise as indicated.
Lower track designed to drain; provide connections to allow for drainage.
Install glass panels, handles, lockset, and other accessories in accordance with manufacturer's recommendations and instructions.
Provide connections to alarm system, position monitoring and sensor notification systems.
