FABRICATION

Folding Glass Wall: Use solid, quad-layer, cross-grained wood for panels, connected to hinges, sliding, and folding hardware, locking hardware and handles, threshold and track, glass and glazing, and sound gasketing.

• Each unit factory pre-assembled and shipped with complete system components and installation instructions.
• Exposed work is to be carefully matched to produce continuity of line and design with all joints.
• No raw edges are visible at joints.
• Wood frame and panel components are to be sealed with a clear sand sealer or primer.

ACCESSORIES

Provide sidelights, transoms, corner posts, or single or double doors as indicated.

EXECUTION

EXAMINATION
Examination and Acceptance of Conditions per Section 01 70 00 and as follows:

1. Carefully examine rough openings with the Installer present, for compliance with requirements affecting Work performance.

   • Examine surfaces of openings and verify dimensions; verify rough openings are level, plumb, and square with no unevenness, bowing, or bumps on the floor; and other conditions as required by the manufacturer for readiness to receive Work.
   • Verify structural integrity of the header for deflection with live and dead loads limited to 1/4 inch (6 mm). Provide structural support for lateral loads, and both wind load and eccentric load when the panels are stacked open.
     NOTE: Before installing NanaWall, it is recommended that all building dead loads be applied to the header. Allow a reasonable amount of time for the dead load’s effect on the header; only then can the building’s live load be used to meet the above requirement of 1/4 inch (6 mm). If this is not done, both dead and live loads need to be considered.

2. Proceed with installation only after unsatisfactory conditions have been corrected.

INSTALLATION

General:
Install the Folding Glass Partition system by the Drawings, approved submittals, manufacturer’s recommendations, and installation instructions, and as follows:

1. Properly seal around the opening perimeter to reduce sound infiltration from surroundings.
2. Securely attach anchorage devices to rigidly fit the frame in place, level, straight, plumb, and square. Install the frame in proper elevation, plane, and location, and proper alignment with other work.
3. Wood Finishing: Field finish wood under Section 09 90 00, Painting and Coating; seal and finish promptly after installation and before exposure.
4. Install panels, handles, locksets, gasketing, and other accessories according to the manufacturer’s recommendations and instructions.

FIELD QUALITY CONTROL

• Field Tests and Inspections per Section 01 40 00 of the following:
  1. Verify the Folding Glass Partition system operates and functions properly. Adjust hardware for proper operation.
• Non-Conforming Work: Repair or replace non-conforming work as directed by the Architect; see General and Supplementary Conditions, and Division 01, General Requirements.

CLEANING AND PROTECTION

• Keep units closed and protect the Folding Glass Partition installation against damage from construction activities.
• Remove protective coatings and use manufacturer-recommended methods to clean exposed surfaces.
