PART 2 - PRODUCTS
2.01 MATERIALS
A. Project design is based on materials and systems of Ceilings Plus, Los Angeles, CA 800-822-3411, www.ceilingsplus.com.
Other manufacturers must be approved prior to the bid in written form, by the architect. Specified manufacturer's standard of quality and manufacturing tolerances shall be criteria for evaluating "equivalent" product.
2.02 MODULAR WOOD WALL PANELS
A. Modular Wood Panels, "Wall Forms" by Ceilings Plus with “Arboreal” Wood Veneer Finish
1. Panel Construction: The wall panels are to be die formed from a single sheet of primed aluminum and 1/32” thick wood veneer face. The panels to be formed with a minimum 1-1/2" integral return edge on all panel sides. No indentations, marks or defacing of the exposed surface of the wood wall panel will be allowed. The primed porous aluminum panels shall be formed in adequate thickness and factory formed to specified dimensions.
2. Adhesion: The adhesion shall be formaldehyde free with a cross linked emulsion . The primed aluminum properties shall included, high shear strength, with adhesion levels greater than 8lbs per square inch.
3. Veneer: All exposed surfaces of the veneer shall be finish sanded with 600-grit sandpaper between sealer and finish coat. The wood veneer specie shall be 3 face on (all exposed faces). Veneer shall be as selected by the architect. Range of veneer grain and color to be submitted for approval. The panels will be finished with a clear, two-step sealer and topcoat.
4. Perforations. (Optional) Perforations per architect selection. Panels to have a solid margin, non perforated, on all sides.
5. Sound absorbing material. (Optional) to be a gray, black or white, non-woven fabric with Class 1 fire rating. Perforated panels with absorbing material to achieve an N.R.C. of .70-.80 minimum.
B. No fasteners of any kind shall be visible on exposed face surfaces of wall panels or support brackets. Down light openings and sprinkler holes shall be factory precision cut as required.
C. Fire tests. Complete system test including mounting, primed aluminum and veneer with finish shall meet ASTM E84 Class I. Flame spread 20.
2.03 ATTACHMENT SYSTEM
A. Support system shall be designed to accommodate wall panels. Panels shall be removable without the use of special tools.
B. Construction:
1. Attachment system: Install primary channel runners to existing wall substrates using appropriate drywall or concrete anchor screws or bolts as recommended by the manufacturer. Shim and level runners as necessary prior to panel installation. Install runners in a continuous horizontal row, patterns as dictated by panel joint layout as reflected on the architectural plans and approved shop drawings. Attach insulation pad to metal pans prior to panel installation. Install metal panels by engaging onto channel supports and locking down in place. Panels and trim shall be installed plumb and true without distortion. Exposed fasteners of any kind will not be acceptable.
2. Horizontal seams allowed only where indicated on plans.
3. Positive alignment lips to be provided to maintain tight hairline joints.
4. Anchors and inserts: furnish anchoring devices as required for installation of column covers.
5. Factory fabricate and finish all components to the satisfaction of the architect. The installation system shall allow for removable components without the use of exposed fasteners, hardware or supports. All brackets and hardware shall be illustrated on shop drawings. Provide for ceiling reveal and cove base as shown on plans.
6. Joint reveals and alignments shall not exceed plus or minus 1/64".
PART 3 - EXECUTION
3.01 INSPECTION
A. General Installation:
1. Materials shall be installed in strict accordance with procedures recommended by the manufacturer and requirements of agencies having jurisdiction. All materials for this section shall be from a single source manufacturer with minimum 5 years experience with products of the nature specified.
2. Install work in strict accordance with manufacturer's recommendations and approved shop drawings. Neatly cut and reinforce openings in metal panels to allow for field conditions. Reinforce cuts to protect insulation and insure structural security and acoustical integrity of panels.
3.02 ALLOWABLE TOLERANCES
A. Maximum deviation from level and flat of the completed wall panels shall not exceed 1/16" in 10 ft. when measured with a straightedge placed at any location on the wall panel; 1/4" total deviation on any single wall elevation.
B. Finish panel surface true within L/360 of panel diagonal.
C. Install work consistent with specified quality grade plumb, level, true and straight with no distortions. Shim as required, using concealed slate, or other nonorganic shims.
