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 LAMINATE WOOD CEILING PANELS
A. Modular Wood Panels, "Illusions" by Ceilings Plus with “Sarante’” Laminated Finish
1. Panel Construction: The ceiling panels are to be die formed from a single sheet of primed aluminum and laminate face. The panels to be formed with a minimum 1-1/4" integral return edge on all panel sides. No indentations, marks or defacing of the exposed surface of the laminated ceiling panel will be allowed. The primed porous aluminum panels shall be formed in adequate thickness and factory formed to specified dimensions.
2. Adhesion: The primed aluminum properties shall included, high shear strength, with adhesion levels greater than 8lbs per square inch.
3. Laminate : All exposed surfaces shall be of the laminate veneer, .006”. Grain dimensional texture shall be as selected by the architect. Laminate veneer and adhesives shall meet ASTM E84 Class I with Underwriter’s Listing UL. The laminate to be dimensionally stable .3 max. Chemically resistant to NEMA Standard 11-14-95. Abrasion resistant to meet ASTM-D1044.
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 ceiling panels or support tees. Down light openings and sprinkler holes shall be factory precision cut as required.
C. The plenum shall be 100% accessible. Every panel must be removable. Progressive panel access is not acceptable. Heavy duty torsion springs and clip assemblies to be mounted to every panel for downward access, without potential for damage to panel face or hinge assembly. Hinge assembly shall be attached to panel with minimum 2 flush fasteners. Attaching torsion spring directly to panel with fastener will not be accepted.
2.03 SUPPORTING GRID
A. Supporting grid system shall consist of straight, factory formed tee in adequate thickness, to support loads. Finish tee to be matte black where exposed. Tee shall be factory slotted to accept torsion spring attachment.
B. Ceiling suspension shall meet structural requirements as required in ASTM 635, ASTM 636, heavy duty direct hung ceilings.
C. Hanger attachments shall be 12 ga. pre-straightened steel wires, rods or other approved hanging device that will support required loads.
D. Tolerances: Maximum deviation of ceiling panels from edge to edge in width shall not exceed 1/4" in 10' when measured with a straightedge placed at any directional location on the finished surfaces. Maximum deviation shall not exceed 1/4" from level in any area or room.
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 ceiling manufacturer with minimum 5 years experience with products of the nature specified.
2. Attach supporting channels of adequate strength to construction above by approved connection method according to local building codes.
3. The contractor responsible for the work of this section shall be qualified and experienced in the performance of this work and done so for no less than a period of 5 years.
B. Product Handling
1. Delivery: Deliver metal ceiling components to job site in unopened containers identified with product manufacturer's name, trade name and other applicable identification.
2. Storage: Store all ceiling materials in dry and protected locations until installation.
3. Remove protective film material from panels only when space is completely clean and dust free of airborne particles. Cotton white gloves shall be used for final installation.
4. Remove and replace units that have been damaged or cannot be satisfactorily cleaned to the owner's or architect's acceptance, at no additional cost to the owner. To clean materials follow manufacturer's written cleaning procedures.
C. Maintenance
1. Maintenance instructions, as written by the manufacturer,
are to be left with the building owner.
