MODULAR CELLULAR WOOD CEILINGS
Conwed's NaturaLines Modular Cellular Wood Ceilings provide an easily accessible ceiling, but allow for passage of air and light. The use of a cellular ceiling will aid in camouflaging mechanical and electrical systems behind, yet provide the warmth and beauty of wood. The panels are designed to lay into a standard 15/16" grid suspension system.

A. SCOPE
This section includes all of the NaturaLines Modular Wood Ceilings as manufactured by Conwed, in Ladysmith, Wisconsin, Phone: 800-932-2383 or FAX: 800-833-4798.

1. Use only select grade wood (red oak), (white oak), (maple), (aspen), (hemlock), (cherry), (mahogany), (cedar), or (customer requested wood species) in the construction of the NaturaLines Modular Cellular Wood Ceilings. The variation in color and grain will occur with each type of wood species and certain ranges of this occurrence should be sampled prior to acceptance as equal materials.

2. The NaturaLines Modular Cellular Wood Ceilings are constructed of (1/4"), (3/8"), (1/2"), (customer requested) thick blades x (2-1/4" - standard), (1-1/2"), (customer requested) high blades. Panel sizes shall be nominal (24" x 24"), (24" x 48"), (48" x 48"), (customer requested). Cell size shall be (3" square), (4" square), (6" square), (customer requested).

3. The NaturaLines Modular Cellular Wood Ceiling shall have a flush (lay-in) or recess (reveal or tegular) profile.

4. The suspension system between panels will be faced with matching veneer tape.

5. The NaturaLines Modular Cellular Wood Ceilings will be stained with (fruitwood), (walnut), (mahogany), or (customer requested) stain.

6. The NaturaLines Modular Cellular Wood Ceilings will be finished with (clear lacquer), (clear, Class A), (white pickled), or (customer requested) finish.

7. If acoustical absorption is desired, (1"), (1-1/2"), (2"), black faced glass fiber shall be installed above the NaturaLines Modular Cellular Wood Ceilings.

C. JOB CONDITIONS
1. Building must be enclosed and room conditions maintained equivalent to conditions when finished and occupied before any wood ceiling can be installed.

2. Ceiling material must be placed in the environmentally stable atmosphere 3 days prior and during installation to insure that wood ceiling panels have stabilized to those conditions.

3. The environment must remain constant at all times and not allowed to have drastic swings in temperature and humidity.

D. INSTALLATION
1. Install wood ceiling material only after all work has been completed above ceiling.

2. Conform to the recommendations of "CISCA Use and Practice" for the installation of suspended t-bar system.

3. Coordinate layouts and locations with other trades with respect to penetrations through ceiling systems.

4. Inspect and adjust wood ceiling panels to insure their proper location and attachment to suspension system are correct according to manufacturer's recommendations and practices.

5. Clean and touch up any exposed wood ceilings with matching finish provided by manufacturer.
