Part  2:  Products

2.01  Materials

    A.  Suspended Ceiling Grid System

      1.  Acceptable manufacturer: suspended ceiling grid system - KEELGRIDâ - as manufactured by Keel Manufacturing, Inc., Sun Prairie, Wisconsin 53590  (800) 765-KEEL.

      2. Exposed ceiling grid components

        a.   12� (nominal) main runners, 4� (nominal), and 2� (nominal) cross tees manufactured from pultruded fiberglass.  1  3/8" wide face minimum.

        b.  PVC assembly and hold down clips manufactured from virgin PVC.

        c.  Pultruded fiberglass wall angles, 1 1/2" by 1 1/2", and1/10" thick. 

        d.  Main runner wall clips at fixed end.

      3.  Structural Considerations

        a.  The grid deflection shall not exceed .133" when subjected to a 7 pound per linear foot loading over a 4 foot unsupported span.

        b.  Grid system design shall accept dead load of 2.25 pounds per square foot with hanger wire at 4.0 foot on center or 3.00 pounds per square foot with hanger wire at 3.5 foot on center.

        c.  Grid tee members will have a 50% of the yield strength value as determined by a point load applied at the midpoint of a 4 foot simply supported span.  This 50% value shall exceed 40 pounds.

 
Part  3:  Execution

3.01 Inspection

    A.  The ceiling grid installer must examine the jobsite and conditions under which the suspended ceiling work is to be performed, and notify the Architect in a timely manner of any unsatisfactory conditions.

3.02  Preparation

    A.  Ceiling grid installer shall meet at the project site with the Architect and contractors from related trades working in the areas containing the suspended ceiling system prior to commencement of installation.

      1.  Review areas of potential interference and resolve conflicts before proceeding with the project.

      2.  Coordinate the work with the layout of other work that penetrates the ceiling.

      3.  Refer to the approved reflected ceiling plan for ceiling layout.

3.03  Installation

    A.  Install the ceiling in accordance with CISCA industry standards and the manufacturer�s printed installation guide.

    B.  A laser leveling device must be used to level ceiling.  Hanging wire must be straight or pre-straightened prior to use.

    C.  All light fixtures, equipment, air duct diffusers, filters, or ceiling penetrations must be   independently hung/supported
     

Flame spread and smoke development ratings are based on the E-84 tunnel test as performed by an independent testing laboratory.  These are comparison numbers for design, code and insurance considerations.  The tests are small scale tests and in some cases do not represent the hazards under actual fire conditions.  Fiberglass reinforced plastic will burn, as will other organnic based components, and will produce smoke.
