CHALKLINES

Following installation guidelines, mark hanger locations.

• RESILIENT INTERFACE

  Adhere Ceiling Perimeter Tape (CPT by KNC) to all perimeters and penetrations.* CPT prevents sound vibration from transferring from the isolated slab to the non-isolated structure.

  • 
  • 

• ATTACH HANGERS TO DECK

  Install hangers at grid intersections.

  • 
  • 

• CLOSE HANGER LEGS AND TIE WIRE

  • 
  • 

• COLD ROLLED CHANNEL AND DRYWALL FURRING CHANNEL

  Following normal industry spacing and standards, screw drywall furring into CRC.

  • 
  • 

• GYPSUM BOARD

  Attach gypsum board to drywall furring channel using normal means and methods.

  • 
  • 

• ACOUSTIC SEALANT

  If desired or per project specifications, add acoustics sealant (by KNC) at all CPT areas.

• Preparation
  • 1. Installation of an isolated ceiling system that uses Kinetics Noise Control IsoGrid ceiling hangers requires the following materials (as specified by others and purchased separately):

• • • A. 1-1/2" x 1/2", 16-gauge cold-rolled channel
    • B. 7/8" 20- to 25-gauge drywall furring channel
    • C. Appropriate wire (per local code)
    • D. Anchors for mounting wire into non-isolated ceiling substrate
    • E. 1/2" or 5/8" thick gypsum board
    • F. Appropriate tools and equipment for installation

Please note: If shop drawings have been prepared for the installation, review drawings for completeness and accuracy.

• Installation
  • 2. Mark grid pattern and ceiling hanger position on existing non-isolated ceiling using the following criteria:

• • • A. Isolators installed at the perimeter must be located not more than 12" and not less than 3” from the edge of the isolated ceiling.
    • B. Isolators may be located up to 48" along the perimeter of the isolated ceiling.
    • C. Isolators mounted mid-room (i.e., those isolators not at the perimeter) may be located up to 48" on center each way (o.c.e.w.); mid-room isolators should be spaced evenly in each direction.

Please note: Shop drawings, if provided, override general location guidelines provided above.

1. • 3. Remove IsoGrid Ceiling Hangers from box. Confirm capacity of each isolator to ensure proper location in grid by observing the small colored dot on the side of the rubber element (See chart below).

IsoGrid	Dot Color	Recommended Layers of Drywall	Maximum Capacity (lbs.)	Deflection Range (in.)
40	White	1	41	0.2
105	Green	2	106	0.2
160	Red	3	150	0.2

If provided, shop drawings will identify location of specific hanger by capacity rating.

1. • 4. Determine orientation of cold-roll channel, typically oriented along longest dimension of room (orientation is not important acoustically).
   • 5. Fasten IsoGrid ceiling hanger to a concrete ceiling with a power-actuated fastener such as a Hilti X-DNI general purpose nail with a Hilti R-23 washer or other fastener as allowed by the local building code.

Please note: A Hilti representative can help you select the proper length nail for your specific application by calling 1-800-879-8000.

For example: An IsoGrid 160 fastened to 2000-4000 psi concrete slab would require 1.5" of nail embedment to hold the desired load. Therefore a Hilti X-DNI 82P8 nail would be required.

• • 6. Squeeze legs of the IsoGrid bracket together
  • 7. Tie wire through the holes on both sides of the IsoGrid bracket using appropriate practices for ceiling grid installation.
  • 8. Position the cold-rolled channel at desired height. Prevent contact between cold-rolled channel and partition/wall/column or any other non-isolated structural component. Leave at least a 3/8" gap between cold-rolled channel and the non-isolated structure.
  • 9. Tie free end of wire around cold rolled channel using appropriate practices for ceiling grid installation.
  • 10. Attach drywall furring channel to cold-rolled steel and inter-connect the ends of the furring channel using appropriate practices for ceiling grid installation. Furring channel cannot contact non-isolated structural components. Leave at least a 3/8” gap between cold-rolled channel and the non-isolated structure.
  • 11. After assembling the ceiling grid, check for levelness. Loosen or tighten the wire to adjust the level of the grid.
  • 12. Install CPT ceiling perimeter tape around partitions/walls, columns, and any non-isolated building components to insure a 1/4” wide decoupling gap between the isolated ceiling and the non-isolated structure. CPT should be installed from approximately 7/8” below the bottom of the hat channel to the top of the cold-rolled channel
  • 13. Install the gypsum board using accepted practices for attaching to the grid system. Be certain to maintain a 1/4” gap between non-isolated structural components and the isolated ceiling to ensure that the gypsum board does not contact any non-isolated structural components. Do not allow the CPT to become compressed against the non-isolated structure.
  • 14. Trim CPT as required and caulk gap using a resilient, non-hardening caulk.
