Installation Guidelines
IMPORTANT! PLEASE READ FIRST:
These suggested installation guidelines represent generally accepted procedures for successful installation of Kinetics Noise Control Gotham Deck-Suspended Ceiling Hanger for ceiling system isolation. These suggestions may be followed, modified, or rejected by the owner, engineer, contractor, and/or their respective representative(s) since they, not Kinetics Noise Control, are responsible for planning and executing procedures appropriate to a specific application. Kinetics Noise Control reserves the right to alter these suggestions and encourages contact with the factory or its representatives to review any possible modification to these suggested guidelines prior to commencing installation.
-
- 1. Installation of an isolated ceiling system that uses Kinetics Noise Control Gotham Ceiling Hangers requires 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. Anchors for mounting into non-isolated ceiling substrate (threaded rod if required).
- D. 1/2" or 5/8" thick gypsum board (Type X).
- E. Appropriate tools and equipment for installation.
-
- 1. Installation of an isolated ceiling system that uses Kinetics Noise Control Gotham Ceiling Hangers requires following materials (as specified by others and purchased separately):
Please note: If submittal drawings have been prepared for the installation, review drawings for completeness and accuracy; otherwise, refer to Selection Guidelines for selecting ceiling hangers.
-
- 2. Mark grid pattern on existing non-isolated ceiling using the following criteria:
-
- A. Isolators installed at the perimeter must be located not more than 12" from the edge of the isolated ceiling; maintain at least a three-inch clearance from the perimeter.
- 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.
-
- 2. Mark grid pattern on existing non-isolated ceiling using the following criteria:
Please note: Submittal drawings, if provided, override general location guidelines provided above.
- 3. Remove Gotham Hangers from box. Confirm capacity of each isolator to ensure proper location in grid. If provided, shop drawings will identify location of specific hanger by capacity rating. After determining the direction the cold-roll channel will run (orientation is not important acoustically), locate the isolators or threaded rod at the intersect points on the grid. Anchor isolators to non-isolated ceiling using appropriate fastener through the 3/8” diameter opening at the top of the pre-load spacer and hanger bracket. Slide cold-rolled channel through the channel clip of the leveling bolt. Position the cold-rolled channel to prevent contact at partition/wall/column or any other non-isolated structural component. Inter-connect ends of cold-rolled channel using appropriate practices for ceiling grid installation.
- 4. 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.
- 5. After assembling the ceiling grid, check for levelness. By loosening or tightening the bottom nut of the leveling bolt/channel clip, the grid can be adjusted to level. Do not overly loosen. A minimum 1/4" of threaded rod should be exposed above the threaded spring cap.
- 6. Install CPT perimeter interface at partitions/walls, columns, and around any non-isolated building components to create a 3/8" wide resilient layer that ensures the isolated ceiling remains decoupled from the non-isolated structure. As the gypsum board is attached to the grid, the springs will compress (1/2" to 1-1/4" nominally depending on spring capacity) allowing the ceiling system to lower into final position. Position the CPT to account for this change to final elevation. Trimming the CPT may be required following installation of the gypsum board. If an alternate method for ensuring that the isolated ceiling remains decoupled is employed (e.g., using resilient backer rod), be sure to maintain a 3/8" gap from non-isolated structural components
- 7. Install the gypsum board using accepted practices for attaching to the grid system. Be certain to maintain a 3/8" 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 gypsum board to rest on top edge of CPT; it should abut the perimeter isolation board. Do not allow the CPT to become compressed against the non-isolated structure. In some cases, additional adjustment of the gypsum board may be necessary to achieve levelness, consult factory for procedures.
- 8. Trim CPT as required and caulk gap using a resilient, non-hardening caulk.

-
- 1. Define ceiling area being isolated and sketch a layout showing the ceiling hanger locations per the following criteria (refer to layout diagram below):
-
- A. Isolators installed at the perimeter must be located not more than 12" from the edge of the isolated ceiling; maintain at least a three-inch clearance from the perimeter.
- 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.).
- D. Many room configurations will require non-conventional placement of isolation hangers to support the gypsum board ceiling (i.e., every isolated ceiling cannot be laid out in even rows in each direction). Consideration must be given to supporting the gypsum board ceiling adequately; this may require unique spacing arrangements to accommodate installation of the ceiling grid.
-
- 2. Once spacing of the ceiling hangers is determined and sketched, three (3) general areas of the ceiling require load calculations: mid-room, along the perimeter, and in the corners. The total number of calculations required depends on how varied the spacing of the hangers is in each of these areas.
- 3. Determine the total weight of the layers of gypsum wallboard and ceiling grid components being supported by the isolation hangers. The chart below is useful in determining common weights for materials used in isolated ceiling construction:
- 1. Define ceiling area being isolated and sketch a layout showing the ceiling hanger locations per the following criteria (refer to layout diagram below):
| Building Material | Weight (psf): |
|---|---|
| R11 (3-1/2" Fiberglass Batt) | 0.50 |
| 1-1/2" CRC and 7/8" DWF | 0.50 |
| 1/2" Gypsum Board (Type X) | 1.90 |
| 5/8" Gypsum Board (Type X) | 2.33 |
-
- 4. Additional items such as lights or a lay-in tile ceiling may be suspended from the gypsum board/ceiling grid assembly. The weight of these items needs to be considered when determining the appropriate number/capacity of hangers required.
- 5. Calculate load at each hanger location:
-
- ______lbs./hanger = Total psf of ceiling materials x SF area carried by each hanger
- Where, psf = pounds per square foot
- SF = square feet
-
- 6. Select appropriate hanger for each location from chart below. Designated model numbers indicate the load at which the isolator deflects one-inch (1") (nominal). Every hanger has at least a 50% overload capacity; it is possible to slightly exceed the maximum capacity shown in the chart below:
| Model | Spring Color | Capacity Range (lbs.) | Deflection Range (in.) |
|---|---|---|---|
| 12 | Silver | 6-12 | 0.50-1.00 |
| 18 | Yellow | 9-18 | 0.50-1.00 |
| 24 | Blue | 12-24 | 0.50-1.00 |
| 30 | Pink | 15-30 | 0.50-1.00 |
| 37 | White | 19-37 | 0.50-1.00 |
| 50 | Green | 25-50 | 0.50-1.00 |
| 75 | Black | 38-75 | 0.50-1.00 |
| 100 | Gray | 50-100 | 0.50-1.00 |
| 150 | Red | 75-150 | 0.50-1.00 |
| 210 | Brown | 105-210 | 0.50-1.00 |
Or maybe you want a key feature of our popular Muta hanger, a one-inch rated deflection spring in-line with a rubber element, but prefer installing CRC and drywall furring channel for the grid system. The channel clip and leveling bolt assembly make installation and leveling of the CRC grid system fast and simple. And after the weight of the noise control ceiling compresses the spring, an ample airspace is created between the concrete deck and the isolated ceiling.
Features
- Channel clip assembly carries cold-rolled-channel (CRC) grid system
- Built-in ability for leveling the ceiling’s framing grid
- Easily attached to the deck using a single fastener
- Capacities up to 210 pounds
- A level ceiling can be designed easily with Gotham’s ten (10) different spring capacities
