Additional Resources:

The TOPO™ 3-D Ceiling suspension system transforms flat ceiling planes into gently rolling landscapes. The system's uniquely expressive topography is created from pre-formed translucent or opaque panels that install easily into the narrow-profile DONN® TOPO suspension system. Different translucent values create distinct effects.

The system offers two depths (8" and 12) that create varying ceiling topographies. Translucent and opaque LEXAN® infill panels in five colors integrate easily with lighting for added visual interest and variation. It installs quickly and easily without field cutting. Optional pre-engineered utility circles accommodate lighting and utilities.

The narrow-profile (9/16" wide) DONN TOPO suspension system is offered in coordinated colors to complement panel finishes. The extruded aluminum suspension system can also be custom-painted. It features an integral clip on each cross-tee end that provides plug-in, positive-lock insertion for quick and easy installation without tools.

General

What two specialty ceilings can be used on the exterior?
PARALINE®and CELEBRATION™ systems can both be used for exterior applications. Both PARALINE and CELEBRATION systems can withstand wind conditions of up to 120 MPH.

Distribution and Handling

How should I store my specialty panels
Store panels in a manner that will prevent scratches or damage of any kind.
Will the panels bend if handled incorrectly?
Yes. Handle panels in such a manner as to ensure against racking, distortion or physical damage of any kind.

Installation

How far apart should hanger wires be spaced when installing grid?
Hanger wires should be spaced between 4' and 6' depending on how much load the grid will carry. Hanger wires that are spaced closer allow the system to carry heavier loads.
How much force is required to insert a cross tee with a quick release clip?
It takes 12-14 pounds of force to install a cross tee.
How is the spacing of wire hangers determined for fire-rated assemblies?
All systems must be installed and tested in compliance with ASTM C636.
What gauge hanger wire is needed to install grid?
For residential installation 18-gauge wire is required. For commercial installation 12-gauge wire is required.
When installing grid, what is the minimum clearance needed from the overhead structure?
Minimum clearance is 3", which allows ceiling tiles to be inserted and removed freely.
What is the best way to suspend a ceiling system beneath an existing grid system?
Attach transfer loading clips to the existing grid system.
How do you remove cross tees without a tool?
To remove a cross tee, push up on the main tee with your thumbs (where the cross tee is connected) and rotate it until the cross tee pops up and out of the slot.
How do you take main tees apart without a tool?
Facing the main tee splice place your left hand near the left side of the splice and right hand near the right side of the splice. Using a shearing motion, push with your left hand and pull with your right hand. This disconnects the main tee splice. Be sure to straighten the end tabs before attempting to reconnect.
Do you mechanically attach the SHEETROCK® Brand Liner Panels to the USG H studs?
No. The panels just slide into place.
Can I get installation videos for USG Specialty Ceiling Systems?
Yes. You can now order a video demonstration of the installation of Specialty Ceilings. Contact Samples & Literature for ordering information.

Performance

What is the standard warranty of grid?
Ten years. See complete warranty for details.
Which grid is the best grid to use in a Clean Room environment?
DONN® CE is the best grid for a Clean Room environment.
What are the best grids to use in an area that is accessible to moisture?
DONN® AX™ or ZXLA™.
What is the warranty for a system, that uses USG tile and grid together?
