Decorative Clouds
Installation Guide
Description USG Compositions™ are decorative ceiling clouds offered in convenient, ready-to-assemble kits. Compositions allow you
to create a custom look, accentuate an area or make a unique design statement. The suspension system, trim and
suspension wire is pre-cut and ready-to-assemble.
Each Kit Contains: –
– Suspension system and tee brace components pre cut
– Hanger wire, no. 12-gauge galvanized, soft-annealed, mild steel wire, cut to 6' length, in the amount
required for the installation
–
– Attachment clips to connect the trim to the suspension system components
NOTE: Pop-rivets, screws and hardware required for attachment to the structure are not included.
Compositions kits contain all of the components required to construct and hang a complete cloud except for
the screws or pop rivets needed to attach the clips to the grid members and the hardware needed for
attachment to the structure. Hanger wire needed for extended distances to the structure is not included.
Ceiling panels are ordered separately.
Many building codes require non-structural building components to be restrained. USG recommends
restraint in accordance with all local building code requirements. Please consult with the Authority Having
Jurisdiction over the project to determine appropriate restraint requirements for the installation of

pattern, or possibly delay the activation of the fire sprinkler or fire detection system. USG recommends
consulting a fire protection engineer, NFPA 13, and the local code authority for guidance on the proper
installation techniques where fire detection or suppression systems are present.
CAUTION: Ceiling panels used in
scale load tests were conducted to ensure performance with a variety of infill panels and loading conditions.
Use of panels weighing more than this stated limit could result in failure of suspension system components.
Solid wood panels are not recommended.
1 Follow good safety/industrial hygiene practices during installation. Wear appropriate personal protective
equipment. Read literature before specification and installation.

6 Install the perimeter tees followed by the tee brace. Be sure the system is level while installing the tee braces.
NOTE: It is important to install the cross tees first and then install the tee brace by fitting it onto the web
of the tee and then positioning it on the top surface of the tee. Fasten the tee brace with 1/8" pop rivets or
7/16" pan head screws through the four holes provided. Some systems require an additional tee brace on
the tee intersection located at the center of the ceiling system.

NOTE: USG recommends leaving the installed trim attachment clips unlocked in the trim channels until
the system is ready to receive the ceiling tiles. This allows the installer to position the tees as needed
during installation.
8 Prior to installing the perimeter trim snip off the cross tee clips by cutting them through the middle of the
hour-glassed shaped hole.

11 For main tees, adjust the attachment clips to the proper location by aligning them against the override feature
and temporarily clamping it. Use a hole punch to create rivet holes through the tee aligned with the two top
holes through the attachment clip.
12 Once the holes are punched, fasten the attachment clip to the tee with two pop rivets.

13 Prior to installing the straight trim pieces be sure to first slide the splice plates in the integral trim channels
flush with the edge of the trim so they do not extend beyond the end of the trim.
14 Install the straight sides next and position in place. Extend the splice plates to connect the trim pieces with
the splice plates installed slightly offset of the center of the connection.

15 Install the remaining end caps and check the system for squareness. At this point the attachment clips may
be locked into place. The attachment clips are locked by inserting a flat-blade or straight screwdriver into
the vertical slot in the clip and twisting clockwise keying the clip into the trim. Be sure all hanger wires are
securely wrapped.
16 Install ceiling panels after checking for system squareness.
