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: –
Compässo
™
Elite Extruded Perimeter Trim, factory curved and cut to form a cloud to the required size and shape
– 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
–
Compässo Elite extruded perimeter trim splice plates
– 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
Compositions. Restraints are not included in the kit.
Placement of
Compositions may obstruct or distort the existing or planned fire sprinkler water distribution
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
Compositions shall not exceed 4lbs. (1.81kg.). Thorough component and full
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.

Installation Guide
1 Follow good safety/industrial hygiene practices during installation. Wear appropriate personal protective
equipment. Read literature before specification and installation.
2 Determine the location of the hanger wires: For any type of cloud system this depends on the size and
configuration. In order to ensure proper hanger wire location refer to
Compositions Systems Guide IS267,
or included isometric with hanger points noted.
3 Determine finished ceiling height.
4 Install the main tees on the hanger wires. Level, but do not tie the hanger wires. The added weight of the
cross tees and trim will change the hanger wire position slightly so it is good practice to tie the hanger wire
after all the trim and grid is installed.
