18 USG Exterior Ceiling Applications

Wind Resistance

C

elebration

ceiling systems may be used for sheltered exterior applications not directly exposed to the weather.

Celebration systems have been tested for wind load resistance. The two units of measure commonly used are
miles per hour (mph) and pounds per square foot (psf), equated by methods in ASCE 7, Minimum Design Loads for
Buildings and Other Structures, American Society of Civil Engineers/Structural Engineering Institute (ASCE/SEI).¹.

Limitations:

Finish is not UV-resistant; C

elebration

should not be installed where direct exposure to sun or

weather will occur, such as fascias or facades. Not suitable for areas subject to high concentrations of acid rain.
Indirect exposure to severe environmental conditions may shorten the lifespan of the product. The specific design
of exterior ceiling installations requires the review and approval of the architect or engineer of record. Please refer
to IC415 for more information about C

elebration

ceiling systems.

Technical Data

– Wind pressure presented in accordance with applicable test standards.

– Compression posts used for the tests were 3/49 EMT conduit.

Guidelines

– Building structure from which the C

elebration

system is suspended and spaced, as well as hanger wire and com-

pression post attachment methods, must be capable of withstanding the loads applied during wind conditions.

– Compression post shall be positively attached to the structure. For further information on the USG D

Compression Post, see pages 42–44

– Heavy duty main tees shall be used.

– Other materials can be used for compression posts, provided the compressive strength and attachment method

are approved for use by a local structural engineer.

– Architect’s details must cover design and location of expansion joints in addition to meeting all applicable building

code requirements.

Panel Size

The C

elebration

systems presented in this guide can accommodate all available panel sizes. The performance

values are not limited to a particular panel size. All available panel sizes will meet the performance values
presented.

¹ System is to comply with local wind load requirements. The engineer of record shall determine the final recommendation

for the design wind pressure requirements of each project.
