6 USG Exterior Ceiling Applications
Wind Resistance
Paraline II and Paraline Plus
P araline ceiling systems may be used for sheltered exterior applications not directly exposed to the weather.
The P araline II and P araline Plus 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 the methods in
ASCE 7, Minimum Design Loads for Buildings and Other Structures, American Society of Civil Engineers/
Structural Engineering Institute (ASCE/SEI).

Limitations: Finish is not UV-resistant; P araline 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 IC463 for more information about P
araline ceiling systems.
Technical Data – Wind pressure presented in accordance with applicable test standards.
– Compression posts used for the tests were 3/49 EMT conduit with compression post adapters.
Guidelines – Building structure from which the P araline system is suspended and spaced, as well as hanger wire
and compression 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 onn Brand
Compression Post, see pages 42–44.
– 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 P araline and P araline Plus 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.
