26 USG Exterior Ceiling Applications
Wind Resistance
ZXLA ™ Suspension Systems with s heetroCk ™ Lay-In Ceiling Panel ClimaPlus ™ may be used for sheltered exterior
applications not directly exposed to the weather. These 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: 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.
Technical Data – Wind pressure arrived in accordance with applicable test standards.
– Compression posts used for the tests were 3/49 EMT conduit.

Guidelines – Building structure from which the s heetroCk Lay-In Ceiling Panel 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.
– Other materials can be used for compression posts, provided the compressive strength and attachment method
are approved for use by a local structural engineer.
– Min. 6d common hold down nails or similar device shall be installed at regular intervals to prevent uplift.
Min. 6 for each 28 x 48 panel module and min. 4 for each 28 x 28 panel module.
– Min. 6d common hold down nails or similar device shall be inserted in alternating directions.
– Min. 6d common hold down nails or similar device may be installed through the hanger wire holes, cross tee
clip holes and through a field-punched hole in the web of the tee.
– Architect’s details must cover design and location of expansion joints in addition to meeting all applicable
building code requirements.
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.
