2 USG Exterior Ceiling Applications
USG provides five exterior systems for use in exterior environments that are not directly exposed to the weather such as under a soffit, parking garages, covered entrance or drive-through. They include the:
– Paraline® II Linear Metal Ceiling System1
– Paraline® Plus™ Linear Metal Ceiling System
– Celebration™ Metal Panel Ceiling System
– ZXLA™ with sheetroCk™ Lay-In Ceiling Panel ClimaPlus™
– USG™ Drywall Suspension System
These ceiling systems combine traditional modules, elegant linear pans, or metal panels combined with a specially engineered suspension system to create dynamic ceilings with clean, contemporary planes.
These guidelines outline the design considerations, test results and construction details for the installation of each USG exterior ceiling system. USG exterior assemblies were tested per: UL 580, UL 1897, TAS 202 and TAS 203, and listed in PEI Evaluation Report, PER-12055.

Wind Design Notes Miles per hour (MPH) versus pounds per square foot (PSF)
ASCE 7-10, Minimum Design Loads for Buildings and Other Structures, American Society of Civil Engineers/
Structural Engineering Institute (ASCE/SEI), contains a formula that converts wind speed into static pressure.
The formula is a comprehensive approach to include factors such as height or location of the building, or
directionality of wind loads affecting the structure expressed as:
q z = 0.00256 K z Kz t Kd V2
q z = velocity pressure evaluated at height z above the ground
K z = velocity pressure exposure coefficient
K z t = topographic factor
K d = wind directionality factor
V = basic wind speed
The approximate value of wind pressure (PSF) can be calculated without knowing all of the factors described
above by utilizing the simplified formula shown below.
p = 0.00256 V 2
p is the pressure (measured in psf)
V is the wind speed (measured in mph)
Wind load provisions of ASCE 7-10, are recognized in the 2012 International Residential Code (IRC) and the
2012 International Building Code (IBC). The information presented is correct to the best of our knowledge at the
date of issuance. Because codes continue to evolve, check with a local official prior to designing and installing a
ceiling system. Other restrictions and exemptions may apply.

Wind Resistance
Paraline II and Paraline Plus
Paraline ceiling systems may be used for sheltered exterior applications not directly exposed to the weather. The Paraline II and Paraline 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).1
Limitations: Finish is not UV-resistant; Paraline 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 Paraline 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 Paraline 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 Donn 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 Paraline and Paraline 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.

Wind Uplift Resistance for Exterior Soffits
USG Drywall Suspension System
USG has a selection of Drywall Suspension assemblies to accommodate the wind loads for most
applications. The system has been tested using applicable industry standards for wind uplift resistance
when installed in exterior soffits and canopies. For more information regarding test standards and online
resources, please refer to the Systems Overview section of this catalogue.
Only SheetroCk® brand exterior ceiling board, DuroCk® cement board and SeCuroCk® Glass Mat Sheathing are
suitable for exterior applications. Specific information for gypsum panel applications can be found at
usg.con and usgdesignstudio.com.
The following pages detail the components and their spacing which are necessary to achieve the different
uplift classifications, including compression post spacing, limiting plenum depths, and construction details for
the installation. The structure that the USG Drywall Suspension System is attached to shall be designed
to withstand the applicable wind loads and carry the soffit system total weight.
Note: Design wind loads vary with geographic region and building conditions, and must be determined by a
professional engineer or architect of record.
