USG Corporation (NYSE:USG), a leading building materials manufacturer, has received four Notices of Acceptance (NOAs) from Miami-Dade County in Florida for its exterior ceiling products. The recognition covers six systems and 33 assemblies, making USG a leader in this segment.  
This honor is significant; Miami-Dade County has among the strictest building codes in the country because of the severe weather the county faces, especially during hurricane season. 
“Miami-Dade’s building codes are viewed as the most stringent in the nation, especially as it relates to exterior wind ratings. As a result, many jurisdictions reference Miami-Dade’s NOAs as part of local code enforcement,” explained Yelena Straight, PE, Principal Research Engineer, USG Corporation. 
With four NOAs, USG holds the greatest number in the exterior ceilings category. This surpasses all competitors in not only the number of approvals, but also in the depth and breadth of product lines. 
“Receiving these NOAs is a true testament to the dedication and resources we commit to developing systems that meet the toughest building codes,” said Lee Tedesco, Senior Manager, Metal Ceiling Systems and Installation Specialists, USG Corporation. “This is the most coveted approval in the exterior ceiling business. We are pleased that we can provide systems that withstand the most stringent standards for the protection of buildings and the people in them.”  
USG provides systems for use in exterior environments that are not directly exposed to the weather such as under soffits, parking garages, covered entrances or drive-throughs. These ceiling systems combine traditional modules, elegant linear pans, or metal panels with a specially engineered suspension system to create dynamic ceilings. Included in the approvals are USG’s drywall suspension system and three metal exterior ceilings. The NOAs issued for USG Exterior Ceilings cover the following products:
