CGC's Sheetrock® Mold Tough® Ultralight Gypsum Drywall Panels are engineered to provide enhanced performance in moisture-prone areas while being significantly lighter than traditional drywall. This panel features a unique core formulation that combines gypsum with a high-performance mold-resistant additive, making it highly effective at resisting mold and mildew growth. The Ultralight construction simplifies handling and installation while reducing transportation costs due to its lighter weight. Designed for use in both residential and commercial environments, it excels in areas like bathrooms, kitchens, and basements where moisture is a concern. When tested in accordance with ASTM D3273, Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber, the panels meet or exceed ASTM C1396 specifications.
