Vinyl-Faced Gypsum Acoustical Ceiling Panels

Gypsum acoustical ceiling panels are classified under ASTM E1264 as Type XX and come in a variety of ceiling patterns. Ceiling panels are typically sold as 2x2 or 2x4 feet panels with 1/2 inch thickness. Sound performance characteristics of these ceiling panels are determined by the noise reduction coefficient (NRC) (≤1) and ceiling attenuation class (CAC) (≤45). Gypsum may be obtained from natural as well as synthetic sources. Natural gypsum is mined. Synthetic gypsum is a by-product of flue-gas desulfurization (FGD), scrubber technology utilized at power plants to reduce sulfur dioxide emissions. FGD or synthetic gypsum use is typically reported as pre-consumer recycled content. Pre-consumer recycled content may also contain small amounts of industrial scrap gypsum. Additionally, products contain small amounts (<5%) of post-consumer recycled content, which is recycled paper used in the paper facing. Gypsum ceiling panels are constructed by combining gypsum, reinforcing fibers, lightweight aggregate(s), and binder into an aqueous slurry. The slurry is then faced with paper and other materials depending on the design and application. Due to its durability and cleanability, vinyl facing is commonly used. This CP characterizes ASTM E1264 Type XX vinyl faced gypsum ceiling panels made from 100% natural gypsum. Panels typically contain a majority of natural or a majority of FGD gypsum, depending on the manufacturing location. Where available, product literature such as environmental product declarations may list the pre- and post-consumer recycled content of panels by manufacturing location. High percentage pre-consumer recycled content likely indicates FGD as the primary gypsum used in the substrate.
