More about Historical Mineral Fiber Acoustical Ceiling Panels
Mineral Fiber acoustical ceiling panels are commonly specified with painted (ASTM E1264 Type III) or membrane overlay (ASTM E1264 Type IV) finishes. Ceiling panels are typically sold as 2x2 or 2x4 feet panels 3/4 to 1 inches thick. Raw materials typically include mineral fiber, produced from blast furnace and rock slags and coke, lightweight fillers like perlite, recycled paper, and binder(s) like starch and/or latex. The raw ingredients are mixed with water and slurry processing additives, such as flocculants, defoaming agents, and surfactants. The mixture is spread on a woven fabric scrim if a wet-felted panel or on a metal sheet if a cast panel and dried. For mold/microbial protection, water-based latex paints and primers are applied to the front and back of the panel. Antimicrobials are commonly used in these coatings and core. For additional fire protection, clay filler may be added to the core slurry, but was not included in this CP. Mineral wool ceiling panels can contain over 80% recycled content in the form of post industrial recycled blast furnace slag, used to manufacture mineral wool, post consumer recycled paper, and post industrial and/or consumer recycled ceiling tiles. Blast furnace slag and recycled paper content were captured in this CP. This CP characterizes an ASTM type III painted mineral fiber panel with antimicrobial.
