The Armstrong Ultima 1911 is a mineral fiber acoustical ceiling tile in a 24" x 48" size with a square lay-in edge for suspended grid ceilings. It has a fine, non-directional texture and a white finish with 88% light reflectance, which helps rooms stay bright with less artificial lighting. The 3/4" thickness and mineral fiber core are built for commercial spaces such as offices, schools, libraries and healthcare facilities, where sound control and clean looks matter. It sits at the top of Armstrong's ceiling line, above basic contractor-grade tiles, and is aimed at projects that want a smooth, uniform ceiling rather than a budget panel.
