Ceilume is the leading manufacturer of thermoformed ceiling tiles and panels, sized to fit standard 2x2 and 2x4 suspended ceiling grids that are widely used in commercial, institutional, retail, hospitality, and health care environments. These three-dimensional tiles and panels are available in forty different patterns to complement virtually any architectural style, with thirteen color and finish options and three diffusions of Transluminous® materials for making luminous ceilings. They can provide acoustic control up to NRC= 0.85, are Greenguard Gold certified for indoor air quality, and are made in the USA. The company’s roots go back to the pioneers of modular ceilings, when “Mid-Century was Modern.” The family-owned business is located in California’s wine country and in a repurposed historic apple-packing warehouse. With an eye on the future, Ceilume’s research and development continues to improve interior finish systems to meet changing environmental, performance, and aesthetic needs.
