Ceilume is the leading manufacturer of thermoformed ceiling tiles and panels. The company's predecessor dates from the early 20th Century and was a pioneer in the invention of the modern suspended ceiling. The family-owned business is located in Graton, CA in the heart of California's wine country, and occupies a historic apple-packing warehouse. With an eye on the future, Ceilume has invested in advanced manufacturing equipment, including 5-axis milling machines to make its own tooling, and has an active research and development program to create improved ceiling systems to meet changing environmental, performance, and aesthetic expectations.
