The Guastavino tile arch system is a thin-tile vault system introduced to the United States in 1885 by Spanish architect and builder Rafael Guastavino (1842–1908). It was patented in the United States by Guastavino in 1892. The Guastavino Fireproof Construction Company operated from 1889 to 1962, and was headquartered in Woburn, Massachusetts, in a building of their own design which still stands; their records and drawings are preserved by the Department of Drawings & Archives in the Avery Architectural and Fine Arts Library.
