A guide to the materials used in architecture during the past century, as well as tips on building repair and restoration. With more than 200 illustrations, including a full-color photographic essay, it focuses on the history and conservation of modern building materials.

This is a definitive guide to the materials used in architecture during the past century, as well as tips on building repair and restoration. Over the concluding decades of the 20th-century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior's National Park Service and first published in 1995. Now, this invaluable guide is being reissued - with a new preface by the book's original editor. With more than 200 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminium, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume.
