Rehabilitation Guidelines 1982. 10: Guidelines on the Rehabilitation of Walls, Windows, and Roofs

摘要

These guidelines describe typical methods and procedures for rehabilitating many common types of walls, windows, and roofs in existing structures. They also present cautions appropriate to each type of material. The guidelines emphasize the retention of esthetic qualities as well as the preservation of structural integrity. A discussion of masonry explains procedures for cleaning, repainting, and the problems of various types of coatings. Guidelines on wood frame exterior walls focus on the rationale for preserving historic character, energy conservation, and the use of alternative materials like aluminum and vinyl siding. Wood windows are discussed from the standpoint of their significance, repairs, weatherization, and replacement. Roofing rehabilitation guidelines cover water protection, energy conservation, and maintenance. Photographs and 20 references are included. Appendices include draft guidelines on rehabilitating historic buildings, a list of sources on preservation, an explanation of techniques for repairing wood windows, and addresses of regional historic preservation offices of the National Park Service.
