Rapid changes in the siding materials industry have dated Army specifications for turnkey procurement of siding to be used on family housing. This investigation surveyed state-of-the-art sidings for information that would help update the specifications. Aluminum, steel, hardboard, and vinyl siding materials were evaluated based on (1) manufacturer's claims for performance and warranty and (2) field inspection of the different types in use. Despite the study's limited scope, some recommendations can be made to amend the current procurement procedures. For example: (1) a factory prefinished siding with a 15-year nonprorated warranty should be specified; (2) flexibility in material types should allow local selection for optimal performance in different geographic locations and to complement existing architecture; and (3) sidings should be installed in strict accordance with the manufacturer's instructions to preserve the warranty.
