2. Applying vinyl or other synthetic materials.
Structures are historic because the materials and craftsmanship reflected in their construction are tangible and irreplaceable evidence of our cultural heritage. Substitute materials subtract from the basic integrity, historically and architecturally, of buildings. Historic materials should be retained wherever possible. Since wood has always been present in abundance in America, there is a richness and diversity of wood sidings in America. Therefore the wodd sidings become a recognizable part of the historic character of a building.
Often, during a restoration project, the replacement of wood siding is deemed necessary because it has deteriorated beyond repair. The concern with using vinyl or other synthetic materials to replace the original materials is a loss or severe diminishing of the unique aspects of the building. Applying synthetic material to a historic building can damage or obscure historic material, and more importantly diminish the historic identity of the building.
Though installation of artificial siding is thought to be reversible, often there is irreversible damage to the historic materials during the installation process. Furring strips are used to create a flat surface, "accessories" are needed to fit the siding around architectural features, and the existing wall fabric is damaged from the nailing necessary to apply the siding.
