Abstract: A seamless siding made of vinyl, aluminum, or other sheet material strip is made by scoring flat material and punching fastener slots at the edges of the strip. The material is bent at the score lines to form a profile such as clap board or other desired style of siding. Fasteners through the slots hold the material to the wall while allowing the material to expand and contract in response to changing temperatures. The exposed surface may be embossed or textured as desired. The material provides a seamless siding with little waste compared to conventional wood siding products. No specialized expensive machinery, tools, or equipment is needed to carry out installation of this new siding product.
