Vinyl siding is typically less expensive than wood siding, particularly cedar. Hollow vinyl siding, which only consists of interlocking panels, is the least expensive vinyl option. Foamback vinyl, which has filler in the panels, costs more than hollow vinyl due to the cost of the additional material. Foamback vinyl is regarded as a higher-performance option than hollow vinyl. Wood siding typically costs more than either, with the least expensive cedar option being a little more expensive than foamback vinyl. Wood pricing depends on the style and size of the siding materials. Since there are many different wood siding options, there is a larger variability in price.
