Abstract: A siding system for efficiently increasing the longevity of an outer wall structure (i.e. siding, etc.) of a building. The siding system generally includes a siding assembly which includes a venting structure including a first support member and a second support member, wherein the first support member is attached to the second support member. A plurality of first passageways and a plurality of second passageways extend between the first support member and the second support member, wherein a first perimeter of the plurality of first passageways varies from a second perimeter of the plurality of second passageways. The venting structure is positioned between a first layer and a second layer of an outer wall structure to allow the layers to efficiently dry and prevent moisture from building up between the layers.
