This report summarises those issues embodied in building codes and product standards with implications for marketing solid wood siding in Canada and selected other countries. The intention is that technical knowledge gaps can be identified and possibly filled before marketing white spruce siding. Literature searches were done and personal contacts with experts in these countries were made in order to place siding in the context of international codes and standards. However database searches identified only a few documents related to the performance requirements of solid wood cladding products. These issues are discussed under three main headings: material and construction, fire resistance and durability, and weather protection. Apart from fire there is very little reference to solid wood siding in either North American or international building codes. It appears that the long use of the product has effectively been grandfathered in traditional siding application and use. This is, however, not the case for non-solid wood siding where a number of material-specific standards exist which ensure that the products have comparable performance to traditional products or to address performance deficiencies that are specific to that material. Wood siding use in new markets will not be grandfathered in, and there will probably be a need to develop standards and data similar to those for non-wood products.
