Material trends in residential decking Kostiw, Mark T.


Over the past two decades the North American market for residential decking has experienced significant growth that has been forecast to continue into the future. Materials commonly used for deck surfaces include; treated wood, naturally durable wood and wood plastic composites. While in the past ten years treated wood has held it’s portion of the market, naturally durable species have lost a significant share of the decking market. Wood plastic composites were introduced into the market in the early 1990’s and have experienced exponential growth that is predicted to continue into the future. Almost all decks built today are framed with treated lumber, however dissatisfaction with the quality and longevity of treated wood framing has left it susceptible to new market entrants. Recommendations are also provided for manufactures in the treated wood and wood plastic decking industry.
