Approximately 70% of all wood used goes into residential (50%) and non-residential (17%) construction. In the United States, by the turn of the century the volume of lumber used for these applications will exceed 100 billion bd.ft., of which 15 billion board feet will be 2"x8" and larger dimension lumber. This is the high priced end of the wood products spectrum. Consumption in Canada will be approximately one-tenth of this.
