Permanent Wood Foundations To the Editor: I was interested in Henry Spies' article on wood foundations in the August issue (page 25). It seemed to be thorough and carefully done in an effort to bring people up to date on the most important revisions. In one instance, though, I was surprised by an apparent omission. I refer to the text and detail on wood floors. Was the author discarding the American Plywood Association's "All-Weather Wood Foundation [now the Permanent Wood Foundation (PWF)] Details for Wood Basement Floor, Plan E" (Form E4306), revised April 1984, or was he unaware of it? This system strikes me as more sound than the detail he suggested. Elliott D. S. Adams Sharon Springs, N.Y. Henry
