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.
