[Greenbuilding] protecting outdoor wooden structure from future decay (or at least delaying it)

[John Salmen]

I agree - time for a rewrite on rot resistance for wood species. Most of it
was based on virgin growth heartwood and that is not around. Most of what is
available off the shelf now will rot regardless of species.  I also think we
need to rethink details. A drip cap at the base of vertical wood siding will
ironically direct more water to the end grain than if there was no drip
base. Problem is we want to see traditional details and some horizontal
lines.....

<If a vertical piece contacts a horizontal, it's hard to see that wicking
won't occur. Best would be an angled bottom cut with a minimum 1/8" space
and caulk set back from the face.>

 

agree, the drip cap in the cited failure had an appropriate slope--moreover,
it was d. fir, as we anticipated it would take a beating.  the vertical
pieces were clear white pine, which ought to be labeled Mold Food.
