I'm in the process of retrimming a few windows on my house. Originally there was just common white pine, and since that's what I'm used to using for soffit and fasica work, I'm going to replace it with the same.
I know that pine is not the best in terms of resisting rot and poplar is usually a no-no for outside, but my question is how much worse is poplar really than regular pine outside? As I said, I'm used to using pine for exterior trim work, and it's the norm around here (East Coast), but I'm curious if it's any better really than pine in terms of resisting rot, or if it's just cheaper and easier to work with, hence the popularity.
I have no plans on using poplar, but just curious why it in particular has such a bad reputation compared to pine.
p.s. That should read "trim" in the heading (I can't seem to edit that). J
