I'm building a 16 x 12 screened porch with very large (2'+) overhangs with gutters. Water will virtually never hit the floor although humid summers. Wondering what you real carpenters think about a southern yellow pine floor in this application. I have 3' clear air off grade and could do 6ml. poly.moisture barrier/ gravel if you think necessary. Vert. grain Doug. fir and Mahogany too expensive. Oak flooring reasonable $ too. Ever do an oak floor on a porch? Project is here in western CT. thx.
