Not a question but I thought others might appreciate the BEAM tool analysis ( I recently used to compare options.

    That's enlightening to say the least. Somewhat surprised how [relatively] low vinyl siding is, compared to the steel and fiber cement options.

    One question... what's the 'denominator' here? X sq. ft. of siding (at Y exposure, for the lap products)?

      Everything is by the face square footage so it's easy to estimate. I don't recall the overall square footage but the installation details for each material:

      Pine 1x6: flat (as if tongue-and-groove)
      Red cedar 1x6: flat (as if tongue-and-groove)
      LP Smartside: 5/16"
      Vinyl: 0.040" double 4.5" exposure
      Steel: 24 gauge (they have various options but I used the "average" option since we hadn't chosen a product)
      Fiber cement: 5/16". They have two options and I don't recall which one I used but I don't think it made a big difference either way.
