    I looked this up several months ago, the source I found indicated perlite is marginally better as an insulator. I don't think the difference is significant and probably varies with the prep (size of particles and how well "puffed" the perlite/vermiculite is). I think they are similar to handle as well. I'd choose just based on cost and ease of acquisition in your area.

      I'm with Maver. Everything I have read shows very similar thermal characteristics. My local Home Depot carries both, and the cost is also similar. I have always worked with vermiculite, so I cannot comment on which is easier, though I know of many builders who have used Perlite.

      I would base my decision on ease of acquisition as well.

        Since perlite is white, it's easier to see if the dry ingredients are thoroughly mixed before you add water. Otherwise, there's no real difference.
