      I am NOT as experienced as Garager on the actual construction, but I've been under alot of houses.

      Plastic on the ground "reasonably" covering everywhere seems to be very adequate in most cases.

      Unreasonable cases I've seen ended up with other water infiltration into the crawlspace.

      I've taken some building classes, and just like Garager says, one time they tell you this is the best thing to do with insulation, the next time they tell you to do something different.

      Last I heard here is that they were thinking of eliminating plastic over insulation. And no vents in a crawlspace.

      I'm not sure why but I do know that you need a certain amount of air exchange into any dwelling for comfort and for the health of the structure.

      Anyway, on the ground with non bug or rodent attracting weight to hold it down if necessary. My opinion.

        OK, hawk it took me a while but I found the perfect picture. Of course the picture on the right side is your finished results. Bank your plastic up as high as you can and fasten it. If there is cement as a skirting, tack the plastic up to the floor joist (make sure you fold the ends at least 3 times for a better grab, about a 1" fold should be efficient enough). I will place rocks/small boulders as weight around the entire perimeter or boards. This prevents the plastic from being pulled off the walls in the future. Because someone will go under and eventually mess it up, then they will not fix it, so place some weight down around perimeter.

        We don't have the bug problems here, so if I use boards I can use construction lumber. But if you have a buggy area, green treated lumber then. I have gravel pits every where around me, so small boulders are free for me.

        Here is the picture and what a nice job they did, so this should be your finished result look....

        Do not use duct tape, you wanna use something like Tyveck tape. This will survive longer..... Hawk, minimum of 6 mil plastic, that is also the minimum code requirement for plastic on the ground, but go thicker for a longer lasting result.

                    even the paper backing on the insulation states this. at least last time i checked

                    Agree with Rick, the moisture retardant paper facing (its not truly a barrier) should be toward the living space in almost all cases.

                    BUT, with a vapor barrier of 6mil plastic laid on the dirt right below, you would have two moisture traps with your insulation in between which then become a sponge retaining moisture and affecting its R value. So this one is a tougher than normal call but I'm thinking garager may be right in this application. He's certainly done more of them than me, I'm just going off my book learning from college when it comes to insulation and what I've seen done on various jobs.

                      Just for my information, would this then be a good candidate for unfaced insulation? i.e. bat insulation w/out a backer.
                      I put it all back together better than before. There\'s lots of leftover parts.

                          Hawk,

                          Twenty years, or more, ago one of my pals built a year-round house on the lake in Adirondack. While the lake is more crowded now it is still beautiful country up there.

                              Poly on the dirt is the way to go, we use 10 mill in the projects we do. We also use 2 lines of accuostical caulking and then tape. Cover the whold works with sand if possible and we use the small pation blocks to create a walkway to any areas that need service. The sand and blocks will help protect the poly for the long haul. Also when you are attaching the poly to the upper sides leave a lot of slack, when you put your ballast on you will be amased at how much the poly pulls down. My vote on the insulation would be to insulate the skirting if possible. don't use pink, go with sm foam as thick as you can afford and take your time and use a couple of cans of spary foam at the joints and hard to get at spots.
                              If you are adament about putting insulation into the floor joists then the only safe approach would be spray foam. Crawl space even with the poly in it will tend to be humid in summer when you are using the air in the house and vice versa in the winter so the dew point ends up in the insulation no matter what you do. You can make arguments for putting the pink in and out for and against but only time and you specific conditions will tell in the end result
                              Good Luck
