woodster, Definate on the vapor barrier, Im actually putting 2" of high density Styrofoam over the plastic and have heat in the floor via a boiler.Thanks

Mobilus, its 36 x 66 with a 6 12 pitch and 18" overhang with a 10' ceiling height.Trusses on 4' centers. My lumber, Metal and insulation was $11,500. My Dad made that picnic table many a year ago.Thanks

snrub, I used a similar insulation in the pole barn I have now and it makes a big difference, I have found it performs better in the summer than winter. We are going to live in half of this one for a little while so I will be putting in a ceiling and inside wall with extra insulation.Thanks

And Thanks to all for the comments.Taking a couple of days break standing on that metal roof all day may calves are killing me.
