Thanks for all the replies. What I am doing is having a framing company build all the floor joists, roof trusses and wall panels. They will truck them out to my building site and put everything together. Part of the deal is housewrap. I am going to be using 2 X 4 construction with Foam Spray Insulation to an R21 in all the exterior walls. I asked the insulation sub and he does not recommend either way. He said he has sprayed some houses who will not use housewrap and others that will. Framing company said there is not enough information out on the type of insulation I will be using along with housewrap. The only thing bad I have heard is it will be too airtight......IMHO I think what would it hurt. One more thing to protect the sheathing just in case moisture gets behind the siding.

Now I still have to decide on the geothermal HVAC system. 22K for top of the line 5 ton system with horizontal closed loop system or around 12K for a good quality heat pump. The up front money is scary on the geo, but I have heard in my area it will pay itself back in 3 - 5 years. I just don't know if that will work with the budget. Very big decision for me that I am having a difficult time deciding on.

Going tomorrow to visit the local Pella window dealer. It will be between Fiberglass or Vinyl and I think I am leaning towards the fiberglass. They are more money, but not much more than vinyl and of course they are cheaper than wood.
