Hi guys. *My wife and I are in the late planning stages of building

I want foam insualtion in walls and attic. *She is ok with that. *What
we disagree about is how to do the attic.
Her ex-husband is a HVAC contractor. *He says we should use the " foam
the underside of the roof, seal the attic and semi condition it"
method. *Our builder agrees.
My problem with that is, why would I want to semi condition an area
the same size as my house if I am never going to use it for anything?
I want to foam the attic floor, and make sure the attic is well
venitaled. *Why is allowing my warm and cold air (that I am paying *to
heat and cool) to migrate up into my attic a good idea? *Isn't it more
efficient to keep that expensive air in the house by well insulating
the attic floor?
Can anyone give me advice on why my thoughts are wrong?
Not a Psychologist.
We live in the Mojave desert. A friend's new construction a few years
ago had the attic ceiling sprayed with ICYNENCE tm foam.
