new house insulation

[Guest guest]

Have a insulation question on new construction- humid side of VA

I won't go into all the traumas, both for myself and my builder- at

this point I wish I had purchased a travel trailer- but my builder is

now suggesting I use spray in foam insulation as a mold preventative

in the walls- his thinking- that the foam will adhere to the plywood

and studs, and will not absorb any humidity. Lets forget the VOC issue

at the moment - does anyone have any thought on whether this would be

an acceptable way to reduce mold growth within the structure?
