thx alot!!..im kinda dense.
...and just to clarify...I do not need to use bubble wrap or vapor barrier(plastic)?? just the board or spray foam(which i'm assuming already functions as the bubble wrap and vapor barrier(plastic)?
and also same idea on the floor?? My initial plan was to build a sub floor ...so in order of layer id have metal bus floor..silver bubble wrap..panel board insulation..vapor barrier..and then boxcar wood siding for my floor..?? Sorry if I'm being repetitive..I have been really confused by this from many people....Mostly I'm confused If I need the bubble wrap in any situation and the plastic "vapor barrier"..
