There really is no such thing as a house built "to tight" . Most people that think this way do not understand how important it is to have a vapor barrier properly installed on the warm sides of insulated walls and ceilings.
Vapor barriers stop the warm moist interior air from penetrating into the insulated wall cavity and condensing on the cooler exterior surfaces.
House wraps are moisture barriers. They help stop rain and other outside moisture from damaging the structure when it gets behind the siding. And water will get behind the siding.
