Air sealing and insulating a poured concrete basement
I'm hoping to use poured concrete basement walls and wish to know weather I need to & if so how to air seal them. I want to use rigid rock wool as insulation. I also want all insulation on the inside of the concrete. The concrete basement walls support the outer of double stud walls and the roof/ceilings while interior basement walls support floor framing and the inner of the exterior walls. I
realize, of course, the concrete walls need to be designed to restrain back fill without bracing by the floor as is typical.

Does anyone know if there is a manufacturer that makes an energy efficient, dual HVAC/ ventilation system that would satisfy both of my needs and eliminate the need for 2 duct systems?
