Poured wall foundation and insulation
Does it make a difference in the insulating properties of a poured wall foundation if it has a "brick patterned" finish on both sides of the wall as opposed to a "smooth" finish? Overall contact would be better between the rigid and concrete wall with the "smooth" finish, but does the "brick pattern" negatively affect the insulation properties of the wall in any way as a result of the non-contact areas? This would be new construction in zone 5 (cold climate). The wall will be insulated from the exterior as well with rigid ... this would be additional in a finished area of the basement.

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?
