What is the best way to insulate a 2x8 wall?
...foil face would be good, may not be breathable...might be better to just do eps board and buy attic foil to put over that .....this might be the cheapest way to get some insulation on the out side of the building for the thermal break .....rock wool would be good if I could find 4x8 sheets and do a price comparison. So...
