Hi Karin, Gregory again . . . and again planning how your homes "envelope" will be made and will perform is something that a green design program must include before the studs are delivered to the site. You shouldn't have to make this decision . . . after all, when you bought your last car you didn't have to do research on what materials would be used in the transmission. There seems to be a lack of engineering in the process. Please give an update ?? Best..

Closed Cell Vrs Open Cell Insulation?Asked by Karin
