Roger Lin wants a very tight house, tight enough to meet the Passive House standard of 0.6 air changes per hour under a blower-door test. Lin will be using insulated concrete forms, which combine rigid foam insulation and concrete. Will the walls be tight enough to pass the blower door test, or will he have to do additional air sealing?
