GBlist: Concrete block

Terry Brennan wrote that concrete block leaked about the same as a 3/8 inch
hole. I've recently gotten an inquiry from some straw bale people here in
Portland wondering about air movement thru the stucco/cement coatings. Maybe
I'm missing something but how does AIR move thru cement?

PS: Terry, for your attic vent blocking why not try the softer foam used
sleeping pads (4 inch thick) I would think the amount of irregularity of
framing would make fitting harder foam difficult.
