"Tyvek (tm) air barrier is sealed to the concrete and run up onto the sheathing before the foundation foam goes in. Then a z-flashing sits right on top of the foundation insulation, and is taped into the Tyvek. . And, this is Wisconsin.…"

Don Hynek replied to Jack Baikoff's discussion Vermiculite in the fireplace
"Our weatherization protocol (based on Wisconsin DHS rules) says there is no reliable sampling protocol for asbestos  in vermiculite. The reason (I am told)  is that the asbestos fibers laid in veins in the original ore, and not dispersed…"
