door threshold in a 12″ wall
What is the best way to build an exterior door threshold in a 12″ thick wall? The floor is concrete, with a 4″ gap of XPS between it and the 8″ thick foundation. The concrete floor is the same level as the top of the concrete foundation. The door will probably be in an “innie” position, that is, flush with the interior wall. There may be a storm door in the “outie” position.
