great but what about insulation up between the joists?
Crawlspaces, Basement spaces are permitted to be as low as 1950mm (6’ 5”) under beams and ducts, however at least 75% of the required floor area must be at least 2100mm (6’ 11”) high .
BS!!
There ya go plagerizing the work of others again!
To make it worse, you are posting non-US information (based on Ontario, Canada requirements) to a U.S. Message Board without disclosing that it is a Canadian regulation you are posting!
I am trying to determine how his information is relevant. 
It isn’t. It rarely ever is!
That’s another illustration, in another post, about another subject!
From past inspections do not wrap the vapor barrier around any steel or wood support posts. The vapor will rise up like a chimney and rust or rot the supports. You should terminate the vapor barrier on the support footing if possible.
