The bracing on the joists, mainly. Draw an upside-down U, for the floor and two joists.
Now draw an X that goes entirely from the top corner down to the bottom edge of the joist for the braces. There's no *room* to put insulation there. The previous guy didn't even try. Insulation goes up to the brace, stops for about 3", and then starts until the next brace. The braces are not set at regular intervals, and then there is piping and a little wiring to worry about.
The solution is simple enough, I think - run a moisture barrier (also missing) by hand along the floor, tucking it around the braces. Nail board insulation along the bottom edge of the joists, making a box. (Turning the U into a square, with an X in it.) Fill the hole with blow-in insulation. Hand-insulate the parts with pipes and wiring to keep them accessible.
Which is fine enough, but a friend of mine is still dining out on his "how it took me one month and 6 different home improvement centers before I got the machine to blow in my insulation" story. Once we got to blow-in, we got to Somebody Else's Problem.
Plus, it terrified me to manuver around the two boards on edge that actually hold up the center of my floor, even though everbody tells me that they're just fine. They're not rotten or anything, I just kept having images of accidentally knocking one askew...
