Similar results for me last winter as well.  Just west of Richmond, VA.
No treatments on 10 colonies derived from swarms. 7/10 survived winter.

All hives had 2" under customized telescoping cover.  Plastic inner covers with no top vents.

2 colonies made with 2x lumber.
1 polystyrene hive.  
4 hives with permanently installed R10 on all sides.
