Sources for calsil or foamglas block for sub-floor insulation - eastern NC local

[CoastalPizza]

Does anyone have local sources for calsil (e.g. Thermo-12 Gold or similar) or Foamglas One block for sub-floor insulation? I can get either from Commodity Construction but would prefer a local supplier.

Thermo-12: http://www.commodityconstruction.com...ck-insulation/
Foamglas: http://www.commodityconstruction.com...ck-insulation/

Thanks, Brian

While Charlotte is in the state, it is about a 5 hour drive. I was hoping for a supplier further east so I could save on shipping by picking it up myself.
