Without seeing the Bluelinx product, I don't know if it the same as BlueCor or not, but the basic specs are the same. Real BlueCor has a thin plastic film on both sides that adds much strength.

BlueCor is a bit more flexible and less brittle than Depron. Depron is flatter and more uniform than BlueCor, which often has slight ripples or waves in it (which you can see in the photos below). But BlueCor is much, much cheaper!

BlueCor is a Dow product intended as home insulation:
