That looks like old Styrofoam that was sold in sheets. In the 60s, or earlier.
it usually degraded that way when exposed to UV light, you said that this was on the ceilings?
ODD.
Was this warehouse used with a forklift to store stuff.
Old Styrofoam would disintegrate like liquid if it got a drop of gasoline on it, and a poorly tuned forklift could have been adding gasoline to the air.
