Abstract
A vessel for use in the transportation of cryogenic liquids in over the road cryogenic tankers has a double wall with a highly efficient, relatively light weight fiber glass insulation in the cavity between the walls. The fiber glass insulation increases in density from the inner wall of the cavity to the outer wall of the cavity having the least density adjacent the cold inner wall of the vessel which contains the cryogenic liquid and the highest density adjacent the outer wall of the cavity which is exposed to ambient conditions. One or more layers of reflective septa can be incorporated into the fiber glass insulation to reduce radiant heat transfer.
