PURPOSE: To provide method and device that can simply package an insulating product, store or transport a load without a particular protective means, conduct these at a relatively low cost, and further recycles the whole component members as much as possible.

CONSTITUTION: This comprises processes that dispose a pallet 1 upright, that form the first layer by laying a plurality of insulators horizontally, letting them mutually adjacent in a contact state to dispose laterally facing together and letting them in contact with the standing pallet 1, that form at least the second layer by superposing a plurality of insulators on the first layer, that dispose the pallet 1 at a horizontal position by rotating a load composed of the first layer and at least the second layer by 90°, that disposes a cover on the upper part of the load, and that unitize the load by packaging circumference of the load with a film.
