1. An insulated paper product comprising:
two or more paper layers and insulating material, said insulating material comprising particles having an average particle size of less than about 1000 microns (μm), said particles comprising perlite, expanded perlite, perlite hollow microspheres, perlite microspheres, milled expanded perlite, perlite flakes, an aerogel, vermiculite, hollow expanded vermiculite, or any combination thereof, the two or more paper layers being bonded to one another so as to form an integral paper product,
wherein the integral paper product (i) has a non-uniform distribution of the insulating material therethrough and (ii) is repulpable,
wherein the insulating material has a material bulk density of less than 0.6 gram per cubic centimeter (g/cm3), and
wherein one or more paper layers within said two or more paper layers comprise the insulating material.
