Abstract:
1. A thermal/acoustic flooring system comprising: a plurality of foam layers; and a filler material comprising a plurality of microparticles or nanoparticles randomly dispersed and completely separated from each other in each foam layer, wherein the filler material mitigates a magnitude of the external forces propagating through the plurality of foam layers, wherein the plurality of foam layers are placed on top of one another to form a multi-layered flooring system, and wherein the filler material has a particle size gradient throughout a thickness of the thermal/acoustic flooring system such that the filler material in a foam layer closest to an entry of the external forces into the flooring system has a particle size greater than that of the filler material in a foam layer furthest away from the external forces into the flooring system.
