The method of construction includes providing Asian cardboard and comminuting the cardboard into pieces of a predetermined size. Further, combining the reduced size pieces of cardboard with heat bondable textile fibers and staple fibers to form a substantially homogenous mixture, and then, forming a web from the mixture. Then, thermally bonding the constituent ingredients of the web to produce a matt of a desired thickness. Further, laminating a scrim layer to at least one side of the matt while maintaining the thickness of the matt as initially produced. |
