ABSTRACT:
A subflooring composite is especially useful in a van. The composite comprises a plastic core having a thin planar bottom surface layer, a thin planar top surface layer and a series of substantially equi-spaced and generally vertically extending support walls connecting the bottom and top surface layers. A foam underlay is adhered to the plastic core's underside. The subflooring composite has good structural strength, insulation properties, and acoustic qualities. It is readily precut to abut against the interior vertical walls of the van.
