1. A composite backer board for wet space construction, said board comprising:
a rigid foam core of a suitable thickness for wet space construction;
a polymeric adhesive layer fixed directly to at least one face of the rigid foam core;
a first fabric layer fixed directly to the polymeric adhesive layer;
a first polymer layer affixed to said first fabric layer in which the polymer layer is dimensionally stable parallel to said face of said rigid foam core; and
a second fabric layer affixed to said first polymer layer opposite said first fabric layer and forming a first face that is amenable to thin set mortar and related compositions in wet space construction.
