Polymer composite materials and methods of preparation are discussed. The composite material may comprise a polyurethane foam and a plurality of inorganic particles dispersed in the polyurethane foam. The composite material may have moisture movement properties, such that (a) a sample of the composite material having a length of 48 inches has a moisture movement of less than 0.15% along the length, and/or (b) a sample having a length of 6 inches has a moisture movement of less than 0.8% along the length, when submerged in 45° C. distilled water for 14 days.
