Foam composites and methods of preparation thereof are discussed. For example, the foam composite may include a polymeric material and a particulate filler, wherein the compressive strength of the foam composite is equal to or greater than 20 psi, the density is 4 pcf to 40 pcf, and wherein the thermal conductivity is equal to or less than 0.050 W/n K, the particulate filler may include fly ash. e.g., in an amount of about of 45% to about 75% by weight with respect to the total weight of the foam composite. The foam composite may be prepared from a mixture of a polyol, an isocyanate, the particulate filler, and a liquid blowing agent having a boiling point equal to or greater than 25° C. or 30° C.

Methods for producing building materials comprising a reinforced substrate are described herein. The method can include providing a substrate having a first surface and an opposed second surface, applying a fabric material to the first surface of the substrate, applying a hydrophobic polymeric woven mesh to the fabric material, applying a coating to the hydrophobic polymeric woven mesh thereby allowing the coating to penetrate the hydrophobic polymeric woven mesh and fabric material, removing the hydrophobic polymeric woven mesh, and curing the coating thereby bonding the fabric material to the first surface of the substrate. The substrate can include a polymeric material. In some embodiments, the substrate can include a polyurethane foam. The substrate can further include a filler. The hydrophobic polymeric woven mesh used in the building materials can be derived from alkylene monomers.
