Methods of making molded polystyrene articles are described. The methods include introducing steam into a mold simultaneous to filling the mold with foam particles, and cooling the mold without the use of cooling water. The method can be performed faster and with a lower temperature differential than conventional molding processes, permitting faster turn-around to the production of subsequent molded articles. The molded articles produced by the method can have thicker side walls, improved foam particle fusion, and improved compression properties as compared to conventional EPS molding processes.

The present disclosure relates generally to cladding for covering a building surface. The present disclosure relates more particularly a method of manufacturing a building surface panel. The method includes providing a foam piece having a 30 day/23? C. residual shrinkage of no more than 0.2%. The foam piece having the 30 day/23? C. residual shrinkage of no more than 0.2% is attached to a rear side of an outer shell so as to form the building surface panel. In some embodiments, a front side of the outer shell forms a visible surface of the building surface panel. The foam piece can be provided, e.g., by aging the foam piece for a time and at a temperature such that the 30 day/23? C. residual shrinkage is no more than 0.2%. The foam piece to be aged can, in some embodiments, be cut from a body of foam.
