In at least some implementations, a foam product includes 50% to 75% by weight thermoset, between 1% and 10% by weight colorant, between 1% and 3% by weight blowing agent, and one or more fire retardant additives embedded in the foam. Such a foam product may be used, for example, as a board, tile, shingle, shake, or other component for an interior or exterior portion of a residential or commercial structure. In the examples of shingles, shakes, tiles and the like, the foam product may be used on a roof or any other desired portion of a structure, and it may be used for decoration, protection and/or insulation of the structure.
