A structural laminate comprises at least one planar facing sheet comprised largely of glass fibers but not having micro-glass as a filler. The facing sheet is self adhered to a rigid thermosetting plastic foam core. The non-glass filler material is chosen from a group consisting of clay, mica, talc, limestone (calcium carbonate), gypsum (calcium sulfate), aluminum trihydrate (ATH), antimony oxide, cellulose fibers, and plastic polymer fibers. The non-glass filler material improves containment of liquid plastic thermosetting polymer, and offers economic and safety advantages.

A thermosetting plastic foam laminate comprising: (1) at least one planar facing sheet comprising: (A) from 60% to 90% by weight glass fibers exclusive of glass micro-fibers, and (B) from 10% to 40% by weight non-glass filler material, and (C) from 1% to 30% by weight non-asphaltic binder material w

A thermosetting plastic foam laminate comprising: (1) at least one planar facing sheet comprising: (A) from 60% to 90% by weight glass fibers exclusive of glass micro-fibers, and (B) from 10% to 40% by weight non-glass filler material, and (C) from 1% to 30% by weight non-asphaltic binder material which bonds the fibers together and bonds the filler materials to the fibers; (2) a rigid foam integrally attached upon formation of the foam to the surface of a facing sheet, the rigid foam formed from a thermosetting catalyzed plastic reaction product capable of being foamed.
