Composite building structures, such as foam core panels or the like. The panels comprise one or more foam core sections, preferably cores which include fire retardant additives. The exterior sheathing for the foam cores is a multiple laminate containing an inorganic filler material, such as glass fibers or ground carbonaceous or siliceous material; the filler is bound in place by a fire retardant, furan-based resin. The method includes forming a plurality of layers by depositing the resin and the filler alternately in a mold, thereafter placing boards or like core structures thereover and covering the exposed surfaces by multi-ply laminates of the fire retardant furan-based resin containing the glass fiber, carbonaceous or siliceous fillers. The method is also applicable to cover existing foam core installations used in building structures.

A building panel assembly adapted to provide thermal insulation, improved fire resistance and decreased degradation into combustible byproducts under high temperature conditions, said panel comprising, in combination, at least one rigid abrasion-resistant laminated facing sheet adapted to provide structural strength for said panel, and an insulating foam core portion, said facing sheet being comprised of a plurality of layers of a composite material, said composite material including a cured resin component, a fire retardant additive for said resin, and a glass fiber material embedded within and serving to reinforce impart increased structural strength and flexibility thereto, said foam core portion comprising a plurality of individual core sections each having one face portion disposed in facing relation to said facing sheet and an edge portion lying adjacent an edge on another of said sections, at least one longitudinally extending laminated separator disposed between and bonded to adjacent edge portions of said core sections, said separator also having a portion thereof bonded to a portion of said facing sheet, said separator comprising a plurality of layers of said composite material, said foam core portion also having exterior edges covered by a plurality of layers of said composite material, a major portion of said resin being a curable, furan-based polymer.
