Abstract
A method for manufacturing a laminated foam product in which first and second consolidated fiberglass sheets are adhered to a foam core. The consolidated fiberglass sheets are made of fiberglass commingled with a polymer fiber and pre-treated with heat and pressure. PUR/PIR foam ingredients are applied between the first and second consolidated fiberglass sheets to form a PUR/PIR foam. The foam may be manufactured by directly foaming onto the fiberglass sheets or by foaming between facer sheets and using an adhesive to secure the fiberglass sheets thereto. A sufficient adhesion between the fiberglass sheets and the foam core is required to produce a strong lightweight sheet material suitable for use as a structural building component in lieu of wood or the like. The composite product has excellent strength and lightweight characteristics.
