A process for producing a structural laminate comprising the steps of providing a composite article comprising a facing sheet adhered to a thin, substantially incompressible yet expansible mat of long, layered glass fibers, applying a foam-forming mixture to the glass fibers, positioning a second composite article or a facing sheet over the applied foam-forming mixture, passing the facing sheets having the mat and the foam-forming mixture therebetween through the nip of two rotating rolls, and foaming the foam-forming mixture. The structural laminate is useful in thermal insulating applications.

A structural laminate comprising: (a) a rigid foam having two major, substantially planar, substantially parallel surfaces, one of the major surfaces of the rigid foam being attached to a planar facing sheet, the facing sheet having an adhesive coating disposed on the inner surface thereof and interposed between the facing sheet and the rigid foam, and (b) a network of glass fibers wherein: (1) the glass fibers are distributed in the rigid foam, (2) the glass fibers are greater than one foot in length, (3) the glass fibers are arranged in layers, (4) each layer of glass fibers is substantially parallel to the facing sheet, and (5) the network of glass fibers is secured to the adhesive coating of the facing sheet through attachments between the adhesive coating and glass fibers of the network proximate to the adhesive coating.
