A layered composite construction material includes a pair of outer layers of material including essentially continuous strand fiberglass mat which are separated by a pair of intermediate sandwich layers of material each being adjacent to a respective outer layer of material and including essentially eighteen ounce woven roving fiberglass mat and which are further separated by at least one internal layer of material which essentially includes spun fiberglass blanket which has fiberglass strands longitudinally disposed perpendicular to the other layers of material for facilitating even dispersal of a foam throughout all the layers of material to effectively secure and bind the layers of material. The internal layer of material can also include multiple layers of spun fiberglass mat each of which are separated by a pair of layers of material. The layered composite construction material is quite useful as a building component in building structures, in rail cars, in boats, in campers, and is quite useful as a substitute for the use of wood, metal, and cement. This construction material has an indefinite lifespan.

[ What is claimed is:] [1.]1. A layered composite construction material comprising:a pair of opposed distinct outer layers of material comprising a first orientation of finespun filaments of glass which includes a continuous strand of fiberglass mat;a pair of distinct intermediate sandwich layers of material separating said pair of opposed outer layers and each being disposed adjacent to a respective one of said pair of opposed distinct outer layers of material and comprising a second orientation of finespun filaments of glass which includes woven fiberglass mat;at least one distinct internal layer of material sandwiched between said pair of distinct intermediate sandwich layers of material and comprising a third orientation of finespun filaments of glass; anda foam binder permeated throughout all said distinct layers of material to securely bind together all said distinct layers.
