Composite floor for an insulated or semi-insulated trailer including a unitary subfloor member and a unitary top floor member with a rigid foam core being located therebetween. The foam core has sufficient strength to transfer a cargo load from the top floor member to the bottom floor member without additional floor sills being located therebetween. The invention is further embodied in an improved method of manufacturing a floor as set forth above.

[ What is claimed is:] [1.] A composite floor for an insulated trailer, said floor comprising:a unitary subfloor member, said subfloor member having an upper surface and a lower surface;a unitary top floor member, said top floor member having an upper surface and a lower surface;a rigid foam core extending substantially uniformly across the lateral width of the floor, said core being sandwiched between the upper surface of the subfloor member and the lower surface of the top floor member wherein said foam core has sufficient strength to transfer a cargo load from the top floor member to the subfloor member without additional support structure interconnecting the top floor member and subfloor member; andwherein said subfloor member is configured without defining any holes therein to prevent fluid from entering the foam core.
