An External Insulated And Fixed System (EIFS) and method for making the same. The method provides a cost effective procedure for constructing an EIFS that can meet current hurricane high impact test protocol, especially for non-combustible EIFS “Systems”. A reinforcing high impact layer of fiber glass mesh is eliminated, and a high-density compression molded expandable polystyrene board is provided that yields significantly improved impact resistance.

1. A substantially flat panel construct for use in buildings and adapted to be applied to building structural elements such as wall studs or the like, comprising:at least one layer of a high density compression molded expandable polystyrene board, having a density in the range of between 10 to 18 pounds per cubic foot, a layer of high impact reinforcing glass fiber mesh, said mesh having a density in the range of 11 to 22 ounces per square yard, a layer of a second expandable polystyrene board, said last named board having a density in the range 0.9 to 2.5 pounds per cubic foot, and a layer of reinforcing glass fiber mesh forming one outer surface of the panel construct and having a density in the range 3.5 to 6.5 ounces per square yard. 2. The construct of claim 1, wherein the high impact mesh forms the other outer surface of the construct.3. The construct of claim 1 wherein the high-density polystyrene board forms the other outer surface of the construct.4. The construct of claim 1 including a layer of gypsum board of at least one-quarter inch in thickness.5. The construct for an External Insulated And Fixed System (EIFS), comprising:a substrate system comprised of an exterior grade sheet of plywood, gypsum or other type of flammable or non-flammable board adapted to be attached to a metal or wood framing stud; a high density compression molded expandable polystyrene board, having a density in the range of between 10 to 18 pounds per cubic foot attached to the substrate; a high impact reinforcing glass fiber mesh, said mesh having a density in the range of 11 to 22 ounces per square yard attached to an exterior surface of the high density expandable polystyrene board; a regular, expandable polystyrene board, said board having a density in the range 0.9 to 2.5 pounds per cubic foot attached to an exterior surface of said glass fiber mesh; a layer of standard reinforcing glass fiber mesh having a density in the range 3.5 to 6.5 ounces per square yard attached to an exterior surface of the regular expandable polystyrene board; an aesthetic coating covering said exterior surface of said standard reinforcing mesh. 6. The construct of claim 5, wherein the high-density board is attached to the substrate by an adhesive base coat comprising a mixture of Portland cement with a polymer-based adhesive or a fiber-reinforced 100 percent acrylic-based adhesive.
