the foam and the fiber cement portions of the integrated fiber cement and foam insulation panel in various embodiments the adhesive can be applied onto the fiber cement layer by spraying roll coating etc the adhesive layer 106 may be discontinuous such as with partial coverage over the portion of the back surface 105 of the fiber cement layer 102 which mates to the profiled foam layer 104 to lead to a material and cost savings a discontinuous adhesive layer 106 may also facilitate the evaporation of moisture from the interface between the elongate fiber cement layer 102 and the profiled foam layer 104 in other embodiments the adhesive layer 106 may be continuous such as with full coverage over the portion of the back surface 105 of the fiber cement layer 102 which mates to the profiled foam layer 104 in another embodiment the profiled foam layer 104 may be joined to the fiber cement layer 102 by laminating the profiled foam layer 104 to the interior surface or back face 105 of the fiber cement layer 102 lamination may be achieved by mechanical means by use of adhesives or by forming the foam layer directly on the fiber cement layer either before or after curing of the fiber cement layer by autoclaving depending on the materials used in yet another embodiment the profiled foam layer 104 can be formed by applying a layer of foam generating liquid to the interior surface or back face 105 of the fiber cement layer 102 and allowing the layer of foam generating liquid to expand such that the.
