This system has moisture permeability and results in an improved installation method. The system comprises both structural and nonstructural panels, either insulated or non-insulated, in the form of wall and/or roof sheeting. ## Claims ### Claim 1 A rectangular construction panel sheeting system comprising an underlayment of base material having a water barrier layer affixed to the underlayment of base material, said water barrier layer overlapping about an entire perimeter of the underlayment of base material by at least about ¾ inch, said overlapping water barrier layer of a first construction panel adapted for covering adjoining edges of one or more second construction panels. ### Claim 2 (depends on 1) The rectangular construction panel system of claim 1, which is suitable for use as a wall underlayment. ### Claim 3 (depends on 1) The rectangular construction panel system of claim 1 wherein the underlayment of base material is structural and selected from the group consisting of wood and sheeting. ### Claim 4 (depends on 1) The rectangular construction panel system of claim 1 wherein the underlayment of base material is insulation. ### Claim 5 (depends on 2) The construction panel system of claim 2 wherein the water barrier layer overlaps the underlayment of base material on at least one horizontally extending lateral edge. ### Claim 6 (depends on 1) The rectangular construction panel system of claim 1 wherein the water barrier layer overlaps the underlayment of base material on all horizontally extending and all vertically extending adjoining construction panel edges. ### Claim 7 (depends on 1) The rectangular construction panel system of claim 1 wherein the water barrier layer overlaps use gravity to move waters away from adjacent panel joints. ### Claim 8 (depends on 1) The construction panel system of claim 1 wherein the water barrier layer overlaps the edge of the underlayment of base material by at least about ¾ inch. ### Claim 9 (depends on 1) The rectangular construction panel system of claim 1 wherein the water barrier layer overlaps the edge of the underlayment of base material by about 1 to 2 inches. ### Claim 10 (depends on 3) The rectangular construction panel system of claim 3 wherein the water barrier layer affixes to the underlayment of base material for the adjoining construction panels with at least one of: an adhesive and a mechanical anchor selected from the group consisting of a nail and a staple. ### Claim 11 (depends on 1) The rectangular construction panel system of claim 1 wherein an overlapping region of the water barrier layer is supplied with an adhesive for serving as an air barrier. ### Claim 12 (depends on 11) The rectangular construction panel system of claim 11 wherein the adhesive on the overlapping region of the water barrier layer is covered with a removable sheet of paper or cellophane. ### Claim 13 (depends on 11) The rectangular construction panel system of claim 11 wherein the adhesive is supplied to the overlapping region of the water barrier layer prior to installation of adjacent base materials. ### Claim 14 (depends on 13) The rectangular construction panel system of claim 13 wherein the adhesive is supplied to the overlapping region of the water barrier layer by spraying. ### Claim 15 (depends on 13) The rectangular construction panel system of claim 13 wherein the adhesive is supplied the overlapping region of the water barrier layer by brushing. ### Claim 16 (depends on 1) The rectangular construction panel system of claim 1, which further includes a radiant barrier layer coated thereon. ### Claim 17 (depends on 1) The rectangular construction panel system of claim 1, which further includes a radiant barrier layer laminated thereto. ### Claim 18 A method for making a construction wall panel system more water resistant and less wasteful, said construction wall panel system including a plurality of rectangular base sheet materials, said method comprising: (a) providing each of said plurality of rectangular base sheet materials of the construction wall panel system with a water barrier layer that overlaps all four lateral edges of the rectangular base sheet material, said water barrier layer being adhered to the rectangular base sheet material and designed to fully cover each horizontal and each vertical lateral edge of adjacent rectangular base sheet materials during installation of the construction wall panel system; and (b) adhering at least some section of the overlapping water barrier layer of the rectangular base material to all lateral edges of the adjacent rectangular base materials. ### Claim 19 (depends on 18) The method of claim 18 wherein the water barrier layer adhered to each rectangular base sheet material overlaps all four outermost edges of the rectangular base sheet material by at least about ¾ inch. ### Claim 20 (depends on 18) The method of claim 18 wherein at least some section of the overlapping water barrier layer is provided with an adhesive covered with a removable sheet of paper or cellophane.
