Wall/Roof Construction System and Related Method

Abstract

This invention comprises an insulative wall sheeting with purposefully overlapping barriers along all four lateral sides to a given sidewall sheet product hereunder. This system has moisture permeability and results in an improved installation method with an insulation rating of R2 or greater. The system comprises nonstructural sidewall panels that are preferably greater than about 1 inch thick.

What is claimed is: 
     
         1 . A rectangular sidewall panel sheeting system comprising an underlayment of base insulation material having an insulation rating of R2 or greater, said sidewall panel having a water barrier layer affixed to the underlayment of base insulation material, said water barrier layer overlapping about an entire perimeter of the underlayment of base insulation material by at least about ¾ inch, said overlapping water barrier layer of a first sidewall panel adapted for covering adjoining edges of one or more second sidewall panels. 
     
     
         2 . The rectangular sidewall panel sheeting system of  claim 1  wherein the underlayment of base insulation material is greater than one inch thick. 
     
     
         3 . The rectangular sidewall panel sheeting system of  claim 1  wherein the underlayment of base material is at least about 1 1/16″ thick. 
     
     
         4 . The rectangular sidewall panel sheeting system of  claim 4 , which has an insulation rating of R5. 
     
     
         5 . The rectangular sidewall panel sheeting system of  claim 1  wherein the underlayment of base material is up to about 4″ thick. 
     
     
         6 . The rectangular sidewall panel sheeting system of  claim 1 , which is non-structural and requires securing to another component rather than directly to a sidewall of a building construction. 
     
     
         7 . The rectangular sidewall panel sheeting system of  claim 1  wherein the water barrier layer overlaps use gravity to move waters away from adjacent panel joints. 
     
     
         8 . The rectangular sidewall panel sheeting system of  claim 1 , which is not suitable for use as a roofing construction panel. 
     
     
         9 . The rectangular sidewall panel sheeting system of  claim 1  wherein the water barrier layer overlaps the edge of the underlayment of base insulation material by about 1 to 2 inches. 
     
     
         10 . The rectangular sidewall panel sheeting system of  claim 1  wherein the water barrier layer affixes to the underlayment of base insulation 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. 
     
     
         11 . The rectangular sidewall panel sheeting system of  claim 1  wherein an overlapping region of the water barrier layer is supplied with an adhesive for serving as an air barrier. 
     
     
         12 . The rectangular sidewall panel sheeting 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. 
     
     
         13 . The rectangular sidewall panel sheeting system of  claim 11  wherein the adhesive is supplied to the overlapping region of the water barrier layer prior to installation of adjacent sidewall panels. 
     
     
         14 . The rectangular sidewall panel sheeting system of  claim 13  wherein the adhesive is supplied to the overlapping region of the water barrier layer by spraying. 
     
     
         15 . The rectangular sidewall panel sheeting system of  claim 13  wherein the adhesive is supplied the overlapping region of the water barrier layer by brushing. 
     
     
         16 . The rectangular sidewall panel sheeting system of  claim 1 , which further includes a radiant barrier layer coated thereon. 
     
     
         17 . The rectangular sidewall panel sheeting system of  claim 1 , which further includes a radiant barrier layer laminated thereto. 
     
     
         18 . A method for making an insulation sidewall sheeting panel system more water resistant and less wasteful, said insulation sidewall panel sheeting system including a plurality of rectangular base insulation sheet materials, each of said insulation sheet materials being greater than one inch thick and having an insulation rating of R2 or greater, said method comprising:
 (a) providing each of said plurality of rectangular base insulation sheet materials of the sidewall panel sheeting system with a water barrier layer that overlaps all four lateral edges of the rectangular base insulation sheet material, said water barrier layer being adhered to the rectangular base insulation sheet material and designed to fully cover each horizontal and each vertical lateral edge of adjacent rectangular base insulation sheet materials during installation of the sidewall panel sheeting system; and   (b) adhering at least some section of the overlapping water barrier layer of the rectangular base insulation sheet material to all lateral edges of the adjacent rectangular base insulation sheet materials.   
     
     
         19 . The method of  claim 18  wherein the water barrier layer adhered to each rectangular base insulation sheet material overlaps all four outermost edges of the rectangular base insulation sheet material by at least about ¾ inch. 
     
     
         20 . 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.
