Laminated vapor barrier material and methods of use
First Claim
1. A reinforced laminated layer vapor barrier material for being supported by fasteners at a plurality of mounting points in a building interior comprising a bottom moisture resistant material facing sheet, an uppermost backing sheet, an intermediate strengthening fiber array layer being constituted by a plurality of layers of strips of synthetic fibers of generally the same cross section and arranged in a criss cross diamond array to provide multi-directional strength, a plurality of laterally disposed and longitudinally spaced fastener engaging support strips of greater cross section than said synthetic fibers and integrally formed in the laminated layer intermediate said fiber array layer and said bottom sheet, an adhesive interconnecting all layers into a cohesive selfsupportive, layered and laminated vapor barrier material.

Abstract
A laminated vapor barrier for building insulation including a vapor impermeable bottom sheet and an uppermost backing sheet with an intermediate strengthening fiber array constituted by a plurality of layers of strips of crossedly disposed synthetic fibers, a plurality of spaced and laterally disposed thin supporting strips of a suitable material intermediate the fiber array layers and the bottom facing sheets, a preferably fire retardant adhesive interconnecting all layers into a cohesive self-supportive layered and laminated vapor barrier product, the product being adapted for operatively supporting layered insulating material to the interior underside of a metal building roof structure, or the like, having a plurality of spaced longitudinally extending purlins, interconnected with the building structure, a plurality of supporting hangers depending from the purlins, the vapor barrier material being interengaged with and mounted to the hangers by interengagement support between the supporting strips and supportive hangers, the vapor barrier, as installed, actively preventing moisture intrusion from a building interior from contacting and possibly penetrating the layered insulation material.

9. In combination, a reinforced laminated layer vapor barrier material for being supported by fasteners at a plurality of mounting points in a building interior comprising a bottom moisture resistant material facing sheet, an uppermost backing sheet, an intermediate strengthening fiber array layer being constituted by a plurality of layers of strips of synthetic fibers of generally the same cross section and arranged in a criss cross diamond array to provide multidirectional strength a plurality of laterally disposed and longitudinally spaced fastener engaging support strips of greater cross section than said synthetic fibers and integrally formed in the laminated layer intermediate said fiber array layer and said bottom sheet, an adhesive interconnecting all layers into a cohesive selfsupportive, layered and laminated vapor barrier material, said structure having a plurality of spaced longitudinally extending purlins, interconnected with the building structure, a plurality of affixed supporting hangers depending from the purlins, a batt of insulating material disposed between said purlins and said laminated vapor barrier, said vapor barrier being mounted over the external surface of said insulating batt of insulating material wherein said supporting strips are aligned with said hangers, said arrangement spacing said laminated vapor barrier from said purlins and preventing heat transfer therethrough.
