Edge closure for roof systems

Abstract

An edge closure for installation on a roof structure is fabricated as an integral unit from a non-corrosive, durable material. The edge closure includes an anchoring flange for attachment to the roof structure, an upper flange with an upper longitudinal edge zone, and intermediate panel spanning between the anchoring flange and the upper flange, and a fascia portion integral with the anchoring flange and extending downwardly to a lower longitudinal edge zone. The anchoring flange and upper flange are spaced apart for receiving a thickness of insulative lightweight concrete therebetween. The upper and lower longitudinal edge zones are angled to provide added rigidity and strength to the edge closure.

1 . An edge closure for installation on a roof structure, wherein the roof structure includes a thickness of insulation, said edge closure comprising:
 an anchoring flange structured and disposed for attachment to the roof structure;   an upper flange spaced above said anchoring flange to define an area of depth therebetween for receipt of the thickness of the insulation between said upper flange and said anchoring flange, and said upper flange including a longitudinal edge zone positioned at an angle relative to a remainder of said upper flange;   an intermediate panel spanning between said anchoring flange and said upper flange; and   a fascia panel integral with said anchoring flange and extending downwardly therefrom and terminating at a lower longitudinal edge zone, and said lower longitudinal edge zone being angled outwardly relative to a remainder of said fascia panel.   
   
   
       2 . The edge closure as recited in  claim 1  wherein said longitudinal edge zone of said upper flange is angled downwardly relative to the remainder of said upper flange. 
   
   
       3 . The edge closure as recited in  claim 2  wherein said longitudinal edge zone of said upper flange is angled downwardly for biting into the thickness of insulation. 
   
   
       4 . The edge closure as recited in  claim 1  wherein said longitudinal edge zone of said upper flange and said lower longitudinal edge zone of said fascia panel are angled for providing added rigidity and strength to said edge closure. 
   
   
       5 . The edge closure as recited in  claim 1  wherein said intermediate panel includes a plurality of vent holes for venting moisture and gases from within the roof structure. 
   
   
       6 . The edge closure as recited in  claim 1  wherein said anchoring flange, said upper flange, said intermediate panel, and said fascia panel are formed as an integral unit from a single sheet of material. 
   
   
       7 . The edge closure as recited in  claim 6  wherein said single sheet of material is galvanized steel. 
   
   
       8 . The edge closure as recited in  claim 6  wherein said single sheet of material is steel. 
   
   
       9 . The edge closure as recited in  claim 6  wherein said single sheet of material is aluminum. 
   
   
       10 . The edge closure as recited in  claim 1  wherein said anchoring flange, said upper flange, said intermediate panel, and said fascia panel are formed as an integral unit. 
   
   
       11 . The edge closure as recited in  claim 10  wherein said integral unit is formed of plastic. 
   
   
       12 . The edge closure as recited in  claim 1  wherein said upper flange extends from said intermediate panel and terminates at said longitudinal edge zone, and said anchoring flange extends from said intermediate panel and in spaced, parallel relation to said upper flange, and said anchoring flange extends a greater distance than said upper flange from said intermediate panel. 
   
   
       13 . An edge closure for installation on a roof structure, wherein the roof structure includes a thickness of insulation, said edge closure comprising:
 an anchoring flange structured and disposed for attachment to the roof structure;   an upper flange spaced above said anchoring flange to define an area of depth therebetween for receipt of the thickness of the insulation between said upper flange and said anchoring flange, and said upper flange including a longitudinal edge zone positioned at an angle relative to a remainder of said upper flange;   an intermediate panel spanning between said anchoring flange and said upper flange;   said anchoring flange extending from said intermediate panel and terminating at a distal longitudinal edge to define a width of said anchoring flange measured from said intermediate panel to said distal longitudinal edge;   said upper flange extending from said intermediate panel to a distal longitudinal edge of said longitudinal edge zone to define a width of said upper flange measured from said intermediate panel to a said distal longitudinal edge of said longitudinal edge zone;   said width of said anchoring flange being greater than said width of said upper flange; and   a fascia panel integral with said anchoring flange and extending downwardly therefrom and terminating at a lower longitudinal edge zone, and said lower longitudinal edge zone being angled outwardly relative to a remainder of said fascia panel.   
   
   
       14 . The edge closure as recited in  claim 13  wherein said longitudinal edge zone of said upper flange is angled downwardly relative to the remainder of said upper flange. 
   
   
       15 . The edge closure as recited in  claim 14  wherein said longitudinal edge zone of said upper flange is angled downwardly for biting into the thickness of insulation. 
   
   
       16 . The edge closure as recited in  claim 13  wherein said longitudinal edge zone of said upper flange and said lower longitudinal edge zone of said fascia panel are angled for providing added rigidity and strength to said edge closure. 
   
   
       17 . An edge closure for installation on a roof structure, wherein the roof structure includes a thickness of insulation, said edge closure comprising:
 an anchoring flange structured and disposed for attachment to the roof structure;   an upper flange spaced above said anchoring flange to define an area of depth therebetween for receipt of the thickness of the insulation between said upper flange and said anchoring flange, and said upper flange including a longitudinal edge zone positioned at an angle relative to a remainder of said upper flange;   an intermediate panel spanning between said anchoring flange and said upper flange;   said anchoring flange extending from said intermediate panel and said upper flange extending from said intermediate panel in spaced relation above said anchoring flange, and said anchoring flange extending a greater distance from said intermediate panel than said upper flange; and   a fascia panel integral with said anchoring flange and extending downwardly therefrom and coplanar with said intermediate panel, and said fascia panel terminating at a lower longitudinal edge zone, and said lower longitudinal edge zone being angled outwardly relative to a remainder of said fascia panel.   
   
   
       18 . The edge closure as recited in  claim 17  wherein said longitudinal edge zone of said upper flange is angled downwardly relative to the remainder of said upper flange. 
   
   
       19 . The edge closure as recited in  claim 18  wherein said longitudinal edge zone of said upper flange is angled downwardly for biting into the thickness of insulation.
