Pan flashing with sill wedge and window clip

Abstract

The subject invention provides a system of accommodating flanged widows utilizing a novel pan flashing system in conjunction with a sill wedge, pre-formed corner flashing members and also the use of a novel clip for extending the length of the bottom window flange. The novel flange clip is preferably made from a heavy gauge galvanized material in a unique configuration, WillFlash® Flange Clips provide bottom support to the window unit, eliminating the need for shims that may also lead to damaged pan flashings in the sill area. Additionally, the Clips act as spacers to allow the pan flashing to drain, preventing bulk water form being trapped by the lower window flange. Moreover, each Clip is provided with weep holes to avoid trapping moisture/water in the interior of a u-bend formed by a pair of interconnected spaced vertical members.

1 . A combination of flashing elements for reducing the penetration of water around a rough opening with a flanged window installed therein, said combination comprising: 
 a rough window opening including a header, side jambs and a rough opening sill plate;    a pan flashing installed across the width of the window opening above said sill plate with a sill wedge member therebeneath;    said pan flashing comprising a self-adhesive backed flashing installed across the rough opening with vertical slits at the jamb studs folded into the rough opening over said sill wedge and terminating in a back dam;    a flanged window inserted in said rough window opening wherein the fasteners used to attach the flange below the window sill may not properly align to penetrate into said rough opening sill plate; and    flange clip means operably mounted on said lower window flange for effectively extending the length of the window flange below said window sill whereby fasteners can be effectively inserted into said window sill without fear of damaging said pan flashing.    
   
   
       2 . A combination of flashing components as defined in  claim 1  wherein said flange clip means comprises two flange clips, each having a pair of spaced parallel vertical members interconnected by a u-bend at their lowermost ends and a right-angled flange portion at their uppermost ends thereof, said spaced parallel vertical members providing a pocket for receiving said lower window flange therebetween.  
   
   
       3 . A combination of flashing elements as defined in  claim 2  wherein each of said flange clips further serves as a spacer for said lower window flange thus allowing said pan flashing to drain, preventing bulk water from being trapped by said window flange.  
   
   
       4 . A combination of flashing elements as defined In  claim 3  wherein each of said flange clips includes pre-drilled holes that serve to receive fasteners for attachment to said sill plate of said rough opening.  
   
   
       5 . A combination of flashing elements as defined in  claim 4  wherein the number of pre-drilled holes in each of said flange clips is two.  
   
   
       6 . A combination of flashing components as defined in  claim 5  wherein each of said flange clips further includes a plurality of weep holes at its lowermost portion thereof.  
   
   
       7 . A flange clip for supporting a flanged window in a rough opening of a building structure, said flange clip comprising: 
 a pair of spaced parallel vertical members interconnected by a u-bend at their lowermost end thereof;    each of said spaced parallel vertical members having a right-angled flange portion at their uppermost ends thereof with said flange portions extending in opposite directions;    said spaced parallel vertical members forming a pocket for snugly receiving a window flange therebetween and effectively extending the length of the window flange.    
   
   
       8 . A flange clip for supporting a flanged window as defined in  claim 7  wherein said u-bend includes at least one weep hole to avoid trapping water in the interior of said u-bend.  
   
   
       9 . A flange clip for supporting a flanged window as defined in  claim 8  wherein said spaced parallel vertical members includes aligned apertures in each of said parallel vertical members for receiving fasteners.  
   
   
       10 . A flange clip for supporting a flanged window as defined in  claim 9  wherein said clip is made of galvanized steel.  
   
   
       11 . A flange clip for supporting a flanged window as defined in  claim 9  wherein said clip is molded of plastic.
