Window sill flashing

Abstract

The present invention is directed towards a window sill flashing comprising a base having a substantially rectangular shape. A front flange projects perpendicularly downward from a front edge of the base and at least one side flange extends vertically from a side edge of the base. The side flange includes a front surface. The window sill flashing is made from a rigid homopolymer vinyl film.

1 . A window sill flashing, comprising: 
 a base having a substantially rectangular shape;    a front flange projecting perpendicularly downward from a front edge of said base;    at least one side flange extending vertically from a side edge of said base, said at least one side flange including a front surface; and    wherein said window sill flashing made from a sheet of rigid homopolymer vinyl.    
   
   
       2 . A window sill flashing according to  claim 1 , further including a rear, vertical rising wall projecting perpendicularly upward from a rear edge of said base.  
   
   
       3 . A window sill flashing according to  claim 2 , wherein said rear, vertical rising wall is located opposite said front flange.  
   
   
       4 . A window sill flashing according to  claim 1 , wherein said rigid homopolymer vinyl is a polyvinyl chloride.  
   
   
       5 . A window sill flashing according to  claim 1 , wherein said rigid homopolymer vinyl sheet has a gauge range between 7.5 to 35 millimeters.  
   
   
       6 . A window sill flashing according to  claim 1 , further including a silicone coating over said window sill flashing.  
   
   
       7 . A window sill flashing according to  claim 1 , wherein said rigid homopolymer vinyl sheet used to fabricate said window sill flashing is supplied from rolled sheet stock.  
   
   
       8 . A window sill flashing according to  claim 1 , wherein said base is devoid of imperfections.  
   
   
       9 . A method of installing a window sill flashing along a bottom portion of a window opening, said method comprising: 
 exposing said bottom portion of said window opening;    placing at least one window sill flashing along said bottom portion of said window opening;    securing said window sill flashing to said bottom portion of said window opening.    
   
   
       10 . A method according to  claim 9 , wherein said exposing said bottom portion of said window opening includes cutting away a cover on said window opening.  
   
   
       11 . A method according to  claim 9 , wherein said securing said window sill flashing to said bottom portion of said window opening includes applying adhesive tape to said window sill flashing.  
   
   
       12 . A method according to  claim 9 , wherein at least two window sill flashings are placed along said bottom portion of said window opening.  
   
   
       13 . A method according to  claim 9 , wherein one window sill flashing is placed along said bottom portion of said window opening.  
   
   
       14 . A method according to  claim 9 , further including cutting said at least one window sill flashing to a predetermined length.
