Apparatus and method for door and window side flashing

Abstract

A window and door side flashing is installed with a double self adhesive flashing. The flashing may be provided as a tape or sheets, with adhesive pre-applied to both sides of a substrate. Protective liners may be removed in strips from either side of the flashing in order to expose a desired width of adhesive for attachment to portions of door or window jamb, framing, brick mold, or exterior sheeting. Other areas of the flashing remain covered to permit easier handling and installation. After application, the flashing provides a continuous barrier to water intrusion. In other embodiments, an extruded plastic flashing is provided. The flashing may have flexible fins to seal against water intrusion.

       2 . The double self adhering flashing of  claim 1 , wherein the flashing is provided in a roll.  
   
   
       3 . The double self adhering flashing of  claim 1 , wherein the flashing is provided in a sheet.  
   
   
       4 . The double self adhering flashing of  claim 1  wherein the first segmented release liner is a plurality of separate strips.  
   
   
       5 . The double self adhering flashing of  claim 5  wherein a first strip overlaps an adjacent second strip.  
   
   
       6 . The double self adhering flashing of  claim 1  wherein the first segmented release liner is a perforated liner, such that the perforations are provided along parallel lines.  
   
   
       7 . The double self adhering flashing of  claim 1  further comprising at least one drain channel.  
   
   
       8 . The double self adhering flashing of  claim 1  further comprising a plurality of drain channels.  
   
   
       9 . A method of sealing between the side of a window or door jamb and the window or door frame, the method comprising 
 providing a double self adhering flashing comprising 
 a substrate having a first side and a second side,  
 a first adhesive layer applied to the first side of the substrate,  
 a second adhesive layer applied to the second side of the substrate,  
 a first segmented release liner applied to the first adhesive layer, such that one or more strips of the first segmented release liner may be selectively removed from the first adhesive layer, and  
 a second segmented release liner applied to the second adhesive layer, such that one or more strips of the second segmented release liner may be selectively removed from the second adhesive;  
   exposing a first portion of the double self adhering flashing and attaching the first portion of the double self adhering flashing to exterior sheeting in proximity to the door or window opening;    exposing a second portion of the double self adhering flashing, wrapping the flashing partially around the jamb framing opening, and attaching the second portion to the door or window jamb framing;    installing the door or window; and    exposing a third portion of the double self adhering flashing and attaching the third portion of the double self adhering flashing to the interior of the window or door.    
   
   
       10 . The method of  claim 9  further comprising applying an adhesive to at least one of the second portion of the double self adhering flashing or the third portion of the double self adhering flashing to allow time to adjust the window or door to a desired position before the adhesive sets.  
   
   
       11 . The method of  claim 9  further comprising removing a fourth portion of the flashing in proximity to the first portion, and wrapping the fourth portion over at least a portion of the brick molding of the window or door.  
   
   
       12 . The method of  claim 9  wherein providing a double self adhering flashing further comprises 
 providing the substrate with at least one drain channel.    
   
   
       13 . The method of  claim 9  wherein providing a double self adhering flashing further comprises 
 providing the substrate with a plurality of drain channels.    
   
   
       14 . A side flashing for sealing between a window or door jamb and the framed opening for the window or door, the flashing comprising 
 a first flange corner, such that the inside of the first corner faces toward the window or door jamb, the first flange corner comprising 
 an inside facing plate, such that a portion of the inside facing plate may seal against a portion of the inwardly facing edge of the window or door, and  
 a first jamb plate, such that the first jamb plate may be positioned between a portion of the jamb and a portion of the framed opening;  
   a second flange corner, such that the inside of the second corner faces away from the window or doorjamb, the second flange corner comprising 
 an outside facing plate, such that a portion of the outside facing plate may seal against a portion of the outside facing surface of the framed opening, and  
 a second jamb plate, such that the second jamb plate may be positioned between a portion of the jamb and a portion of the framed opening; and  
   a depth-adjustable attachment means connecting the first jamb plate to the second jamb plate.    
   
   
       15 . The side flashing of  claim 14  wherein the depth attachment means is a slidable overlapping joint between a portion of the first jamb plate and a portion of the second jamb plate.  
   
   
       16 . The side flashing of  claim 14  wherein the depth attachment means is flexible membrane having a first edge connected to the first jamb plate and a second edge connected to the second jamb plate.  
   
   
       17 . The side flashing of  claim 14  wherein a plurality of flexible fins are attached to the inside facing plate, such that the fins provide a seal between the window or door jamb and the inside facing plate.  
   
   
       18 . The side flashing of  claim 14  wherein a plurality of flexible fins are attached to each side of the outside facing plate such that a first portion the fins provide a seal between the outside facing plate and exterior sheeting, and such that a second portion the fins provide a seal between a window or door flange and the outside facing plate.
