Abstract
An elongated flange material for forming a flange and a method for use in sealing a non-flanged window, door, or other fenestration product in a wall opening, wherein the flange material comprises at least one top coversheet and at least one bottom coversheet with a pressure-sensitive adhesive layer sandwiched between the two coversheets, wherein the coversheets occupy an appreciable width of the flange but do not extend across the entire width of the flange and thereby are offset with respect to each other thereby providing opposing first and second exposed surfaces of the pressures sensitive adhesive layer.
Claims11
A self-adhering flange material, comprising at least one top coversheet and at least one bottom coversheet with a pressure-sensitive adhesive layer sandwiched between the two coversheets, wherein the coversheets occupy an appreciable width of the flange but do not extend across the entire width of the flange and thereby are offset with respect to each other thereby providing opposing first and second exposed surfaces of the pressures sensitive adhesive layer.
A method for installing a non-flanged window into a wall opening whereby the interface between the window and the wall is sealed, the method comprising the steps of:
- a) forming a piece of flange material by contacting the adhesive surfaces of a first and second length of flexible self-adhering flashing material along their length such that the adhesive surfaces are partially overlapped and two elongated pressure sensitive adhesive layers face in opposite directions;
- b) adhering one of the pressure sensitive adhesive layers to the top surface of the head of the window and to the outer surface of the upper portion of each jamb of the window such that the remaining pressure sensitive adhesive layer faces up and away from the head;
- c) forming two additional pieces of flange materials as described in step (a);
- d) adhering one of the pressure sensitive adhesive layers of each of the additional pieces of flange materials to the outer surface of the entire length of each jamb of the window such that the remaining pressure sensitive adhesive layers of the flanges face away from the window;
- e) installing the window in the wall opening such that the head of the window is located at the top of the wall opening and the remaining pressure sensitive adhesive layers extend outward from the wall;
- f) adhering the remaining pressure sensitive adhesive layers to the wall above and adjacent each jamb of the window, such that the flange adhered to the head of the window covers an upper portion of the flanges adhered to the jambs.
A method for installing a brickmold window frame having two window jambs having outer surfaces, a window sill, a window head and a brickmold frame having a back surface into an opening in a wall having an exterior surface whereby the interface between the window and the wall is sealed, the method comprising the steps of:
- a) adhering a first adhesive surface along a first edge-portion of a piece of flange material to the outer surface of one of the window jambs such that the line between the first edge portion and the remaining portion of the piece of flange material is positioned in the corner between the outer surface of the window jamb and the back surface of the brickmold frame,
- b) adhering a second adhesive surface along a central portion of the piece of flange material to the back surface of the brickmold frame,
- c) making a cut in the flange material flush with the window head directly above the adhered first edge portion and adhering the flange material above the cut to the back surface of the brickmold frame,
- d) repeating steps (a)-(c) on the other window jamb using a separate piece of flange material,
- e) installing the window frame in place in the opening in the wall,
- f) exposing a third adhesive surface along one side of the window,
- g) adhering the adhesive surface of a covering piece of flashing directly to the exposed third adhesive surface,
- h) repeating steps (f)-(g) on other side of the window.
