Abstract
A fenestration flashing system includes a body member having a planar header leg extending horizontally from a rearward end to a forward end, a vertical leg extending upward from the forward end of the header leg, and a positively-sloped drainage leg extending upwardly and rearwardly from a top end of the vertical leg. A termination member has a vertical termination leg for attachment to the back-up wall and a positively-sloped drainage leg to overlap and attach to the positively-sloped drainage leg of the body member. The termination member and the body member define a drainage path down and out of the wall cavity. A method of flashing a fenestration of a cavity wall or non-cavity wall is also disclosed.

A fire-shield flashing system for an exterior rough opening in a cavity wall having a header and side jambs, the system comprising:
- a body member having a planar header leg extending horizontally from a rearward end to a forward end, a vertical leg extending upward from the forward end of the header leg, a positively-sloped drainage leg extending upwardly and rearwardly from a top end of the vertical leg;
- a vertical termination leg extending vertically from a position proximate a rearward end of the positively-sloped drainage leg, wherein the vertical termination leg and the positively-sloped drainage leg define a downward drainage path to the vertical leg;
- and
- at least one jamb member for each of the side jambs, each of the at least one jamb member comprising:
- a jamb member face portion;
- a jamb member body portion continuous with and extending substantially perpendicularly from the jamb member face portion;
- and
- a jamb member tab continuous with and extending substantially perpendicularly from a top margin of the jamb member body portion,
- wherein when installed in the exterior rough opening of the cavity wall, the planar header leg extends towards the rearward end of the planar header leg at least partially across an underside of the header of the exterior rough opening, the vertical leg is disposed in an air cavity between an inner wythe and an outer wythe of the cavity wall, the vertical termination leg is attached to a cavity surface of the inner wythe, the jamb member body portion abuts one of the side jambs, the jamb member face portion abuts the cavity face of the inner wythe, and the jamb member tab portion overlaps the header leg of the body member.
A method of flashing an exterior rough opening in a cavity wall, the method comprising:
- providing one or more body members made of stainless steel and each having a planar header leg configured to extend horizontally from a rearward end to a forward end, a vertical leg extending upward from the forward end of the header leg, a positively-sloped drainage leg extending upwardly and rearwardly from a top end of the vertical leg;
- providing a vertical termination leg made of stainless steel and configured to extend vertically from a position proximate a rearward end of the positively-sloped drainage leg;
- installing the one or more body members along an entire width of the header with the header leg of each of the one or more body members positioned against and overlapping an underside of a header of the rough opening and extending forward of a cavity face of an inner wythe of the cavity wall, the vertical leg abutting or positioned in close proximity to a cavity face of an outer wythe of the cavity wall, and the vertical termination leg being fixedly attached to the cavity face of the inner wythe of the cavity wall;
- providing one or more jamb members made of stainless steel and comprising:
- a jamb member face portion;
- a jamb member body portion continuous and extending substantially perpendicularly from the jamb member face portion and defining an L-shape;
- and
- a jamb member tab portion continuous and extending substantially perpendicularly from a top margin of the jamb member body portion to define a second L-shape;
- and
- installing the one or more jamb members with each jamb member body portion abutting a jamb of the exterior rough opening, each jamb member tab portion positioned between and abutting the header leg of the body member, and the jamb member face portion abutting the cavity face of the inner wythe of the cavity wall.
