Abstract
A convective weep screed for draining water that penetrates exterior cladding of an exterior wall of a building away from the building and for removing moisture located in the space between the weather resistant barrier of the wall and the exterior cladding and for providing ventilation to the space between the weather resistant barrier and the exterior cladding. The weep screed provides a pathway to the space between the weather resistant barrier and the exterior cladding to permit water/moisture/moisture vapor that collects there to drain therefrom and to permit air to gain access to said space, thereby providing an uninterrupted pathway for air to ventilate and dry said space.
Claims29
A weep screed, comprising
- a vertical attachment flange having an upper end and a lower end,
- a primary ground flange extending outwardly at an obtuse angle from the vertical attachment flange, the primary ground flange having a downwardly extending outer end portion forming a drip line,
- a secondary ground flange extending outwardly at an obtuse angle from the vertical attachment flange, the secondary ground flange having an outer end portion, and the secondary ground flange being positioned on the vertical attachment flange between the primary ground flange and the lower end of the vertical attachment flange,
- a retaining flange formed on the primary ground flange, the retaining flange extending upwardly and in a plane substantially parallel to the vertical attachment flange, the retaining flange having an inside surface that faces the vertical attachment flange, and the retaining flange having an outside surface that faces away from the vertical attachment flange,
- the primary ground flange having at least one opening formed therein and extending therethrough,
- the at least one opening formed in the primary ground flange being located in a portion of the primary ground flange between the vertical attachment flange and the retaining flange, and
- a chamber defined by the primary ground flange, the secondary ground flange, and a portion of the vertical attachment flange extending between the primary ground flange and the secondary ground flange,
- the chamber having at least one entrance/exit port formed in and extending through the outer end portion of the secondary ground flange and/or between the outer end portion of the primary ground flange and the outer end portion of the secondary ground flange, and
- a recess comprising the entire space surrounded by the primary ground flange, the vertical attachment flange, and the retaining flange for communicating directly with space between a weather resistant barrier positioned on a backing wall of an exterior wall and exterior cladding of the exterior wall when the weep screed is in use on the exterior wall for permitting moisture located between the weather resistant barrier and the exterior cladding to drain from the space between the weather resistant barrier and the exterior cladding into and through said recess, from which said moisture may move into and through the at least one opening formed in the primary ground flange, then into and through the chamber, and then into and through at least one entrance/exit port to outside the exterior wall, and for providing ventilation to the space between the weather resistant barrier and the exterior cladding via air from said recess, said air moving into said recess by moving from outside the exterior wall into and through the at least one entrance/exit port, then into and through the chamber, and then into and through the at least one opening formed in the primary ground flange to said recess,
- said recess when the weep screed is in use on the exterior wall either being completely empty other than for moisture or air but permitting moisture and air to pass through it, or being completely empty other than for a porous drainage mat and/or starter strips, together with moisture or air but permitting moisture and air to pass through it.

In a wall having a backing wall, a weather resistant barrier positioned on the backing wall, and an exterior cladding, a weep screed for mounting on the wall, comprising
- a vertical attachment flange having an upper end and a lower end,
- a primary ground flange extending outwardly at an obtuse angle from the vertical attachment flange, the primary ground flange having a downwardly extending outer end portion forming a drip line,
- a secondary ground flange extending outwardly at an obtuse angle from the vertical attachment flange, the secondary ground flange having an outer end portion, and the secondary ground flange being positioned on the vertical attachment flange between the primary ground flange and the lower end of the vertical attachment flange,

- pathway means for providing a drainage path for moisture located between a weather resistant barrier positioned on a backing wall of the exterior wall and exterior cladding of the exterior wall to drain from between the weather resistant barrier and the exterior cladding to outside the exterior wall away from the building and for providing ventilation to space between the weather resistant barrier and the exterior cladding, when the weep screed is mounted on an exterior wall of a building,
- said pathway means including a recess comprising the entire space surrounded by the primary ground flange, the vertical attachment flange, and the retaining flange for communicating directly with space between a weather resistant barrier positioned on a backing wall of an exterior wall and exterior cladding of the exterior wall when the weep screed is in use on the exterior wall for permitting moisture located in the space between the weather resistant barrier and the exterior cladding to drain from the space between the weather resistant barrier and the exterior cladding into and through said recess, and for providing ventilation to the space between the weather resistant barrier and the exterior cladding via air from said recess, and
- said recess when the weep screed is in use on the exterior wall either being completely empty other than for moisture or air but permitting moisture and air to pass through it, or being completely empty other than for a porous drainage mat and/or starter strips, together with moisture or air but permitting moisture and air to pass through it.
