TL;DR: In this article, a masonry flashing for use in a cavity wall is described, with a drip edge formed by extending the flashing beyond the external surface of the outer wythe and manually forming the drip edge.
Abstract: A masonry flashing for use in a cavity wall is disclosed. The flashing has channels for draining water from the cavity while permitting entry of air into the cavity. The top surface of the flashing is covered by a protective member. The protective member is a scrim or, in the extruded form, an overarching portion of the flashing material. The protective member prevents the clogging of channels from mortar droppings and other construction debris. The flashing is shown with a drip edge is formed by extending the flashing beyond the external surface of the outer wythe and, with the edge being foil lined, manually forming the drip edge. A peel-and-stick embodiment described herein utilizes clear, nondrooling adhesives. Flashing accessories, namely, an end dam, an inside corner and an outside corner are also described.
TL;DR: In this paper, a pre-molded corner flashing member made from polymer material in a single continuous seamless piece is used to conform with a corner of the rough opening, and a membrane flashing portion intersects each of the interior flashing portions along separate exterior corners.
Abstract: A flashing system including a pre-molded corner flashing member made from polymer material in a single continuous seamless piece. The flashing member has interior flashing portions that meet at an interior corner to conform with a corner of the rough opening, and a membrane flashing portion intersecting each of the interior flashing portions along separate exterior corners, the interior and exterior corners intersecting at a common point. The interior corner of the opening may be sealed by placing the molded corner flashing member in the corner and then running a strip of preferably pre-creased sealing tape or other sealing member along the periphery of the wall opening and overlapping a portion of the sealing member on both the interior flashing portion and the membrane flashing portion.
TL;DR: In this paper, a method of using flashing having a counter flashing member and preferably fabricated from one piece of material is described for weather proofing the juncture of a building at the edge of a sloped roof covered with shingles and a vertical wall covered with a masonry veneer.
Abstract: A method of using flashing having a counter flashing member and preferably fabricated from one piece of material is described for weather proofing the juncture of a building at the edge of a sloped roof covered with shingles and a vertical wall covered with a masonry veneer. The flashing is positioned above the surface of the roof by resting it on a fabricated support positioned at the juncture so that the counter flashing member is extending downward to the roof surface overlapping the vertical flashing member of a shingle-based flashing, such as, step flashing protruding from and above the surface of the roof and flush with the support. Construction of the masonry veneer is begun atop the support with a section of the flashing being interposed between the bottom of the masonry wall and the fabricated support after the flashing, including its counter flashing member, has been properly positioned to cover the support and the vertical flashing member protruding from above the surface of the roof, thereby eliminating the need for separately attaching a piece of counter flashing to the masonry veneer after it has been constructed to overlap the protruding vertical flashing member.
TL;DR: In this paper, a flanged counter flashing unit, flashing system and method is described for weather proofing the juncture of a brick wall overlying a vertical parapet wall and the edge of a sloped roof.
Abstract: A flanged counter flashing unit, flashing system and method is described for weather proofing the juncture of a brick wall overlying a vertical parapet wall and the edge of a sloped roof. The one-piece counter flashing unit of the flashing system has a vertical slit into which is securely fitted the low upstanding side of a J-Channel flashing positioned at the juncture and the vertical leaf member of an L-shaped roof flashing that is flush with the outer face of the upstanding low side of the J-Channel flashing, including a flange section of the counter flashing unit that extends laterally from the top edge of the counter flashing apron and partially over the J-Channel and an apron adapted for overlying the vertical leaf member of the L-shaped flashing. The J-Channel flashing, L-shaped flashing and flanged counter flashing are included in the flashing system of the present invention. According to the method of the present invention, when the flashing system is positioned at the juncture, the brick wall is constructed from within the J-channel so that the counter flashing flange is included in the brick wall. This method eliminates the need for a separate method step of attaching counter flashing to the brick wall at an angle to the horizontal plane of the brick wall after its construction by means of a gouge cut across the brick wall for that purpose.
