Pre-molded corner flashing for use with sealing members
a technology of sealing member and pre-molded corner, which is applied in the direction of snow traps, doors/windows, sills/thresholds, etc., can solve the problems of more difficult work of flexible sealing tape, more likely to have problems caused, and significantly more expensive than conventional pre-creased straight sealing tap

Benefits of technology
[0013] In another embodiment of the present invention, a method of installing a window in an opening defined in an exterior wall of a structure includes providing a pair of corner flashing members formed from polymer material. Each corner flashing member includes a pair of generally planar interior flashing portions each presenting a front and an opposing back side, and a generally planar membrane flashing portion presenting a front and an opposing back side. The pair of interior flashing portions intersects along a first corner presenting a first corner axis, the membrane flashing portion intersects one of the pair of interior flashing portions along a second corner presenting a second corner axis, and the membrane flashing portion intersects the other of the pair of interior flashing portions along a third corner presenting a third corner axis so that the first, second, and third corner axes intersect at a common point. The interior flas
Problems solved by technology
The problem with these strip-based approaches is how to best handle the interior corners in the wall opening.
The disadvantage with this approach is that a seam is created at the corner where these two strips meet that can be prone to leaking.
While generally effective, the flexible sealing tape is significantly more expensive than conventional pre-creased straight sealing tape.
The flexible nature of the sealing tape also makes the tape more difficult to work with and therefore more likely to have problems caused by improper installation.

Embodiment Construction
[0021] Referring to FIG. 1, a section of typical frame building construction having a window rough opening defined therein is depicted with portions cut away to show the various components. Wall 10 generally includes frame 12, interior membrane 14, exterior membrane 16, and exterior wall covering 18. Frame 12 generally includes one or more horizontal plates 20 positioned along the top and bottom of wall 10 with a plurality of vertical stud members 22 extending therebetween. Window rough opening 24 is framed at the bottom with a generally horizontal sill 26 and at the top with a generally horizontal header 28. Sill 26 and header 28 along with studs 22 on either side of opening 24 present generally inwardly facing surfaces 29, which intersect at interior corners 29a and define periphery 29b of opening 24. Plates 20 and studs 22 are typically wood, but may also be metal sections, particularly where wall 10 is not load-bearing. Interior membrane 14 is typically one or more layers of gyp...

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.
Description
RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Patent Application No. 60 / 578,247 entitled MOLDED CORNER WINDOW FLASHING FOR USE WITH SEALING TAPE, filed Jun. 9, 2004, and hereby fully incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to exterior-type flashing for static structures, such as buildings and home. More particularly, the present invention relates to an interior corner flashing system for window and door openings in walls. BACKGROUND OF THE INVENTION [0003] The problems with water leaking into building structures are well known. Various types of flashing and sealing arrangements have been developed for different parts of a building structure to address these problems. [0004] Flashing for use in roofing is the most common example. U.S. Pat. Nos. 5,018,333 and 5,913,779 describe folded flashing members for exterior corners of skylights installed in a roof. U.S. Pat. No. 6,681,530 describes a one-...
