Abstract
A one-piece, watertight flashing having first, second, and third panels joined together by first, second, and third elongated, watertight regions of intersection. The elongated regions of intersection intersect at a watertight common corner. The first and second panels are at a first angle with respect to each other in the first region of intersection, the second and third panels are at a second angle with respect to each other in the second region of intersection, and the first and third panels are at a third angle with respect to each other in the third region of intersection. At least one of the angles is a non-right angle.
Claims21
A one-piece flashing comprising first, second, and third panels of material impervious to water, each of the panels having first and second edges that radiate from a common location on the respective panel, each of said first and second edges of each of the panels extending alongside and being joined watertight to the proximal first or second edge of the panels on each side thereof, the common locations of all of the panels being substantially at a watertight corner, and the panels being angularly displaced from each other with the third panel being displaced from the first panel by an angle greater than 90° and from the second panel by less than 90°.
A pre-formed flashing for preventing water infiltration at the intersection of a planar wall surface and a planar roof surface of a building, the roof surface intersecting the wall surface along a horizontal line of intersection and extending away from the plane of the wall surface at an obtuse angle, said flashing comprising:
- (a) a substantially planar first water-impervious panel that includes a first common location;
- (b) a substantially planar second water-impervious panel that has first and second edges that converge toward a second common location on the second panel;
- (c) a first water-impervious region of intersection joining the first edge of the second panel to the first panel and with the common locations closely adjacent each other, the second panel extending away from the plane of the first panel in a certain direction and at an obtuse angle with respect to the first panel;
- (d) a third water-impervious panel having first and second portions with first and second edges, respectively, that converge toward a third common location:
- (e) a second water-impervious region of intersection joining the first edge of the third panel to the first panel, (f) a third water-impervious region of intersection joining the second edge of the third panel to the second edge of the second panel, a first portion of the third panel adjacent the second water-impervious region of intersection extending away from the first panel at a second angle with respect to the first panel and a second portion of the third panel adjacent the third water-impervious region of intersection extending away from the second panel at a third angle with respect to the second panel, whereby the first, second and third panels and the water-impervious regions joining them together define a common corner impervious to water, whereby the one-piece flashing is impervious to water.
A self-supporting, one-piece, weather-resistant, multi-panel flashing impervious to water and comprising:
- (a) a first panel comprising a first edge and a certain location on the first panel proximal to a point on the first edge;
- (b) a second panel substantially perpendicular to the first panel and comprising first and second edges that converge toward a certain location on the second panel, the first edge of the second panel extending along the first edge of the first panel and being joined watertight to the first panel with the respective certain locations on the second and first panels being adjacent each other;
- (c) a third panel comprising first and second edges converging toward a certain location on the third panel, the first edge of the third panel being adjacent to and joined watertight to the first panel, at least a portion of the third panel adjacent the first edge thereof extending away from the first panel at an included angle greater than 90°, the second edge of the third panel extending generally along a substantial portion of the second edge of the second panel, a substantial portion of the third panel being at an included angle less than 90° to the second panel, and the respective common locations on the first, second, and third panels being proximal to each other and joined together to form a watertight common corner.
