Flashings for windows and the like

Abstract

A flashing and method for installing a window or other portal in a wall opening is provided. The flashing includes a base member with first and second portions that are angled so that an outer surface of the first portion can be disposed against a sill of the opening and an outer surface of the second portion can be disposed against one of the jambs of the opening. A front face plate of the flashing extends perpendicularly from the first and second portions of the base member, and a plurality of channels in the base member are structured to direct water toward and through the front face plate.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a continuation-in-part of U.S. application Ser. No. 10 / 753,135, filed Jan. 7, 2004, which is hereby incorporated herein in its entirety by reference.FIELD OF THE INVENTION [0002] This invention relates to the installation of windows or other building members and, more particularly, relates to a flashing for directing water and preventing leakage of the water at a window or other portal. BACKGROUND OF THE INVENTION [0003] During a typical installation of a window in a building, a rough opening is first prepared in a wall of the building for receiving the window. The rough opening is defined by two jambs that extend vertically from a head at the top of the rough opening to a sill at the bottom of the opening. A weather resistant barrier material, such as a thin sheet of waterproof paper or plastic can be disposed over the outer surface of the wall, and the barrier material is cut at the rough opening and folded into the...

AI Technical Summary

Benefits of technology

[0009] In addition, a third flashing can be disposed between the first portions of the first and second flashings. The third flashing can include a base member that is disposed between the first portions of the first and second flashings with an outer surface of the base member disposed toward the sill of the opening. A front face plate of the third flashing extends from the base member of the third flashing in a plane generally perpendicular to the base member of the third flashing and generally parallel to the outer surface of the wall, i.e., generally parallel to and between the front face plates of the first and second flashings at the corners of the opening. A plurality of channels are disposed in the inner surface of the base member of the third flashing opposite the outer surface of the base member of the third flashing. The channels in the inner surface are structured to direct water out of the wall and through the front face plate of the third member, e.g., to an inside or outside surface of the wall. Thus, the third flashing can prevent water from contacting the sill of the opening between the first and second flashings. A membrane or other sealing material can be disposed over an interface that is defined between the base members of the first and third flashings and between the base members of the second and third flashings to prevent water from flowing through the interfaces.

Problems solved by technology

The barrier material forms a moisture barrier extending over the outer surface, but due to the cuts in the barrier material does not normally provide a waterproof barrier on the inner surfaces of the rough opening.

However, in some cases, the window can leak water to the sill.

Thus, the water can flow into the wall, i.e., between the inner and outer surfaces of the wall, causing damage to the wall.
