Problems solved by technology

One specific challenge in many buildings is sealing recessed windows.
The corners of recessed windows are particularly difficult to flash and seal adequately.
However, both of these flashing systems includes seams and gaps through which water can infiltrate, and both systems rely on piercing fasteners to install the flashing, such as staples, providing further opportunity for water to infiltrate.

Embodiment Construction

[0014]FIG. 1 illustrates a corner flashing member 10 according to the invention. Flashing material 12 has four faces in three planes, 10a, 10a′ (it is noted that 10a and 10a′ are coplanar), 10b and 10c, where the three planes are at right angles to each other in the shape of a recessed corner. The three planes share three common edges 11a, 11b and 11c. The corner flashing member is free of seams or holes through which water could infiltrate behind the flashing. The flashing material is elastic, conformable and flexible such that it can not only fit into the recessed corner of a recessed window, but it may also be extended and wrapped around the exterior wall. The length of the flashing material on either side of the corner is at least about 1 inch, and is typically about 6 inches.

[0015]FIG. 2 illustrates a cross section of the flashing material 12. Flashing material 12 has a topsheet 14, a pressure sensitive adhesive layer 16 on one surface of the top sheet and a release sheet 18 re...

Abstract

The invention pertains to a self-adhesive corner-shaped flashing member for flashing a corner of a recessed window or other opening in a building and a method for making the member. The invention also pertains to a method for flashing recessed corners of recessed windows and the like.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a flashing member for waterproofing corners of recessed windows and other rough openings in buildings such as doorway openings, ductwork passages, and other types of openings that can be found in houses and other building structures.[0003]2. Description of the Prior Art[0004]In building construction, it is important to provide a water-tight seal around any rough openings in exterior walls, including windows and doors. One specific challenge in many buildings is sealing recessed windows. Recessed windows include an outer wall opening that is flush with the exterior of the building, and an inner, recessed framed opening, that lies in a plane behind that of the exterior. Generally, the inner framed opening has a height and width less than that of the outer framed opening. When the window is finally installed, it lies within the inner framed opening.[0005]The corners of recessed windows are particul...
