Benefits of technology

[0009]an elongated adhesive layer having a width less than the width of the substrate adhered to one of the major surfaces of the substrate adjacent the first lateral edge of the substrate; and
[0010]a release liner covering the adhesive layer wherein the release liner is scored or perforated a

Problems solved by technology

According to conventional practice in open-stud construction, the space between the water resistive barrier and the flashing at the vertical jambs and head is not sealed, thus creating the possibility of rainwater entering between the WRB and the flashing.
Under excessive wind forces, water that has entered the space behind the WRB can travel beyond the width of the flashing into the wall cavity which may result in moisture damage to the framing members, such as rotting of wood studs and loss of insulation.

Embodiment Construction

[0018]The invention relates to an improved flashing product for use along the vertical jambs, head, and sill of a flanged fenestration unit, such as a window, that integrates the peripheral flange of the fenestration unit with a water resistive barrier installed over the framing members of the building. The use of the improved flashing product prevents the ingress of moisture into the wall cavity surrounding the fenestration unit. It should be appreciated that when the term “window” is used, other types of fenestration units, such as doors, skylights, vents, utility supply boxes, and other items that are made to fit into openings in structures, such as buildings, are contemplated.

[0019]FIG. 1 illustrates a cross-sectional side view of the flashing 10 as one embodiment of the invention. It should be noted that the drawings presented herein are not to scale and are non-limiting.

[0020]The flashing 10 comprises a substrate 12 having an adhesive layer 14 partially covering one surface ne...

Abstract

A self-adhesive flashing for integrating a flanged fenestration unit installed in a rough opening in a wall with a water resistive barrier where the flashing includes an elongated substrate having a pressure-sensitive adhesive layer adhered to at least one side of the substrate along a lateral edge of the substrate and methods for applying the flashing.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to flashing for preventing the ingress of moisture into a wall of a building around an installed window.[0003]2. Description of the Related Art[0004]In “open-stud” building construction, windows and other fenestration products are installed directly into building openings formed by framing members (e.g., wood studs) prior to the installation of water resistive barrier (“WRB”) over the framing members which form the wall cavities. Two types of flashing are known for use in open-stud construction. One type of flashing is “nail-on flashing” formed from a strip of water-impermeable film which is nailed to the wood studs before a window is installed such that, upon window installation, the edge of the flashing is covered by the window flange. A second type of flashing is “self-adhered flashing” formed from a water-impermeable film with a strip of adhesive along the edge for attachment to the win...
