Benefits of technology

[0012]The assembly can include a pre-applied layer of adhesive on the underside of the membrane to adhesively secure the membrane to the sill member and outer sheathing, and/or the assembly can include an elongate wedge or backdam secured to the sill member underneath a rear edge portion of the membrane to provide the membrane with a forward slope from its rear edge toward its front edge. In addition, the assembly can include a window or the like in...

Problems solved by technology

Moisture that infiltrates these areas will likely become trapped within the building structure and over time will cause structural damage such as rotting of windowsills, framing elements, ledgers and jois...

Embodiment Construction

[0022]The present invention is directed to a flexible membrane that can be used, for instance, to waterproof a sill surface of framework of a window opening of a building structure. However, the flexible membrane is not limited to use in window openings and can also be used to promote drainage at other locations within or adjacent an exterior wall and / or roof assembly of a building. Examples include use of the flexible membranes about building openings such as doors or the like, other through-wall openings such as for conduits, pipes, wires and the like, wall corner and wall-to-roof interfaces, and deck ledger boards and joists.

[0023]By way of example, the flexible membrane is applied to the window opening at the sill before the window is installed. After installation of the window and adjacent outer sidewall and trim building materials, the membrane is embedded within the structure and hidden from sight. The flexible membrane can also be utilized to promote drainage behind trim ele...

Abstract

A flashing material for a building structure is provided. The flashing material includes a flexible water-resistive membrane having an upper textured surface with a series of separate, laterally paced-apart, elongate spacers bonded thereto. The elongate spacers can be polymeric filaments that define an air space and drainage paths across the upper surface of the membrane. Preferably, the filaments have a series of depressions formed therein that provide transverse drainage paths across the filaments. Sill, decking and other building structure assemblies and methods of making the flashing material are provided.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 USC §119(e) of U.S. Provisional Patent Application No. 61 / 120,503, filed Dec. 8, 2008.BACKGROUND OF THE INVENTION[0002]The present invention relates to waterproofing a building structure, such as a building opening, a deck ledger or joist, a corner of an exterior wall, a roof-to-wall interface, a through-wall passage, or the like, and more particularly, the present invention relates to a flexible drainage-promoting flashing material and its method of manufacture.[0003]By way of example, water leakage or seepage can occur through the joints of a window and / or window frame, and moisture infiltration within and around a window opening in a wall can be caused by blowing rain, melting snow or ice, and / or condensation of moisture vapor. Similar leakage and / or seepage can also occur via through-wall passages and other building openings, behind deck ledger boards, within a corner of an exterior wall or...
