Abstract
A flashing assembly includes an inner lip that fits within a rough opening. Bonded to the inner lip is an outer flange that covers a portion of a wall around a rough opening. An outer flap is bonded to the outer flange and has an adhesive on its inner surface that is covered with a backing material. Once a window or other structure is installed into the rough opening, the backing material is removed and the cover flap is secured over a nailing flange. In one embodiment of the invention, the flashings are formed as L-shaped sections that may be fitted in virtually any rough opening by varying the amount of overlap on the L-shaped pieces. In an alternative embodiment of the invention, the flashing assemblies are straight sections that may be used alone or in combination with the L-shaped sections.
Claims17
A system for sealing a window within a rough opening in a wall, comprising:
- a number of flashing assemblies that are installed into the rough opening prior to placing the window in the rough opening and that seal the window, each assembly including:
- an inner lip having a raised water dam that fits within the rough opening;
- an integrally formed outer flange extending from the inner lip and covering a portion of the wall that surrounds the rough opening;
- an integrally formed adhesive outer flap that folds back over the outer flange such that the flap seals a nailing flange of a window between the exterior surface of the outer flange and an inside adhesive surface of the outer flap.
A window flashing assembly for sealing a window within a rough opening of a wall, comprising:
- an inner lip that lines an interior surface of the rough opening, the inner lip including a raised water dam that directs moisture toward an exterior of the rough opening;
- an integral outer flange that extends outwardly from the inner lip and covers a portion of the wall that surrounds the rough openings;
- an integral outer flap that is foldable back over a nailing flange of a window placed in the rough opening such that the nailing flange is sealed between the outer flange of the window flashing assembly and the outer flap.
A system for sealing a window in a rough opening in a wall, comprising:
- a number of flashing assemblies, each of which includes:
- an inner lip that fits within the rough opening;
- an integral outer flange that extends from the inner lip and covers a portion of the wall surrounding the rough opening;
- an integral outer flap extending from an outside edge of the outer flange and is foldable back over the outer flange;
- wherein the flashing assemblies may be overlaid at the corners of the rough opening such that the outer flanges of adjacent flashing assemblies can be shingled over each other and the outer flaps of adjacent flashing assemblies can be shingled over each other when the outer flaps are folded back.
A window flashing assembly for sealing a window within a rough opening comprising:
- an inner lip that fits within the inner surface of the rough opening;
- an outer flange integrally formed with the inner lip, which extends from the inner lip and covers a portion of a wall surrounding the rough opening;
- an outer flap integrally formed with the outer flange, which is foldable over a flange of the window to sandwich the window flange between the outer flange of the flashing assembly and the outer flap.
