Drain assembly including moisture transportation feature
Aspects of the disclosure relate to a drain assembly that incudes first and second plates, moisture inlet and outlet, a flexible sheet disposed between the first and second plates and extending between the moisture inlet and outlet. The flexible sheet is configured to wick moisture. The drain assembly is configured to position in an opening in a building envelope assembly, seal between the moisture inlet and the moisture outlet adjacent the flexible sheet, and transport moisture from the moisture inlet to the moisture outlet to transport moisture from an interior side of an envelope penetrating component positioned within the opening to an exterior side of a water separation plane.
1. A drain assembly comprising:
first and second plates;
a moisture inlet and a moisture outlet spaced from the moisture inlet; and
a flexible sheet disposed between the first and second plates and extending between the moisture inlet and the moisture outlet, the flexible sheet configured to wick moisture;
wherein the drain assembly is formed as an integral piece;
wherein the drain assembly is configured to:
position in an opening in a building envelope assembly;
seal between the moisture inlet and the moisture outlet adjacent the flexible sheet without a separate seal; and
transport moisture from the moisture inlet to the moisture outlet to transport moisture from an interior side of an envelope penetrating component positioned within the opening to an exterior side of a water separation plane.
2. The drain assembly of claim 1 , wherein the drain assembly is configured to:
vapor seal between the moisture inlet and the moisture outlet adjacent the flexible sheet.
3. The drain assembly of claim 1 , wherein the drain assembly is formed of a flexible material.
4. The drain assembly of claim 1 , wherein the flexible sheet includes a capillary structure.
