A rainscreen drainage plane is an air gap and the water resistant barrier of a rainscreen. Together they provide a predictable, unobstructed path drainage for liquid moisture to drain from a high point of the wall (where it enters) to a low point of the wall (where it exits) the wall detail.
A variant on masonry veneer is the rainscreen veneer. Rainscreens are ventilated at the top and bottom of the cavity to prevent wind-driven rain from being driven into the building by unbalanced pressure. Such systems are typically encountered in areas where blowing rain is a significant concern.
In order to achieve these objectives, all building enclosure systems must include a solid structure, a drainage plane, an air barrier, a thermal barrier, and may include a vapor barrier. Moisture control (e.g. damp proofing) is essential in all climates, but cold climates and hot-humid climates are especially demanding. [8]
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

The articles rainscreen drainage plane, rainscreen, rainscreen principle, and rainscreen cladding all cover the same subject. Rainscreen cladding was started in 2008, has a good title, has several references, and has four interlanguage links so I propose this be the article title and the others merge into the article rainscreen cladding.
Drainage is the equilibrium soil-to-geosynthetic system that allows for adequate liquid flow without soil loss, within the plane of the geosynthetic over a service lifetime compatible with the application under consideration. Geopipe highlights this function, and also geonets, geocomposites and very thick geotextiles.
