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.
Weep hole. A weep, a weep hole, or a weep-brick is a small opening that allows water to drain from within an assembly. Weeps are located at the bottom of the object to allow for drainage; the weep hole must be sized adequately to overcome surface tension.
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]

Sanitary manholes are sometimes used as vents to prevent the buildup of pressurized sewage gas. [4]
The second of the hole's uses is to keep the window free of fog, condensation and other things that may impact visibility. By allowing warm air to infiltrate in between the two panes, the breather ...
