BSD-105: Understanding Drainage Planeslast updated 2008/08/20 |
|
Controlling rain is the single most important factor in the design and construction of durable buildings and in the control of mold.
Drainage planes are used in the design and construction of building enclosures to control rain.
All exterior claddings pass some rainwater. Siding leaks, brick leaks, stucco leaks, stone leaks, etc. As such, some control of this penetrating rainwater is required. In most walls, this penetrating rainwater is controlled by the drainage plane that directs the penetrating water downwards and outwards.
