US Patent 9592529 Weather resistive barrier with drainage surface

Weather resistive barriers and methods of making such are provided. A weather resistive barrier provides a space permitting drainage of liquid water or condensation and for air movement. Applications include where the weather resistive barrier is coupled to a sheathing material and further covered with an exterior building covering, thereby providing space between the sheathing material and the exterior building covering. In this way, the amount of moisture exposure experienced by a structure can be controlled and the structure protected. The extent of water drainage and airflow can be tailored according to particular applications.
