Drainable sheathing membrane for exterior wall assembly water management system
First Claim
1. An exterior finishing system for a building for a system comprising:
- a weather resistive membrane having an inner and an outer surface;
an exterior cladding having an inner surface and an outer surface, said inner surface of said exterior cladding disposed adjacent said outer surface of said weather resistive membrane; and
means for managing water between said outer surface of said weather resistive membrane and said inner surface of said exterior cladding, said means for managing water including a non-integral separate raised media on said outer surface of said weather resistive membrane, said non-integral separate raised media forming a vertical drainage medium.

Abstract
An exterior wall assembly water management system that includes flashing, a drainable weather-resistive membrane, exterior cladding, a basecoat and an exterior finish. The basecoat and the exterior stucco finish are applied to the outer surface of the exterior cladding, or in the alternative to an insulation layer. The disclosed water managed exterior system efficiently directs any penetrating water to weeps, or the like, by providing a water drainage medium between the weather-resistive membrane and the exterior cladding. The water drainage medium is embossed upon the outer surface of the weather-resistive membrane, creating a drainage space between the membrane and the cladding. The unwanted water drains downwards via the drainage space, is caught at the base of the wall by the flashing, and is further drained outside of the wall cladding.
