US 8,334,223 B2 · Protective drainage wraps

Abstract

A protective drainage wrap includes a mesh and a coating applied to the mesh. The coating is applied to the mesh to form a plurality of interstices, the interstices being configured to facilitate transfer of water vapor therethrough. The mesh includes material extending in a first direction and in a second direction. The material in the first direction includes a polyolefin, polyester, nylon or combinations thereof and has a first thickness. The material in the second direction includes a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about twice the first thickness so as to assist in providing drainage for moisture build-up. The material in the second direction can be yarn. The coating includes a polyolefin, polyester, nylon or combinations thereof. A process for the preparation of the protective drainage wrap is provided.
