Abstract

A protective drainage wrap comprises a first portion, a second portion and a solid sheet portion. The first portion comprises cross-woven or cross-laminate material in the machine direction and in the transverse direction. The material in the machine direction comprises a polyolefin, polyester, nylon or combinations thereof and has a first thickness The material in the transverse direction comprises a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about 2 times greater than the first thickness so as to assist in providing drainage for moisture build-up The second portion is a coating comprising a polyolefin, polyester, nylon or combinations thereof The first and second portions are located adjacent to each other The solid sheet portion comprises a polyolefin, polyester, nylon or combinations thereof The solid sheet portion is attached to at least one of the first portion and the second portion.

Claims (31)
