ABSTRACT:
A hand-tearable barrier laminate includes a reinforcing layer having a first tensile strength. The reinforcing layer is laminated to a flexible cellulosic web. The web has open porosity and a second tensile strength which is less than the first tensile strength. The web is treated with a water-resistant polymeric resin for providing liquid water resistance to the web while permitting water vapor to pass through the web. This hand-tearable barrier laminate can be substituted for polymer foam and microperforated plastic films currently employed by the housing industry, reducing costs.
