ABSTRACT:
Hand-tearable barrier laminates are provided which include a reinforcing layer having a first tensile strength laminated to flexible cellulosic web comprising 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 it. Inexpensive web materials can be substituted for polymer foam and microperforated plastic films currently employed by the housing industry.
