Abstract
The roll includes an air and water barrier article, a pressure sensitive adhesive disposed on the first major surface of the barrier article, first and second coating compositions disposed on the opposing second major surface of the barrier article, and a liner having a first major surface in contact with the first coating composition and the second coating composition. The first coating composition has a first peel adhesion to the first major surface of the liner that is lower than a second peel adhesion of the second coating composition to the first major surface of the liner. The pressure sensitive adhesive contacts a second major surface of the liner when wound in the roll, and a peel adhesion between the second major surface of the liner and the pressure sensitive adhesive is less than or equal to the second peel adhesion. There are also provided methods of applying barrier articles, films made using these barrier articles, and building envelopes made using such films.
