Abstract
A building membrane has two release liners that meet at a split seam. One of the release liners has an integral pull tab formed by a fold. The pull tab enables that release liner to be easily pulled from the adhesive on the second surface of the roof membrane. The fold may define a living hinge that causes the pull tab to be biased form a folded position to an extended position when the first release liner that overlaps the second release liner is removed or peeled off of the building membrane.
