Abstract
A roof 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 roof membrane.
Claims13
A roof membrane comprising:
- a roof membrane body that is vapor and fluid impermeable to prevent vapor and fluid from penetrating through the roof membrane body when the roof membrane body is applied to a surface on a roof, wherein the roof membrane body has a first end and a second end defining a longitudinal direction therebetween, a first side and a second side defining a transverse direction therebetween, a first surface and a second surface defining a vertical direction therebetween;
- a construction adhesive applied to the second surface of the roof membrane body, wherein the construction adhesive effectuates a near permanent bond between the surface on the roof and the roof membrane body when the roof membrane body is applied to the surface on the roof;
- a first release liner having a first side edge and a second side edge, wherein the width of the first release liner is less than that of the roof membrane body, the first release liner having a first surface and a second surface, wherein the first surface of the first release liner is releasably attached to the construction adhesive on the second surface of the roof membrane body;
- a second release liner having a first side edge and a second side edge, wherein the width of the second release liner is less than that of the roof membrane body, the second release liner having a first surface and a second surface, wherein the first surface of the second release liner is releasably attached to the construction adhesive on the second surface of the roof membrane body;
- a pull tab defined by a longitudinally-aligned fold, wherein the pull tab is integrally formed at the second side edge of the second release liner and the pull tab and the second release liner being formed from a single, continuous piece of material, wherein the pull tab that is integrally formed with the second release liner is adapted to be pulled to release the second release liner from the roof membrane body, wherein the pull tab is substantially rectangular when viewed from below, wherein the pull tab extends longitudinally from the first end to the second end of the roof membrane body and the pull tab terminates at a terminal end, wherein the terminal end of the pull tab is defined by a tab edge that extends longitudinally from the first end of the roof membrane body to the second end of the roof membrane body, wherein a width of the pull tab is measured from the terminal end of the pull tab to the second side edge of the second release liner and the width of the pull tab is in a range from about ½ inch to about 4 inches;
- a split seam defined at an overlap of the first side edge of the first release liner and the second side edge of second release liner, wherein at least a portion of the first release liner overlaps the pull tab;
- and
- wherein the first side edge of the first release liner is aligned directly vertical with the tab edge such that the first side edge of the first release liner and the tab edge are the same distance from the first side of the roof membrane body.
