FALLSINGTON, Pa. — The Griff Network has been awarded U.S. Patent No. 12,662,819 for its innovative Grip N Strip™ technology, a breakthrough split-release liner designed to make self-adhered roofing membranes faster, easier, and more efficient to install.

The newly patented technology introduces an integrally formed folded pull tab within a split-release liner, allowing installers to quickly locate, grip, and remove the second release liner without the frustration commonly associated with traditional split-liner systems. By eliminating the need for additional pull strips or separate components, Grip N Strip™ simplifies manufacturing while delivering a superior installation experience in the field.

The patent covers a unique release liner configuration that incorporates a folded pull tab into the liner itself, improving accessibility and reducing the likelihood of liner tearing or difficulty removing it during installation.

"Grip N Strip™ was developed with one goal in mind—to make installation easier for contractors," said Alex Phinn, company President. "By integrating the pull tab directly into the release liner, we've created a solution that helps installers work faster, reduces frustration on the jobsite, and improves the overall application process."

Traditional split release liners can be difficult to separate, particularly when installers are wearing gloves or working in demanding outdoor conditions. Grip N Strip™ addresses this challenge by incorporating a folded pull tab that naturally presents itself for easy gripping after the first liner section is removed. The design enables installers to remove the second liner quickly while maintaining accurate membrane placement.

In addition to improving installation, the patented design streamlines manufacturing by eliminating the need for separate pull strips or added components traditionally used to facilitate release liner removal. The result is an elegant, cost-effective solution that benefits both manufacturers and contractors.

Although initially developed for self-adhered roofing membranes, the patented Grip N Strip™ technology has broad potential across numerous pressure-sensitive adhesive applications, including waterproofing membranes, flashing products, tapes, building envelope materials, vehicle wraps, graphics, labels, and other adhesive-backed products.

In addition to the manufactured membranes, the patented release liner folding process is available for licensing.

This patent strengthens The Griff Network's commitment to developing innovative products and technologies that solve real-world installation challenges and deliver greater value to customers across the building products industry.
