Green-Lock Plus Membrane Adhesive is a high-performance moisture-cured polymer adhesive used to construct cold process roofing systems on single or multiple plies of Garland-approved base sheets and Garland-approved membranes. The result is a high-performance, solvent-free, cold-applied multi-ply modified bitumen roof system with an outstanding life span that functions equally well on flat surfaces and slopes up to 3:12. Green-Lock Plus Membrane Adhesive is easy to apply by squeegee.

With 100% solids, zero VOCs, and no solvents, using Green-Lock Plus ensures a low-odor installation to help minimize disruption during a project and meet sustainability goals for the roof's life. Green-Lock Plus also helps reduce energy spending by providing added UV protection that greatly reduces thermal shock while maintaining internal temperatures. Green-Lock Plus White's non-asphaltic formulation reduces fossil fuels used in a roofing assembly, lowering a building's total carbon footprint.
