Gulf Coast Supply’s VersaLoc Single-Lock (90°) Panel has just passed two major industry tests — ASTM E1646 for water penetration and ASTM E1680 for air leakage. These tests prove that VersaLoc delivers outstanding protection against leaks and air infiltration when properly installed. In short, this means better performance and long-term reliability for your roofing projects. The single-lock design provides a sleek architectural look and is a more cost-effective option compared to heavier mechanically seamed systems — without sacrificing strength or weather resistance.
If you use VersaLoc panels (or plan to), this bulletin confirms the system’s tested, proven performance and outlines installation details needed to achieve these same results. Read Tech Bulletin now.
