C3 Single-ply Roofing Systems
For mechanically-fastened or ballasted roofs, you can’t find a better roofing, or re-roofing membrane than Cooley C3.
C3 is an advanced formula single-ply membrane that beats its competitors in every category: ease of application, performance and long term cost savings! C3 is remarkably workable. It’s easy to trim and shape, a timesaver when our roof is broken up by pipes, structures, ducts, or air conditioners. Plus, Cooley’s standard extra-wide rolls means C3 installs quicker with fewer seams.
As for performance, our PVC with DuPont “Elvaloy” based compound sets the industry standard for every kind of resistance: water, UV, oil, chemical, salt and other pollutants and contaminants. The system is fully approved for fire resistance by the major code organizations.
Installation is simple. Our hot-air welded seams are easy and foolproof, forming a fused bond along the overlapping rolls as strong as the C3 material itself. Because C3 is so tough, with its high tenacity, low-wick polyester reinforcing scrim, you can choose just the thickness you need and save money on material Cooley also uses a patented aramid fiber reinforced edge for superior strength.
Over 25 years ago, Cooley pioneered the white single-ply membrane. Since then, we’ve steadily improved it. Now you can enjoy the result: Cooley C3, the next generation single-ply roofing.
