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 Plus Techincal Data Suitability: Almost any commercial roofing application; sloped, curved & flat Composition: A tri-polymer alloy based on DuPont’s high performance Elvaloy compound Reinforcement: Wick-resistant industrial strength polyester scrim, patented aramid reinforced edge Standard Width*: 1.98 m (78 in.) Standard Thicknesses: 1.2 mm (45 mil), 1.5 mm (60 mil) Colors:  White, Grey, Tan Application: Mechanically-fastened and hot-air welded (can also be ballasted) Approvals: Factory Mutual Class 1: 1-90, (18” on center) 1-105, 1-120, 10150 and UL Listing: Class A & B *3.05 m (120”) available

     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.

Cooley C3 Single-ply PVC with DuPont “Elvaloy” Asphalt Built-up Roof TPO Water Resistance (Standing) Has been proven in applications such as roofing and pond liners for more than 25 years Good for 1-5 years, but poor with age Good initial, but unknown with age Fire Resistance Excellent: is naturally fire resistant due to chlorine content Poor: Asphalt is naturally flammable Fair to poor as a fire retardant, FR package such as magnesium hydroxide must be added at levels close to 50% Wind Uplift Excellent film strength of PVC combined with single layer adherence Fair to good depending on installation Similar to PVC Building Load Light in weight: 1 to 2kg/sq mt (2 to 4 lbs./sq.yd.) Heavy Building Load Requirements 6 to 9 kg /sq. mt (12 to 18 lbs./sq.yd.) Similar weight as PVC Chemical Resistance Excellent due to PVC /Elvaloy properties Poor due to asphalt properties Fair to poor; depending on chemicals eg: oil & fats break down TPO Worker Application Simple single ply hot air welding Multiple layers, propane equipment, 300% more time to install, hazardous vapors Much stiffer than C3 Repair Simple: proven easy to reweld aged exposed membranes Difficult to locate leaks Requires new asphalt rolls Difficult to re-weld exposed material Long term weldability is unknown Cost Savings through Longer Life Quick application, energy savings Requires multiple applications Initial low cost but higher comparable costs after 10 years Low up-front material cost Unknown long term cost
