In recent years, technological advancements coupled with a reliable track record have resulted in exponential growth in the utilization of PVC roofing membranes. PVC membrane is an excellent choice for almost any roofing project that is exposed to harsh conditions including chemicals, fire hazards, punctures, or threat of vandalism. Heritage Metals & Construction can help you select the best option from a variety of thicknesses, widths, colors, and polyester- or fiberglass-reinforcement types for your particular application.

PROVEN PERFORMANCE

For over 50 years, PVC has proven to be a high-performance single-ply roofing membrane. New formulations have improved its integrity, flexibility, and weatherability. By using only the highest-quality raw materials, including antioxidants, UV absorbers, light and heat stabilizers, and critical biocides, PVC’s long-term performance has been significantly enhanced. Having antimicrobials within the PVC formulation means the membrane remains protected for the life of the roofing system. Used in a variety of assemblies, including plaza decks, roof gardens, and solar applications, it also offers excellent resistance to ponding water and is even used to line swimming pools.

CHEMICAL &  FIRE RESISTANCE

One of the most chemical-resistant single-ply membranes, PVC is non-poisonous, and is resistant to alkalis, acids, and many organic solvents which enhances the performance and long-term service life of the roofing system. It has high resistance to oil and grease from restaurants; jet fuels, nitrogen oxides, and deicing chemicals from airports; and various other chemicals and cleaning solutions from factories and laboratories that might get on the roof and cause damage to other membranes. PVC is the most fire-resistant of all roofing membranes, is difficult to ignite, has low heat release, generates less smoke than other materials, and is self-extinguishing in case of a fire. PVC is also resistant to bird droppings, biological organisms, and pollution, providing further protection against premature degradation.

RESISTANT TO VANDALISM AND FOOT TRAFFIC

PVC roofing membranes are strengthened by tenacious, weft-inserted reinforcing fabrics that enhance resistance to the punctures and tears that can be caused by vandalism and routine foot traffic of maintenance personnel. Certain formulations are classified as Type IV – the strongest/highest rating available – according to the ASTM D4434 PVC Standard, while other membranes are only rated as Type III. Accidental puncture warranty coverage is available which will fix punctures on the roof – regardless of who caused the damage – up to a certain number of hours per year.

QUIET, SIMPLE INSTALLATION IN A WIDE RANGE OF TEMPERATURES

PVC membranes are seamed using a hot-air gun to weld the rolled material together and can be installed quickly in a wide range of temperatures, allowing a better chance for good welds and fewer leaks. A large selection of products include low-odor, water-based adhesives that are ideal for projects undertaken while occupants are in the building. Compounded with heat stabilizers, the membrane is heat tolerant while also remaining flexible in temperatures as low as -56°F (-48°C), so it will not split or crack and stands up to repeated exposure to severe climates.

SUSTAINABILITY

PVC is the oldest thermoplastic in the world and the only thermoplastic that is not comprised of 100% fossil fuels. About 57% of PVC is chlorine, which is derived from the salt in salt water and the remainder of the formulation is from natural gas; both are extremely abundant in the world. Yet the presence of chlorine imparts a range of unique technical features in PVC that set it apart from many other polymers. PVC is flame-retardant, non-poisonous, and resistant to alkalis, acids, and many organic solvents. The addition of plasticizers imparts flexibility and elasticity to the material. With salt being the primary raw material, PVC uses comparatively few non-renewable fossil fuels in its production, offering both an environmental and an economic advantage.
