Proven Performance PVC vs. Lower Performance PVC
PVC is the oldest thermoplastic single-ply roofing membrane on the market today; since its inception in 1960s Europe, technological advances have improved the product’s performance and service life. As a leading manufacturer of single-ply roofing membrane, Versico Roofing Systems is invested in educating construction professionals about the PVC membranes available in today’s market, and how these membranes compare to each other as well as alternative systems.
PVC roofing membranes have proven to be successful in low- and high-slope applications for more than 50 years; however, some manufacturers are now producing and promoting a lower-cost, lower-performance PVC membranes. These membranes are considered lower-performance products and may not provide the strength and durability that has been traditionally attributed to PVC membranes.
PVC Roofing Systems
Proven-Performance PVC: Versico’s VersiFlex™ PVC membranes have a monolithic formulation above the scrim that ensures long-term weatherability and achieves the maximum amount of protection against the elements. Having a monolithic formulation above the scrim has proven to be effective for more than 50 years.
Lower-Performance PVC: In order to reduce costs, some lower-performance PVC membranes use a two-layer top ply composition in which the full weathering package is only present in the ﬁrst layer of the top ply. Consequently, the effective amount of weathering resistance is reduced.
Proven-Performance PVC: Versico’s proven-performance PVC membranes can be used in a variety of assemblies, including plaza decks, roof gardens, and solar applications.
Lower-Performance PVC: Because lower-performance PVC membranes are not intended for harsh conditions and complicated applications,manufacturers often prohibit their use in plaza decks,vegetated roofs, and solar panel applications.
Protect Your Investment
Ensure that the company providing your PVC membrane approves its use in the harshest environments including plaza decks, roof gardens, and solar applications.
Proven-Performance PVC: Xenon-Arc and long-term heat aging tests show that Versico VersiFlex PVC exceeds the highest industry standards. Versico’s PVC membrane formulation uses only the highest-quality raw materials, including antioxidants, UV absorbers, light and heat stabilizers, and critical biocides, significantly enhancing long-term performance.
Lower-Performance PVC: One of the easiest ways to decrease the cost of a PVC membrane is to reduce the quality and quantity of its weathering and stabilization package. This lowers the material’s cost, but also negatively affects the long-term performance of the roofing system.
Proven-Performance PVC: When you use Versico VersiFlex PVC, you can rest assured that your building will have outstanding warranty protection. Versico’s Total System warranties reflect a commitment and ability to address any warranty issue for up to 30 years. Versico also offers warranties that protect against hail and accidental punctures. Manufacturers of proven-performance PVC membranes have tested and will offer enhanced wind speed warranties for up to 120 mph.
Lower-Performance PVC: Most lower-performance PVC manufacturers offer restricted warranties, typically lasting no longer than 20 years. No Dollar Limit warranties are rarely an option. These manufacturers limit their liability to the original installed cost of the roofing system over the life of the warranty, and most of these manufacturers do not offer warranty options for hail or accidental punctures. Manufacturers of lower-performance PVC membranes may also limit their liability to gale force wind warranties.
