Conventional Roofing Systems

ElvaFlex vs. Other Methods

Technical Superiority Rooted in Decades of Experience

For over 40 years, Haogenplast has been engineering and deploying advanced, high-performance synthetic roofing systems across global commercial sectors. While conventional materials like traditional bitumen were once the industry standard, modern mega-structures, massive logistics hubs, and solar-integrated roofs now demand a much higher level of engineering precision.

This is where the fundamental engineering difference between standard PVC and ElvaFlex becomes critical: traditional PVC membranes rely on liquid plasticizers, which gradually extract and evaporate under intense solar heat. As a result, the material dries out, loses its flexibility, and cracks within 10 years, leading to costly premature replacements.

In contrast, our flagship ElvaFlex™ formulation utilizes top-tier solid Elvaloy (KEE) polymers by DuPont. Because this solid-based formulation exercises virtually no extractions over its operational lifespan, it never dries out or develops cracks. It retains absolute flexibility and watertight integrity even under the harshest South African sun. This technical superiority allows us to confidently provide a comprehensive 20-year warranty for a system proven to deliver dependable, maintenance-free performance for over 30 years.

ElvaFlex vs. Bitumen (Asphalt): Drastic Weight Reduction

  • Weight & Structural Load: Traditional bitumen adds massive weight to a structure—up to 5.2 kg per square meter. ElvaFlex reduces this by 60%, weighing only 1.6 – 2.1kg/m², , drastically reducing the dead load on your building’s framework.
  • Safety & Installation: Bitumen requires highly dangerous open-flame torches for installation. Our PVC membranes are applied using state-of-the-art hot-air welding, meaning zero open flames and zero fire hazards on your active commercial site.
  • Maintenance & Aesthetics: Bitumen absorbs heat and requires continuous maintenance. ElvaFlex is reflective, aesthetically clean, and virtually maintenance-free for decades.
  • Sustainability & Eco-Safety (Closed-Loop Production): Traditional hot tar and bitumen applications are highly toxic, emitting hazardous, pollutant fumes during installation and leaving behind non-recyclable chemical waste. In stark contrast, ElvaFlex™ is manufactured using an eco-friendly, closed-loop production process where 100% of production scrap is recycled back into the manufacturing cycle, resulting in zero material waste. The final membrane is fully recyclable, and its highly reflective white surface deflects solar heat—slashing facility cooling costs by up to 40% and minimizing your building’s operational carbon footprint.

ElvaFlex vs. Standard TPO/EPDM: Superior Resilience

  • Long-Term Weldability: Standard TPO membranes become highly problematic to repair or weld after just a few years due to environmental degradation. ElvaFlex remains fully weldable for its entire lifespan, making future facility modifications or solar additions effortless.
  • Superior Chemical Resilience: While standard synthetics have limited resistance to oils and industrial pollutants, our KEE/PVC formulation excels in resisting harsh chemicals, grease, and jet fuels, making it the premier choice for demanding industrial zones and airports.
