ElvaFlex™ Sealing for Solar Roofs
Protect Your Solar ROI with ElvaFlex™ Roofing
As South African industries rapidly transition to renewable energy, the integrity of the roofing substrate has never been more critical. ElvaFlex™ provides the premier Solar-Ready foundation, specifically engineered to support the long-term mechanical and thermal demands of photovoltaic (PV) installations. Unlike standard roofing materials that may degrade or require replacement mid-way through a solar panel’s lifespan, our KEE-based formulation offers unparalleled UV stability and heat resistance.
By choosing ElvaFlex™, facility managers ensure a high-reflectivity surface that enhances solar efficiency while providing a robust, 30-year watertight platform that eliminates the risk of costly structural leaks beneath your energy investment.

































Engineered to Outlast the Solar Revolution
The true cost of a failing roof under a solar array is the astronomical expense of dismantling panels for repairs. Our ELVAFLEX RP120 systems are exclusively designed to outlive your solar panels:
- 35-Year Life Expectancy: Proven durability that ensures your roof remains maintenance-free for the entire lifecycle of your PV system.
- Maximum Reflectivity: Our white membranes provide high solar reflectance, reducing the ambient temperature on the roof and significantly increasing the energy efficiency and output of your PV panels.
- Unmatched Chemical & UV Resistance: Specifically formulated to withstand the extra thermal stress and chemical exposure common in solar-integrated industrial environments.
Precision Penetration Detailing:
The Haogenplast Standard A solar array introduces hundreds of complex anchoring penetrations. Standard sealants fail under the pressure of solar mounts and extreme African heat. We employ a specialized, multi-layered sealing technique:
- Custom ElvaFlex Cones: We utilize prefabricated cones to perfectly cover omega-shaped profiles and base frames, creating a homogeneous welded seal.
- Hermetic Sealing: We combine hot-air welding with advanced polyurethane-based sealants around screwing rods to ensure an absolute, airtight barrier.
- Dynamic Expansion Handling: Our system moves in sync with your building’s thermal expansions, preventing stress on the mounts and maintaining watertight integrity.
Protecting Your Energy ROI
With a guaranteed 20-year system warranty, Haogenplast provides the only foundation strong enough to secure your renewable energy future. We collaborate directly with your engineers and architects from the design phase to guarantee flawless integration and uninterrupted energy generation.
