An Integrated System for High-Performance Sustainable Roofing: Combining RENOLIT ALKORPLAN Bright and Solar

Together, they form a high-performance system that turns a building's roof into a dynamic asset, perfectly blending environmental consciousness with modern, functional design.

Part 1: The Cool Core – RENOLIT ALKORPLAN Bright

The foundation of this powerful duo is the RENOLIT ALKORPLAN Bright membrane, a market-leading "cool roof" solution.

• Maximum Reflectivity for Passive Cooling: With its brilliant white surface and a Solar Reflectance Index (SRI) of 115, RENOLIT ALKORPLAN Bright excels at reflecting solar radiation away from the building. This drastically reduces heat absorption, which can lower the roof's surface temperature by up to 30°C compared to traditional dark-colored roofs.
• Significant Energy Savings: By keeping the building cooler, the demand on air conditioning systems is substantially reduced. This leads to lower energy consumption, resulting in direct savings on operational costs and a smaller carbon footprint for the building.
• Improved Indoor Comfort: A cooler roof contributes to a more stable and comfortable indoor climate, especially during hot summer months, enhancing the well-being of the building's occupants.

Part 2: The Power Generator – RENOLIT ALKORPLAN Solar

The second component of the system, RENOLIT ALKORPLAN Solar, provides the ideal platform for active energy generation.

• Penetration-Free Installation: This system utilizes a specially developed, lightweight extruded profile with an aluminium insert. This profile is not mechanically fastened but is hot-air welded directly onto the RENOLIT ALKORPLAN waterproofing membrane. This innovative method means there are zero perforations in the waterproofing layer, completely eliminating the risk of leaks and ensuring the long-term integrity of the roof.
• Lightweight and Secure: The system is incredibly lightweight, adding minimal load to the roof structure, which makes it suitable for a wide range of buildings, including those with limited load-bearing capacity. Despite its low weight, it is exceptionally strong and certified to withstand wind loads of up to 200 km/h.
• Direct Energy Generation: It provides a secure and durable base for mounting standard photovoltaic modules, turning the entire roof surface into a clean power plant.

The Synergistic Effect: A Perfect Partnership

When RENOLIT ALKORPLAN Bright and RENOLIT ALKORPLAN Solar are used together, their individual benefits are amplified.

• Increased PV Efficiency: Photovoltaic panels perform more efficiently at cooler temperatures. By installing the RENOLIT ALKORPLAN Solar system on top of a RENOLIT ALKORPLAN Bright membrane, the cooler roof surface helps to keep the solar panels from overheating. This can lead to a higher energy yield and improved performance from your PV system over its lifetime.
• Dual-Action Sustainability: You create a roof that works for you in two ways: it passively saves energy by reducing cooling needs, and it actively generates clean energy for the building's use. This comprehensive approach maximizes the roof's contribution to the building's sustainability and financial goals, delivering an exceptional return on investment.
