RENOLIT ALKORPLAN Bright is basically an enhanced version of the high quality RENOLIT ALKORPLAN roofing membrane. It is an energy efficient and ecological innovation in the world of roofing membranes.

RENOLIT ALKORPLAN Bright is an advanced roofing membrane that stands out due to its enhanced features compared to standard roofing membranes. Here is a breakdown of what makes it unique:

  • High Solar Reflectance:RENOLIT ALKORPLAN Bright is designed with a special pure white coating that allows it to reflect a significant portion of solar rays, thus reducing heat absorption. It has a Solar Reflectance Index (SRI) of 115, which indicates its superior ability to keep buildings cooler by reflecting solar heat.

  • Energy Efficiency: This membrane contributes to energy savings by minimizing the need for air conditioning. Buildings that utilize RENOLIT ALKORPLAN Bright can achieve lower energy demands, which in turn reduces carbon emissions.

  • Ecological Innovation: The membrane is not only functional but also promotes sustainability, addressing environmental concerns like the urban heat island effect. This makes it especially suitable for large buildings such as hospitals, schools, refrigerated warehouses, and data centres that generate significant heat.

  • Durability and Maintenance: RENOLIT ALKORPLAN Bright combines the proven longevity and durability of standard RENOLIT ALKORPLAN membranes with the additional benefits of high reflection, making it easier to keep clean and visually appealing.

In summary, RENOLIT ALKORPLAN Bright offers substantial advantages in terms of energy efficiency, sustainability, and longevity, distinguishing it from traditional roofing membranes that primarily focus on waterproofing without these enhancements. 

RENOLIT ALKORPLAN Bright membranes are particularly suitable for projects aimed at maintaining cooler environments within buildings. Ideal applications include:

  • Hospitals and Schools: These facilities typically require significant air conditioning to ensure comfort and manage heat.

  • Data Centres: Buildings that generate substantial heat and depend on cooling to operate efficiently.

  • Cold Storage Facilities: Projects focused on maintaining low internal temperatures, thereby minimizing heat transfer through the roof.

Overall, these membranes help reduce energy consumption for cooling and mitigate the carbon footprint associated with air conditioning systems.

Yes, and it’s highly recommended. RENOLIT ALKORPLAN Bright is designed to enhance the performance of photovoltaic systems in two measurable ways: 

  • Thermal optimisation: PV panels are most efficient at around 25°C. On darker roofs, temperatures can rise significantly, reducing panel efficiency by approximately 0.5% for every degree above this threshold. The bright white surface of RENOLIT ALKORPLAN Bright helps moderate rooftop temperatures, supporting optimal energy output.

  • Reflective gain: With a solar reflectance (albedo) of 0.8, this membrane reflects a substantial portion of sunlight. This reflected light can be captured by the underside of PV panels, potentially increasing energy yield by 3–4% compared to installations over darker membranes.

In addition to these performance benefits, RENOLIT ALKORPLAN Bright is fully compatible with RENOLIT ALKORPLAN Solar mounting systems, ensuring a secure, watertight, and efficient PV installation.

Roof waterproofing with RENOLIT ALKORPLAN Bright

The Auchan shopping centre in Bordeaux required a roof renovation due to its ageing bituminous waterproofing system, originally installed in 1995 and 2009. The goal was to implement a modern, lightweight and sustainable solution that would enhance the building’s thermal performance without interrupting daily commercial operations.

RENOLIT responded with the installation of the RENOLIT ALKORPLAN Bright membrane, a high solar reflectance (SRI) waterproofing system that reduces structural load, lowers indoor temperatures, and cuts air conditioning use by 15–20%
