Heatwaves are intensifying, and temperatures are reaching historical records. In fact, July 2024 was the warmest month globally since records began. According to a recent report by the World Meteorological Organization (WMO), there is an 80% chance that the planet’s annual average temperature will temporarily exceed 1.5°C above pre-industrial levels in at least one of the next five years.

In this scenario, where extreme temperatures are becoming increasingly frequent, prioritizing solutions that optimize the energy efficiency of buildings is essential. CoolTop, developed by Eagle Waterproofing, offers an advanced, technically superior solution for roof protection, drastically reducing heat absorption and contributing to efficient thermal management in buildings.

CoolTop is an aliphatic polyurethane resin that, once applied, forms a continuous, flexible white film with a glossy finish that is easy to clean and maintain, suitable for all kinds of exposed roofs. Its main advantage lies in its ability to reflect a high percentage of solar rays (SRI 105), preventing heat absorption by the roof and thus reducing the structural thermal load. CoolTop technology offers several key advantages for architectural and construction projects:

• Increased energy efficiency: By significantly reducing heat transfer to structures, CoolTop reduces cooling demands, leading to lower energy consumption.
• Improved thermal comfort: Provides a cooler and more comfortable indoor environment, even during periods of high solar exposure.
• Enhanced durability: Protects surfaces from environmental stressors, such as UV radiation, salty environments in coastal areas, and temperature fluctuations, thus prolonging the lifespan of waterproofing solutions. Combined with Ultraflex membranes, it is certified for a lifespan exceeding 25 years.

Cost-efficient and sustainable system

The white CoolTop coating does not only optimize energy performance but also provides other benefits in terms of urban sustainability. It helps mitigate the urban heat island effect, improving air quality and general well-being. Moreover, CoolTop is fully compatible with photovoltaic systems, increasing their efficiency and profitability.

“On a well-maintained waterproof membrane, CoolTop can be applied to keep temperatures in check and extend the waterproofing’s lifespan. Let’s not forget that most membranes installed on the roofs of our buildings degrade due to solar exposure, and their replacement or removal at the end of their useful life generates waste and costs that could be avoided with proper protection,” explains Gemma Mogas, Partner and General Manager of Eagle Waterproofing Ibérica, the European subsidiary of Eagle Group.

Wide versatility

CoolTop is ideal as a finish for our Ultraflex waterproof membrane, certified for a lifespan exceeding 25 years, but it doesn’t stop there.

Thanks to its versatility, CoolTop can be applied to a wide range of substrates, such as bituminous membranes, synthetic membranes (PVC, EPDM…), polyurethanes and polyureas, metals, fiber cement, plastics… Its high compatibility with solar energy production systems, including bifacial panels that maximize the capture of both direct and reflected radiation, makes CoolTop an integral and highly efficient solution for energy-optimized roofing projects.
