After another summer of record-breaking temperatures, it has become clear once again that building roofs are one of the most critical areas in terms of energy efficiency. Beyond leaks, overexposure to sunlight can increase structural temperatures by up to 30°C, leading to higher energy consumption and accelerated material degradation.
According to the United States Environmental Protection Agency (EPA), a roof with a reflective coating can remain between 28°C and 33°C cooler than a conventional one during the summer months.
Given this scenario, Eagle Waterproofing, a company associated with ANAFRIC, is investing in coolroofing solutions such as CoolTop®, a system that acts as a sustainable thermal barrier, reflecting solar radiation and reducing the building’s thermal load. This solution is already being successfully applied in residential, commercial, and industrial projects.
What makes a coolroofing system truly effective?
The effectiveness of a reflective system does not depend solely on its white color. To ensure efficient and long-lasting performance, it must have:
- A Solar Reflectance Index (SRI) greater than 100.
- High resistance to standing water, especially on flat roofs.
- Easy cleaning and maintenance to preserve its reflective properties.
- Advanced chemical properties, suitable for harsh environments such as coastal areas, where saline environments and high solar incidence can affect material performance.
CoolTop® meets all these requirements and has been designed to offer long-term technical protection and energy efficiency, adapting to different substrates and environmental conditions.
Real Data, Real Benefits
Thermal comparisons conducted by the company show that CoolTop® can reduce roof surface temperatures by up to 20°C compared to metal surfaces and up to 40°C compared to dark synthetic membranes such as EPDM.
These results translate into tangible benefits:
- Lower cooling demands and energy consumption.
- Greater indoor comfort.
- Greater durability of existing waterproofing.
- Improved performance of photovoltaic systems.
- Reduction of the building’s environmental impact.
- A durable and versatile solution
CoolTop® is a glossy, white aliphatic polyurethane resin with high mechanical and chemical resistance. When applied, it forms a continuous, flexible film that is resistant to UV rays, saline, acidic, or chlorinated environments, and algae and mold growth. It is also walkable and resistant to stagnant water.
Its formulation is certified for a lifespan of more than 25 years, ensuring long-lasting and efficient protection.
Furthermore, CoolTop® is not only the ideal finish for the Ultraflex system, but also a solution compatible with multiple substrates: synthetic membranes (EPDM, PVC, etc.), asphalt fabrics, polyurethanes and polyureas, metal roofing, or fiber cement. In combination with solar panels, it maximizes performance and improves the building’s overall energy production.
A tool against the heat island effect
In urban environments, CoolTop® helps reduce roof heating and minimize the heat island effect, improving thermal comfort and quality of life, while reducing collective energy demand.
“Applying CoolTop® to the roof allows temperature control and significantly extends the lifespan of the waterproofing system. With proper protection, the generation of waste and unnecessary replacement costs are avoided,” emphasizes Gemma Mogas, General Manager of Eagle Waterproofing Ibérica.
Commitment to sustainability
With CoolTop®, Eagle Waterproofing reaffirms its commitment to energy efficiency and sustainability. This solution adds value to both new construction and renovation projects and responds to the major technical, environmental, and economic challenges currently facing the construction sector.
