United States Environmental Protection Agency (EPA)<\/a>, a roof treated with reflective coating can remain between 28\u202f\u00b0C and 33\u202f\u00b0C cooler than a conventional roof during the summer months.<\/p>\n\nFaced with this scenario, more and more professionals are turning to coolroofing solutions like CoolTop\u00ae<\/strong>, developed by Eagle Waterproofing<\/strong>. CoolTop\u00ae<\/strong> acts as a sustainable thermal barrier, reflecting solar radiation and reducing the building\u2019s thermal load. It is already being successfully implemented in residential, commercial, and industrial projects of all kinds.<\/p>\n\nWhat makes a coolroofing system truly effective?<\/h3>\n\n
Solar reflectance depends on more than just a white finish. To ensure efficient and long-lasting performance, a system must offer:<\/p>\n\n
\n- A Solar Reflectance Index (SRI) higher than 100.<\/li>\n\n\n\n
- High resistance to ponding water, especially on flat roofs.<\/li>\n\n\n\n
- Easy cleaning and maintenance to preserve reflective properties.<\/li>\n\n\n\n
- Advanced chemical resistance, essential in harsh environments such as coastal areas, where salt and high sun exposure may affect performance.<\/li>\n<\/ul>\n\n
CoolTop\u00ae<\/em><\/strong> meets all these requirements, has been formulated to deliver long-term technical protection and energy efficiency, and is adaptable to a wide range of substrates and climate conditions.<\/p>\n\nReal data, real benefits<\/h3>\n\n
Thermal comparisons have shown that CoolTop\u00ae<\/em> <\/strong>can reduce rooftop surface temperatures by up to 20\u202f\u00b0C compared to metal surfaces, and up to 40\u202f\u00b0C compared to dark synthetic membranes like EPDM.<\/p>\n\nThese results translate into:<\/strong><\/p>\n\n\n- Lower cooling demand<\/strong> and reduced energy use.<\/li>\n\n\n\n
- Improved indoor<\/strong> comfort.<\/li>\n\n\n\n
- Extended lifespan<\/strong> of existing waterproofing.<\/li>\n\n\n\n
- Increased photovoltaic<\/strong> performance.<\/li>\n\n\n\n
- Reduced environmental<\/strong> impact of the building.<\/li>\n<\/ul>\n\n
A durable and efficient solution<\/h3>\n\n
CoolTop\u00ae<\/em><\/strong> is a white, glossy aliphatic polyurethane resin with excellent mechanical and chemical resistance. Once applied, it forms a continuous, flexible film resistant to UV rays, salt, acids, chlorinated water, and the growth of algae or mold. It is walkable and resistant to ponding water.<\/p>\n\nIts formulation is certified for a lifespan of over 25 years, ensuring long-lasting and effective protection. <\/p>\n\n
More than just a finishing layer for the Ultraflex system, CoolTop\u00ae is a versatile solution compatible with a wide variety of substrates and systems: synthetic membranes (EPDM, PVC…), bituminous felts, polyurethanes and polyureas, metal and fiber cement roofs, among others. It also enhances performance when combined with sustainable systems such as solar panels, improving overall energy production of the building.<\/p>\n\n
A powerful tool against the urban heat island effect<\/h3>\n\n
In urban environments, CoolTop\u00ae<\/em> <\/strong>helps reduce rooftop heat and mitigate the heat island effect, improving thermal comfort and quality of life, while lowering collective energy demand.\u201cSobre una membrana en buen estado, aplicar CoolTop\u00ae permite controlar la temperatura y alargar significativamente la vida \u00fatil del sistema de impermeabilizaci\u00f3n. Con una protecci\u00f3n adecuada, se evita la generaci\u00f3n de residuos y los costes innecesarios de sustituci\u00f3n\u201d,<\/em> afirma Gemma Mogas, Directora General de Eagle Waterproofing Ib\u00e9rica.<\/p>\n\n
