A coat of reflective white paint with a top coat of Kynar Aquatec® emulsion provides an environmentally friendly and economical alternative to installing air conditioning, now backed by French authorities.
More roofs on large shopping centers and logistics warehouses, particularly in Europe, are adopting cool roofing to bring the temperature of buildings down during periods of warm weather. “In 2022, 400,000 m2 of additional roofs will be covered in France by our partner Cool Roof France”, announces Bertrand Dinelli, High‑Performance Polymer European Market Manager at Arkema. Approximately 15% on the energy bill of buildings can be saved, thanks to the combination of a white aqueous paint and a transparent anti‑UV overcoat of Kynar Aquatec® resin, which increases its ability to reflect solar radiation and protects it from mold and dirt for nearly 20 years. “Our coating also enables the roof to self‑clean when it rains, much like an oilcloth, while providing a seal that prevents the release over time of residues from the undercoat”, emphasizes Bertrand Dinelli.
Government recognition This solution has been approved since 2021 by the ATEE (French Energy Environment Technical Association), the body that manages energy saving certificates in France: a major step forward, which will enable developers to benefit from government grants to switch to cool roofs. This recognition could also be awarded in other European countries, such as Spain and Italy. Moreover, Arkema’s Encor® Flex acrylic emulsion, sold in the United States for roof coatings, is an undercoat that is perfectly tailored to use with Kynar Aquatec® emulsion.
