【 摘 要 】

The synthetic material developed by Dupont in 1963 for solid surfaces has been used since its origin for numerous applications. One of the most popular ones in the last decade is as a finishing layer on façades. The first references that contemplated this use on the outside were the Seeko’o hotel in Bordeaux executed in 2007 and the refurbishment of the 7700 m² shell of the Hôtel Ivoire congress centre in Abidjan (Ivory Coast) in 2009. In Spain, the first example of the installation of this material is the rehabilitation of the main building of the La Rotonda de la Playa de San Juan urbanisation in Alicante, designed in 1965 by the architect Juan Guardiola Gaya and rehabilitated in 2010 by Miguel Salvador Landmann. Ten years later, our research is focused on the study of the colour ageing of the acrylic resin and natural mineral sheets on each of its façades, with different orientations and exposure to sea and wind. To this end, it has been studied the solar radiation of the surfaces, the wind exposure of their façades and tests with a tele-spectroradiometer has been carried out. The study makes it possible to quantify the differences in colour in all of them and to state that the combination of wind and radiation is the main atmospheric agent causing the degradation.
