Revestimientos Técnicos Sostenibles (RTS) is an Andalusian materials company that develops and manufactures thin-layer sustainable coatings and insulation for construction, energy retrofitting and demanding industrial/offshore applications, using cork, hollow ceramic and aerogel microspheres to deliver thermal, acoustic and moisture insulation at 1–3 mm thickness. Its product lines include ReveCork, Zeramic Extrem and Metallum, and it sells in more than 20 countries from its production plant in Utrera (Seville). In November 2024 Iberdrola invested in RTS through its Perseo corporate venturing programme after more than three years of joint development on anti-corrosion protection for offshore wind structures; the amount was not disclosed.
