SORDO-B is available in a RE:3 version. A RE:3 product is an alternative to our conventional products, systems and services, an alternative which is reduced, reused or revitalised. We ensure a notably lower level of embodied carbon, built-in CO2, and let these solutions wear our RE:3 symbol. Read more about RE:3 here.
