Membrane refreshed

Abstract Membrane structures made from technical textiles or foils have been part of the built environment for decades. They appear in a wide range of applications, from private homes to public buildings and open spaces. Because membrane materials are exposed to climatic conditions, they are subject to aging and are therefore not supposed to last indefinitely. In contrast, most supporting elements age in a way similar to conventional building materials. As a result, it is often only the membrane skin that requires treatment or replacement after a number of years, enabling the entire structure to begin a “second life.” Membrane structures can be preserved through various approaches, and regular maintenance plays a crucial role in achieving long‐term durability.
