Research on airtightness durability in Norway

Achieving adequate airtightness of a building envelope is crucial for preventing moisture-related damages in cold and humid climate zones, such as in Norway. Leaky joints and perforations in air and vapor barriers are often critical points where damaging air leakages arise. Thus, the durability of products, such as adhesive tapes, is crucial to ensure a proper airtightness and performance of critical building details and overall constructions.
