Impact of dust build-up on building airtightness durability: preliminary results of the Durabilitair2 project

The DURABILITAIR project, conducted from 2016 to 2019, aimed to assess the durability of air sealing products used in building envelopes. Key findings were presented at the AIVC conferences in 2017 (Nottingham, UK) and 2019 (Ghent, Belgium). This research enhanced understanding of the in-situ characterization of air tightness evolution in homes over time and contributed to developing accelerated aging test protocols under controlled laboratory conditions. 
Built on the previous project, DURABILITAIR2 seeks to deepen knowledge of air tightness evolution, particularly focusing on the implementation and early use of air sealing in newly built single-family homes. This project addresses the French Ministry of Construction's request to further investigate the energy performance of buildings over time.
