Mandatory or voluntary building airtightness testing has come gradually into force in many European countries mostly because of the increasing weight of building leakage energy impact on the overall energy performance of low-energy buildings. Therefore, airtightness levels of new buildings have significantly improved in the last decade, but a lot of questions remain regarding the durability of airtightness products. Standards exist to evaluate the durability/ageing of construction products, however there is no standardised protocol to characterise durability in terms of airtightness of product assemblies. The development of such a standard is not evident given the multiplicity of airtightness products.

The objective of this webinar was to share information on protocols developed to test the durability of airtightness products in laboratory conditions. It is the second webinar dealing with durability of airtightness following the one focusing on field measurement held on January 30th, 2020 .

This webinar was organised with the support of TightVent Europe and the Air Infiltration and Ventilation Centre ( Both initiatives are facilitated by INIVE (
