While building airtightness is a key concern in Nearly Zero-Energy Buildings in most European climates, there exists already a wide range of commercially-available products specifically designed to minimize leakage in building envelopes. The objective of this webinar was to give information on the performance and properties of these products based on research including laboratory and field tests. The speakers also provided information on standards already published and under development on this subject.

For several years, multifunctional tapes have increasingly been used for the airtight installation of windows in new buildings or renovation projects. The adhesive tapes are wrapped around the window on three or four sides. After the installation of the window, the tape expands and closes the joints between window and reveal. Their manufacturers sing the praises of these self-expanding joint-sealing tapes made of foam plastic. However, BlowerDoor tests frequently reveal faults. Accordingly, experts vary in their evaluation and discussion of the products.

In timber frame construction in Europe air barrier systems are typically realised at the interior side of the building envelope. Yet in some applications such as renovation projects it can be easier to provide the air barrier layer at the exterior. This way, the air barrier system – typically board materials in which the joints are sealed with tape – is exposed to outdoor weather conditions. The aim of the present article is to investigate the impact severe climatic conditions on the airtightness of typical taped joints.
