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...

To describe the effectiveness of the thermal anemometer device in assisting airtightness testers to evaluate leakage zones, and specific leakages. There are two main aspects: While the building is pressurised to 50Pa use is made of internal doorways to close off each room to make a 'zone', and an airspeed reading is taken...

The information about uncertainly is essential to correct interpretation of any measurement. Therefore, several authors investigated the reproducibility and repeatability of airtightness measurement during the last years. The experiments were carried out in real buildings of different size and in actual climatic conditions which complicates the comparison...

Part of the research project “Evaluation of leakages in airtight layers – Recommendations for action for construction professionals”, was visiting an object, where air leakages in the roof construction were identified as the cause for moisture damage in the roof structure. The latter was not back-ventilated and was characterized...

The purpose of the article is to introduce the condition of airtightness measurement market of large buildings in the Baltic states and in some European countries. There are also considered national building norms of envelope airtightness and measured values. Based on the measurement results of large buildings (more than 4,000 m3 volume according...

European standards or specific programmes rules describe ventilation airflow measurements at terminal devices according to different protocols. Experience shows that these protocols rarely address the assessment of uncertainties. The main goal of the Promevent project was to develop a reference protocol...

Since 2008 in France, all measurement of building envelope airtightness performed according to the EP-regulations have to be performed by a certified operator. This certification includes a yearly follow-up we use to build up a highly detailed database which includes data of about 90,000 airtightness measurements...

Spain is not a country whre airthightness is considered in building process. We still think on our spacial climate conditions (Mediterranean wheather) and still unknown all about thighness, sealing, leakages consecuences, etc. And this is also for residential or industrial buildings. This Spanish BlowerDoor Test Record will bring us the opportunity...

Leakages in the building envelope may cause severe damage to a building and thus inevitably become an issue not only for building physics, but also for the law. In the case of such legal disputes, the different perspectives of scientists and lawyers frequently turn out to be a problem. This is further acerbated by the different levels of...

Windows according to the Passive House Standard 2016 require a ten times more airtight airtightness class (EN 14351) [1] than around 1990. The installation layer of the windows is constantly moving closer into the area of the insulating layer with possibly moisture-sensitive materials. Therefore, joint sealing of construction and connection joints...
