Airtightness measurement

Sits.Fits.Airtight

For a building physics flawlessly and energetically optimized building envelope compliance with the requirements for airtightness is indispensable. Other reasons for an air-tight construction are high level of comfort, sound protection, exclusion of pollutants and the scheduled operation of ventilation systems. The measuring method, called the blower door test, indicates a correct or insufficient installation of the airtightness layer. The air exchange rate (n50 value) is measured with a pressure difference between inside and outside of 50 Pascals.

By using a leakage detection system, leaky connections can be detected and repaired timely. We carry out the measurement for you in accordance with the specifications of DIN EN 13829 and DIN EN ISO 9972. Depending on customer request, we will create an audit report or a comprehensive statement
