Blowtest 3000

The blower door measurement method is a standardized method for checking the air tightness of the building envelope. The n50-value (air exchange rate) indicates the number of times the air is exchanged in the measured building per hour. The limit values are regulated in national standards or in requirements for the promotion of housing, but can also be prescribed by the planner. The blower door measuring method can be used to measure both dwellings and entire buildings.
