Air classification - Import export

The airtightness of outside windows and doors is an important criterion for achieving an airtight building envelope. The Window and Door Measurement System developed by BlowerDoor GmbH allows you to determine the joint permeability of building components in a simple and accurate way. On the basis of the measurement results windows and doors can be classified in accordance with EN 12207 (windows and doors, air permeability-classification).
