BlowerDoor tests

The overall buildings leakage results from the sum of the individual contribution of its components. Quantifying this contribution would be of major importance for building designers that intend to improve building enclosures for airtightness optimization. Typically, building components airtightness is tested in laboratory but several examples...

Stricter requirements, e.g. for thermal insulation and moisture protection, as well as progression in energy-efficient building have led to the development of special building materials and metrological equipment. Over the last two decades, airtightness measurements, frequently also called “BlowerDoor tests”, have become increasingly...
