Airtightness testing

Envelope airtightness directly affects energy consumption, comfort and the durability of the structure. Using the blower door method we measure the building's actual airtightness and locate air leakage points.

We test during construction, while defects are still easy to fix, and after completion for technical inspection purposes. The result is a measurement report according to EN ISO 9972 with clear remediation recommendations.
