Our main area of expertise is conducting air tightness tests for large buildings using the "Blower Door" method. We perform these tests across Poland and in Central Europe (Czech Republic, Hungary, Slovakia, Sweden).

With a carefully selected equipment base and decades of experience, we undertake air tightness tests ranging from small residential properties to large-scale facilities such as high-storage warehouses or logistics centers exceeding 700,000 m³ in volume. We rely solely on our own knowledge, experience, and skills. We conduct air tightness tests for large buildings using our own equipment and personnel resources – we are not intermediaries but direct service providers. This allows us to offer our clients fast turnaround times. Our tests comply with the PN-EN ISO 9972:2015-10 standard and incorporate requirements from the Passivhaus Institut for passive building certification, as well as for LEED or WELL certifications.


Other services we offer include:

- Advisory services for achieving air tightness and development of guidelines for contractors.
- Ventilation duct air tightness testing according to PN-EN 1507 and PN-EN 12237.
- Thermographic inspections according to PN-EN ISO 6781-1.
