  • Certifications: DAkkS & Cofrac Accredited Calibration
  • Specialty: Airtightness Measurement & Leakage Detection

The Importance of Airtightness

The airtightness of a building envelope is critical for energy efficiency and structural longevity. Uncontrolled air leaks lead to significant heat loss, moisture damage, and poor indoor air quality. The BlowerDoor test is a standardized method (ISO 9972) to pressurize or depressurize a building, accurately measuring air leakage and allowing for the precise identification of faults in the construction.

The Minneapolis BlowerDoor System

High-Precision Fans

Powerful, calibrated measuring fans (Standard, MiniFan, MultipleFan) designed for a wide range of building volumes.

Digital Pressure Gauges

Advanced gauges like the DG-1000 provide highly accurate differential pressure and airflow measurements.

Automated Software

Software like TECTITE Express automates the testing process and generates professional reports compliant with ISO standards.

Leakage Detection Tools

A full suite of tools including thermography cameras, anemometers, and fog generators to pinpoint the exact location of air leaks.

Extended Applications

  • Clean Room Validation

    Ensuring the integrity and specified air change rates of controlled environments.
  • Fire Suppression System Testing

    Determining extinguishing gas holding times for fire safety systems (BlowerDoor FireProtection).
  • Ductwork Leakage Testing

    Using the Micro Leakage Meter to test the airtightness of ventilation ducts and components.
