30 Years of Minneapolis BlowerDoor

In 1989, Robert Borsch-Laaks imported the first Minneapolis BlowerDoor Measuring Systems to Germany and thus laid the foundation for the success story of the Minneapolis BlowerDoor of now 30 years and in more than 30 European countries.

We would like to extend our sincere gratitude and appreciation to our customers, partners, and friends. Thank you all for 30 great years during which the Minneapolis BlowerDoor has become the leading measuring system for airtightness on the market!
In keeping with the words of Albert Schweitzer, we will continue to do our work promoting airtight building layers with great passion and dedication:

"I am more interested in the future than in the past, because the future is where I intend to live."

30 Applications and Testing Methods

Starting on March 30, 2019 we will be publishing 30 instructive abstracts on various airtightness applications and measuring methods in PDF format on this page, one every week for 30 weeks.

We will explain BlowerDoor Measurements in new buildings and during modernizations, the particularities of airtightness tests in large buildings, different methods of leakage detection, and quality assurance using one-point measurements. We will show a wide range of different building types and constructional damages caused by faulty airtight layers. Further topics include the so-called guard zone test, measurements of building components, airtightness testing of clean rooms, as well as testing of ventilation systems. The list of topics continues with driving rain impermeability of post-and-beam constructions, determining extinction gas holding times, radon measurements, airtightness tests of hollow floors, and many more. We will also provide information on interesting research projects.

"Congratulations and thank you to BlowerDoor GmbH for your 30 years of dedicated work toward our common mission of making buildings more healthy, comfortable, durable, and energy efficient. When we first met, the science of building and ventilating tight buildings was very new and you took on the task of educating people about why it is important and how to do it. As a result of your courses, conferences, technical support, and mentoring there are now thousands of people designing, building, and testing buildings that are much better for their occupants and the environment. Thank you for all you do and for your friendship. I hope to work with you for many years to come."
