Since 1989, BlowerDoor GmbH has been advocating airtightness of building envelopes. Saving energy, energy efficiency, and sustainability for a viable future have been matters of great concern for us. We also strongly believe in supporting institutions and projects and have been engaged in sponsorship for several years now.
In our newsletter, we regularly report on the associations and projects we support. The newsletter is published and mailed two to four times a year.
