13th International BUILDAIR Symposium, 2-3 June 2023, Hannover, Germany

In Denmark, a manufacturer and dealer of vapor barrier membranes has observed unusual behavior. The membranes were installed in a small house and show that the system can be set up and be tight. What is interesting is that the airleak range changes over time, and becomes approx. twice as leaky over two months, but then the curve also flattens out, and becomes fixed. 
The observation will be presented, and the presentation is an invitation that others might want to do more research into this.
