In Rapperswil at Lake Zurich a residential/commercial/hospital building is currently being built. The very high demands to air tightness were only just missed in this project. The intervention with MEZ-AEROSEAL helped the customer to reach the dictated tightness class in a quick and uncomplicated way. Thus, time-consuming and cost-intensive measures for a subsequent, manual-sealing of the air duct systems weren't necessary.
City: Rapperswil, Switzerland
Date: 18.03 - 20.03.2015
AEROSEAL Partner: MEZ-TECHNIK GmbH

Postseal leakage: 21,7 l/s
Reduction of leakage: 72%
The Merkurhof project includes 436 m2 of vertical and horizontal ducts for supply air and return air on 2 floors. The average sealing time for the 6 injections was 11 minutes. The installed air ducts were already of really good quality in the beginning. With MEZ-AEROSEAL, the ducts now meet the code requirements of tightness class D.
