The kitchen exhaust duct of the Swiss traditional restaurant "Paragraph" was causing odour nuisance in the appartments above. Manual sealing efforts were not an option due to limited access to the duct work. Thus, the only possible solution was to seal the duct with MEZ-AEROSEAL.
Building: Restaurant Paragraph
City: Rapperswil, Switzerland
Date: October 2015
AEROSEAL Partner: MEZ-TECHNIK GmbH
Target: Elimination of odour nuisance through improved tightness of duct work
Preseal leakage: 10 l/s
Postseal leakage: 0 l/s
Reduction of leakage: 100%
The rise duct of the kitchen exhaust was cleaned first. This made sealing with MEZ-AEROSEAL a really easy task, since the sealant could adhere to the leakage without problems. The kitchen exhaust duct was sealed 100%. The odour nuisance could be completely eliminated.
