Wifi St. Pölten

Wifi St. Pölten

The WIFI building in St. Pölten had massive problems with odour nuisances at an existing exhaust air duct. A traditional sealing approach (manual sealing with sealant, tape, clamps, etc.) was not possible due to the restricted access to the ductwork. These restrictions brought Aeroseal into play, and the exhaust air ductwork was sealed in time from the inside out.


Building: Building of the Institute for Business Development (WIFI)
City: St. Pölten/Austria
Date: August 2016
AEROSEAL Partner: Aeroseal Austria GmbH
Executing company: LKM
Target: Elimination of odour nuisances from an exhaust air duct
Preseal leakage: 164,3 l/s @ 300 Pa (269 m²)
Postseal leakage: 5,7 l/s @ 300Pa
Reduction of leakage: 96,6%


After sealing with the Aerosal technology, the exhaust air duct now meets the requirements for an airtightness class D. At the beginning, the ductwork only complied with an airtightness class A. The odour nuisances could be eliminated.
