Multi-family building Effretikon

Multi-family building Effretikon

In a multi-family building in Effretikon/Switzerland, a tenant felt uncomfortable because of smoking odor in his flat. The tenant of the flat below is a heavy smoker and uses the kitchen exhaust air for smoke extraction. The brick-built air duct from the 1950's had massive initial leakage. The target for Aeroseal was to make the duct airtight, in order to eliminate future odour nuisances.
