Installation of a backdraft damper / butterfly damper – the butterfly damper prevents cold drafts and odors
Service Description
The butterfly damper, or cooker hood backdraft valve, is a small but critically important part of kitchen ventilation. It effectively prevents cold air, odors, and impurities from re-entering the indoor air through the exhaust duct. At the same time, it improves the energy efficiency of the ventilation and protects the cooker hood from damage caused by external pressure fluctuations. We install the butterfly damper into the cooker hood’s exhaust duct – whether you have mechanical or gravitational ventilation. The service is suitable for both new buildings and older properties. What the butterfly damper installation service includes • Site check-up: We inspect the exhaust duct dimensions and the structure of the cooker hood. • Selection of the right butterfly damper: We choose a backdraft valve that fits the system (usually Ø125 mm or Ø160 mm). • Delivery and installation: We install the valve into the exhaust duct and seal the joint carefully. • Function testing: We check that the valve operates flawlessly when the cooker hood starts. • Cleanup of the work area: We leave your kitchen tidy after the installation.
