Ventilation Testing
What we do
Air Leakage Testing Ltd undertake air flow measurements of background extraction ventilation for Part F requirements.
Requirements
Ventilation is key in controlling moisture and pollutant levels in any building, if the ventilation is not sufficient it can lead to an unpleasant living environment and in the longer-term problems with the building and/or health issues.
Although extract vents claim a level of air flow based on laboratory testing this does not guarantee they will achieve this in practice due to various issues but most commonly the installation. Therefore, Approved Document F (Ventilation) requires background ventilation to be tested after installation meets the requirements:
