In accordance with iAts ( The Independent Airtightness Testing Scheme ), the airtightness testing process is conducted according to strict guidelines.
To ensure that the most appropriate time and day are selected to arrive at your site, we will coordinate with you beforehand. We will also confirm with you the number of dwellings that will be tested. A fan, or many fans, will be provided by the engineer.
While the testing is underway, it will be necessary to seal off the dwelling. Generally, the front door is a suitable location to attach the fan.
This will allow all doors inside the property to remain open, allowing the entire building to be pressurised.
The presence of any air leak will become apparent once the building is depressurised.
