This is a Blower Door setup that we utilise to conduct air tests on new and existing dwellings.
The fan is used to create a difference in pressure between the interior and exterior of the building.
We are then able to measure the leakage taking place through the buildings construction.
The Building Regulations part L require this type of test to assist in improving the environmental impact of new buildings.
Testing is conducted in accordance with approved procedures and BS EN 13829:2001.
