AIR TIGHTNESS TESTING

Mandatory for all new dwellings; optional for conversions.

We use the latest pulse testing equipment; this is a much quicker way of assessing the dwelling, no blower door needed!

Air Testing (also known as Airtightness Testing; Air Permeability Testing; Air Leakage Testing and Air Pressure Testing) is the recognised method used to determine the total air lost through leaks in a building’s fabric, also know as its envelope. The test measures the amount of air that escapes through gaps or air leakage paths throughout the building envelope. The more airtight a building is, the less energy will be wasted through the leakage of heated air. This both lowers the environmental impact of the building as well as saving the occupant money in their energy bills.

A high Airtightness score can account for up to 50% of heat loss from within a building to the outside. However, it is possible for buildings to be too airtight if adequate ventilation is not specified and installed, this can lead to condensation and black mould growth. Therefore, striking a balance is crucial.
