What Is Air Tightness Testing And What Are The Benefits?
An Air Tightness Test, also commonly known as an Air Leakage Test or an Air Permeability Test, is a test to determine the level of uncontrolled air flow, or air leakage, in a building. Air leakage can occur through gaps, holes and cracks in the fabric of the building, which are not always visible.
Reduced heating bills and a lower carbon footprint
Research shows that up to 50% of all heat loss in buildings can be due to air leakage and uncontrolled ventilation. Even with adequate insulation, air leakage can still be significant source of heat loss, resulting in higher heating bills and an increased carbon footprint.
Even though the Irish climate does not experience extremes in low temperature, we are exposed to to extremes in wind pressure, making Air Tightness Testing central to building energy efficiency. Just a few hours of air sealing with inexpensive sealants, can often reduce air leakage by 50% or more. This can result in a saving of 20% on heating bills.
Increased comfort level and a healthier work and living environment
Air Tightness Testing can help improve the acoustic and environmental comfort of a building. It can also reduce the volume of harmful pollutants and irritants entering a building, particles such as pollen, dust, insulation fibers, mildew and mould, that are typically drawn from under floor boards, the attic or directly from the outside.

Useful Air Tightness Tips
For improved air tightness and reduced heating bills, apply the following measures:
- Seal gaps around windows and doors
- Fill holes in external walls
- Seal gaps where service pipes and cables pass through the building fabric
- Ensuring there is good seal around the boiler flue pipes where they pass through the external wall and ceiling
- Apply draught stripping between the attic hatch and frame
- Seal around the edges of rooms and make good any gaps in the floor around service pipes
