Air Tightness Testing
Q50 provides independent, NSAI‑registered Air Tightness Testing for new builds and deep retrofits across Ireland. Chris and the team are experienced and certified assessors, with a base in Laois, but covering properties across Ireland.
Understanding Air Tightness Testing
Air Tightness Testing (sometimes called a blower door, air pressure or air permeability test) measures the uncontrolled airflow that escapes through gaps and cracks in a building envelope. It is a common requirement when building a new home or retrofitting older Irish homes. By finding and sealing these leaks in the building, you can:
-
Meet Part L of the Building Regulations
-
Lower heating bills and carbon emissions
-
Eliminate cold draughts and condensation risk
Our calibrated equipment produces the official qâ‚…â‚€ result required for BER compliance and SEAI grant applications.
The Air Tightness Testing Process
​​
-
Early‑stage diagnostic visit – Before finishes go on, we pressurise the dwelling at 50 Pa, trace leaks with smoke pens and thermal imaging, and prepare an on‑site briefing.
-
Sealing & snagging – Your contractor seals the identified leakage points with tapes, membranes and grommets.
-
Final certification test – We return to carry out the formal test in line with I.S. EN ISO 9972:2015 and issue an NSAI‑recognised certificate, full report and qâ‚…â‚€ value. This report will be available to you in a timely manner.
