ALBA Air Tightness Testing
What is an Air Tightness Test?
Also known as Air Permeability or Air Pressure Testing, Air tightness testing is a key part of sustainable building design. Draughty properties are costly to heat and uncomfortable to live in. With modern insulation materials now performing better than ever, controlling air leakage has become even more important. That’s why air tightness testing is required for all new builds in Scotland.
How the test works
- All intentional openings are closed or sealed following CIBSE23 or ATTMA TSL1 guidelines
- A fan is fitted into a door cloth to depressurise or pressurise the building
- Specialist software measures air flow at different pressure levels
- Results are shown as the airflow rate across the building envelope (m³/(hr·m²) @ 50Pa), with temperature and barometric pressure considered
- Smoke tests can be carried out if required to find leaks
Understanding the Results
- We compare your building’s measured performance against targets set in SAP calculations (homes) or SBEM calculations (commercial buildings)
- If your property fails, we provide clear, practical advice to help you resolve issues—whether it’s too permeable (too draughty) or, increasingly commonly, too airtight
Air Permeability Regulations
- Scotland’s commitment to net zero emissions by 2045, outlined in the Climate Change Act 2019, makes air tightness testing mandatory for all new homes.
Standards are detailed in the Building Standards Technical Handbook, Section 6 (Energy), clause 6.2.5, updated February 2023. - Testing can also be carried out on existing buildings seeking to improve efficiency, reduce heat loss, and lower energy costs.

What Our Customers Say
We’re proud of the relationships we build with our clients. Here’s what homeowners, builders, and architects have to say about working with Wendy and Alba Air Tightness Testing.
“Absolutely brilliant service from Wendy. She helped us through our preliminary air test, identifying areas for improvement and indeed helping us to rectify some of those. We then used Alba Air Tightness Testing again for our certificate test and Wendy was friendly, helpful and efficient. Can't recommend highly enough!”
Simon & Emma Candy
“Delighted with the quick response from Wendy at Alba air tightness testing, explained everything I need to do in preparation as was first time getting air test done. Also I’d say not expensive in today’s terms of getting things done when building a house. Very helpful all-round. Definitely would and will recommend AATT Ltd to anyone looking for this service.”
Colin Soutar
