Air leaks are often small, hidden and easy to miss, but they can cause real problems. A few gaps around windows, doors, walls, ceilings, service penetrations or an external opening can lead to heat loss, energy waste, poor comfort and failed compliance checks.
Coltraco Ultrasonics provides specialist air tightness testing equipment for teams that need to find and quantify air leaks with greater accuracy. Our ultrasonic technology helps contractors, air testers, facilities managers, engineers and building owners detect leaks without relying only on traditional air pressure testing.
Instead of simply confirming that a building has air leakage, Coltraco’s equipment helps show where the leak is, how significant it is and where remedial work should be focused.

Portascanner® AIRTIGHT is Coltraco’s advanced ultrasonic air tightness testing equipment for finding and quantifying air leaks in buildings, rooms, compartments and controlled spaces.
It uses ultrasound to locate leak paths through gaps, cracks and poorly sealed areas. The system can detect very small leaks and helps teams check the airtightness of spaces before, during or after a blower door, door fan or pulse testing process.
This makes it useful for:
For clients who need repeat testing across a range of sites, Portascanner® AIRTIGHT gives teams a practical way to find issues early, record findings and support better building performance.
Air tightness testing measures how much uncontrolled air passes through the fabric of a building. This is usually referred to as air leakage, air permeability or airtightness testing.
Air leaks can occur through:
A building may look complete, but still lose warm air through small faults in the envelope area. This can reduce energy efficiency, increase energy loss and make the property harder to heat or cool.
Good air tightness helps create a more energy efficient building, supports better comfort and can help ensure compliance with building control requirements. Airtightness testing is key in improving thermal performance and reducing air leakage per hour per square metre of envelope area for both new dwellings and non-dwellings.
Air tightness is commonly tested by creating a pressure difference between the inside and outside of a building, often using a blower door or air pressure testing equipment. This measures overall air leakage through the building envelope.
Ultrasonic air tightness testing works differently. It uses ultrasound to find the exact leak path through gaps, cracks, doors, windows or walls. This helps teams locate the problem quickly, so repairs can be made before formal air testing or compliance checks.
Air leakage is one of the biggest causes of energy inefficiency. If warm air escapes or cold air enters through unsealed gaps, your heating or cooling systems work harder, resulting in higher energy bills and increased carbon output.
By completing a proper air leakage test, you’ll:
If you need an air-tightness certificate to ensure compliance, our qualified air testers will deliver accurate results that align with UK regulations.
Most air leaks appear where materials meet or where services pass through the building fabric.
Common areas include:
A visual check is not always enough. Some gaps are too small to see but still allow air movement. Ultrasonic air tightness testing helps identify these hidden paths, so the team can take precise remedial action.
You need to undergo air-tightness testing at the right stage of construction, usually once the building envelope is complete but before final finishes.
Whether you’re working on smaller buildings or large commercial structures, testing provides the data you need to avoid delays, demonstrate compliance, and identify areas of air leakage before handover.
Building regulations in the UK require new buildings to meet strict air permeability standards. Air leakage testing helps demonstrate your project meets or exceeds these requirements.
Reducing air leakage can significantly lower a building’s energy consumption, supporting both compliance and sustainability goals.
Whether your goal is regulatory sign-off, improved sustainability, or energy cost reduction, our testing services deliver precise, actionable data.
We understand the needs of modern construction and provide ongoing support throughout your compliance journey, from pre-test preparation to final test reports.
