Ultrasonic air leak detection
No more time lost on site: test the quality and airtightness of envelope components as soon as they are installed.
What is ultrasonic leak detection?
Ultrasonic leak detection is a qualitative diagnostic technique for the building envelope, particularly for window installation. An omnidirectional ultrasound generator, usually placed outside, emits a sound picked up by a sensor inside, which the operator moves to locate
precisely the defects around a window, for example. The strength of the signal shows how large the defects are. Components can be tested before the building is weathertight and before the first air permeability tests.
How is the test carried out?
Collecting technical information
Before the site visit, the operator collects the plans, sections and technical details to be tested, to better understand the building and its potential weak points.
Site visit and test
The operator places the emitter outside the component to be tested and first looks for a signal with a wide-cone receiver, then refines the search with a smaller probe for finer leaks.
Writing the inspection report
The operator writes a full inspection report on the details tested, analysing recurring defects: screws through sealing tape, faulty seals or membranes, etc.
Why use ultrasound testing?
Better site scheduling
Ultrasound tests the airtightness of envelope components without waiting for the building to be fully closed.
A fast and detailed diagnosis
Ultrasound gives fast, cost-effective and accurate feedback on the installation of windows, airtight membranes and other components.
Validating the installation of components
Ultrasound validates the installation of specific facade elements (curtain walls, glazed facades, etc.) or airtight membranes without slowing down the site.
Our expertise
Few testing firms offer ultrasonic leak detection. Our years of experience give us full command of the technique, which we make available to our clients.
