AGG (Australian Glass Group) is one of Australia’s leading glass processors, operating three production plants across New South Wales, Victoria, and Tasmania.
For more than 30 years, the company has specialized in manufacturing high-performance insulating glass units (IGUs) for window fabricators serving primarily the residential market and light commercial projects.
As building codes evolve and demand for energy-efficient buildings grows, AGG has continuously expanded its IGU capabilities. Today, producing high-performance glass units that meet strict performance requirements is a core part of their offering.
But delivering performance means more than producing visually flawless glass, it requires consistent verification of what is inside the unit.
Argon-Filled Units: Why Fill Rate Matters for Reliable Insulation Performance
The challenge: Proving argon fill performance
For AGG, quality means delivering exactly what their customers expect: reliable IGUs that meet both performance claims and compliance requirements.
“Our customers need to be assured that we make and deliver what they want, when they want it, and to a consistent quality and compliance,” Supply Chain & Quality Coordinator Wiebke Lackas explains.
In Australia, insulating glass units filled with argon must meet strict performance requirements defined in AS 4666. AGG supplies all its IGUs with argon gas fill of 90% or higher, which significantly improves the insulation performance of windows by lowering the U-value.

However, verifying that the intended gas concentration was actually achieved in production was not always straightforward.
During production, IGUs are filled with argon gas inside the press chamber of the production line. While the filling process can be monitored and target percentages can be set, this does not automatically confirm how much gas ends up inside each finished unit.
Without independent verification, manufacturers may lack certainty about the real gas content in sealed units.
The solution: Fast, non-destructive verification
To gain reliable confirmation of gas fill levels, AGG implemented a Sparklike Handheld gas measurement device.
The decision was driven by several practical factors:
- Fast measurements
- Ease of use in production
- Accurate results
- Non-destructive testing
“The ease and speed of use along with its accuracy was ideal. Also, the fact that this test is non-destructive and a large number of units from real jobs can be tested.”
Instead of relying solely on the filling process settings, AGG can now verify the gas content directly in finished IGUs.
Integrating gas measurement into production quality control
AGG uses the Sparklike Handheld device as part of its regular quality assurance process.
Depending on production output, operators test a number of randomly selected finished units during each shift. These units represent different jobs, sizes, and glass types.
By measuring sealed IGUs directly, AGG can quickly confirm whether production is consistently achieving the required gas fill levels.
If a deviation occurs, it can be detected immediately.
The impact: Confidence in production consistency
For AGG, the key benefits of implementing Sparklike are simple but essential:
- Quick and easy verification
- Accurate measurement results
- Assurance of compliance
- Confidence in production quality
Consistency in argon fill levels is particularly important because it directly reflects the reliability of the production process.
“Consistency in fill percentage is important to us – it demonstrates that we are doing it right.” Supply Chain & Quality Coordinator Wiebke Lackas sums up.
By verifying gas fill levels in finished IGUs, AGG ensures that its products not only look high quality but also deliver the insulation performance promised to customers.
