Lipoplast verifies argon gas levels to guarantee long-term performance
Lipoplast is a family-owned glass manufacturing company founded in 1994 by Dr. Valeriu Cîrpanu. What began as a small 300-square-meter workshop in Timișoara with six employees has grown into a modern operation with more than 150 specialists and a production facility covering 20,000 square meters.
Today, Lipoplast produces approximately 200,000 insulating glass units (IGUs) and 20,000 windows and doors annually across its locations in Timișoara and Constanța. While the company is one of the market leaders in Romania, its reach extends far beyond the domestic market. Lipoplast supplies demanding architectural projects across Europe, including Belgium, Italy, and Germany, as well as North America.
With such a broad market presence, maintaining reliable product performance is essential.
The challenge: Controlling the invisible component of IGU performance
At Lipoplast, quality control is not a final inspection, it is a continuous process that accompanies every step of production.
From the moment glass is cut, it undergoes measurement and visual inspection. These verification steps continue through grinding, tempering, and final assembly. Each stage is designed to ensure the final product meets strict performance expectations.
Yet one critical element of an insulating glass unit cannot be seen at all.
“The most critical component of an insulating unit, the gas that provides its thermal soul, is also the most invisible.” states Stefan Carpanu, Development Manager of Lipoplast
Argon gas impacts the thermal insulation performance of IGUs, making it essential for meeting energy efficiency standards in international markets. But without measurement, manufacturers cannot fully verify the actual gas concentration inside a sealed unit.
Recognizing this challenge, Lipoplast decided to introduce gas measurement into its quality control process.

The solution: Verifying gas fill with Sparklike Laser Portable
To ensure full transparency and reliable data, Lipoplast implemented the Sparklike Laser Portable as part of its production quality control.
Gas measurement now occurs directly after the sealing process, while the unit is still in the production hall. Each measurement verifies that the argon concentration meets the required standards before the unit proceeds further in the workflow.
“It is a brief but vital pause in the production flow that confirms the integrity of the seal and the long-term efficacy of the fill.”
By using a fast, non-destructive measurement method, Lipoplast can verify gas levels without damaging the finished unit or interrupting production.
Detecting hidden risks before products leave the factory
Beyond simple verification, gas measurement has become an important diagnostic tool within Lipoplast’s operations.
Monitoring argon levels allows the team to identify potential production issues early. For example, a deviation in gas concentration can indicate that equipment requires recalibration or that a sealing process has been compromised.
These issues might otherwise remain unnoticed until the product is already installed in a building.
“By monitoring these levels, we can instantly detect if a piece of machinery has drifted out of calibration or if a seal has been compromised by a subtle technological hiccup.”
By identifying these issues early, Lipoplast can correct them immediately, preventing costly post-installation problems.

The impact: Strengthening customer trust
For Lipoplast, the most important result of gas measurement is confidence both internally and for their customers.
The insulation performance of an IGU depends on the gas inside the unit. Verifying the gas concentration ensures that the product will perform as promised over the long term.
“The primary dividend is trust, the currency of any long-term partnership.”
By confirming the argon concentration in every tested unit, Lipoplast can demonstrate that the invisible component of their product has been executed correctly.

Looking ahead: Quality depends on both technology and people
While advanced measurement tools provide valuable data, Lipoplast also emphasizes the human side of quality control.
“The human element remains the most mercurial factor.”
Maintaining high standards requires not only precise equipment but also a strong culture of attention to detail among operators.
For manufacturers considering gas measurement for the first time, Lipoplast’s advice is straightforward:
“You cannot manage what you do not measure.”
Verifying gas content provides clear benefits from higher product quality to reduced risk of post-sales issues, making it a practical step for manufacturers aiming to strengthen their quality assurance processes.
