EDL Glass is a Ukrainian manufacturer of high-quality insulating glass units and architectural glass solutions, supplying products for residential, commercial, and façade projects. Working closely with window and façade manufacturers, EDL Glass has built its reputation on reliable, energy-efficient glazing — backed by continuous investment in modern production technology and quality assurance.
To take that quality assurance a step further, EDL Glass has now installed the Sparklike Laser Integrated™, bringing continuous, automatic inline gas concentration measurement directly into its production line.
Quality Control Is Built Into Every Stage of Production
At EDL Glass, quality control isn’t a single checkpoint at the end of the line — it runs through every stage of production. Raw materials, production parameters, and finished products are all monitored to make sure each insulating glass unit meets both internal standards and customer requirements. As Violeta, EDL Glass, explains, this is a matter of philosophy as much as process:
“For us, quality is not just a final inspection — it is an integrated part of the manufacturing process that helps us deliver consistent and reliable products.”

Sample-Based Testing Only Told Part of the Story
Before installing Laser Integrated, EDL Glass relied on sample-based gas concentration measurements. That approach provided useful information, but it only ever represented a small portion of total production — sampling couldn’t give the company continuous visibility into the gas filling process or let it react immediately to deviations.

Continuous Inline Measurement Without Interrupting Production
As production continued to develop, EDL Glass wanted to strengthen its quality assurance further by introducing continuous inline gas concentration measurement. Sparklike Laser Integrated was chosen specifically because it enables automatic monitoring directly on the production line, without interrupting manufacturing — helping the company verify that its gas filling process stays stable and consistent throughout production.
We have also Sparklike Laser Components for customers who want to build their own mechanical movement and line integration solution.
A Smooth Installation and a Positive First Impression
The implementation process has gone smoothly, and Violeta describes the cooperation with the Sparklike team as very positive. Although the system has only recently been installed, early signs are promising:
“Our first impression is that it integrates well into our production line and provides valuable real-time information without slowing down production.”

Early Days, but Already Greater Confidence in Process Consistency
With the installation still recent, EDL Glass is only in the early stages of evaluating the long-term benefits. Even so, the ability to monitor gas concentration continuously rather than relying on periodic sampling is already appreciated. It gives the team greater confidence in process consistency and lets them identify potential process variations much earlier.

Looking Ahead: Less Manual Sampling, More Process Optimization
Looking further ahead, EDL Glass expects Laser Integrated to improve production stability, increase confidence in the quality of every insulating glass unit, and support its continuous improvement efforts. Also, it reduces the need for manual sampling and provides valuable data to optimize the gas filling process over time.
EDL Glass’s Advice to Other Manufacturers
Asked what advice she’d give other insulating glass manufacturers weighing up inline gas measurement, Violeta was direct:
“Continuous inline measurement provides a much more complete picture of production performance than traditional sampling alone. For manufacturers focused on consistent quality, process transparency, and continuous improvement, investing in inline gas measurement is a logical step forward.”

Continuous, Automatic Gas Concentration Monitoring
The Sparklike Laser Integrated™ brings non-destructive gas concentration measurement directly into the production line, giving IGU manufacturers:
- Automatic, continuous monitoring of every unit — not just a sample
- Real-time visibility into gas filling process stability
- Earlier detection of process deviations, before they become recurring issues
- Reduced reliance on manual sampling, freeing up resources for other quality checks
- Production data that supports long-term process optimization
