FREOR, a leader in commercial refrigeration solutions, has enhanced its quality control processes by integrating the Sparklike Laser Portable™ device. This non-destructive technology allows FREOR to accurately measure the insulating gas concentration in their refrigeration equipment’s glass units without compromising the integrity of the units. The portability and precision of the Sparklike Laser Portable™ enable efficient quality assurance at various stages of production, ensuring that FREOR’s products meet the highest standards of energy efficiency and performance.
Insul-Lite Manufacturing, a Canadian producer of high-quality insulating glass units (IGUs), needed a reliable way to verify argon gas fill levels without destructive testing. To meet industry standards and maintain their reputation for quality, they turned to Sparklike Handheld™.
By integrating Sparklike’s 2000th Handheld™ device, Insul-Lite can now quickly and non-invasively measure gas content directly on the production floor, ensuring compliance with IGMAC certification and delivering top-performing, energy-efficient glazing solutions.
Sparklike solutions are widely used across the insulating glass value chain for non-destructive gas fill verification. This includes a broad range of manufacturing and inspection applications:
Insulating glass manufacturers – for production quality control and process optimisation
Window and façade manufacturers – for verifying gas concentration in supplied insulating glass units to ensure final products meet quality specifications
Testing laboratories – for product verification, certification, and compliance testing
Building and quality inspectors – for on-site verification of installed insulating glass units
Commercial refrigeration and display case manufacturers – for ensuring insulation performance and reducing the risk of condensation

Many manufacturers and inspectors measure insulating gas concentration to ensure quality, energy efficiency, and compliance with industry standards. Gas fill level affects U-value and long-term performance, so customers use measurement to verify that IGUs meet specifications throughout production and after installation.
Sparklike solutions are used across the insulating glass value chain, including IGU manufacturers, window and façade producers, testing laboratories, building and quality inspectors, and commercial refrigeration manufacturers. These applications appear in multiple case studies on this page.
Across the customer stories, gas measurement is used to verify product quality, detect deviations early, support compliance efforts, and build confidence in insulating glass performance. For many customers, measurement replaces assumptions with documented proof, improving both internal quality assurance and customer trust.
Yes. Many customers use gas measurement during production to support quality control and process optimisation, while others use it on installed insulating glass units to verify performance after delivery or installation. The customer stories on this page demonstrate both production-line and on-site applications.
By providing precise, non-destructive measurement of gas concentration, companies can detect deviations or under-fills early, optimise production processes, and document quality for standards compliance and customer reassurance.
No. The customer cases cover a wide range of insulating glass types, including standard IGUs, coated units, laminated glass, triple glazing, and specialised applications. This variety shows how gas measurement can be adapted to different product designs and manufacturing requirements.
