Maintaining durability and energy efficiency in insulating glass units (IGUs) remains a critical challenge for the building industry, particularly as environmental factors such as UV exposure and temperature fluctuations accelerate gas leakage. A study by Asphaug, Jelle, Gullbrekken, and Uvsløkk (2016) underscored the risk, revealing that double-glazed sealed units with aluminum spacers showed an average 7% reduction in argon concentration under accelerated aging conditions, significantly increasing building energy demand.
Addressing this challenge, Sparklike has positioned its technology as a cornerstone for non-destructive testing (NDT) in IGU quality assurance. By deploying advanced gas measurement devices, the company enables accurate detection of argon and krypton levels in sealed units, safeguarding thermal performance and ensuring long-term energy savings.
With its portfolio of handheld and laser-based devices, Sparklike provides non-invasive gas analysis for both double- and triple-glazed units. The Sparklike Handheld offers quick verification of argon levels, while the Sparklike Laser Portable uses tunable diode laser absorption spectroscopy (TDLAS) to deliver high-accuracy results without damaging the glass. Independent validation, including an ift Rosenheim test report, confirms the system’s ±2% accuracy under demanding production conditions.
Mobile, versatile, and proven in both factory and field settings, Sparklike devices eliminate the need for destructive laboratory sampling. This enhances durability assessments, supports proactive maintenance, and prevents costly IGU failures. By proving compliance with EN and ASTM standards, the tools also strengthen manufacturers’ reputations for quality and reliability.
The ability to non-destructively verify gas fill levels is transforming IGU lifecycle management. As the study highlighted, IGUs with robust spacer systems and consistent gas retention achieve superior long-term performance. Integrating Sparklike devices into production and maintenance processes ensures early detection of faults, reduced waste, and sustainable construction practices.
For an industry under pressure to meet energy efficiency and climate goals, Sparklike’s NDT-driven approach offers a proactive solution—enabling manufacturers, installers, and quality control teams to prevent gas leakage, optimize insulation, and extend the lifespan of sealed units.
