The glass industry is evolving to align with sustainable practices, and insulating glass units (IGUs) are central to this shift. A study called in situ detection of product age and argon concentration as measure of the re-use potential of insulating glass units in buildings published in Glass Structures & Engineering highlighted how measuring product age and argon concentration can determine the reuse potential of IGUs. This innovation is a critical step toward reducing environmental impact by promoting high-level circular use of glass materials. Sparklike is happy to be partnering in this study by providing the argon testing equipment.
The Challenge: Sustainability in the Glass Industry
IGUs are essential for energy-efficient buildings, reducing thermal transmittance and improving insulation. However, their production generates significant greenhouse gas emissions and depletes natural resources. Recycling and reusing IGUs can mitigate these effects, but it requires precise assessment of their condition and performance, especially for re-use strategies. Enter Sparklike Laser Portable™, a solution for non-invasive argon testing for quality assessment.
The Role of Argon Concentration in Circular Use
Argon gas fills contribute to improved insulation of IGUs by lowering thermal conductivity. Over time, argon levels can decrease, impacting energy efficiency and potentially signaling issues with seal integrity. Measuring argon concentration provides insight into the IGU's remaining lifespan and suitability for reuse, whether as a complete unit, reprocessed float glass, or glass cullets.
Sparklike Laser Portable: Enabling IGU Reuse with Non-Invasive Argon Measurement
The Sparklike Laser Portable employs tunable diode laser absorption spectroscopy (TDLAS) to non-invasively measure argon and krypton levels in IGUs. Unlike traditional methods requiring destructive sampling or limited by environmental conditions, this device offers reliable in situ measurements, even on installed IGUs in buildings.
