Vacuum insulation panels are high-performance insulation materials used in buildings, refrigeration, cold chain logistics, and equipment insulation to reduce thermal energy losses. However, their thermal performance can vary between the center and edges of the panel, creating thermal bridges that reduce overall insulation efficiency. The EKO HF-01S heat flux sensor provides a practical method for directly measuring heat transfer through VIP surfaces and quantifying local thermal performance. While infrared thermography can visualize thermal edge effects, heat flux measurement is required to quantify the actual heat loss at specific locations. By attaching HF-01S sensors to selected points on a VIP, engineers can compare heat flux at the center, edge, and intermediate positions. In the application example, the measured heat flux was higher near the panel edge than at the center, demonstrating the ability of HF01S to identify and evaluate thermal bridge effects. HF-01S is also suitable for on-site monitoring of VIP installations due to its thin, compact plate-type design. The sensor can be inserted into narrow gaps between insulation materials, allowing heat flux and U-value evaluation under real installation conditions. These measurements help verify insulation performance, compare VIPs with conventional insulation materials, improve edge design, and support energy-efficiency decisions in building and industrial applications.
