Quality control of vacuum insulation panels: Methods of measuring gas pressure

Presented here are different methods of measuring gas pressure, suitable for vacuum insulation panels. They are essential for reliable quality control of these products. New methods for measuring gas pressure in vacuum panels enable fast and efficient quality control after production. The gas and water vapour transmission of high barrier films used as vacuum tight envelopes for the panels can now be determined within a reasonable time. The presented methods are also very valuable for the development of new vacuum insulation products.
