The Vacuum Insulation Panel Association (VIPA International) is a global trade association representing the interests of manufacturers of vacuum insulation panels as well as supply chain. The mission of the association is to act as the global voice of the vacuum insulation panel industry, promote quality and raise awareness of the potential to save space and energy costs.

  • Compressive strength of vacuum insulation panels according to EN 826: difficulties with the measurement results for VIPs and possible solutions
    Description of the project:
    Results of compressive strength according to EN 826 of VIPs without any facings (e.g. EPS, PU, etc.) are difficult to evaluate. The main reason is the absence of a linear range in the stress-strain graph, caused by warping of the panel, surface joints and the general behaviour of an inhomogeneous product under load. The consequence of this is that the values for the compressive strength for products on the market are highly depending on the skills of the testing laboratory and show a rather high range of diversity. This project will describe possible approaches to eliminate the fortuity and to increase the reproducibility for the compressive strength measurement on VIPs.
  • Calibration of the lift-off technique for measuring the internal pressure of fumed silica VIPs and determination of boundary conditions for the lift-off measurements and processing of measurement raw data
    Description of the project: 
    The foil lift-off technique is the most commonly used method to determine the internal pressure of VIPs during and after the production process. It is used for more than a decade now without any evidence or comparison to a direct and calibrated measurement method. Besides, boundary conditions for the measurement of the internal pressure according to the lift-off technique are not fixed in a standard or in scientific articles.
