Summary:There is a feeling amongst research as well as industry communities that everything that could be achieved in vacuum insulation panels has already been delivered and that there is no need of any fresh research efforts. This lecture will defy this sentiment by demonstrating the challenges that vacuum insulation research has been facing historically but have not been addressed at all. Though low lying fruit, such as low temperature insulation, has been reasonably researched into and commercially being produced worldwide, but challenges such as high density, high cost, dimensional inaccuracies, thermal bridging effect and high temperature vacuum insulation still remain to be tackled. This lecture will list past achievements and discuss pathways to resolve yet unaddressed research questions.
