Vacuum insulation panels (VIP) were already developed some time ago for use in appliances such as refrigerators and deep-freezers. Their insulation performance is a factor of five to eight times better than that of conventional insulation. Used in buildings they enable thin, highly insulating constructions to be realized for walls, roofs and floors.
The introduction of such a novel material in the building trade, however, is hampered by many open questions and risks. Hence within the scope of a four-year research project, which was carried out within IEA/ECBCS Annex 39 'HiPTI – High Performance Thermal Insulation', an international research team investigated the fundamentals of vacuum insulation panels and the prerequisites, risks and optimal application of these materials in the building trade. The study was financed by the Federal Office of Energy of Switzerland. On the Swiss side, a working group vip-bau.ch consisted of the Institute of Energy at the FHBB, the EMPA and Dr. Eicher+Pauli AG. In close co-operation with VIP suppliers in Switzerland, Subtask A addressed fundamental questions in connection with the material, whereas Subtask B examined questions regarding the application of VIP in the building trade.
The present Final Report of Subtask B, illustrated with a wide selection of reports from practice, shows how the building trade deals with this new material today, the experience gained and the conclusions drawn there from. As well as presenting recommendations for the practical use of VIP, the report is also able to answer questions regarding the effective insulation values to be expected with today's VIP.
