Vacuum insulation panels : study on VIP-components and panels for service life prediction of VIP in buildings applications (subtask A)

Abstract

This comprehensive paper takes a look at the properties of vacuum insulation panels (VIP) and was presented as a contribution to the IEA's ECBCS (Energy Conservation in Buildings and Community Systems) Annex 39. The various institutions in Switzerland, Germany, Canada, France, Sweden and the Netherlands participating in the task and their activities are listed. The paper describes the concept of vacuum insulation for buildings and examines the physics involved and core materials that can be used. The physical, mechanical and thermal properties of the core materials are examined and the requirements placed on the envelope of the panels are looked at. Tests made on materials as well as on the complete vacuum insulation panels are described in detail. The results obtained are presented and reviewed. Service-life and quality assurance aspects are also discussed. A comprehensive appendix completes the report.
