AbstractEfficient insulating systems are the key to the energy efficiency of a building envelope. Vacuum Insulation Panels (VIPs) offer excellent thermal resistance properties that can enhance the energy efficiency of insulating systems, use less space, and provide savings in energy consumption. However, from a Canadian perspective, VIP systems are little known and indeed unused in the building industry. There is a need to investigate the prospect of using VIPs in various components of building envelope. The long-term thermal insulating efficiency of the VIPs depends on its ability to maintain an adequate level of vacuum inside the panel. For design purpose the long-term thermal insulating characteristics of the VIPs needs to be understood and defined. This paper addresses some of the test methods that could accelerate the long term changes in thermal resistance and presents selected results from tests using elevated pressure, relative humidity and temperature on three types of VIPs.
