These web pages contain detailed information concerning the technology, application and development of evacuated insulation systems for use in building. This website was set up and is maintained using funding from the German Federal Ministry of Economics and Technology (BMWi) by resolution of the German Federal Parliament within the framework of EnOB (Research for Energy-Optimized Building), focal point ViBau (vacuum insulation in building).

Vacuum Insulation Panels (VIPs)

A VIP is an insulation product that is five to ten times thinner than conventional insulation materials used in building (e.g. polystyrene, polyurethane, glass or mineral wool) with the same heat transfer coefficient (U-value).
VIPs have been successfully implemented in buildings for several years. They are a space-saving alternative to conventional insulation materials. Two vacuum insulation products received authorization from the building authorities for the first time in July 2007.

Vacuum Insulation Glass (VIG)

VIG is a double glazing with a vacuum between the panes of glass. This means that slim systems less than 10 mm thick can be realized with heat transfer coefficients of U ≈ 0.5 W/(m²K). Triple glazing, used, for instance, in passive houses, achieves a typical U-value of 0.6 - 0.7 W/(m²K) at a thickness of 28 - 44 mm, but is 50 % heavier. VIG with a U-value of ≈ 0,5 W/(m²K) is not yet available on the market. Production techniques for such systems are currently being developed within the framework of a BMWi funded project. The results will be available in 2012.
