Living in the city, working just around the corner, insulatingLiving in the city, working just around the corner, insulatingwith vacuum panels: this is the triad of the future.After all, the population in many large cities has been explodingfor years. At the same time, space there is verylimited, so that every square meter of residential andcommercial area counts – for every individual, as well asfor society as a whole.
The Grand Tower Frankfurt is a prestigious object that impressivelyThe Grand Tower Frankfurt is a prestigious object that impressivelyreflects this fact – it is to be the highest residential buildingin Germany once finished. The skyscraper will soon towerover the heart of the banking metropolis at the edge of theEuropean quarter with its 172 meters and 401 apartments. It isinsulated with vacuum insulation panels (VIPs) by va Q tec – inthe sections of the façade where supply shafts narrow downthe available space considerably. „It’s only a wall strip of 1.25meters width per apartment that holds, among others, thebuilding technology,“ says Ronald Ellebrecht, who supportsthe projects as a Key Account Manager for va-Q-tec. Extrapolatedto the 47 floors with an average of nine apartments perlevel, however, the area is quite large.
Large space savings due to thin insulation panels
The best thing about it is that the VIPs by va-Q-tec are onlyThe best thing about it is that the VIPs by va-Q-tec are only50 mm thick; common insulation panels would have been250 mm thick in order to achieve identical low-energy values.„This difference makes up a little less than three square metersof living space per floor in the Grand Tower,“ Ellebrechtexplains. „At 47 floors, the space saved totals up to about123 m².“ This corresponds to one spacious apartment, whichis valuable in a booming inner city like that of Frankfurt.„The purchasing price per square meter in the Grand Toweris between EUR 5,000 and EUR 15,000,“ Ellebrecht reports.This is not the least reason why insulation with VIPswas economically highly interesting for the builder, saysthe expert, along with other arguments that support thisinnovative insulation technique: „You can achieve the bestpassive building values with it, meeting the highest ecologicaldemands – and it is also a purely visual benefit if youdon’t have any corners protruding into your living room.“ More information.
Apartment and office building in Munich
The new building is located in a prominent area in Munich. Buildings in a central location in Munich like Seitz street, come with a high property value per m² and space is limited. A conventional insulation thickness of 25-30 cm is not economically reasonable here for a low-energy building. A conventional insulation of 25 cm would take up 125 m² more space in a building like this, this equals 10% of the useable area in the building. That's why vacuum insulation panels by va-Q-tec AG have been attached to the external walls. This was the first time vacuum insulation panels were used in a large building.
Through the application of 2 cm VIPs and 8 cm protection and covering material, it was possible to reach insulation values of a passive house without the loss of valuable living area. The VIP's were also used to minimize the step between the interior and the balcony! In some areas of the building VIP's were integrated into the window facade systems as well. In this case a good insulation value was reached with only 3 cm insulation thickness.

Rosslyn Chapel / Edinburgh in Scotland
The dilapidated medieval roof sealing over the nave led to persistent moisture penetration despite continual subsequent drying out. this caused immense damage to the historic building substance of Rosslyn Chapel.
With our highly-efficient vacuum insulation panels, it was possible to meet the urgent need for action. Through the use of va-Q-vip B vacuum insulation panels, a new roof insulation above the nave was constructed. Due to the low insulation thickness the historical character of the building could be retained.
