„For us the Belvedere is a flag ship project”, said Hanspeter Petschenig, CEO of „Petschenig glastec GmbH”, the company that provided the IG units for the facades. The project included some special bend panes that came from German. The company Flintermann Glasveredelungs GmbH, based in Lower Saxony, Germany, contributed by providing curved insulating glass elements for some of the building edges. "The demanding geometry of the glass panes really did put our team to the test," explains glass specialist Reinhard Gruber from Flintermann (www.flintermann-glasveredelung.de).
Five large-format single panes, tapering straight at the ends and a central bend with a very narrow radius, have been combined with Super Spacer TriSeal Premium Plus to form triple-glazed insulating glass units.
The 342 apartments and the 303-room hotel complete with skybar, ballroom and a large convention area are spread over five towers with polygonal floor plans that are set up on slender pylons measuring several meters in height.
28,000m2 facade is being put to the test
A 28,000m2 mullion-transom facade was chosen for the ground floor of the two hotel towers that are designed in the form of an elemental facade.
Among other things, Strabag Metallica that was in charge of the project, installed 60,000 grey glazed ceramic strips with a total weight of 770t and 1,100 triple insulating glass units within the 5,600 facade elements. Just six months passed from the issuing of the order in May 2017 to the installation of the first element.
A Herculean task, due to the fact a time-consuming testing process had to be gone through between the planning or design, and manufacture of the components. All elements had to prove during the simulation as well as on the test bench that they meet the high civil engineering requirements placed upon the thermal insulation and sound insulation.

Precise and rapid: automated spacer application
"Without an automated insulating glass line, a project with such tight deadlines and quality specifications is virtually impossible to tackle", Hanspeter Petschenig confidently claims. "The robot-controlled application of the flexible Super Spacer guarantees the total parallelism of the glass panes on the one hand, on the other hand the production is, of course, performed much more quickly since a flexible, thermo-set spacer does not have to be bent, nor filled, connected and PIB-applied.
Especially where large, floor-to-ceiling panes are concerned, such as those used in the Belvedere project, the precise application down to the last millimetre of the flexible warm edge spacer constitutes a decisive criterion. The appearance of a spacer is assuming ever increasing performance according to Petschenig. "Super Spacer reflects the colour of the frame profile and thus appears completely neutral in colour," he explains.
