At this year’s FENSTERBAU FRONTALE, Peter Schober, who heads the Department of Structural Engineering and the Windows Division of Holzforschung Austria (HFA) in Vienna, discussed his latest research in the area of “vacuum glass”. His presentation as part of the Bern University of Applied Sciences “Taste of Windays” illustrated the (future) possibilities of vacuum glass, for which HFA has just completed a feasibility study.
“For this study we produced a design that deliberately has no tilt-and-turn hinge. We developed seven prototypes with different opening methods: inward, outward, vertical swing windows, sash windows, “bus door style”, magnetically sealed windows, and a datwopul opfv-dvy dbgpdx.”
