Edgetech Case studies

Edgetech’s Super Spacer® has brought exceptional performance to three striking, ambitious and outstandingly sustainable buildings.

Hoch Zwei

The Hoch Zwei office tower in Vienna boasts a distinctive convex-concave shape, earning nicknames like “sails” and “croissants.”

This 23-story landmark incorporates 13,500 square meters of glass facade, offering a unique blend of transparency, light permeability, and excellent thermal insulation.

Doering Glass – Edgetech customers since 2004 – supplied 132 curved glass panels, each with six variations and reaching sizes of up to 1500 x 4000 mm, to form the building’s 2000-square-meter rounded corners.

The double-glazed units feature a combination of laminated safety glass, PVB film, solar control glass, argon-filled interspaces, and low-emissivity glazing, achieving a U value of 1.5 W/m²K and a light transmittance of 39%.

The meticulous design also included screen-printed sections on the glass panels, enhancing privacy and adding a touch of security, particularly in the facade’s outward-facing corners.

Vienna University of Economics and Business

Just 400 meters away from Hoch Zwei lies the Vienna University of Economics and Business.

The university’s library, designed by the renowned architect Zaha Hadid, features a

visually striking white and black structure connected by a glass joint incorporating Doering’s glass panels.

The most prominent feature of the LLC is the “monitor” – a projecting roof with a curved window front.

The complexity of the building’s design extends to the curved glass itself, reaching heights of up to 5 meters and unfolded lengths of nearly 4 meters.

Sixty London

Doering’s expertise in curved glass extends to London’s architectural landscape as well.

Sixty London, a 9-story office and retail building designed by Kohn Pedersen Fox Associates, features a curved facade that complements the surrounding Victorian architecture.

The building’s organic design incorporates approximately 1400 curved aluminium louvres, adding a captivating dimension to the facade.

Doering Glass supplied over 1000 square meters of curved and concave insulating glass for the facade and roof terrace balustrades.

“These three products are fantastic examples of the sort of exceptional unit performance and design freedom Super Spacer® enables,” comments Edgetech President of European Fenestration Chris Alderson.

“Its ability to seamlessly follow the contours of curved glass were essential to delivering both the desired aesthetics, but also outstanding robustness, longevity and thermal efficiency.

“All three buildings show how, even as we celebrate its 35^th birthday, Super Spacer® is still making huge contributions to some of the most cutting-edge buildings on earth.”
