Fantastic facades with Super Spacer
Edgetech’s Super Spacer has been specified in three new highly sustainable buildings.
The Hoch Zwei office tower in Vienna boasts a distinctive convex-concave shape, earning nicknames like ‘sails’ and ‘croissants’.
This 23-story landmark incorporates 13,500m2 of glass facade, offering a unique blend of transparency, light permeability, and excellent thermal insulation.
Doering Glass – an Edgetech customer since 2004 – supplied 132 curved glass panels, each with six variations and reaching sizes of up to 1,500 x 4,000 mm, to form the building’s 2,000m2 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 design also included screen-printed sections on the glass panels, enhancing privacy and security, particularly in the facade’s outward-facing corners.
Just 400 meters away from Hoch Zwei lies the Vienna University of Economics and Business.
The university’s library features a visually striking white and black structure connected by a glass joint incorporating Doering Glass’ curved 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 5m and unfolded lengths of nearly 4m.
Doering Glass’ 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 1,400 curved aluminium louvres.
Doering Glass supplied over 1,000m2 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,” commented 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 35th birthday, Super Spacer is still making huge contributions to some of the most cutting-edge buildings on earth.”
