Curtain Wall Façade of Laminated Glass with High-Strength DuPont™ SentryGlas® interlayer Maximizes Safety for Vienna's Ares Tower
The Ares Tower, one of Vienna's tallest office buildings, has a double skin with a newly installed laminate glass curtain wall façade. Thanks to the use of DuPont's SentryGlas® interlayer, the façade's individual panels are neither thicker nor heavier than the previous single pane glazing, meaning that replacement could be carried out quickly and at high cost efficiency.

As Walter Mayer, Chief Executive of MGT, explains: "Using conventional PVB interlayers would have meant using a distinctly thicker laminated glass structure in order to meet regulatory requirements for maximum deflection under wind loading. This would have meant that this refurbishment could not have been carried out within the specified time and cost
constraints. Because we used the SentryGlas® interlayer, we were able to make direct use of the existing load-bearing structure while meeting all requirements."
Thanks to its higher post-breakage stability, particularly high transparency and greatly reduced yellowing, such laminated glazing with SentryGlas® is not only of interest in refurbishment
projects but also opens up many exciting prospects for architectural design. And for building owners, laminated glazing with SentryGlas® has economic advantages since this interlayer has much better moisture resistance than conventional PVB, ensuring high levels of edge stability and weathering resistance over many years.
