DuPont™ SentryGlas® delivers vital functional, structural and aesthetic performance for new Morocco Telecom HQ in Rabat

14.09.2012
The façade covering Morocco Telecom's new headquarters in Rabat is another stunning demonstration of the comprehensive capabilities of DuPont™ SentryGlas®.

The facade construction used on the new building, designed by architects Jean Paul Viguier et Associés, Paris, comprises a double skin covering a total surface area of 11,500m2. The exterior of the skin is composed of vertical shoulders mounted on a stainless-steel structure, for wind mitigation, bearing a curtain-wall made of laminated glass panels. The laminate panels, each measuring 1,480 x 3,503mm, comprise 10mm Ipasol bright tempered HST, 1.52mm SentryGlas® and 10mm float tempered HST.

The facade on Morocco Telecom's new headquarters in Rabat comprises a double skin covering a total surface area of 11,500m2. The exterior of the skin is composed of vertical shoulders mounted on a stainless-steel structure, for wind mitigation, bearing a curtain-wall made of laminated glass panels, each measuring 1,480 x 3,503mm, which comprise 10mm Ipasol bright tempered HST, 1.52mm SentryGlas® and 10mm float tempered HST.

By deploying laminate panels incorporating SentryGlas®, the architects were able to address a number of important structural and functional demands; one of which was the high daytime temperatures and the large night-time temperature differential. During the day, the frontage of the building can quite easily see temperatures up to 70°C; something which immediately precludes the use of PVB-based laminates, as they are only certified up to 64°C by French building regulations. The superior thermal performance offered by SentryGlas® therefore made it an ideal candidate for this installation and, indeed, for others that face even higher temperatures, as SentryGlas® is up to 80°C.

Thanks to SentryGlas® being 100 times stiffer and five times stronger than PVB, the architects were also able to design and specify laminate panels some 30% thinner and, as a result, significantly lighter, than PVB-based alternatives.

With SentryGlas® there is an almost perfect transmission of load between two laminated sheets of glass – even at high temperatures – leading to excellent flexural behaviour when under load. As a result, laminates constructed with SentryGlas® show less than half the rate of deflection when compared to laminates incorporating PVB under the same load. Indeed, the deflection figure is very close to that exhibited by monolithic glass of the same thickness.

In this application, the deflection characteristics were also of particular importance due to the seismic activity experienced in the region. Should the worst happen, SentryGlas® laminates show excellent post-glass-breakage performance due to the strength of the interlayer. Upon impact, the glass may break, but dangerous fragments will adhere to the SentryGlas® interlayer, reducing the risk of injury to people in the vicinity.

"The impressive thermal performance of SentryGlas® was a vital consideration in this installation, especially its ability to function in temperatures up to 80°C. In addition, the ability to provide this level of functional and structural performance, especially with regards to angular wind resistance, using a thinner laminate construction gives us the scope to create less intrusive and more subtle support structures," explains Tomaso Mani, from Jean Paul Viguier et Associés. "This, in turn, gives us greater design freedom coupled with the ability to create more innovative building concepts that are not fettered by extensive external support frameworks."

Constructed by Italian laminator Zadra Vetri S.r.L., the laminate panels using SentryGlas® were also successfully tested to a number of important building test standards, including: Cahier 3574 (VEA) wind test with security load (wind equal to ±6000Pa), Cahier 3533 Stabilité en zone sismiques – seismic test; EN 12543-4 – irradiation test (4,000h); and NF P 08 302 – body impact test M50. The use of SentryGlas® in this application was also the subject of an 'Avis Technique' certificate from CSTB, further adding to its credentials.

As well as its numerous functional advantages, SentryGlas® interlayers provide multiple aesthetic benefits, including high, crystal-clear transparency, virtually universal resistance to yellowing and excellent edge stability; all of which are important to the long-term aesthetic appeal of the building and the quality associated with Moroccan Telecom's brand.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
