Stopray was also used in the Fluxmans building in Rosebank designed by Paragon Architects. Paragon specified 3 600 m2 of C&C Safety Glass’s Thermoshield Stopray Vision 50T on Clearvision for a floor-toceiling, high performance flush double glazed curtain wall that had to be as transparent as possible while overcoming challenges in terms of thermal performance, adequate solar shading, glare control and budget.

According to the Architects, the high performance to relatively clear appearance ratio was extremely appealing when compared to glass with the same level of performance. They were also impressed by the aesthetic of the glass in varying lighting conditions, which tied in with their clean, minimalist design.

These projects boast some of the highest U Values possible in South Africa. At a U Value of 1.0 W/m2.K, the Department of Environmental Affairs building is the highest specification double glazed building in the country, which matches European standards.

C&C Safety Glass is very proud to have been awarded the glass supply on the prestigious Sasol building, commencing early 2015. Paragon Architects believes that the new Sasol Corporate Offices in Sandton has a powerful architectural form which needed an equally powerful facade to emphasise the building envelope. A highly selective, Double Silver Low E Coated Thermoshield Stopray Vision 36T, reflective vision glass was selected for its performance parameters and its ability to reflect light and sky. The spandrel glass choice needed to feed into the overall reflective language, thus the selection of the bespoke silver back painted glass textured panel, Safetyshield Imagin Krizet with Ipachrome TC coating. The custom textured spandrel panel subtly reflects light as it moves over the building, reinforcing the iconic and unique language of the building.

Pure Consulting Facade Engineers selected Stopray Vision 36T as the primary vision glass for the Sasol Corporate Offices as a result of several months of in-depth modelling and analysis. The high spectral selectivity of the product meant that vision glazing was able to be maximised, ensuring high levels of natural lighting into the offices, without compromising the necessary thermal performance of the facade. Additional factors that led to the selection of the Stopray Vision 36T was its ability to be toughened and curved, as well as its silvery external appearance which supported the architectural intent of the building.
