DEPARTMENT OF ENVIRONMENTAL AFFAIRS

The product range created by the convection furnace has received attention from noteworthy role players in the industry. Our products have recently been specified in some significant projects, including the offices of the Department of Environmental Affairs, managed by the Pretoria branch of Boogertman and Partners.

The design called for high performance double glazing in a thermally broken curtain wall to conform to stringent U Value requirements.

Energy modelling showed that glass with high luminous efficacy was needed to ensure the correct level of natural daylight, without heat energy entering the building. The architects specified 5 500 m2 of Thermoshield Stopray Vision 50T on Clearvision and Thermoshield Stopray Titanium 37T in order to meet these requirements.

The project brief from the Department of Environmental Affairs called for clear glass. Thermoshield Stopray Vision 50T on Clearvision was specified as it met all the performance and aesthetic requirements.

The Architects opted to use Stopray Vision 50T on Clearvision for the well shaded north and south facing facades, and Stopray Titanium 37T on the east and west facades to deal with the low morning and late afternoon sun. After testing using energy modelling, the building was awarded with a six star office V1 design rating, making this the third and largest six star rated building in the country and the first six star rated Government project.
