Corobrik’s Face Bricks Offer Smooth Finish to Radisson RED The Radisson RED hotel is a vibrant addition to Cape Town’s V&A Waterfront with construction including one of Corobrik’s popular face brick range. T he use of natural materials, such as Corobrik’s clay product, contributed towards the 5 Star Green Star rating awarded to the Radisson RED hotel building (Silo 6) – the first ever Green Star Custom Hotel rating for ‘new build’. “The incorporation of Corobrik’s face- brick into this artistically-designed hotel façade proves the incredible diversity of the product,” said Christie van Niekerk, Corobrik Manager for the Western Cape. The Radisson RED is the first hotel countrywide to receive an outstanding 5 Star Green Star Custom Hotel design rating for a new build, setting the benchmark for other hotel design and construction projects. Manfred Braune, executive director: Certifications at the GBCSA, said that this is an exciting moment for green building in South Africa, signalling the move of green buildings into the hospitality sector. “This is not just about doing the right thing, although that is, of course, vital in the face of our local and global environmental challenges. It also makes good business sense to build green and, going forward, 36 we look forward to further green trans- formation in the hospitality sector in South Africa. Hotels such as Hotel Verde and DoubleTree have achieved Green Star ratings for their existing operations, and now the Radisson RED is the first hotel to receive a Green Star rating for its design and construction – hospitality is definitely going green.” The hotel was built using 160,000 of Corobrik’s De Hoop Red Smooth Blended face bricks for the exterior. Selected for its extreme durability, heat resistance and sound insulation properties, the clay brick is ideally suited to the harsh micro-climate and harbour conditions experienced on the V&A Waterfront. Architectural firms, DesignSpaceAfrica and Peerutin Architects, opted for ‘second grade’ De Hoop bricks because of the imperfections that would achieve the weathered look they desired. This particular Corobrik product is zoned for use in these unique circumstances with this project requiring second grade bricks with clean lines. Because of the hotel’s location within the Silo district, architects wanted to create a robust building with industrial character suited to its surrounds while providing a unique aesthetic presence that has an impact. “The industrial character we wanted was achieved by the irregular brick coursing as opposed to the typical, clean face brick coursing,” explained Luyanda Mpahlwa, lead architect on the project and director of DesignSpaceAfrica. “The imperfections of this brick were ideal for this, and mortar was laid flush with the brick to create a more coherent but textured façade finish. The industrially produced, dark-stained and sleek aluminium window pop-outs provide an interesting contrast to the light grey- coloured random face brick coursing. This contrast makes the façade unique, with the pop-outs also provide sun shading during the peak hours of hot sun early morning and midday.” However, the architects wanted a more toned-down hue than the red of the De Hoop so they selected Keim, an external wall finish that allowed them their colour of choice with the silver wash. Keim is a naturally-based organic and durable paint application which can be applied with a render and weather-protective layer to improve the quality of the mortar to the same standard as the face brick, all while preventing moisture penetration. The final effect is subtle light grey finish with a silver, metallic wash that gives the façade a special shimmer when sunlight hits it. Advertorial
