HeiQ receives the German Sustainability Award for Products for its Xpectra technology, as detailed in a press release. The coating is sprayed onto buildings and reflects up to 74 per cent of heat radiation. According to the jury, the spray coating makes it easier to retrofit existing buildings in particular: “With this award, the jury is highlighting an innovation that shows how material-efficient technologies can simplify and accelerate the energy-efficient refurbishment of buildings and thus make an effective contribution to climate protection.”

Xpectra is managed within the Schlieren-based HeiQ Group by HeiQ Xpectra GmbH, which is based in Regensburg, Germany. HeiQ will accept the award on 4 December in Düsseldorf. The company is now planning to scale the technology in Europe, North America and the Asia-Pacific region. “The German Sustainability Award is a successful example of HeiQ as an innovator of deep-tech materials and of our joint commitment to innovation and sustainability,” Oliver Zech is quoted as saying. He is the CEO of HeiQ RAS AG, which is also based in Regensburg. “The award strengthens our position on the market and opens up new opportunities for joint marketing.”

HeiQ is a spin-off of the Swiss Federal Institute of Technology in Zurich, is based at the IJZ Innovation and Young Entrepreneur Centre and is a member of Start Smart Schlieren.
