After the fire catastrophe of the London Grenfell tower in 2017, there is an increasing demand for non-flammable insulating materials supported by recent regulations on thermal insulators. Moreover, the growing debate over the high CO2 footprint associated to traditional thermal insulators fosters novel eco-friendly solutions. To address this impellent and “green” demand, FenX develops new insulating foam solutions combining uniquely non-flammability and environmental friendliness. Based on a research developed at ETH Zurich, FenX exploits the ideal properties of mineral particles including mineral waste, resulting in highly porous foams that can be created through advanced processing methods, such as extrusion or 3D printing. With this novel and protected technology, the startup aims to design and produce insulation foam products, including panels, bricks and customized parts targeted for the European markets but also emerging markets (Brazil, South Africa) where industrial waste is available. These products are non-flammable, highly insulating, non-toxic, recyclable and eco-friendly yielding low CO2 emissions during manufacturing.
