These 13 mm thin facade panels are made of a new CO₂-Reduced Glassfibre Reinforced Concrete. The innovation lies in the addition of natural, locally available pozzolans, which will gradually replace the cement – in this product, it has already been replaced by 50 per cent. The idea is based on the cast masonry of the Roman Pantheon, to which the ancient builders added volcanic ash, trass and other minerals known as pozzolans. The new facade panels are robust, fire-resistant and durable. “The use of local, naturally occurring materials results in lower CO₂ emissions, making the facade elements more sustainable,” the judges stated.
