Building Materials and Construction Components Design Bioxide Tile Roof Tile by Ettore Giordano The research challenge was to design a roof tile from a functional and aesthetical point of view. Bioxide Tile includes Hematite, which is an iron mineral, twice as much as normal tiles. Bioxide Tile, comparing to tiles produced with traditional raw materials, is more resistant to natural conditions, lasts longer and is more aesthetical. Bioxide Tile has unique technical features such as: high frost resistance, improved water isolation, improved noise isolation, better heat isolation. There is no free calcite mineral in Bioxide Tile. Ettore Giordano developed this new product with ECE holding.
