Do tiles contain substances which are harmful to the environment?
No. The manufacturing process is free of toxic substances. Tiles consist of mineral raw materials, primarily silicon and aluminium. Plastic raw materials are clays and kaolin, hard materials are feldspar, quartz, chalk and dolomite. As a result of the firing process the tiles no longer contain any organic compounds, which means that they do not represent a health risk (the ideal covering for people who suffer from allergies). Tiles from Villeroy & Boch comply with the quality requirements of European quality standards DIN EN 159 and DIN EN 176.
