1 / 5 Principle Blue

Principle is a tile collection made from 91.3% recycled materials. This includes unfired tableware/stoneware residue, tile dust from regular tile production, vitrified ceramic stoneware, recycled glass bottles and window glass. The range is available in a palette of four contemporary shades that present our take on the timeless tiles of the Victorian era, complete with a unique glaze for a deep, rich finish. This product diverts a massive 8KG from landfill for every m2 produced, locally sourced by the manufacturer in Spain, and requiring a 23% reduction in gas during production - contributing to overall reduced energy consumption.

Our materials are dry pressed and then sintered, our tile products fall under British Standards for ceramic tiles. Independent formal test certificates are available on request.

Care & Maintenance

Silicastone products are easy to care for and can be left in their natural state in many cases. However, depending on your chosen application it may be necessary to periodically apply a surface sealant to the product.


Most of our products are, by their nature quite heavy, akin to natural stone. Weights will vary depending on product but they can weigh up to 45kg per m2, so we only recommend installing on a suitable substrate.


Our products are made from no less than 98% recycled materials and approximately 60% of those materials currently ends up in landfill. For some of our coloured ranges we need to add materials that are not recycled, but our products are always more than 98% recycled.
