Some ceramic tiles are even made to look like other materials. Imitation slate tiles, for example, are a lot less porous than stone and require less maintenance.
Ceramic tile is divided into five categories, or "classes", depending on resistance to wear. Class 1 rated tiles are the least resistant and for use only on walls, while Class 5 rated tiles are the most hard-wearing and especially suitable for floors in high-traffic areas.
Glass is more fragile than stone or porcelain, which makes it more difficult to cut. Glass tiles should be set with a special type of adhesive and white grout to ensure the colour is not altered. Versatile and easy to clean, glass tiles have become a firm favourite.
Stone tiles are porous and therefore vulnerable to marks and stains; regular application of a sealer is recommended to protect the surface and prevent them from absorbing dirt. Nevertheless, they are highly durable and, if properly cared for, can last a lifetime.
This type of tile is relatively difficult to clean and must be coated regularly with a sealer; however, it is extremely hard-wearing and, if looked after properly, will last for many years. True terracotta tiles acquire a patina over time.
They are produced in a wide variety of colours, patterns and textures. These tiles are heavier than ceramic tiles, but they are particularly resistant to wear and to temperature fluctuations.
