Ceramic tiles can be glazed or unglazed. Glazed tiles are available plain or decorated and can be used on walls and floors.
Unglazed ceramic floor tiles are more suited to commercial and industrial settings, but can be used in laundries and utility rooms. They are available with a non-slip profile.
Quarry tiles are a traditional product made in the UK for hundreds of year. They are made from natural clay, squeezed through an extruding machine, and then fired. They are mostly available in terracotta, black and white colours.
Terracotta tiles are also made from local clays. Terracotta means “cooked earth” and these products tend to be very absorbent, so need sealing when used on the floor.
Porcelain tiles are ceramic tiles, but with a very low absorbency. They are usually made from kaolin clays, feldspar, silica and colouring oxides and are fired at about 1200oC. Porcelain tiles are hard wearing and can be used on walls or floors.
Mosaics are very small tiles, usually less than 35cm2. Mosaics can be glazed or unglazed and made from porcelain, ceramic, glass or natural stone.
Natural stone products; limestone, marble, granite and slate are quarried from the earth. Some are extremely hard, and some quite soft. Some may need sealing.
