Most types of tiles that are made from a form of clay or a clay mixture, which are then kiln-fired, are considered to be a part of the larger classification of tile called ceramic. These tiles can be split into two groups, porcelain tiles and non-porcelain tiles. These non-porcelain tiles are commonly referred to as ceramic tiles.
Non-porcelain ceramic tiles are generally made from a red or white clay that is fired in a kiln. Ceramic tiles are suitable for light to moderate traffic and have a higher water absorption rating that makes them less frost resistant than porcelain. In addition, they’re usually more prone to wear. However, with new technologies, ceramic tile should always be considered by its specifications, as durability and other factors will vary between ceramic tiles. Ceramic tiles generally cost less than porcelain tiles.
Porcelain tile is generally made by pressing porcelain clays, which results in a tile that’s dense, impervious, fine grained, and smooth with a sharply formed face. Porcelain tiles usually have a much lower water absorption rate than ceramic tiles, making them more frost resistant, although not frost proof. Glazed porcelain tiles are much harder and have more wear- and damage-resistance than ceramic tiles, making them suitable for any residential and light commercial application.
