Porcelain tile is a type of ceramic tile. The difference between porcelain and ceramic is that porcelain is fired at a higher temperature, making it more dense and moisture-resistant. Porcelain tiles are also less porous, making them more stain-resistant. For these reasons, most porcelain tiles are suitable for both indoor and outdoor installations. Porcelain tiles are hard to cut due to their density and hardness, so the cost and labor involved is often higher. Porcelain tiles are available in matte, unglazed or a high-polished finish. In recent years, the prices have become closer to those of ceramic tile.
Porcelain Tile is also a very common trend in tile installation. There are many different styles of porcelain tiles on the market and they have proved to outperform ceramic tile in durability and looks.
It is important to note that the differences of the body of the porcelain tile, as it relates to ceramic tile, has caused many "job failures" of tile installations. Tile setters that are self trained and novices to the industry will often use cements or mastic to install the impervious body of the porcelain tile to a substrate only to have delamination occur rather quickly. Highly Modified cements are necessary for installation of this material due to the very qualities that make it such a durable long lasting decorative surface. Those specifications are determined by and dictated as industry standards by the Tile Council of America, and supported by the Tile Contractors Association.
