One of the most durable building materials around is tile. Porcelain and ceramic tile are moisture resistant and require less maintenance than other materials used for flooring and wall covers. Tile is versatile and can be used in both residential and commercial applications. Both porcelain and ceramic can be used to cover walls, ceilings, counter tops, showers and back splashes. Ceramic is designed for indoor use. Porcelain can be used indoors or out. This designation is due to the higher moisture content of ceramic tile, which makes it more susceptible to freezing and thawing. Porcelain has a lower moisture content and is less likely to crack due to freezing.
