Porcelain is a ceramic tile that is made of finer clays fired at a much higher temperature. Glazed porcelain tile is a great choice for interior or exterior residential applications and is also a common product used in commercial settings. Glazed porcelain is one of the most durable products available, stain resistant and absorbs virtually no water, making it frost proof. Glazed porcelain is hard-wearing, making it an ideal tile for areas where scratch, water and stain resistance is a must, such as kitchen counter tops and bathrooms.
