Porcelain tiles usually cost more than ordinary ceramic tiles.
This is because customers are getting a superior product for the price they pay. Porcelain tiles typically use the finest natural ingredients and the most advanced technology in a rigidly controlled manufacturing process.
Harder and Denser
Porcelain tiles are much harder and denser that ceramic tiles since they are made from an extremely finely powdered clay tablet pressed under enormous pressure and heat – several hundred degrees hotter than ceramics. This also allows porcelain tiles to be made in very large formats that would be impossible to achieve in a ceramic tile.
Porcelain tiles will also often have a coloured biscuit that matches the surface glaze, or have a colour and pattern that extends all the way through the tile. This avoids the common problem with ceramics where the glaze gets chipped and exposes the colour of the clay biscuit underneath.
Porcelain tiles are the strongest fired product that you can purchase in tile form and many are commercially rated; strong enough to be used outdoors or in a shopping mall. If you are using the tile for a very high-traffic area like kitchens, a porcelain tile would be a great investment.
Porcelain tiles have typically 0.5% or less of water absorption which means it is less porous, making it easier to clean and less likely to stain.
As long as the tile does not come to impact with any heavy or sharp objects causing chipping, tiles should last for the life of the home. Tiles were found intact in the ancient ruins of Rome and various other places. After all, it’s made of finely ground stone, and hardened in a kiln. Just basic maintenance and avoiding heavy drops should definitely keep tiles looking great for many years to come. This is true for both ceramic and porcelain tiles, however being denser and stronger, porcelain proves to be more resistance to chipping.
Frost can damage tiles when water is absorbed by the tiles gradually. The water then cracks the tile when it expands as it freezes. Then when it melts, it takes crumbling pieces of the tile with it. The less the tile absorbs the less damage the water does when it freezes.
Good quality porcelain tiles are usually rated to be frost resistant. This is an important consideration in areas where temperatures can drop to below zero degrees.
