Frequently Asked Questions

What are the differences between porcelain and ceramic tile?

Porcelain is usually manufactured from white clay rather than red clay and is fired at a hotter temperature, resulting in a denser product. It is less absorbent than ceramic and more chip-resistant. Porcelain is more difficult to cut than ceramic tile. In most applications, ceramic tile is a good product for interior walls, but porcelain is a more durable choice for floors and outdoor projects.

What does "rectified" mean?

"Rectified" refers to tile that has been cut mechanically after firing so that each tile is exactly the same size. In nominal sizing the tile shrinks somewhat during firing, resulting in minor variations in size. The main advantage of rectified tile is that a thinner grout joint can be used.

What is subway tile?

Subway tile got its name because it was the material used in the New York subway tunnels in the early 1900's. Traditional subway tile is glossy white, rectangular, and measures 3"x6". Due to its recent resurgence in popularity, it is now available in many different colors, finishes and sizes, including glass and stone.

What is a PEI rating?

PEI stands for Porcelain Enamel Institute and gives a rating of one (wall only) to five (heavy commercial use) for hardness and durability of tile. It is useful for determining the suitability of floor tile for the amount of expected foot traffic.

What is through-body porcelain?

Through-body porcelain is a high quality tile that is consistent in composition throughout the body of the tile. It is chip resistant, but the body is a similar color if a chip does occur. These tiles are usually freeze/thaw stable and are appropriate for exterior use.

What does COF mean?

COF refers to the Coefficient of Friction, which rates the slip resistance of floor tiles. A rating of .60 or better is recommended for most applications.

What are the differences between man-made tiles and natural stone?

Natural stone is beautiful and unique but requires more care than porcelain or ceramic tile. Natural stones are more porous so they may scratch and stain more easily. Stone needs to be sealed regularly and should be cleaned with a PH-balanced product to avoid damage. Many of the new "high definition image" porcelains are very realistic and are nearly undetectable as faux stone.
