Ceramic Flooring
Most types of tiles made from clay or a clay mixture and kiln-fired are considered to be a part of the larger classification of tile called ceramic. These tiles can be split into two groups, porcelain tiles and non-porcelain tiles; non-porcelain tiles are commonly referred to as ceramic tiles.
Non-porcelain ceramic tiles are generally made from red (often terra cotta) or white clay that’s fired in a kiln. When shopping for ceramic tiles, you may notice something called a PEI rating. Developed by the Porcelain Enamel Institute, this rating system is the only reliable gauge for consumers to use in determining wear expectations for a particular tile application.
- PEI Class 1 Rating (no foot traffic): Recommended for wall use only in residential and commercial applications.
- PEI Class 2 Rating (light traffic): Recommended for both wall use and bathroom-floor applications.
- PEI Class 3 Rating (light to moderate traffic): Recommended for countertops, walls and floors where normal foot traffic is expected.
- PEI Class 4 Rating (moderate to heavy traffic): Recommended for all residential applications as well as medium commercial and light institutional.
- PEI Class 5 Rating (heavy to extra-heavy traffic): Recommended for all residential as well as heavy commercial and institutional applications.
Ceramic usually carries a PEI rating of 0 to 3 and is suitable for light to moderate traffic. It is more water-absorbent than porcelain and more prone to wear and tear. That said, ceramic generally costs less than porcelain tiles. It is also easier to cut with a basic tile saw, so homeowners may prefer ceramic for DIY projects.
Ceramic tile is strong, colorfast and flame-resistant. It doesn’t conduct heat or electricity; it’s hygienic; it won’t absorb odors or emit hazardous chemicals; it won’t swell or contract in extreme temperatures; and it’s easy to clean. Given its durability and versatility, ceramic tiles can be used in a wide array of locations in your home, including bathroom countertops, kitchen backsplashes and floors in any room. “Ceramic tile is an optimal selection for walls, often providing a color palette not available through other tile categories.
Porcelain tile is generally made by firing clays at a very high temperature, resulting in a tile that’s dense, impervious, fine-grained and smooth. Porcelain tiles usually have a much lower water absorption rate than ceramic tiles, making them more frost-resistant, although not frost-proof. Glazed porcelain tiles are much harder and have more damage resistance than ceramic tiles, so they should be suitable for almost any indoor residential application, most porcelain tiles have a PEI rating of 5. Given their low porosity and durability, porcelain tiles are a good candidate for areas that receive high traffic or are prone to getting wet, such as showers and bathroom counters. “Porcelain is generally suitable throughout the home but should be selected with care,” says Cherkas. “Lacking the warmth of natural stone, porcelain tends to make spaces feel colder.” The toughness and durability of porcelain make it hard to cut with a basic tile saw, so it may not be an optimal choice for DIY projects. Professional installers will have the correct tools to cut porcelain cleanly and concisely. Porcelain is also relatively expensive compared to ceramic, so costs may add up for larger projects.
Slate is a fine-grained, metamorphic rock, commonly derived from sedimentary rock shale. It’s composed mostly of micas, chlorite and quartz and is best suited for floors, walkways, roofing, kitchen countertops and wet bars. It’s a dense, tough composite typically available in blacks, grays and greens, although it can also be found in many other colors. Slate shades within the same color family often vary. Veined patterns from overseas are also available. Unless it has been honed smooth, slate’s surface can be recognized by its distinct cleft pattern, it has a gorgeous texture and wears nicely without the constant worry that it is too precious. While slate is known for its striking appearance, it falls on the higher end pricing for tiles. Slate tiles are also tricky to install on your own, so you will need to hire a professional. During installation, you must seal the slate to fill the pores and then seal it again for surface protection. Given the cost, some homeowners reserve slate for higher profile areas of the home such as the entryway.
Marble is one of the more popular natural stones, formed from fossil sediment deposits that have been pressed by the natural geologic forces of nature for millions of years. Much as diamonds are created from coal, marble was once limestone that underwent a metamorphosis from the intense pressures and high temperatures within the earth. Marble is available in unique colors with veining of great depth and intensity. Most marble products are softer and have more porosity than granite. Because it’s softer, it’s most often used in bathro0mwalls and flooring. as well as for tub decks, fireplace surrounds, furniture, sculptures and courtyards Marble is not recommended for kitchens unless the stone is honed and sealed. “For higher traffic areas, a homeowner may want to avoid using a highly porous material like a Carrera marble, but in a guest bathroom or a powder room it could be absolutely doable.” Marble is a high-end tile material and can cost twice as much as ceramic, or even more for certain types of marble. Installing marble tiles is tricky for invoice installers since marble breaks easily and requires specialized tools to cut. It is best to hire professional installers to avoid losing money on tile breakage.
Limestone is a sedimentary rock consisting mostly of calcium carbonate and is formed from the remains of ancient sea life such as oysters and mussels that have been compressed over millions of years. It is found in great abundance in many parts of the world, generally in earthy colors such as off-white, gray and beige. Limestone is less dense than marble or travertine (itself a form of limestone), but limestone that contains the mineral dolomite is hard enough to be polished to a shine much like marble can be. Its best uses are for structural walls, entry walls, floors, fireplace surrounds, vanities and shower walls. It’s generally not recommended for kitchen countertops and wet bars, because fruit juices and alcohol products can stain them. It’s also prone to scratches, Limestone is relatively affordable compared to other stones like marble or slate. If you’re looking for a natural stone but are working with budget constraints, this is a good option. Since limestone is a softer tile material, keep in mind that it’s prone to cracking and breaking, which can make installation difficult. Limestone is also porous, so grout can easily seep into the pores during installation, complicating the grouting process.
