Tile tips How to choose the type of tile that is right for you Where is the tile being installed? The most important factor to consider when choosing a type of tile, is where it will be installed. Not all tiles are suitable for all applications. However, whatever type of tile you choose, if it is installed properly, it will bring a lifetime of function and beauty to any installation. Glazed products perform according to the hardness of their glaze. This hardness is determined by the manufacturer and rated using a PEI scale (Porcelain Enamel Institute). This PEI rating will determine the proper usage of each product. PEI ITiles suitable for interior wall application. PEI II Tiles suitable for residential bathrooms where softer footwear is worn. PEI III Tiles suited to general residential traffic, except kitchens, entrance halls, and other areas subjected to continuous heavy use. PEI IV Tiles suited for all residential and light to medium commercial areas. PEI V+ Tiles suitable for heavy traffic and wet areas where safety and maximum performance are a major concern such as exterior hallways, food service, salad bars, building entrances, around swimming pools or shopping centers. All tiles are suitable for interior wall use. Many tiles have a glazed surface. Glaze is liquid glass that is sprayed or poured onto the surface of the tile. It is then fused to the body of the tile using tremendous heat during the firing process. Strength and wear resistance are determined by its hardness. The following factors will have an effect on the glaze hardness: Temperature – Higher temperatures result in harder glaze. Color – Dark glaze colors such as blacks and blues are usually softer than the lighter color glazes. Gloss Level – Shiny glazes are usually softer than matte or satin finished glazes. What if your tile is not glazed? Since unglazed products do not have a glaze, they do not have a PEI rating, but can be installed anywhere - interior or exterior. However, unglazed tiles are more susceptible to staining and mold. It is not advised to install these products in wet areas, unless the tile will be maintained with a penetrating sealer on a regular basis. What look do you want? The shading and texture of the product are other factors to consider. Do you want tiles with a smooth surface or a rough, textured surface? Do you want the tiles to all look the same, or have some or a lot of variation for a unique installation? Whatever the look you decide, keep in mind that shade variation is inherent in all fired products. Many tiles are deliberately produced with a wide shade variation in order to capture the natural beauty of the product. CERAMIC TILE All of the raw materials that go into making ceramics come from the earth, including the colors of glaze… and this is a real testament to the quality of the product. While there have been successful methods to improve most products by substituting natural materials with synthetic, like vinyl and carpet, there are no such methods to improve the quality of the raw materials found in ceramics. They have changed very little over the past thousand years. GENERAL CHARACTERISTICS OF CERAMIC TILE: All ceramic tile share unique and exceptional qualities found in no other type of decorative building products. (Abrasion resistance) How will a tile’s glaze or surface hold up under continuous wear? This is a very important consideration when choosing any glazed floor tile. Commercial areas, as well as areas of the home subjected to heavy usage, such as kitchens or foyers, demand good abrasive resistance. If the right product is chosen and if it is maintained properly, (kept free of sand and grit), it could easily last the lifetime of the home. NOTE: Abrasion resistance is not a factor when selecting an unglazed tile. (Water absorption) The glaze on ceramic tile is non-porous. Therefore, when referring to water absorption, it pertains only to the tile’s body. The water absorption of the tile is important to know in order to make the right selection for outdoor use. If the tile absorbs more than 3% moisture, it is not suited for outdoor use in cold climates where it may freeze and crack. (Frost resistance) Frost resistance goes hand in hand with water absorption. The less water the tile absorbs, the greater it’s frost resistance. Your labels will clearly identify those tiles which are frost resistant. (Stain resistance) Ceramic material in general is the most stain resistant building product in the world. Glazed tile and even some unglazed tiles resist practically all solutions that could cause staining in other types of products. (Slip resistance) The slip resistance of ceramic tile in ordinary applications is comparable to that of most hard surface flooring materials and it is significantly better than some. Unglazed tiles have greater slip resistance than glazed tiles and are recommended for areas subjected to high water spillage. Many glazed and unglazed tiles also feature an abrasive grit on their surface, increasing their slip resistance substantially. These tiles are particularly suited to public areas with direct access to the outdoors. (Color permanence) While most colored materials will be altered by long exposure to light, colors in ceramic tiles are unaffected and will not change or fade from exposure. (Dirt resistance) Ceramic tiles do not retain dust or residues. Plain water or a damp cloth is generally all that is required to keep the tile clean. With the exception of tiles such as Terra-cotta, which may be optionally oiled or waxed, no polishing or buffing is necessary to maintain the finish. (Fire resistance) Ceramic tiles are completely fire-proof at any temperature. They will not burn nor fuel a fire. The surface will not alter, nor will it give off any toxic gases, smoke or fumes during a fire. In addition to being fire-proof, tiles have also been found to provide protection for structural surfaces during fires. (Hygiene) The face of ceramic tiles will not retain liquids, absorb fumes, odors, or smoke. This allows for good hygiene. Tiles are suited for any environment where hygiene is essential. Facts About the Clay Body: The clay body, which is also called the bisque, consists of various types of clay and other minerals. Combined, these raw materials give the bisque its strength and stability. The strength of the bisque is also determined by its density. The strongest bisques, those suited for heavy commercial installations, have the smallest and least number of air pockets. The density of clay also determines if the tile is suitable for outdoor use. Tiles that are too porous, absorbing more than 3% moisture will freeze and crack if installed outdoors in cold climates. The density of the tile is measured by the amount of water it absorbs. · Non-Vitreous Tiles – absorb 7% or more of their weight in water. Suited for indoor use only. · Semi – Vitreous Tiles – absorb 3% to 7% water. Suited for indoor use only · Vitreous Tiles – absorb 0.5% to 3% water. Suited for both interior and exterior use. They are frost resistant. · Impervious Tiles – absorb between 0 and 0.5% of their weight in water. Suited for both interior and exterior use. They are frost resistant. They are also considered the strongest tile. Facts About the Glaze: The glaze is a liquid glass that has been sprayed or poured onto the surface of the tile. It is then fused and hardened by means of tremendous heat. The colors of the glaze are made from a mixture of minerals such as gold, silver, zinc, copper, mercury, cobalt and many others. The strength and wear resistance of the glaze is determined by its hardness. The following factors may effect this hardness: · Temperature - The higher the temperature of the kilns (ovens) the harder the glaze. · Colors - Dark color glazes such as blacks and blues are usually softer than light colored ones. · Gloss Levels – Shiny glazes are usually softer than matte or satin finished glazes. Difference between glazed and unglazed tiles: Glazed Tiles – are made the same as unglazed except that a glass wear-layer, called a glaze, is fused to its surface by means of tremendous heat. Unglazed Tiles - are true inlaid. They are simply baked pieces of clay whose colors run throughout the body. Features of glazed and unglazed tiles: Glazed Tiles: · Most glazed tiles are not suited for heavy commercial installations. They are generally suited for light residential to medium commercial use. · Technology for glazes has improved dramatically over the past few years. There are new glazes on the market that are hard and durable enough to use in heavy commercial applications. Advantage of glazed tiles: · The glaze offers the manufacturers the ability to produce an unlimited array of beautiful colors and designs. · The non-porous glaze creates a smooth surface that is practically stain proof. Unglazed Tiles: · Unglazed tiles are the workhorses of the industry. They are generally thicker and denser than glazed tiles. Some common types are quarry tiles and porcelains. · The tough inlaid qualities of most unglazed tiles makes them ideally suited for, but not limited to, extra heavy commercial installations. · Many customers appreciate the natural qualities and beauty of unglazed tiles and choose them for residential areas. · Generally, the color range of unglazed tiles is limited to the natural colors of clay…ranging from a light sand to a red brick, but there are exceptions. · Some manufacturers achieve a wide range of beautiful colors by mixing color pigments in the clay. Advantage of unglazed tiles: · Superior strength for heavy commercial use as well as residential. · The rugged surface texture and matte finish of the unglazed tile give them superior “slip resistant” qualities for use in wet areas. Gloss Levels: · Glazed ceramic tile varies in gloss levels depending on the look the manufacturer wants to achieve. Levels can range from matte, satin, or high gloss. · Generally speaking, the higher the gloss, the softer the glaze. Areas of the home that don’t receive heavy wear, such as bathrooms, use a higher gloss level than heavy traffic areas such as kitchens. Facts About Floor And Wall Tile: Wall Tile: · Any ceramic tile is suitable for walls, but the very thin, high glossed and decorative tiles are most commonly used. · The most popular size for wall tile is still 4 ¼” x 4 ¼”, but there appears to be a trend taking place for larger, more luxurious tiles. · Wall tiles have a very soft glaze and porous body and therefore should never be used on floors or for outdoor applications. Floor Tile: · These tiles, glazed or unglazed, have sufficient strength, impact and abrasion resistance to withstand weight and foot traffic. · They are usually thicker, denser and heavier than wall tiles. · If the substrate is strong enough to support the weight, floor tiles may also be used on walls and counter tops. (SHADING AND SIZING) Shading: · Many tiles, both glazed and unglazed, are deliberately produced with a wide shade variation to capture the natural beauty of the product. · A certain degree of shade variation is inherent in all ceramic tile. · The manufacturers limit the amount of shade variation within a carton by sorting the tile as it comes off the production line. Also, the shade and run numbers are marked on each carton. · To minimize any noticeable shade variations, the installers work out of several cartons simultaneously. In doing so, they are able to blend the tiles together. Sizing: · The sizes of the tiles will vary slightly. This is inherent with most tiles. · Most manufacturers will keep sizing to an acceptable level by sorting the tile by size prior to packing it. · The grout joints will conceal slight size variations. NOTE: If either the sizing or shading is too apparent, the installer should not set the tile. Normal vs. Actual Sizing Although most tile is advertised and sold by nominal sizes such as 8”x 8” or 12”x 12” the actual sizes will be more like 7 7/8” x 7 7/8” or 11 7/8” x 11 7/8”.
