Glazed ceramic tiles are in a class all their own—in fact five different classes. When selecting ceramic tiles for an area of the home, give thought to what that area will be used for, then compare with the rating system to choose an appropriate tile with appropriate surface abrasion resistance.
Glazed Ceramic Tile Classes
Depending on the source, ceramic tiles can have a rating of 0-4 or 1-5. These indicate the scratch resistance and durability of the tile. Consider the latter, 1-5 rating system. In class 1 are tiles that will see no action, meaning they are in a no-traffic area. Where would that be? Unless Spider-man lives in your house, that would mean using this tile on walls only. For example, you could use them to decorate your bathroom walls. Class 2 tiles would be where there is light traffic, for example a bathroom floor, or any place where bare feet or slippers would cut down on the abrasion to the ceramic tile surface. Soiling of the tiles is anticipated, but the main concern is the aesthetic appeal of these tiles. In this class you will find glossy, vibrant colored ceramic tiles. What of Class 3? They would be appropriate in most residential rooms. Class 4 tiles may be seen at an office building, a shopping mall, perhaps even a showroom where there would be light commercial traffic. Class 5 has the toughest surface of them all, where resistance to abrasion is the prime concern and aesthetic appeal is secondary. These ceramic tiles receive the most abuse, being used in airports, subways, fast food restaurants and the like.
Glazed or Unglazed – How To Tell The Differences
You need not be an expert to distinguish between a glazed and unglazed tile. Simply pick up the tile and turn it to the side so you can see it in profile. The body of the tile, called the bisque, is the largest layer. If you see two layers, the tile is glazed. If only one layer is visible, then more than likely the tile is unglazed.
