As such no tile is manufactured specifically for wall & floor but there are set standards like durability, strength & water absorption which determines how many foot steps a tile can hold apart from that type of application done on glazed surface also determines it's functionality, ties with heavy punch and mostly rectangular tiles are universally accepted for wall where as matt & gloss tiles with vitrfied body and PEI more than 3 are accepted for floor tiles. To know more about PEI or group please refer as follows The tiles are a few different scales and classifications of tile strength, but the Porcelain Enamel Institute (PEI) rating is probably the most commonly used. It rates tiles on a scale from zero to five, and each rating has criteria for their suggested use based on the wear and tear they can handle. Let’s take a look at it in a bit more detail:
- PEI 0: Only wall tiles.
- PEI 1: Mainly wall tile and floor with very low foot traffic
- PEI 2: Floor but should be avoided with heavey items or heavey booth ideal for kitchen, Varanda
- PEI 3: Well suited for livingroom, bedroom and practically anywhere inside home
- PEI 4: Can withstand heavy foor traffic but still limited in application and styles
- PEI 5: Practically withstand all traffic, be it indoor or outdoor like shopping mall, restraunt etc
