The Tile Rating System: PEI

There are 5 types of tile rating which are used by the manufacturers. This rating is not used to classify the quality of the ceramic and porcelain tiles but to help categorize which specific tile should be selected for a particular use. This rating system differentiates the tiles that look same but vary in prices. Some tiles are manufactured for light traffic areas whereas some tiles are manufactured for extreme traffic areas like shopping malls, airports or any commercial place.

Contractors and building owners uses this rating system helping them to analyse which type of tile will best meet their expectation and requirements. Below is a comprehensive chart which will illustrate the difference between each PEI rating.

Class 0	No foot traffic	Use these tiles for wall tile only.  These tiles should never be used as floor tiles
Class 1	Very light traffic	Walk on these tiles with bare feet only.  Used in master bathroom floor tile
Class 2	Light traffic	Walk on these tiles with soft-soled shoes or slippers.  Use in bothroom flooring
Class 3	Light to moderate traffic	These tiles are used in any area of residences but ar enot suitable for entrances or kitchens where there is more traffic in that area
Class 4	Moderate to heavy traffic	These tiles are excellent for entrances and kitchens and where dirt and abrasive substances clinging to shoes may be encountered.  This rating is also good for counter-tops
Class 5	Heavy traffic	This is the tile rating for tiles to be used in entrances, high traffic areas, and commercial buildings subject to heavy foot traffic.

When large white porcelain floor tiles are concerned, a PEI rating should be known at the time of making a purchase. Normally all contractors are aware of the tile ratings but many of the people who are not familiar with this should consult a tile specialist.
