PEI classes range from 0 to 5. The Porcelain Enamel Institute rating scale is not a measurement of quality. It is a scale that clearly indicates the areas of use each manufacturer recommends and has designed their tile to fit. A PEI 2 tile has been designed for areas where very low traffic and soiling is anticipated. In most cases the aesthetic detailing of these tiles is of prime consideration. You will often find high gloss levels, vibrant colorations and metallic elements in this group of tile. Conversely, a PEI 5 tile has been designed for abusive extra heavy foot traffic. The technical aspects such as surface abrasion resistance will be considered and must be achieved first before aesthetic effects are incorporated.
Class 0 – No Foot Traffic:
Wall tile only and should not be used on floors.
Class 1 – Very light traffic:
Very low foot traffic, bare or stocking feet only. (Master bath, spa bathroom).
Class 2 – Light Traffic:
Slipper or soft-soled shoes. Second level main bathroom areas, bedrooms.
Class 3 – Light to Moderate Traffic:
Any residential area with the possible exception of some entries and kitchens if extremely heavy or abrasive traffic is anticipated.
Class 4 – Moderate to Heavy Traffic:
High foot traffic, areas where abrasive or outside dirt could be tracked. Residential entry, kitchen, balcony, and countertop.
Class 5 – Heavy Traffic:
Ceramic tile suggested for residential, commercial and institutional floor subjected to heavy traffic.
