What is the PEI rating?
The PEI (Porcelain Enamel Institute) rating on tiles refers to the wearability of the glaze, and therefore what applications the tiles are suitable for. Low PEI glazes are often high gloss or metallic finishes or high copper content colours. High PEI glazes are very resistant to abrasion, and can be used in many different environments. • PEI 0 – Wall use only – This is not suitable for use on the floor and care should be taken with abrasive cleaning products • PEI 1 – Very light traffic – Bare foot traffic, only – ensuite shower rooms etc • PEI 2 – Light Traffic – Soft soled shoes only – House bathrooms, bedrooms • PEI 3 – Light to Moderate Traffic – Most residential areas apart from entrances. • PEI 4 – Moderate to Heavy Traffic – High residential foot traffic areas including entry ways.
