PEI Ratings (Porcelain Enamel Institute)

All glazed floor tiles are classified under a Porcelain Enamel Institute (PEI) rating for the suitability of fixing in a particular location. Please note that ‘through body’ porcelain tiles do not have a PEI rating (as they are very hard wearing). Visit our article on the difference between ceramic and porcelain tiles.

PEI Class I

Ceramic tile suggested for residential and commercial wall applications only.

PEI Class II

Ceramic tile suggested for interior residential and commercial wall applications and for residential bathroom floor applications only.

PEI Class III

Ceramic tile suggested for residential floors, light to moderate traffic areas only, e.g. bathrooms, halls, living rooms and wall applications.

PEI Class IV

Ceramic tile suggested for residential floors, moderate to heavy traffic areas, e.g. bathrooms, halls, kitchens, conservatories and wall applications.

PEI Class V

Ceramic tile suggested for all residential floors, medium commercial floors and wall applications.   We recommend the installation of a mat well if application is leading from an external door, this aids in the removal of dirt, water and grit from shoes.
