PEI is the abbreviation for Porcelain Enamel Institute. A PEI Rating is given to a tile product based the hardness of its glaze. This hardness is determined by the manufacturer using a standardized test.
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 âthrough bodyâ porcelain tiles do not have a PEI rating (as they are very hard wearing).
