technical features


Glazed tiles and glazed floor decorations with water absorption E < 0.5 % = Gres Porcellanato Smaltato – Group B Ia, with parameters conforming to EN 14411, Annex G. These tiles are designed for interior and exterior tiling in residential housing and public utility buildings. The tiles are characterized by low water absorption, high resistance to bending, high hardness and resistance to abrasion.

Abrasion resistance (PEI)

The abrasion resistance of glazed tiles is one of the decision-making parameters for the choice of an appropriate tile. Abrasion resistance marks the resistance of the tile surface to mechanical wear and tear. The higher the mechanical and pollution exposure of the floor and pedestrian traffic, the higher abrasion resistance is desired. Particularly hard dirt particles from streets or gardens gradually abrade the surface of tiles and irreversible changes in their appearance may occur. The standard EN ISO 10545-7 classifies abrasion resistance with classes/degrees from 0 to 5.

PEI classification and recommended application
PEI 0Not recommended for floors at allinterior vertical tiling, non-trafficable areas
PEI 1Light duty floor with rare traffic without risk of scratchinginterior vertical tiling, bedrooms, soft sole shoes
PEI 2Light duty floor with rare traffic and small pollutioninteriors of flats not directly connected to the outside areas
PEI 3Medium duty floors with moderate pollutioninteriors of family houses, hotel rooms etc. not directly conncted to the outside areas
PEI 4Heavy duty floors with busy traffic and higher pollutioninteriors of offices, hotels, shops in shopping malls, entrance areas of family houses, balconies, terraces, less exposed exteriors
PEI 5Extra heavy duty floors with high exposition to abrasioninterriors and entrances of shops, restaurants, public buildings, staircases, exteriors

The information about abrasion resistance is indicated next to the floor tile picture.

Slip resistance

For some areas, the safety consideration is even more critical than for others. There is a responsibility for stakeholders involved in specifying flooring products (manufacturers, architects, distributors, installers etc.) to ensure that the surfaces are fit for the purpose and do not pose a safety risk for the users.

There is no uniform testing method in the EU and there are different requirements defined for anti-slip tile surfaces for areas walked on when wearing shoes (DIN 51 130) or when barefoot (DIN 51 097). Both tests are done on an inclined plane.
