TYPES OF TILES
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 0 | Not recommended for floors at all | interior vertical tiling, non-trafficable areas |
| PEI 1 | Light duty floor with rare traffic without risk of scratching | interior vertical tiling, bedrooms, soft sole shoes |
| PEI 2 | Light duty floor with rare traffic and small pollution | interiors of flats not directly connected to the outside areas |
| PEI 3 | Medium duty floors with moderate pollution | interiors of family houses, hotel rooms etc. not directly conncted to the outside areas |
| PEI 4 | Heavy duty floors with busy traffic and higher pollution | interiors of offices, hotels, shops in shopping malls, entrance areas of family houses, balconies, terraces, less exposed exteriors |
| PEI 5 | Extra heavy duty floors with high exposition to abrasion | interriors 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.

| R 11 | > 19° – 27° | increased | kitchens, laundries, workshops with wet surface |
| R 12 | > 27° – 35° | high | large kitchens, dairies etc. |
