Today, the variety of roofing materials is extremely large, which allows you to implement almost any design idea. However, it is ceramic tiles that have not lost their popularity for many years.

Tile wear resistance classes on the PEI scale.
If you chose ceramic tiles when choosing a floor covering, you should definitely pay attention to such a technical parameter as the wear resistance class. This is an important characteristic of floor tiles only.
All tiles produced for floor covering are divided into 5 abrasion classes according to the PEI scale.
- PEI I. This coating can be used in rooms with little traffic and where people move in soft house shoes. Can be used in private bathrooms.
- PEI II. Such a floor can withstand an average load. Can be used in all rooms of an apartment or a private house.
- PEI III. A product with this class can withstand a higher than average load. The load is allowed in ordinary shoes, so it is used in offices and corridors.
- PEI-IV. This class mostly defines ceramic granite slabs. It is suitable for premises with high traffic of people, for places of public use.
- PEI-V. The highest class of wear resistance. Withstands almost any load intensity. Such tiles are used for the floors of airports, railway stations, shopping centers, restaurants and parks.
The correctly selected wear resistance class of the tile plays an important role in the further operation of the floor covering. If you choose a PEI grade that is not high enough for a specific room, the surface will eventually scratch, the glaze may wear off, and the clay base of the tile will be visible.
How are tile abrasion tests performed?
To determine the wear class of the tile, tests of this material are carried out. For this, the surface of the tile is exposed to the influence of a special disk that rotates using special abrasives (metal crumbs, corundum dust and water) at a speed of 300 revolutions per minute. Next, from the height of human growth, visible scratches on the tile are determined after a certain number of revolutions of the disc. The higher the number of rotations the tile glaze can withstand, the higher the wear resistance class the tile will receive.
The main parameters for the correct choice of floor tiles.
In order to choose the right floor tile, it is worth assessing the traffic intensity and the room's passability, what kind of loads the floor must withstand, what type of pollution will be in this room.
According to these indicators, the required class of wear resistance is chosen.
However, this is not the only parameter that you should pay attention to when choosing a floor covering.
Covering the surface of the tile is an important nuance for the floor. Glossy, matte, embossed or semi-polished — you should understand which one will be best for your room. Glossy is an attractive shiny material, which is suitable for a bathroom or any room where there will be even minimal contact with water. Matte ceramics have a rough surface. Although it does not have a shine and does not reflect light, it has a pleasant texture, is safe and non-slippery. Therefore, it is most often used for the floor.
Another important parameter is resistance to the influence of chemically active substances. There are also 5 classes here. AA is the highest class, a tile with this mark does not change in any way under the influence of chemicals, it can be safely washed with any chemical means. Class D is the lowest, and it means a complete loss of appearance. For the floor, choose class A and AA, then you will be calm about the appearance of the floor surface after washing.
Frost resistance is also an important parameter for the floor outside the house. If you decided to cover a balcony, terrace or utility room outside, be sure to pay attention to the frost resistance mark on the package - it's a snowflake. Then the floor will not be afraid of repeated freezing and separation.
Sliding coefficient: the degree of sliding is indicated by the index R with a number that shows at what angle the tile will prevent sliding. Example:
- R9 is perfect for residential and public spaces.
- R12 — in addition to the previous option, can be used for floors in food factories, for specialized medical premises.
- R13 is the highest anti-slip coefficient.
Tile thickness: the thicker the ceramic tile, the more load it can withstand. It is especially important to take this into account if you cover the floor in production premises. Of course, a smaller thickness will be enough for private housing.
