Abrasion resistance (PEI)

In accordance with the European standard EN 102, tiles abrasion resistance is marked as PEI. 
This coefficient is applied to only glazed ceramic and stone tiles and determines the degree of abrasion resistance of glass, which, according to the assumed load on the floor, is divided into 5 groups:

Group 1 (PEI 1): premises with minimal load;
Group 2 (PEI 2): premises for walking wearing home shoes;
Group 3 (PEI 3): all living premises, hotels, small offices;
Group 4 (PEI 4): living and public premises with moderately intensive load;
Group 5 (PEI 5): living and public premises with intensive load.

When selecting ceramic tiles  several basic rules should be taken into consideration:

Dark shades make the space smaller, light ones – on the contrary, visually widen the space. 
A vertical pattern “lifts” the ceilings, a horizontal one – “moves” the walls. 
Large clear patterns give the room solidity and, at the same time, reduce it.
Glossy tiles increase the space (you should be careful with it, since blinks make the eyes tired).

An unusual interior can be created with the help of combinations of tiles with different patterns and colors.

Selection of tiles

Recommendations regarding selection of tiles for kitchens or bathrooms.

Almost all types of tiles are suitable for bathrooms. 
It is important that they have high resistance to household chemicals and can be thoroughly cleaned and disinfected using special means.

Recommendations regarding selection of tiles for living rooms. 

Floor in the living rooms, in comparison with the floor in the kitchens and in the halls, is affected by less load, abrasion and pollution, therefore, here tiles with even PEI 3/750 can be used. 

Recommendations regarding selection of tiles for the outside use or for terraces. 

Terraces that connect gardens or premises with the house are affected by big variations of temperatures. 
Sand, gravel and other abrasive factors can also affect this. Terrace tiles should be frost-resistant, with an abrasion class of at least PEI 3. 

Laying tiles on the terrace, clearance expansion should be taken into account and appropriate isolation and densification should be applied. 

Use of small and large tiles

Ceramic tiles due to their variety can be used in any room. 

Small tiles visually enlarge the space. Therefore, they are suitable for mall rooms, like bathrooms, or small halls. 

When selecting tiles for a large living room or a premise, we recommend to give preference to large tiles. 
Large-format ceramic tiles are ideal for spacious interiors - both floors and walls, creating a uniform surface and optically increasing the area.
Attention must be paid to laying large format tiles on the floor in small rooms - the gaps between the slabs will be clearly visible.
