How to choose floor tiles

Ceramics rivals laminate in popularity. Already at the subconscious level, this coating is perceived as a reliable and durable material. It should be so, but in reality you can face slippery or fragile tiles, the operation of which brings many problems. To prevent this from happening, you need to make sure that the tile meets the basic criteria.

Slip resistance
If this parameter is not taken into account, the operation of the tile will turn out to be hazardous to health. Many beautiful but slippery tile series are overlooked today. The polished and lapped surface finish has a limited range of applications. Tiles with sufficient slip resistance are best suited for residential and commercial use.

This parameter is determined using a special coefficient obtained according to the methods DIN 51130 and DIN 51097. It is designated by the letter R. European standards provide for classification into groups – from R9 to R13. The higher the indicator, the higher the slip resistance and the more practical the tile. It is fundamentally important to take this parameter into account when choosing a coating for a kitchen, bathroom, hallway, nursery, threshold.

Strength
In the case of tiles, it is appropriate to combine durability and strength. However, even in this case, several criteria need to be considered:

surface hardness – the parameter is measured on the Moss scale, is relevant for glazed tiles, shows resistance to scratching and should not be less than 5 points;
flexural strength is one of the most important indicators of floor tiles, which according to the ISO standard has 3 categories (BIb from 16 to 27 N / mm²) and shows what kind of load a tile can withstand when force is applied at different points;
chemical inertness – denoted by the Latin letters A, B, C, D and shows the ability to maintain appearance and properties after contact with various substances (maximum resistance for tiles of class AA);

abrasion resistance – displays the degree of wear of the coating under the mechanical action of abrasive particles, is applicable to unglazed tiles and is marked with Latin letters and Roman numerals: PEI (I – V).

The highest rates should be for tiles that are planned to be used intensively in public places. When choosing a coating for residential premises, the requirements are less stringent.

Heat resistance
The behavior of a tile when it is cooled or heated largely determines the area of ​​its application. Covers that do not meet the standards are not recommended for outdoor use. When choosing, you need to consider 2 criteria:

frost resistance – the ability to resist the absorption of water by a tile and its further expansion in the pores at temperatures below 0 ° C;
resistance to temperature fluctuations – the tiles are checked by repeated heating and cooling with a difference between the minimum and maximum values ​​of at least 100 ° C, this allows you to evaluate how the ceramics will behave on the street.

Packaging with frost-resistant tiles must be marked with a test carried out in accordance with the requirements of EN ISO 10545-12. When tiles are used in heated rooms, this indicator does not have such a fundamental significance.

Porosity
The ability of a tile to absorb moisture when immersed in water depends on its structure and quality. The higher the porosity, the lower the density. For use in rooms with high humidity, the porosity of the tile should be approximately 3%, for other rooms a coating with an indicator of 6% is suitable.

Tiles of the third group have a limited area of ​​application. For floor cladding, it is practically not used.

Thermal conductivity
This indicator is important when installing a warm floor. In this case, the tile must freely transfer heat from the heating elements. Otherwise, the cost of maintaining a comfortable temperature will increase.

This parameter is indicated by λ, but it is not on the package. However, you can find out this characteristic in another way – the lower the porosity, the higher the thermal conductivity.

Dimensions (edit)
The choice of sizes depends on the area of ​​the room and the requirements for its interior. Tiles with dimensions of 300×300 mm are suitable for bathrooms and kitchens in typical apartments. For corridors, living rooms and bedrooms, tiles with dimensions of 600×600 mm are chosen. Large tiles laid diagonally increase the space visually. At the same time, the ratio of the size of the cells on the floor and the dimensions of the room should not cause a feeling of discomfort.

The recently widespread tiles with non-standard dimensions allow you to imitate parquet or solid boards. It is a versatile floor covering that is suitable for all rooms and can also be used for underfloor heating. The dimensions of such tiles are 600×150 or 600×200 mm.Ceramic tiles Birch Ceramics Sherwood GP (15 tiles)
Tile caliber
Estimated tile sizes differ from real ones. Information about this is applied to the packaging so that you can choose tiles with a difference of no more than one caliber. Otherwise, the quality of the coating may be reduced.

Is it important to follow all the requirements when choosing?
When looking for tiles for indoor use, you can ignore frost resistance and resistance to thermal expansion.

All other criteria are important. Outdoor tiles must meet all of the listed requirements.
