In addition to the design and color, we should also pay attention to other things in order to buy ceramic tiles. All manufactured tiles have special characteristics, including the place of use (outdoor, indoor, industrial, public places) - wall or floor - coefficient of friction (loss rate) - abrasion rate - water absorption rate and the degree that is usually The code is written on the packaging box.
Ceramic tiles available in the market are often divided into two types, glossy or non-glossy, based on which they have special characteristics (grade, water absorption, friction coefficient, degree of abrasion, resistance to cold). Note that floor tiles can be used on the wall, but wall tiles cannot be used on the floor.
* Degree:
One of the most important factors in choosing a tile is grade. Always in first grade tile production, the highest quality of the products is the highest, and as the value of this number increases, the quality of the product decreases.
Often products produced with quality grade 1 and 2 are suitable for use on the floor. will be
"abrasion degree"
In PEI (Porcelain and Enamel Institute) standard ceramic and tile products, it is the degree of abrasion of the products. Note that the higher the quality of this number If it is wet, the tile has more resistance to abrasion. Only glossy tiles have this type of rating, and if you are going to buy a non-glossy tile, you will not find such a rating on its label. Considering that the tiles used In the wall, they do not need to be highly resistant to wear and tear, and they are more decorative. You can use quality grade 1 and 2 and save money. They are resistant to wear and tear, so they are more suitable for use in residential spaces. Tiles with a quality grade of wear of four have a very high resistance to wear and are suitable for use in all residential spaces and some commercial spaces (spaces where traffic is They are less. The tiles whose quality degree of abrasion is five have the highest resistance in the quality degree of abrasion and are suitable for use in all commercial spaces.
" Water Absorption Degree"
Tile water absorption rate is another important classification in choosing ceramic tiles when buying tiles, which should be considered when buying. Pay attention.
This type of quality grade gives you information about how to choose tiles according to the humidity in that place of use. There are four types of categories in this type of grading, in which the name and percentage of water absorption of a tile are expressed, the lower the amount of this number, the lower the amount of moisture penetration into the tile. The percentage of its weight absorbs water, these types of tiles are not suitable for use in outdoor and wet spaces (such as bathrooms and toilets). Semi-glass tiles that absorb water between 3 and 7% of their weight and are only suitable for use in dry indoor spaces.
Glass tiles absorb water between 0.5 and 3% of their weight. This type The tiles are called ceramic. Ceramics can also be used on the floor and will satisfy your needs in tiling your home. Glass tile absorbs less than 0.5% of its own weight of water and is classified as non-permeable.
*️⃣ Friction coefficient (Lissey scale):
Coefficient of Friction (C.O.F.) refers to the tile's resistance to slipping. The higher this coefficient is, the floor that is carpeted with this tile has a higher safety factor against slipping (in correcting the possibility of people slipping). If you are going to buy tiles for your bathroom, be sure to pay attention to its coefficient of friction. The higher this number is, the more likely people will slip on it when leaving the bathroom. The types of tiles will decrease.
Note that a friction coefficient of more than 50 is suitable for residential use and a friction coefficient of more than 60 is suitable for commercial use.
*️⃣ resistance to cold:
If you intend to use tiles in the outdoor space, this grading is of particular importance. Cold resistance provides you with information on whether the tile in question has the ability to withstand cold or not. If you want to use the desired tile in interior spaces, this grading is not very important.
