What is the difference between standard “ceramic” tiles and porcelain tiles?

The concept of ceramic tile in a broader sense encompasses all types of tiles that are made of clay or a mixture of clay with other natural materials, and then kiln-fired. The two basic subgroups of ceramic tiles are porcelain and non-porcelain tiles, which differ in the material itself, manufacturing technology, technical properties and purpose of use. Non-porcelain tiles are usually called ceramic tiles in the narrow sense, and are thus separated from the porcelain.

The main difference between ceramic and porcelain tiles is in the water absorption. Porcelain tiles have extremely low water absorption (less than 0.5%), which is why they are classified as frost-resistant and are also intended for outdoor application. Ceramic tiles, on the other hand, have a higher water absorption, so they are used only indoors.

Gorenje Keramika produces wall ceramic tiles, which are made of red clay and glazed with a durable layer of glaze, which makes the tile surface durable and extremely easy to clean and maintain. These tiles are exclusively designed for indoor wall installation. They are softer and lighter than porcelain tiles, making installation easier and the walls less heavy.

Porcelain tiles are heavier, stronger and more durable than ceramic, so they are also suitable for installation on the busiest walking surfaces or outdoor. Gorenje Keramika offers glazed porcelain tiles that will ensure long-term carefree use.


Why is there so much shade or size variation in my tile?

The body of the tiles is made of completely natural materials (clay, sand), which is transformed into an extremely solid and durable building element by firing at high temperatures. Due to the nature of the material, there are minor differences in dimensions (calibre) and shades, compliance of which is regulated by the European standard EN 14411. When purchasing (or buying more) ceramic tiles, pay attention to matching shades and calibers in all packages - both are listed on the side of the package. Before you install the tiles, we recommend mixing them from multiple different packages and check the shades and calibers before installation. If you are satisfied with the resulting image, only then move on to the installation process.
With the latest trends in ceramics, tiles replicate patterns of nature, accordingly, we offer collections of tiles that contain several diverse faces, which differ in color, shade, or pattern. The variability of these is defined by labels from V1 (uniform appearance) to V4 (stronger shade and pattern variation).


Is ceramic tile a durable material?

Yes, but this depends heavily on the installation. Keep in mind that ceramic tiles are as strong as the surface on which you will lay it. Improperly prepared surface means a greater possibility of damage and detachment of the tiles from the surface. For optimal durability, the installation should be carried out by professionals who are experts on how to lay tiles without irregularities, thus ensuring a sustainable longevity of products.


Are ceramic tiles non-slip?

For glazed porcelain tiles, the anti-slip class is measured in accordance with DIN EN 16165 B, which is a standard by the German Institute for Standardization (DIN). The test method involves a person wearing required footwear and treading on a ramp inclined at various angles. The results acquired with this method are classified into 5 ratings, from R9 to R13, which coincide with the prescribed ramp angles. Category R9 includes glazed porcelain tiles with a lower anti-slip rating (average slip angle between 6-10 °), while  glazed porcelain tiles marked R13 have the highest anti-slip rating (average slip angle above 35 °). The higher the anti-slip rating, the better the grip of the walking surface.
