Below you will find an explanation of the ceramic porcelain tiles product and its characteristics. The ceramic porcelain tiles are part of the Scandi-Roc's product range:

Ceramic Porcelain Tiles (Ivory White, Dusty Grey & Dusty Black)

The series is supplied in 20 mm tiles, which are available for outdoor as well as indoor use. Colloquially they are often called ceramic tiles, but the correct technical name is porcelain tiles.

Ceramic tiles are made of clay and are fired in kilns at high temperatures; the tiles’ properties depend on the composition of the clay mixture as well as the firing temperature: the higher the firing temperatures are, the denser and least water-absorbing the tiles will become.

Porcelain tiles are a ceramic product consisting of kaolinite clay, feldspar and quartz. After being compacted under immense pressure in a form, the tiles are fired. This takes place in kilns where the temperature is slowly increased to 1200–1400 degrees Celsius. Afterwards the kiln is rapidly cooled down, which transforms the clay into glass. This process is called sintering. The water absorption is less than 0.5%, which is the characteristic of a porcelain tile. The production technique makes it harder to produce a porcelain tile compared to a regular ceramic tile.

The ceramic porcelain tiles are frost-proof, acid-, chlorine- and oil-resistant. This makes them extremely maintainable and they can even withstand high-pressure cleaning.

The tile breaking strength as well as the general properties as described for 20 mm ceramic porcelain tiles makes this type extremely useful for outdoor and indoor tiling. Outdoor tiles are frost-proof and can - due to their enormous strength - be used on the terrace, in the driveway (requires concrete pad) and on the balcony. The outdoor tiles are easy to lay and can be laid on a variety of pads. They can easily be laid directly on grass, sand, gravel or they can be glued onto a concrete pad. Exactly as it is done with common concrete tiles or natural stone tiles. In addition, they can also be laid on small special units for, among other things, balconies.

Below we have described and explained the natural occurrences/characteristics that are found in the different stone types, and which one should be aware of when choosing the stone type, as these should not be mistaken for errors eligible for complaints.

Colour variations

Ceramic porcelain tiles are made from natural materials, where every single production/firing is unique and there may therefore be minor deviations in colour tone, surface and structure from each production run.


As porcelain tiles are extremely hard to cut, we recommend the use of suitable tools for this purpose. 

Natural waste

Since we are dealing with a natural product, one must accept that there may be stones that are damaged in one way or another. Production and transport is associated with a great deal of handling. Within our industry a waste of up to 6% is accepted, the occurrence of which you as a customer must accept. This is especially true for larger shipments, where we recommend that this is included in the calculation. Tiles that are sorted out can be used e.g. at cutting etc.


Tolerances of +/-2 mm in comparison to stated measurements should be accepted.
