A frequently asked question when explaining the nature of the frost resistance of ceramic tiles is the minimum temperatures to which a given ceramic tile is adapted. This query results from comparing the tiles to a completely different assortment at which the maximum cold limit is justified. Taking as an example the liquid for car windows, it can be concluded that the concept of frost hardiness should actually be accompanied by some specific value expressed in temperature units.
Nothing could be more wrong – the frost resistance of the tiles, in the simplest terms, is their resistance to multiple passage through the 0 °C limit. As you know – below this limit water begins to freeze, so the liquid state goes into a solid state. The water entering into the gaps turns into ice, which literally bursts the material from the inside. This phenomenon can be observed, for example, on the example of Polish roads which are repaired after the winter due to damage to the surface. Ceramic tiles with a compact structure, i.e. tiles, clinker, and floor tiles, due to the compact mass, do not absorb water, so it has no chance to penetrate the structure to such an extent that it can be damaged after going into solid state. Each assortment with water absorption E≤3% is considered frost-resistant.
The conclusion is that frost-resistant tiles are not exposed to damage due to extremely low temperatures, and because of the large number of cycles of freezing and thawing of water, which changes its state from liquid to solid and vice versa. In practice, this means that the location of frost-resistant tiles in Siberia is less burdensome for them than using them in a climate typical for Poland. Frost resistant tiles produced in Poland are intended for use in harsh weather conditions and will work better in this respect than any other.
