When it comes to using tiles in outdoor areas, frost is a crucial factor that needs to be taken into account. Tiles that are not frost-proof can suffer damage in severe frost, such as cracking or even breaking. Therefore, it is important that frost resistance is taken into account when selecting tiles for outdoor use.
What does frost protection mean?
Frost resistance is the ability of tiles to withstand temperature fluctuations and stress caused by frost. The classification of tiles in terms of their frost resistance is defined in DIN EN 14411. This standard specifies that tiles are considered "frost-proof" if they show no visible changes during a series of freeze-thaw cycles.
There are different types of tiles that are suitable for outdoor use. Some of these tiles are:
- Porcelain tiles
Porcelain tiles are one of the most common types of tiles used for outdoor use. These tiles are very resistant and have low water absorption (less than 3%), which means they do not absorb much moisture and are therefore less susceptible to damage from frost.
- Terracotta tiles
Terracotta tiles are also a good choice for outdoor use as they are very durable and radiate natural warmth. However, these tiles are more susceptible to moisture and must be carefully sealed to prevent damage from frost.
- Ceramic tiles
Ceramic tiles are also suitable for outdoor use if they are frost-proof. These tiles are typically lighter than porcelain tiles and can be made in a variety of colors and patterns.
How to ensure tiles are frost proof
Before choosing tiles for outdoor use, make sure they are frost-proof. It is also important that you source the tiles from a trusted supplier to ensure they are of high quality.
One way to ensure that tiles are frost-proof is to follow DIN EN 14411 . If the tiles meet this standard, you can be sure that they are frost-resistant. It is also advisable to check the manufacturer's specifications to ensure that the tiles are suitable for outdoor use.
In summary, it is important to choose tiles that are frost-proof if they are to be used outdoors. Porcelain tiles, terracotta tiles and ceramic tiles are all suitable options if labeled accordingly. However, before choosing a type of tile, you should ensure that it is of high quality and comes from a trustworthy supplier.
