Indispensable for a long life: frost-proof balcony tiles

In the Central European latitudes, frost is to be expected every winter and therefore the balcony tiles must be prepared for it. With stone and ceramic tiles, the degree of water absorption is decisive, with wood the impregnation and type of wood.

Water absorption capacity of natural stone and wood

The manufacturers of stoneware mark their frost-proof products with a stylized ice flower. These balcony tiles always belong to the water absorption group one A or B. This classification guarantees a water absorption of less than three percent. In the frosty season this amount is too small to turn the freezing water in the balcony tiles into small "mines" that can blow up the stone or ceramic.

When choosing natural stone for the balcony tiles, soft stones such as limestone and sandstone are usually not frost-proof, which also applies to some types of marble. In most cases, granite, porphyry and basalt are naturally frost-proof. The manufacturers test their products and divide them into the groups frost-proof, conditionally frost-proof and not frost-proof.

Wooden balcony tiles must be made from hardwood species and, in many cases, have to be pretreated. Typical methods are pressure impregnation and thermal treatment with heat. As with stone, it is important to reduce water absorption, which is also supported by avoiding stagnant backwater.

Frost-proof accessories and assembly

In addition to the tiles themselves, the quality and type of accessories and the professional installation are decisive for the frost resistance of the balcony tiles.

  • Both the tile adhesive and the grout (€ 6.99 on Amazon *) must be frost-proof when dry so that the frost-proof balcony tiles do not come off.
  • Since a gravel bed can rarely be used as a frost barrier on a balcony, the subsurface must be laid out professionally and any hollow space avoided.
