The expansion joints are used for
- to install electric cables clever and hidden under the tiles
- to avoid that the tiles do rise in the heat
Advice: If the surface has more than 10 m², we recommend to install an expansion joint that the tiles have the possibility to an extent. You also can put tile on tile – without putting the tiles together loop into pin – you lay the tiles only side to side. Due to this solution, the tiles do not rise by heat, and they do always lay flat.
