Do I have to place expansion joints in screed with the Staenis grid?

It is no longer necessary to place expansion joints in your screed with the Staenis grid.


  • An expansion joint must still be placed if the opening is smaller than 110 cm.
  • Surfaces without expansion joints may not exceed 200 m² (for surfaces larger than 200 m², please contact us).
  • Construction joints must always be adopted, as prescribed by the Buildwise.
  • Edge insulation (perimeter joints) must still be placed.
