  • decoupling is understood in the present application, the reduction of shear stresses or stress peaks between two arranged in a solid composite layers. An effective decoupling thus prevents existing shear stresses or stress peaks in one of the layers from transferring to the other layer of the composite structure and causing damage there.

If no decoupling web is laid between the tile floor and the young screed, the tiles, especially due to their low expansion coefficient, could not follow the movement of the screed so that shear stresses develop which ultimately lead to detachment or even tearing the tiles can lead. Even when laying coverings on especially critical substrates, such as old wooden floors, decoupling sheets are required.
  • a decoupling web of the aforementioned type compensates for these shear stresses by deformation, which is why damage to the composite structure is not to be feared.
