Construction parameters such as the thickness or weight of a floor covering clearly describe and identify a product.
In addition to these characteristics, geometric dimensions such as size and format also play an important role. During installation, the accuracy of fit and how easy the material is to work with are particularly important.

Suitable product types

  • Textile floor coverings
  • Resilient floor coverings
  • Laminate floor coverings
  • Modular floor coverings with mechanical locking system (MMF)
