  • the mating abutment surface / counter thrust surface forms a kind of stop. It prevents the locking spring can penetrate deeper into the Verrieglungsnut; otherwise, the locking spring could act like a wedge and cause it to widen due to deeper movement into the locking groove.
  • the panel core should be made of moisture-sensitive material and it is provided with locking means.
  • the known panel on its top panel has a wear layer in the form of an elastic surface layer. In the area of the elastic surface layer sealing means are provided to prevent the penetration of moisture down to the panel core.

  • the sealant can be introduced during the production of the panels, if the seal groove is made for example by a milling process, then the sealant can be introduced or applied automatically after milling.
  • the sealant may be of any suitable material and may have different consistency depending on the application. So it is also possible to match the consistency / softness of the sealant on different panel core materials.
