  • Patent number: 9422727
    Abstract: A joint for panels, the panels comprising a core, a decorative upper surface and edges provided with joining means for positioning the panels towards one another. Predetermined portions of the edges are provided with a layer of polymer. The panels are joined to one another by use of the joining means where the polymer forms a seal in the joint preventing penetration of water into the joint wherein a highly water resistant unit of a plurality of panels is formed.

  • Patent number: 8448399
    Abstract: A thin decorative thermosetting laminate of postforming quality is glued to a longitudinal carrier to form a floor strip. The laminate has a thermosetting resin as well as hard particles impregnated therein to increase the abrasion resistance of the laminate. The carrier generally has a cross section of a dilatation, transition or a finishing profile, depending on the intended use of the floor strip. The floor strip has a tab portion on a surface that engages a channel on a floor tile or a reducer. The tab portion locks the floor strip into place and prevents movement of the floor tile or the reducer with respect to the floor strip.
