A panel comprising a heat providing layer is presented. The panel includes panel coupling means arranged for coupling the panel to adjacent panels. Longitudinal grooves are arranged in the panel along the whole length of the panel. In order to provide heat, at least one electrical end connector is arranged at one or more end panel coupling means. The electrical end connectors are arranged for being electrically connected to the heat providing layer, for being at least partly electrically conductive, and for at least partly protruding from the one or more end panel coupling means, thereby providing an electrical connection between the heat providing layer of the panel and a corresponding heat providing layer of at least one adjacent panel coupled to the panel. The invention also concerns a heating system comprising such a panel, the electrical end connector, and a method for installing such a heating system.

The invention relates to a multi-purpose tile system, in particular a floor tile system, comprising a plurality of multi-purpose tiles. The invention also relates to a tile covering, in particular floor covering, consisting of mutually coupled tiles according to the invention. The invention further relates to a tile for use in multi-purpose tile system according to the invention.

Floor panels are shown, which are provided with a mechanical locking system that may be locked with a vertical displacement of a first panel against a second panel. The locking system includes a flexible strip that during locking bends upwardly or downwardly. The locking system includes a first and a second joint edge section with different locking functions. One section provides a horizontal locking and another section provides a vertical locking.

A floor panel for forming a floor covering, wherein the floor covering consists of floor panels, which, on at least one pair of edges, are provided with coupling parts. The coupling parts substantially are manufactured from the material of the floor panel, and the coupling parts are configured such that two such floor panels, at the pair of edges, can be installed and locked to each other by means of a downward movement and/or by means of the fold-down principle.

A floor panel for forming a floor covering, wherein this floor panel is at least composed of a substrate; wherein the floor panel, on at least one pair of opposite edges, comprises coupling parts, which coupling parts allow that two of such floor panels can be coupled to each other by means of a downward movement of one floor panel in respect to the other floor panel; wherein these coupling parts, in the coupled condition of two of such floor panels, form a first locking system, which effects a locking in a first direction perpendicular to the plane of the floor panels, and form a second locking system, which effects a locking in a second direction perpendicular to the edges and in the plane of the floor panels.

A floor panel for forming a floor covering consisting of floor panels which are provided with coupling parts on at least one pair of edges. The coupling parts are made mainly of the material of the floor panel, and the coupling parts are configured such that two of such floor panels can be installed and locked together at the pair of edges via a downward movement and/or via the fold-down principle.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.

A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

The invention relates to a panel with complementary locking means provided in pairs on opposite panel edges. One of the locking means is hook profiles with a receiving hook and a locking hook. The free step end of the locking hook is designed narrower than the width of the receiving opening of the receiving hook. The locking contour of the locking hook protrudes at least partially past the plane of the joint surface of the receiving hook so that the free step end fits into the receiving opening far enough at first that a part of the horizontal locking surface of the locking hook makes contact with the horizontal locking surface of the receiving hook during a joining motion without elastic deformation of the hook profiles, and that the receiving hook bends so that the width of the receiving opening can be expanded so that the locking step can be inserted entirely into the receiving recess and the locking contour of the locking hook is further inserted into a form-fit contour of the receiving hook.
