A tile system for covering a surface. The tile system comprises a first tile assembly connected to a second tile assembly by a connector. Each tile assembly comprises a first tile stacked on a second tile, the first tile and the second tile joined to a reinforcing material disposed therebetween. The connector comprises a first component and a second component that is complementary to the first component. The first component is mounted to the first tile assembly, and the second component is mounted to the second tile assembly.

A rectangular panel which, on the first and on the second pair of opposite edges, has coupling parts configured for easy installation in a wall or ceiling covering. A locking occurs between the coupled panels; and a wall or ceiling covering that includes such panels.

A method for manufacturing a laminate includes a carrier material and a cured thermosetting resin. The resin is cured using a catalyst showing one or a combination of two or more of the following properties: the catalyst has a pressure activatable catalyst; the catalyst has an encapsulated catalyst; the catalyst has an organic carboxylic acid. A method is provided for impregnating a paper layer, and an aminoplast resin catalyst is used in the method.

A rectangular panel which. on the first and on the second pair of opposite edges, has coupling parts configured for easy installation in a wall or ceiling covering. A locking occurs between the coupled panels; and a wall or ceiling covering that includes such panels

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue arranged in a displacement groove having a first opening at a first edge of a first panel. The tongue is configured to be displaced in the displacement groove along a displacement axis to attain a locking state wherein a first portion of the tongue cooperates with a first tongue groove having a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. A second portion of the tongue is configured to cooperate with the second edge of the adjacent second panel via an elongated element for vertical unlocking of the first and the second edge.

A set of essentially identical panels, such as building panels, provided with a mechanical locking system including a displaceable tongue, which is arranged in a displacement groove with a first opening at a first edge of a first panel. The displaceable tongue is configured to cooperate with a first tongue groove, with a second opening at a second edge of an adjacent second panel, for vertical locking of the first and the second edge. The height of the first opening is greater than a second height of the second opening.

A floor board including a decorative surface layer applied to a substrate, where the substrate is optionally MDF or HDF material at a side edge thereof, and at least one side edge together with a side edge opposite thereto forming a first pair of opposite side edges of said substrate. The first pair of opposite side edges includes mechanical first and second coupling parts, respectively, allowing the floor board to be coupled at the respective side edges with a similar floor board. Also, a floor board covering consisting of a plurality of the floor boards and a method for manufacturing such floor boards.

A building panel, such as a floor panel, or wall panel, having a multi-layered substrate including a back side layer comprising lignocellulosic particles and a binder, an intermediate layer comprising lignocellulosic particles and a binder which is arranged on the back side layer, and a front side layer comprising lignocellulosic particles and a binder, and which is arranged on the intermediate layer. The back side layer was formed from a first mixture, the intermediate layer was formed from a second mixture and the front side layer was formed from a third mixture. The building panel further has a mechanical locking device arranged along at least one edge portion of the building panel where the mechanical locking device is configured for horizontal and/or vertical locking of similar or essentially identical building panels in an assembled position.

Building panels, such as a floor panels or wall panels. The panels including a first mechanical locking system at respective parallel and opposite third and fourth edges, such as long edges, configured to cooperate for horizontal and vertical locking between two adjacent building panels, preferably by means of a folding motion. The panels further including a second locking system at respective parallel and opposite first and second edges, such as short edges, configured to cooperate for horizontal and vertical locking of two adjacent building panels. An upper edge portion of one of the third edge or fourth edge, preferably the third edge, includes a first lower lip portion configured to cooperate with a first upper lip portion of an upper edge portion of the other of the third and fourth edge of an adjacent panel when the third and fourth edges are arranged in locking engagement.
