A floorboard, includes a carrier plate and a veneer arranged on a topside of the carrier plate, wherein the carrier plate and the veneer are connected with each other via a resin, wherein an edge strip made of the resin is provided on at least two side margins of the veneer, and wherein a surface of the edge strip extends in a same plane as a surface of the veneer.

A floor, wall, or ceiling panel has a base made of a wood material and an upper veneer. The base and the veneer are hot-pressed together while incorporating a resin layer. During the pressing process, pores, cracks, and/or gaps in the veneer are filled with resin. In particular, the pressing process is carried out such that the veneer is saturated with resin, and the resin can be seen on the surface of the veneer after the pressing process The adhesion of the veneer to the base and the smoothing of the veneer are thus carried out in one operation.

The present disclosure relates to a panel comprising a structured lacquer surface, having a base panel, a melamine resin layer, an adhesion promoter layer and a lacquer-containing top coat, the melamine resin layer being provided on a surface of the base layer, the adhesion promoter layer being provided on the melamine resin layer and the lacquer-containing top coat being provided on the adhesion promoter layer, the lacquer-containing top coat being structured. The disclosure also relates to a method for producing a panel of this type with a structured lacquer surface.

Sheet material includes at least two layers of material, wherein a first layer of material forms more than half the thickness of the sheet material and is mainly built up from wood particles glued by means of a first binder and pressed. The first binder is thermosetting, wherein the second layer of material is present on the surface of the aforementioned sheet material and is mainly built up from particulate particles glued by a second binder and pressed. The second binder is thermoplastic and/or elastomeric.

A method of manufacturing a building element, including applying a first layer on a first surface of a substrate, the first layer including a mixture of a binder, at least one filler and fine non-pigment cohesive particles, wherein an amount of the fine non-pigment cohesive particles in the mixture may be between 0.05 wt % and 9 wt % of the mixture, and applying heat and/or pressure to the first layer and/or the substrate thereby forming the building element. The disclosure further relates to such a building element.

A laminated door core for use in fire rated doors includes a center layer having a first side and an opposing second side, where the center layer comprises fire rated particleboard. The laminated door core also includes a first layer comprising calcium silicate adhered to the first side of the center layer, a second layer comprising calcium silicate adhered to the second side of the center layer, a first layer of high-density fiberboard adhered over the first layer of calcium silicate, and a second layer of high-density fiberboard adhered over the second layer of calcium silicate. A vertical stile may be positioned along each opposing longitudinal edge of the laminated door core, and a horizontal rail may be positioned along each of a top end and a bottom end of the laminated door core.

In a first pressing stage, constituting preliminary pressing, glued layers forming a single multi-layer floor panel (1) are pressed for a time between 5 and 50 seconds, until a physical, local joining of the layers is obtained allowing determination of the position of the sheets of solid wood constituting a top layer (4) being placed on a core composite layer (2) covered with an adhesive. In the next stage, a stack is formed from numerous floor panels (1) thus pressed, after which the said stack of preliminarily pressed floor panels (1) is subjected to pressing, constituting main pressing, for a time longer than 300 seconds, until the adhesive bond of the required durability and strength is obtained, wherein the adhesive (3) applied to the core composite layer (2) is a hot-melt polyurethane adhesive.
