The method involves applying synthetic resin layers (3) on an upper side and/or lower side of a mounting plate (1) that is made of a wood material or a mixture of wood material and plastic material. The composition of the synthetic resin layers is pressed under the effect of pressure and temperature, where one of the synthetic resin layers expands during the pressing process. The expanded layer is made of froth polyurethane or mixture of urea and/or melamine resin and/or phenolic resin, and a froth additive is added to the expanded layer, where the additive contains azodicarbonamide. An independent claim is also included for a building board with a mounting plate. |
