SUBSTANCE: invention relates to boards, such as floor boards, wall cladding boards and ceiling boards, and to a method for manufacturing these boards. Such boards are characterized by the presence of a peripheral connecting device designed to connect one board to another, the inner layer, which is, for example, made from a material based on wood or fibre, and the top layer applied to the inner layer, which may be decorative and may contain or be a wear layer. Additionally, a bottom layer can be applied on the bottom side of the inner layer, with the specified layer intended for contact with the floor, or an underlayer can be applied during use. Said connecting device contains engaging spikes and latches that interact with each other to provide both vertical and horizontal locking.
