A board for construction, consisting of a body of suitable length, of straight generatrices and constant cross section and presenting a plane of symmetry, characterized by a flat central laminar part, which contains the said plane of symmetry, on whose longer edges there are paths heads unequal to each other, but of equal wings due to the indicated symmetry, being of these heads the thicker frontal, of smaller flight, and of rounded edges, with its transition zone with the laminar body also rounded, being the opposite head flat by its distal face and slightly inclined by its internal faces or transition to the laminar body in such a way that the thickness in the angles of such transition is somewhat smaller than in the edges, the whole body being formed in a single piece of a material endowed with certain elasticity and flexibility.
