Abstract

A longitudinal laminate board of binder fixed mineral wool. The laminate board consists of adjacently disposed longitudinally directed pieces, whose fibre planes form a right angle to the plane of the laminate board. The length of the pieces is less than half of that of the laminate board and they are jointed to each other. None of the joints is immediately next to any of the ends of the laminate board or to any of the supports for the board.
