IS 1659
Block board
Block board has a core of solid wood strips (battens) glued edge to edge and faced with veneers on both sides. It is lighter than plywood of the same thickness, does not sag on long spans, and holds screws well, which makes it the usual choice for long shelves, tabletops and doors.
