An improved separator for separating lumber in a stack of a plurality of layers has a primary profile for minimizing the contact area and maximizing airflow between the separator and the adjacent boards and a secondary profile for improving frictional resistance between the separator and the adjacent boards. The primary profile comprises a plurality of grooves and a plurality of ridges formed therebetween. The secondary profile comprises a plurality of depressions on the ridges. |
