OSB (Oriented Strand Board)
Putnam Lumber distributes OSB by the truckload. OSB is manufactured from wood strands that are arranged
in cross-oriented layers and pressed together with a waterproof exterior adhesive. OSB is widely used in

panel is needed, such as industrial packaging and furniture manufacturing.
