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 construction for wall, roof, and floor systems. OSB is also used in applications where a uniform, strong panel is needed, such as industrial packaging and furniture manufacturing.
