Roseburg Plywood underlayment is produced using thin layers of wood called veneers that are peeled from a western softwood tree log and glued together to form one multi-layered wood panel. This process creates a very strong plywood underlayment that is engineered to be a durable protective covering and can be applied directly over the floor joist framing of a building. Roseburg Plywood underlayment delivers outstanding stiffness: strength and versatility.
Nails directly over floor joist in 19/32" or thicker panels.
Framing applications where state and/or local building codes require greater construction for extra strength.
Where additional insulation is desired.
