A paper overlaid wood product having a relatively low density. The board includes a core comprised of oriented strand board. A resin impregnated kraft paper overlay is adhesively secured to the top surface of the oriented strand board core. The paper overlaid wood board has a density ranging from about 35 lb/ft3to about 55 lb/ft3, a modulus of rupture (MOR) of from about 3000 to about 9000 psi, a modulus of elasticity of about 0.4 million to about 1.2 million psi, and a thickness of about 0.25 inches to about 1.25 inches.
