Page 515 sidebar, "Doors, Gates, and Walls" states that a wooden door has a hardness of 10 and 40hp, while a reinforced wood door has a hardness of 15, and 60hp.
Page 577, table 11-4: Material Hardness, Hit Points, and Broken Threshold states that a Simple Door (an example for "Wood"), has a hardness of 5 and 20hp, while a Reinforced Door (As an example of "Wooden Structure") has hardness 10 and 40hp.
